When a Plugable DisplayLink device is not working as expected with a Windows system, the best practice is to disconnect the device from the host system (and remove it's external power source, if it has one) and perform a 'clean' manual installation of the latest version we recommend of the required DisplayLink software driver to help ensure both are in a good state. To do so, please follow these steps:

1. Disconnect the Plugable USB docking station or video adapter from the host system. If the product you are using has an external power adapter (for example a USB docking station), please also disconnect the power adapter from the product so that the unit resets. Please keep everything disconnected until prompted
2. Uninstall any and all software with 'DisplayLink' in the title that is present from within the Control Panel Programs and Features (Apps and Features in Windows 10). Don't worry if these entries are not present or if the process does not work for any reason, just move onto the next step
3. Download and run the DisplayLink Installation Cleaner utility
   • We have a short video that demonstrates this process
4. Once the cleaning utility has completed running, restart the host system (even if not prompted to)
5. Download and install the latest version (that we recommend) of the DisplayLink software driver
6. If you disconnected the power adapter from your product in step one, please reconnect it so the device powers on, then reconnect the product to the host system. If the product is still not working as expected, please restart the host system one more time.

If, after having completed this process, your Plugable DisplayLink device is still not working as expected, please reach out to us directly via support@plugable.com with the output of our PlugDebug diagnostic utility and we will be happy to help

The graphical software utilities provided by Intel, NVIDIA and AMD/ATI are designed to only recognize and work with graphics adapters made by their respective manufacturers. As a result, they will not recognize USB-attached displays connected to a DisplayLink-based docking station or graphics adapter.

It is recommended to use the facilities built-in to Windows to manage the connected displays. These would be the ‘Display Settings’ application on Windows 10 and ‘Screen Resolution’ application on Windows 8.1 and 7. Both of these applications are available by right-clicking on empty space within the Windows desktop and selecting the appropriate choice from the context menu that appears. 

Note: Intel has released an updated 'Intel Graphics Command Center' application that can recognize DisplayLink-attached displays and configure them to a certain extent. However, some of the features within the Intel Graphics Command Center application that are specific to Intel graphics adapters may not work on a DisplayLink-attached display.

The DisplayLink driver does not support color calibration functionality of any kind. Most monitors have built-in controls that can be used to adjust the characteristics of the display, though we realize this approach may not be ideal in all cases. For environments that necessitate near-perfect color reproduction and display calibration capabilities via software, a dedicated graphics card is recommended.

Touchscreens that do not require drivers and use the host’s operating system’s built-in USB Human Interface drivers (HID) to record touch inputs can be made to work with our products, however Plugable does not provide support for doing so due the complexity of multi-monitor touch screen setups.

No, the DisplayLink device's presence on your system will not preclude the use of any of your system’s built-in video outputs.

The use of Powerline-based network adapters in conjunction with the Ethernet port within our DisplayLink-based docking stations or video adapters is not supported.

Windows does not have the ability to adjust the brightness of a display connected using DisplayLink technology. We recommend making use of the display’s internal on-screen menu options in order to adjust the display's brightness.

No, Plugable does not recommend or support using our DisplayLink-based docking stations with a traditional KVM switch. If you simply need to share the dock between two systems, the dock can be manually disconnected from the first system and then manually connected to the second system. 

For those using our USB 3.0 DisplayLink docking station products that would like a more permanent solution that does not require disconnecting the unit from the host system, our Plugable USB 3.0 Sharing Switch can be used as an alternative to share the dock between two systems (please keep in mind that the dock can only be used by one system at a time).

Wi-Fi Performance Issues

Any time a USB 3.0 device is connected to a laptop system, there is a potential that the USB 3.0 connection can generate interference that can affect the performance of the laptop's built-in Wi-Fi adapter.

This behavior is not specific to Plugable products, and Intel has published a white paper on the topic for those who are curious about the technical details. 

So now that we know that this can happen with any type of USB 3.0 connection, how do we solve the problem should it occur? Every person’s setup can be a little different so there will never be one definitive solution, but a few simple approaches can solve the problem in most cases:

• Option One—Move the device as far as away from the system as the USB cable will allow. This will try and ‘move’ the signals from both the USB connection and the Wi-Fi physically further apart. As a corollary to this, if the dock is located very close to the Wi-Fi router itself, placing more distance between the two can help.
• Option Two—Switch to a different USB port on the system, preferably one on the opposite side of the laptop. This employs the same approach as option one, in that physically separating the two signals (in this case the physical proximity of the USB connection and the internal Wi-Fi antennas within your system) can help. If your system has both USB 3.0 and USB 2.0 ports, try using the USB 2.0 port first.
• Option Three—Use a USB 2.0 cable, like one used connect to a USB printer, instead of a USB 3.0 cable. All USB 3.0 devices should be backward compatible with a USB 2.0 cable, and when a device is connected at USB 2.0 speeds there is no possibility for the interference.
• Option Four—Switch to using a 5GHz Wi-Fi connection. As the name implies, there are two common sets of frequencies used by most Wi-Fi networks (2.4GHz and 5GHz). If both your wireless router and the wireless network adapter in your system support a 5GHz connection (they both need to, one is not enough), connecting to your Wi-Fi in that manner will prevent the interference from happening due to the two very different frequencies in use.
• Option Five—If using a 5GHz connection is not possible, changing the ‘channel’ of a 2.4 GHz connection can help. Within the 2.4GHz band used for Wi-Fi, there are eleven different channels each using a slightly different frequency. The three most commonly used ones in the United States are channel 1, 6 and 11. Using the manual for your wireless router as a guide, switching channels can potentially help. Ideally you would want to switch the channel to the opposite end of the spectrum for the best results, for example if you are on channel one already try switching to channel eleven or vice-versa

Wireless Mouse or Wireless Keyboard Performance Issues (Radio Frequency Interference)

While the items listed above can help with Wi-Fi interference, there is another type of interference that can sometimes cause problems with wireless keyboards and wireless mice which we refer to as Radio Frequency (RF) interference. 

To expand further, the USB wireless receiver 'dongles' used by many wireless keyboards and wireless mice operate within the same 2.4GHz radio frequency range as many Wi-Fi adapters. 

If a USB 3.0 connection is generating interference, this can affect the behavior of a wireless keyboard or wireless mouse. This behavior typically manifests as inconsistent mouse movement and/or inconsistent or sporadic keystroke registration.

In general there are two methods to mitigate this behavior should it occur:

• RF Option One—Reconnect the USB wireless receiver 'dongle' to one of the USB Docking Station's USB 2.0 ports (if the dock has USB 2.0 ports), furthest away from the USB 3.0 host connection cable. Moving the USB receiver to a USB 2.0 port typically mitigates this interference.
• RF Option Two—In rarer cases when moving the receiver is not enough or if the product in question does not have a USB 2.0 port, adding a short USB 2.0 extension cable can also help mitigate the behavior. In many cases wireless mice or keyboards include such a cable for this very reason, but if one is not available our USB2-2PORT is a good alternative solution.

Our DisplayLink-based products are supported with macOS albeit with some potential limitations.

As of this writing, there are two different versions of the macOS driver that have been released by DisplayLink (the separate company that makes the primary chip within our DisplayLink-based products, and who also develops the software driver).

A ‘legacy’ version which uses a kernel extension in order to provide its functionality, and a newer ‘DisplayLink Manager Graphics Connectivity’ App which utilizes a new architecture that does not rely on a kernel extension to provide its functionality.

The choice of which driver to use is ultimately determined by one’s OS version and individual specific requirements, since each version offers different capabilities and operating system compatibility. We have provided a comparison table below that highlights their differences in an effort to help our customers make an informed decision.

*** Display rotation on Macs with an Apple CPU is accomplished within the DisplayLink Manager Application. It is NOT accomplished via the 'Displays' System Preferences application. More information on this feature is available here --> Link

**** There is a 3rd-party application called 'f.lux' that allows the adjustment of a display's color according to the time of day. This functionality is in 'beta' status, and must be enabled within the DisplayLink Manager Application in order to function. This functionality is supported with devices based on the DisplayLink DL-3xxx chipset, DL-5xxx chipset, and DL-6xxx chipset.  However, it is important to note that on DL-6xxx chipsets this functionality is limited to DisplayPort video outputs only. It is NOT supported on HDMI video outputs via DL-6xxx chipsets.

5. Select “Launch automatically after logging-in” for the software to start automatically every time you log-in.

6. Screen Recording

NOTE: From macOS Catalina 10.15, the operating system requires the user to permit "Screen Recording" in order for DisplayLink based devices (like Plugable UD-3900) to work properly. The message is generated by the OS and the screen is not actually being recorded by DisplayLink. Approving it enables the DisplayLink driver to access the pixels it needs to render a mirrored or extended screen and send the pixels over USB from your computer to the DisplayLink display. DisplayLink Manager does not store or record any screen content.

a. If you enabled notifications in step 3 you will see the below message if Screen Recording is switched off

b. This message will also show in the DisplayLink Manager app window and there will be an exclamation mark ‘!’ next to the DisplayLink Manager icon.

Within the ‘Home’ tab of the DisplayLink Manager Application, there are a few different items listed.  The items listed will vary depending upon which version of the DisplayLink Manager Application that is installed, and the following list describes the features present in DisplayLink Manager version 1.7.1.  

Login Screen Extension

By default, the ‘Login screen extension status:’ section will display, “Available to download and Install”

When an Apple Mac system is first powered on and reaches the login prompt, 3rd-party applications (such as the DisplayLink Manager application) are not yet running.  As a result, DisplayLink-connected displays will not function. 

Downloading and installing the Login screen extension (available by clicking on the ‘download’ link within DisplayLink Manager) will allow the DisplayLink-connected displays to function prior to logging in.  

This is of course an optional feature, and is not required to use DisplayLink devices.  However, this option is useful in certain situations, such as when only DisplayLink-connected displays are connected to the host Mac. 

Automatic startup

As the name suggests, placing a checkmark next to the ‘Launch automatically after login’ option allows the DisplayLink Application to start automatically each time the system is powered on. We recommend checking this option in the interest of efficiency. 

Apple Watch unlock

As the name suggests, placing a checkmark next to the ‘Use Apple Watch to unlock on the login screen’ will allow you to unlock your Mac using an Apple Watch while connected to a DisplayLink device. 

Apple has more information on this process here → https://support.apple.com/en-us/HT206995 

** Please note that this feature is not compatible with screensavers. To use Apple Watch unlock with your DisplayLink device, you must disable your screensaver. **

f.lux app support (Beta)

There is a 3rd-party application called 'f.lux' --> https://justgetflux.com/  that allows the adjustment of a display's color according to the time of day. If the f.lux application has been installed, placing a checkmark next to the 'f.lux app support (Beta)' option will enable f.lux to change the color of a DisplayLink connected display.

A few important notes about this feature:

A. This functionality is in 'beta' status, as the label suggests.  As a result, there may be cases where things may not work as expected when this option is enabled. 

B. This functionality is supported with devices based on the DisplayLink DL-3xxx chipset, DL-5xxx chipset, and DL-6xxx chipset.  However, it is important to note that on DL-6xxx chipsets this functionality is limited to DisplayPort video outputs only. It is NOT supported on HDMI video outputs via DL-6xxx chipsets.

System sleep in display-closed mode

Mac laptops running macOS 12 Monterey or newer can be used in one of two ways when used in conjunction with a DisplayLink-based product. 

The first way is with the laptop lid open, with the laptop's built-in internal display enabled.  

The second way is with the laptop lid closed, with the laptop's built-in internal display disabled.  This is known as closed display mode or 'clamshell' mode. 

In order to enter closed display mode while connected to a DisplayLink-based product, the host Mac must have an external power source connected and an external keyboard and mouse connected. 

Placing a checkmark next to 'Power save all displays and sleep in clamshell' changes this behavior, in that closing the laptop lid will cause the host Mac to go to sleep. 

This feature is of course optional, and its use is a matter of personal preference.  

Display rotation and toggle

The functionality presented within this section of the DisplayLink Manager Application will vary depending upon which type of processor is within the host Mac.

Macs with an Intel processor

When DisplayLink devices are used in conjunction with Apple Mac systems that have an Intel processor, a list of all the DisplayLink-connected displays will appear within this section. 

The individual displays can be turned on or off as desired by clicking on the toggle switch next to each display's name. You can differentiate between each display by hovering the mouse pointer over each display name.  When doing so, a red identification box will appear within the selected display.

You can rotate the orientation of the DisplayLink-connected displays within the ‘Displays’ macOS System Preferences application.

Macs with an Apple M1 or M2 processor

When DisplayLink devices are used in conjunction with Apple Mac systems that have an Apple M1 or M2 processor, display rotation must be done from within the DisplayLink Manager Application and the host Mac must be running macOS 12 Monterey or later (display rotation is not available on M1 Macs running macOS 11 Big Sur). 

Each DisplayLink-connected display attached to the M1 or M2 system will be listed next to the ‘Display rotation’ area. Click on the drop-down selection box and select the appropriate degree of rotation. 

If multiple displays are present, you can differentiate between each display by hovering the mouse pointer over each display name.  When doing so, a red identification box will appear within the selected display.

Synaptics (the creators of DisplayLink technology) have more information on this feature here --> Link

In addition to the rotation aspect described above, the individual displays can be turned on or off as desired by clicking on the toggle switch next to each display's name.  As mentioned above, you can differentiate between each display by hovering the mouse pointer over each display name.  When doing so, a red identification box will appear within the selected display.

After updating to macOS 13, DisplayLink controlled external displays may no longer be working, this can occur with older versions of the DisplayLink Manager App installed on the computer, or if the macOS "Screen Sharing" settings have been reset.  The most reliable way to resolve this is to fully remove and reinstall the DisplayLink Manager App using the latest released version compatible with macOS 13 Ventura.

Remove and reinstall DisplayLink Manager App

1. Disconnect the dock from the system and please remove the power cable from the dock so it turns off completely (this is important so the unit resets). Please keep it disconnected until the last step.
2. Restart the computer ( Apple Menu > Restart )
3. Log into the computer and open the Finder > Go > Applications window
4. Double-click on the "DisplayLink Software Uninstaller" and follow the onscreen steps to remove the DisplayLink software
   1. If you encounter an error where the DisplayLink Manager App is running and you cannot close it please continue with 4B-4E below:
   2. Open the Finder > Go > Utilities > Activity Monitor
   3. Scroll down and select the "DisplayLinkUserAgent" from the list
   4. Click on the button at the top of the screen to "Stop" the application ( an octagon with an 'x' in the center )
   5. Retry step #3, if it still will not uninstall: open the Applications window, then click and drag the DisplayLink Manager App to the trash
5. When the software removal has completed please restart the computer ( Apple Menu > Restart )
6. Log back into the computer and install the latest DisplayLink software following these detailed instructions ( https://kb.plugable.com/1595423 )
7. Restart the computer when completed ( Apple Menu > Restart )
8. Reattach the power cable to the dock first. Once the dock is powered on, reconnect it to your system and check for the displays and USB devices to be detected

Many steaming video services require HDCP (High-bandwidth Digital Content Protection) enabled devices from the video source all the way to the display.  We speak more to HDCP here (https://kb.plugable.com/en_US/docking-stations-and-video/381072-video-hdcp). The DisplayLink hardware and software used to enable multiple external displays with our docking stations requires enabling the "Screen Recording" permissions in macOS, this disables HDCP video playback system-wide.

The DisplayLink software isn't exactly recording the screen, as the setting's name suggests, instead it is rendering the external display and transmitting it as USB data to the docking station, however Apple does not have a security category for USB external displays and "Screen Recording" is the best fit.

This disables HDCP system-wide because there is no differentiation within macOS for the DisplayLink controlled external displays from the displays controlled by the internal graphics controller: the built-in LCD, or directly connected display(s).

Working around HDCP limitations:

Apple's Intel based Macs with Thunderbolt 3 can support up to two displays connected through a Thunderbolt 3 docking station, these displays do not require installing the DisplayLink Manager App and can be used for video playback.

• 13-inch MacBook Air and MacBook Pro systems with Intel processors can support up to two external displays in this configuration.
• 15-inch/16-inch MacBook Pro systems with Intel processors and AMD graphics can support up to four external displays ( two on the docking station, and two more either connected directly to the computer or with a second Thunderbolt 3 docking station ).
• iMac and Mac Mini systems with Thunderbolt 3 and Intel processors can support up to three total displays ( one built-in/HDMI, and two with the docking station ).

Apple Silicon (M1 and M2) based Macs support varying numbers of displays:

• M1 and M2 13-inch MacBook Pro and MacBook Air systems, and the M1 iMac can only support a single external display with a Thunderbolt 3 or USB-C single display docking station with HDCP video compatibility.  For supporting more than one external display, DisplayLink or similar technology is required and will prevent HDCP video playback.
• M1 Mac Mini can support up to two displays, one connected to the HDMI output, the second connected to a Thunderbolt 3 or USB-C single display docking station with HDCP protected video playback enabled.  For supporting more than two external displays, DisplayLink or similar technology is required and will prevent HDCP video playback.
• M1 MacBook Pro 14-inch, or 16-inch with M1 Pro or M1 Max processors can support up to two external displays with a Thunderbolt 3 docking station, or multiple displays using direct USB-C connections, with these displays supporting HDCP video playback.

Please feel free to contact our support team at 'support@plugable.com' if you have any additional questions regarding HDCP compatibility, video playback, or multiple display support with your computer.

Common Causes

For Windows 10 and Windows 11 host computers, the most common cause is out of date graphics hardware drivers, or DisplayLink graphics software. Most Windows computers receive updated graphics drivers through Windows Update, however this often provides significantly out of date drivers, some dating back over two years, that may not be fully compatible with the installed version of Windows.

Graphics controller manufacturers provide the latest graphics drivers from their websites, these generally provide better performance, security, and compatibility than the out of date drivers from Windows Update or the system manufacturer's website.

The exception to the above is for systems with two or more active graphics controllers, for example a laptop computer may have an Intel Graphics Controller built into the processor, as well as an NVIDIA Graphics Controller with the operating system automatically switching between the two graphics controllers based on the applications running on the computer. These systems require a delicate balance between the graphics drivers for the primary and secondary graphics controllers, Windows version, and the DisplayLink software.

Determining your computer's graphics controller

Most hardware manufacturer's provide a single unified driver package for a wide range of graphics controllers, however it is best practice to ensure the drivers are compatible with the hardware. We can look up the graphics controller through Windows "msinfo32.exe" System Information application:

1. Open the Start Menu
2. Search for "msinfo32" then select the b est match "System Information App"
3. Note the "Processor" model details in the "System Summary" section, as some graphics drivers are referenced by the processor model
4. In the left pane, expand the section "System Summary > Components" and then select "Display"
5. In the right pane note the value for the item "Name", this will be the graphics controller for discrete graphics controller

Updating the Graphics Drivers to the latest version

For systems with Intel Graphics Controllers

Intel uses a unified driver installer for all of their processor graphics from the 6th Generation CPU onward (Intel i-series 6000 and newer).

1. Download the latest Intel Graphics Drivers from Intel's website here by selecting the blue "Download" button for the graphics driver ".exe" file (normally the top option). Save this file to the Downloads directory or Desktop
   
2. Save and close any open applications, unplug the docking station or graphics adapter from the computer, and connect the original power supply (for laptop/notebook computers)
3. Right-click on the Intel Graphics Driver package and select "Run as Administrator" from the drop down menu
4. Allow the installer in the Windows User Account Control pop-up
5. Follow the on screen instructions to install the latest graphics drivers
   -If there is an error message while updating the graphics drivers with regard to an "OEM" or "System Manufacturer's" driver or that these drivers are incompatible with the computer, Intel provides additional details and steps to remove OEM or legacy drivers from the system here
6. When complete, restart the computer before reconnecting the docking station or graphics adapter

For systems with NVIDIA Graphics Controllers

NVIDIA also uses a unified driver installer for most of their discrete desktop and notebook graphics controllers.

1. Locate and download the latest NVIDIA graphics driver from here using the graphics controller model details from msinfo32, save the file to the Downloads directory or Desktop
   
2. Save and close any open applications, unplug the docking station or graphics adapter from the computer, and connect the original power supply (for laptop/notebook computers)
3. Right-click on the NVIDIA Graphics Driver package and select "Run as Administrator" from the drop down menu
4. Allow the installer in the Windows User Account Control pop-up
5. Follow the on screen instructions to install the latest graphics driver, select the "Custom" or "Advanced" installation option if available, at the custom installation screen select the option to "Perform a clean installation"
6. When complete, restart the computer before reconnecting the docking station or graphics adapter

For systems with AMD Graphics Controllers

AMD also uses a unified driver installer for most of their discrete desktop and notebook graphics controllers.

1. Locate and download the latest AMD graphics driver from here either by selecting the graphics controller or AMD processor with integrated graphics from the lists, or by searching for the specific controller or CPU from msinfo32 in the "Search All Products" drop down menu
   
2. Save and close any open applications, unplug the docking station or graphics adapter from the computer, and connect the original power supply (for laptop/notebook computers)
3. Right-click on the AMD Graphics Driver package and select "Run as Administrator" from the drop down menu
4. Allow the installer in the Windows User Account Control pop-up
5. Follow the on screen instructions to install the latest graphics driver
6. When complete, restart the computer before reconnecting the docking station or graphics adapter

With macOS 13.3.1 update we have started to see reports of the macOS window server crashing on Apple Silicon based computers (M1/M2 processors).  Either at login if a DisplayLink based docking station or USB graphics adapter is connected to the computer, when connecting the DisplayLink controlled display to the computer after login, or when launching the DisplayLink Manager App with the external display connected to the computer.

We have seen this behavior when the macOS's display persistence files have become corrupt, or include incompatible display configurations or settings.  The fix was to manually remove two display persistence ".plist" files, however now the DisplayLink Support Tool for macOS has an option to reset the display persistence to quickly resolve this behavior, the process is detailed below:

1. Unplug the DisplayLink controlled external display from the computer and log into the desktop
2. Download the DisplayLink Support Tool for macOS
3. Select the "DisplayLink Support Tool for macOS6.3.163-EXE.zip" from the downloads to extract the "DisplayLink Information.app" to the Downloads directory, a Finder window should open showing the extracted file
   
4. Double-click on the "DisplayLink Information.app" from the Downloads folder to start the tool
   
5. This will open a window for the DisplayLink Information tool, however we can ignore this for now. From the macOS top bar, next to "DisplayLink Information" select "Advanced" then "Reset screen layout"
   
6. You will be prompted for the account password to proceed, enter your password, then click the "OK" button
   
7. Next you will be prompted to reboot the computer, save and close any open applications then click on the "Reboot" button to proceed
   
8. After rebooting the computer, log into the desktop and reconnect the external display(s), you may need to rearrange the external displays through the Apple Menu > System Settings > Displays > Arrange settings panel

If you are experiencing this behavior, with the system logging in and back out, or logging out when connecting the DisplayLink based docking station or graphics adapter and the above does not help, please contact our support team via email at 'support@plugable.com' and we will be happy to help!

Most Windows notebook computers power management settings will default to putting the computer to sleep with the lid closed, regardless of any external displays, keyboard, or mouse connected to the computer. If this is happening but you would prefer the system to remain active with the lid closed utilizing the external display or displays, these settings can be changed by performing the following:

For Windows 10:

1. Start by right-clicking on the Start button and select Power Options from the menu.
2. From the right side of the Power Options settings page, select the blue link for Additional power settings

   

3. From the choices present on the left-hand side of the Power Options window, please click on Choose what closing the lid does
4. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

5. Click the Save Changes button and restart the system (making sure that the laptop’s power adapter is also connected) and test the behavior again.

For Windows 11:

1. Start by right-clicking on the Start button and select Power Options from the menu.

   

2. In the upper left corner of the settings window, in the search box, type "lid" then select Change what closing the lid does from the search results

   

3. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

4. Click the Save Changes button to apply the new settings.

Closing the lid should no longer put the computer into sleep mode when an external display and power source is connected, instead one of the external displays should now become the Primary display with the desktop icons instead of the laptop's built-in display.

The lid may still need to be opened to perform the following tasks:

• To power on the computer from a fully powered off state
• To log into the computer if logged out or if the computer is restarted with the lid closed
• To wake the computer from a deep sleep state ( hibernation, or Windows hybrid sleep states )

Unsure which version of macOS you have installed? Click on the ‘Apple’ icon in the menu bar on your desktop and select ‘About this Mac’. A new window will open and display the system’s macOS version.

If your Windows laptop will not boot properly when a docking station is connected to the laptop, most often the cause is an external device connected to the docking station (for example an external USB storage drive) as opposed to the dock itself. 

If you are affected by this condition, please follow these steps in order to isolate the behavior further:

1. Disconnect all USB devices from the docking station and put them aside for the moment.
2. Disconnect any displays connected to the dock's video outputs.
3. Disconnect any audio devices connected to the dock's audio ports (if present).
4. Disconnect the Ethernet network cable from the dock's Ethernet port (if present).
5. The only remaining connections should be the dock's power adapter cable and the USB cable used to connect it to the laptop. No other external devices should be connected to the dock.
6. While in this state, reboot the laptop to test the behavior.
7. Assuming the laptop boots as expected, please reconnect each device back to the dock one at a time and reboot after each one to test the behavior again. Please reconnect the displays first, then the audio devices, then the Ethernet cable. Please reconnect any USB devices to the dock last, again rebooting after each one is added to test the behavior.

In our experience helping others, the most common cause of this behavior is an external USB storage drive connected to one of the dock's USB ports.  In some cases, a laptop may try to boot from an external storage drive by mistake as opposed to the laptop's built-in storage drive.  Since most external USB storage drives are not 'bootable', this can interrupt the boot process. 

If this behavior occurs, the most common way to mitigate the behavior is to access the laptop's System BIOS (also known as UEFI firmware) to change the 'boot order' settings to ensure that the laptop's internal storage drive is the first boot option.  Doing so helps ensure that the laptop will not try to boot from an external USB storage device. 

Every laptop system is different, so the best resource for accessing the System BIOS and changing the settings is the manual for the laptop provided by the laptop manufacturer.   

Docking stations based on DisplayLink USB video technology are in essence a 'virtual' graphics adapter that relies on the host laptop's CPU and internal physical graphics processing unit (aka as GPU) to generate the information shown on the dock-attached displays.

In rare instances, Windows applications that use a technology known as OpenGL to draw the image shown on the display will attempt to direct OpenGL related tasks to the DisplayLink-based docking station's virtual graphics adapter, and not to the 'real'/'physical' GPU within the laptop.  

Since the dock is not a physical GPU that supports OpenGL, this can sometimes cause applications that make use of OpenGL (such as Google Earth or AutoCAD) to not work as expected or result in various types of error messages. 

The true root cause of this behavior can vary, and ultimately lies outside of the docking station or its associated DisplayLink driver. In some cases the root cause lies within the Windows driver for the host system's physical GPU and in rarer cases within the Windows operating system itself.  

In some cases updating either the driver for the system's internal GPU or updating Windows itself (when Microsoft provides such updates) can help, however that is unfortunately not always the case.

If updating those components does not help, in most cases there are two possible workarounds. 

The first is to configure Windows to have the ‘Main’ display set to a display directly connected to the host system's built-in internal GPU, whether that is an internal laptop display or another external display connected to one of the system's built-in video outputs (a quick guide to doing so is here -> https://youtu.be/7nnKztRZXsw). 

If the first option does not prove a suitable workaround, the second option is to boot the system without the dock connected, launching the affected application, and then connecting the dock may also help.

When upgrading the DisplayLink Manager Graphics Connectivity App to new version within a macOS system, the update process will cause the older version of the App to quit. As a result, any monitors connected to a DisplayLink-based USB video adapter or docking station will stop working.

The solution is to manually start the new version of the DisplayLink Manager Graphics Connectivity App by double-clicking on the App's icon within the macOS 'Applications' folder within the macOS Finder. This will restart the DisplayLink Manager Graphics Connectivity App, which in turn will enable any monitors connected to a DisplayLink-based USB video adapter or docking station to start working again. 

Some users have reported after macOS Big Sur 11.1 and newer that their USB-C Triple Display Docking Stations may not be correctly detected by Apple’s MacBook Air, MacBook Pro, Mac Mini, iMac, and Mac Studio computers with Apple Silicon processors after being restarted, when powered on after being turned off, or after being in sleep mode and then woken up. Older Intel based Macs are unaffected.

This issue affects the UD-ULTCDL (original version), UD-ULTC4K (original version), and UD-3900PDZ docking stations along with any connected USB 2.0 and 3.0 devices, including the two DisplayLink based video outputs, Ethernet, and audio controlled by the DisplayLink USB Graphics chipset. The primary USB-C DisplayPort Alternate Mode based video output and connected display should remain functional after reboot. Charging should also be unaffected.

For most users simply unplugging the docking station from the computer, waiting 10-15 seconds, then reconnecting the docking station will restore the functionality, if this does not help please try these additional steps to fully reset the docking station and computer: 

1. Unplug the dock from the Mac and unplug power from the dock. Please leave the dock disconnected until the final step.
2. Fully shutdown the Mac. (On your Mac, click the "Apple" menu and select "Shut Down")
3. After the Mac has shutdown, wait for 60-90 seconds, then turn the Mac back on.
4. After logging back in, wait for an additional 30-60 seconds, then plug power back into the dock first and plug the dock into the Mac next (using the provided USB-C to USB-C cable the dock shipped with) and see if the behavior has improved.

We are hopeful this issue may be resolved by a future update to macOS but do not have a timeline for such a resolution. As of macOS 11.6.8 Big Sur and macOS 12.6.1 Monterey this issue is still present.

If these initial troubleshooting steps do not help, please contact us at support@plugable.com and we'll be happy to assist you.

Plugable has received reports of Notifications not working as expected when a DisplayLink-based product (such as our UD-3900 or UD-6950Z docking stations) is connected to a Mac running macOS 12 Monterey. 

The cause of this behavior is still being investigated, however in our experience making a small change within the ‘Notifications & Focus’ preference settings can help.

For macOS 12 Montery, please follow these steps:

1. Click on the ‘System Preferences’ icon (looks like a gear) in the macOS Dock at the bottom of your screen
2. Click on the ‘Notifications and Focus’ application
3. At the bottom of the ‘Notifications and Focus’ application window, click to place a checkmark in the ‘When mirroring or sharing the display’ option under the ‘Allow notifications’ section.  An example screenshot with this option highlighted is included below:

For macOS 13 Ventura, please follow these steps:

1. From Finder, click on the Apple Menu then select System Settings
2. On the left side select "Notifications"
3. On the right side select the option to "Allow notification s when mirroring or sharing the display"
4. Under Application Notifications select "DisplayLink Manager"
5. Toggle on the "Allow notifications" option at the top

UPDATE 5/24/2022 - To the best of Plugable's knowledge, the unexpected behavior described below has been resolved by the macOS 12.4 update.  While the issue has been resolved, the information below has been retained for historical reference. 

Plugable’s products based on DisplayLink technology have the ability to send an audio signal out via their 3.5mm analog audio jacks or via their HDMI or DisplayPort video output ports (which can also carry an audio signal). 

Examples of Plugable products based on DisplayLink technology are the UD-3900, UD-6950Z, or USBC-6950U. Any Plugable product based on DisplayLink technology will have a 'DisplayLink' logo printed somewhere on the product. If a Plugable product does not have this logo, then it does not use DisplayLink technology.  

In some cases, when DisplayLink-based products are used with a Mac running macOS 12 Monterey the audio signal may not be heard when switching to the DisplayLink-based device.  

This behavior appears to be tied to the order in which an audio output device is selected and used within macOS. For reference, the macOS driver used for the audio device within any DisplayLink-based product is provided by Apple and built-in to macOS.   

To expand further, consider the following two examples:

‘Working’ example

1. A Mac system is powered on with a DisplayLink device already connected. 
2. The DisplayLink device is set to the default audio output device within the ‘Sound’ macOS System Preferences application. 
3. An application plays a file that contains audio. 
4. The audio signal is heard properly via the DisplayLink device.

‘Not working’ example

1. A Mac system is powered on without a DisplayLink device connected
2. The Mac’s built-in audio output device is set as the default audio output device within the ‘Sound’ macOS System Preferences application. 
3. An application plays a file that contains audio. 
4. The audio signal is heard properly via the Mac’s built-in audio output device.
5. A DisplayLink device is connected to the Mac
6. The default audio output device within the ‘Sound’ macOS System Preferences application is changed to the DisplayLink device.
7. An application plays a file that contains audio. 
8. An audio signal is NOT heard via the DisplayLink device. 

At this time, there are three potential workarounds for this behavior:

• Restart the Mac
• Completely close the application that is affected by the behavior, and then restart the application
• Execute this command from within the macOS Terminal application (without the quotes) -->  'sudo killall coreaudiod'

Yes! As long as the software drivers for both Silicon Motion and DisplayLink-based products are installed on the same computer these two USB graphics solutions can work together and be used at the same time.

Some users have reported network issues when using the Ethernet port on our UD-6950PDZ USB-C Triple 4K Docking Station.  Either the computer is unable to connect to the local network or network performance slower than expected.  This issue affects a small number of the initial production run of these docking stations and we have addressed and resolved the issue with the second production run.

This issues may affect docking stations with serial numbers begging with: 2728, 3248, 3249, 3250, 3364, docking stations with serial numbers above 3364 are not affected.

For users who experience network connectivity problems we recommend contacting our support team via email at 'support@plugable.com' and we will be happy to help confirm if your docking station is affected and get the replacement process started, or if the docking station is not affected by this fault we can then help to troubleshoot and resolve the networking problem.

Detailed Problem Description

We have had two distinct behaviors reported:

1. Some users have been assigned IP Addresses in the 169.254.0.0/16 network address range or have not received full DHCP address assignment

2. Some users have received DHCP assigned IP Addresses but have limited or no internet connectivity or poor network performance

Cause

This behavior is caused by lower than expected voltage reaching the Ethernet PHY chipset, this chipset converts and transmits Ethernet data to the Ethernet port.  In the low voltage state receiving and transmitting data may fail causing either reduced network performance or failure to establish a network connection altogether.

Affected Docking Stations

UD-6950PDZ USB-C Triple 4K Docking Stations with DisplayPort and HDMI with serial numbers begging with: 2728, 3248, 3249, 3250, 3364 may be affected by this behavior.  Docking Stations with serial numbers greater than 3364 are not affected.

Mitigation

Please contact our support team at 'support@plugable.com' and include in the body of your email:

1) The Amazon Order ID ( available from amazon.com/orders ) for the original purchase of the docking station

2) The serial number from the bottom of the docking station in the format '####A#####'

A description of the behavior you are seeing and we can proceed from here.

At this time we are recommending affected users unplug the Ethernet cable from the docking station and rely on WiFi if available, use a separate USB Ethernet Adapter, either connected to the docking station or computer, or for computers with built-in Ethernet ports the cable may be connected directly to the computer. This should ensure a reliable network connection while we work with you to resolve this issue.

Resolution

We have re-designed the Ethernet logical to physical component of the docking station to ensure stable Ethernet connectivity and are replacing faulty docking stations with the updated model.  New docking station sold through Amazon since July 2022 all have the updated Ethernet configuration and are not affected by this behavior.

If you are experiencing network issues with the UD-6950PDZ docking station, please contact our support team at 'support@plugable.com' and include the information in the Mitigation section above.

DisplayLink has a 'Corporate Deployment' section within their online knowledge base that speaks to all of the corporate deployment options available for the software --> https://support.displaylink.com/knowledgebase/topics/92322-corporate-deployment  

Plugable does not support any of the 'Corporate' installation methods of the DisplayLink software.  

Should you require assistance with a corporate deployment method of the DisplayLink software, we would suggest contacting DisplayLink directly for assistance --> https://support.displaylink.com/knowledgebase 

Plugable’s USB video adapters or USB docking stations based on DisplayLink technology do not support the playback of copy-protected or encrypted video content, and we do our best to call this out in our product listings. 

Examples of this type of video content are:

• Video content that is protected by High-bandwidth Digital Content Protection (also known as HDCP), for example Blu-ray discs
• Copy-protected video content provided by various online streaming services, for example Netflix, Hulu, Amazon Prime Video, iTunes, Disney+, YouTubeTV, etc. 

As a result, copy-protected video content may not display an image on-screen while using a DisplayLink-based product. 

In some cases (such as when using a streaming service) the copy-protected video content may display an image on-screen, however the resolution of the image may be lower than expected. 

If your package is missing one or more of the items that should be included with your Plugable dock (included items are listed on a chart on the side of the box), start by double checking if the part is still in the packaging. Pieces can occasionally get stuck in the corners under the main insert in the box.

If you are still unable to locate the piece, please contact support@plugable.com with the following information:

1.  Amazon Order ID (or other proof of purchase) associated with your Plugable device.

2. A description of the parts that are missing from your order.

3. Your preferred shipping address (and a phone number associated with that address).

4. The serial number of your Plugable Dock.

Plugable docks do not officially support monitors with a 120Hz or 144Hz refresh rate (only 30Hz or 60Hz depending on the product). 

Monitors with refresh rates higher then 60Hz should be connected to a video output directly on the computer to ensure the display is powered by the system's native GPU.

Unfortunately Plugable products do not support the Apple SuperDrive.

The Apple SuperDrive has stringent power requirements that can only be met by directly connecting the SuperDrive to your host laptop. As a result at this time Apple recommends only using their USB-C adapter cables. You can find more information on that here -→ How to connect the Apple USB SuperDrive

If you have purchased a Plugable product to use with your Apple SuperDrive, and would like some additional assistance please do not hesitate to reach out. You can do so by emailing support@plugable.com, or going to Plugable.com/Support.

Please Note

The below guide is an advanced troubleshooting step, and we do not recommend doing so unless you are comfortable manually altering files on your Apple product running macOS. You may not be able to perform the below troubleshooting step if you are unable to execute administrative credentials on your laptop. Please reach out to our support first if you do not wish to attempt the below instructions. You can do so at Plugable.com/Support

I am still unable to get my Ethernet connection working on my Mac

If this is the case please reach out to our support team. When you do please include a diagnostic log gathered using our PlugDebug tool (instructions are provided on the PlugDebug page). If you are not able to gather the PlugDebug diagnostics do not worry we are still here to help! Please reach out to our support team at support@plugable.com or Plugable.com/Support with a detailed description of your problem, and the model of Plugable product you are using.

Plugable’s DisplayLink-based products are supported with ChromeOS (the operating system used in Chromebook laptops), however there are some potential limitations.

In brief:

1. Plugable recommends using our DisplayLink-based products with Chromebooks that have an Intel central processing unit (CPU) or an AMD CPU.  Chromebooks with ARM CPUs are not recommended due to ARM CPU performance limitations.

2. Most Chromebooks meet the minimum hardware specifications we recommend for use with products based on the DL-3900 chipset.

The DL-6950 chipset has higher recommended hardware specifications which may not be met by some Chromebooks, which in turn may result in lower than expected performance.  

As of this writing, Plugable makes products based on the DisplayLink DL-3900 (https://www.synaptics.com/products/displaylink-graphics/integrated-chipsets/dl-3000)  and DL-6950 chipsets (https://www.synaptics.com/products/displaylink-graphics/integrated-chipsets/dl-6000).  You can determine which DisplayLink chipset is in use within a Plugable product by its model name. For example, a ‘UD-3900’ docking station uses the DL-3900 chipset and a ‘UD-6950Z’ docking station uses the DL-6950 chipset.

3. For best performance, Plugable recommends using our DisplayLink-based products with Chromebooks that were released in the year 2020 or later. 

4. Plugable recommends that a Chromebook have ChromeOS version 100 or later installed. Earlier versions of ChromeOS are not officially supported. Only the 'Stable' release channel of ChromeOS is supported. The 'Beta', 'Dev', or 'Canary' release channels of ChromeOS are not supported. 

5. In some cases, the wired Ethernet network adapter within a Plugable DisplayLink-based product may perform at a lower than expected level of performance when used with a Chromebook as compared to when the same device is used with a Windows or Mac computer.  

As a result, the Ethernet adapter may not support Gigabit Ethernet speed. This is due to a limitation of the Ethernet network driver built-in to ChromeOS, it is not a limitation of Plugable’s DisplayLink-based products. 

6. Google exercises complete control over ChromeOS. As a result of this control, there can be cases where a ChromeOS update could cause unexpected behavior of a Plugable DisplayLink-based device.  

It is not possible for a 3rd-party to install driver updates or apply fixes to ChromeOS. All driver updates or fixes are provided by Google as Google publishes updates to ChromeOS.  

7.. Plugable offers a diagnostic utility called PlugDebug → https://plugable.com/pages/plugdebug which helps simplify the process of assisting our customers using Windows, macOS, or Linux. 

Unfortunately due to the control Google exercises over ChromeOS, it is not possible to use a diagnostic tool like PlugDebug with a Chromebook.  

More detail:

To expand further on some of the items listed above…

Plugable products based on DisplayLink USB video technology (https://www.synaptics.com/products/displaylink-graphics) are in essence ‘virtual’ graphics processing units that rely on the host computer’s central processing unit (CPU) and physical graphics processing unit (GPU) in order to generate the image shown on the DisplayLink-attached displays. 

Because ChromeOS is quite efficient, it does not generally require a powerful CPU in order to work well. As a result, many Chromebooks have lower powered CPUs as compared to their Windows and Mac counterparts. 

This is a boon in that Chromebooks can be made comparatively cheaper and have excellent battery life, however when it comes to using Plugable products based on DisplayLink technology some lower powered processors may not provide the same level of performance as compared to a system with a more powerful CPU and GPU. 

This drives our recommendation that for best performance, Chromebooks made in 2020 or later that have either Intel CPUs or AMD CPUs be used in conjunction with Plugable’s DisplayLink-based products. 

This symbiotic relationship is also what informs the potential performance differences between products based on the DL-3900 and DL-6950 chipset. 

Some Chromebooks are based on an ARM CPU, and speaking in general the ARM CPUs are not as powerful as an Intel CPU or AMD CPU.  As a result, we do not recommend using Plugable’s DisplayLink-based products with Chromebooks that have an ARM CPU.

If you are unsure which type of CPU your Chromebook has within it, you can consult the Chromebook manufacturer’s specifications.

If the manufacturer’s information does not help, Google maintains a list of all Chromebooks and the type of CPU they have here → https://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices/

Within Google’s list, the column ‘User ABI’ refers to the type of CPU, where ‘x86_64’ refers to an Intel or AMD CPU while ‘arm’ refers to an ARM CPU.

Further to this, a Chromebook should have ChromeOS version 100 or higher installed in order to be used with a Plugable DisplayLink-based product. Google has a guide for determining the ChromeOS version as well as updating ChromeOS here → https://support.google.com/chromebook/answer/177889

Modern operating systems support adjusting the color of the image shown within external displays in order to make the image more pleasing depending upon the time of the day.

In Windows 10 and Windows 11, this feature is known as ‘Night Light’ → https://support.microsoft.com/en-us/windows/set-your-display-for-night-time-in-windows-18fe903a-e0a1-8326-4c68-fd23d7aaf136

In ChromeOS, this feature is also known as ‘Night Light’ → https://support.google.com/chromebook/answer/9145848?hl=en

In macOS, this feature is known as ‘Night Shift’ → https://support.apple.com/en-us/HT207513

When using a DisplayLink-based product based on the DL-3xxx, DL-5xxx, or DL-6xxx chipsets, as of today the level of support for color adjustment is as follows:

In order to use one of our DisplayLink-based products with a Mac, the DisplayLink Manager Application must be installed. 

We have found that in most cases the initial installation of the application completes without any issues. 

With that said, there can be rare cases where the initial installation of the application may not complete successfully, and result in an ‘Unexpected Error’.

While each support case is unique, in our experience helping others we have found that there can be a few potential causes for this condition:

A. The end-user does not have the authority or permission in order to install software applications on the host computer. 

In some enterprise or corporate environments there are security restrictions in place that prevent the end-user of the Mac from installing software applications. 

If your Mac has been provided to you by your company or enterprise, please reach out to your organization’s IT support department in order to determine if you have both the necessary permission and authorization in order to install software on your Mac

B. The destination for the installation of the DisplayLink Manager Application software is not a valid location.

The DisplayLink Manager Application must be installed to the Mac’s built-in internal storage drive, and the drive must have the required amount of available storage space to accommodate the installation. 

The DisplayLink Manager Application should not be installed on an external storage drive, or to any type of cloud storage drive (such as Microsoft OneDrive, DropBox or Google Drive) mounted as a local physical storage volume.

In addition, the DisplayLink Manager Application installation process should not be executed while the installation file is located within any type of cloud storage drive (such as Microsoft OneDrive, DropBox or Google Drive) mounted as a local physical storage volume.  

C. macOS does not have permission to access the location of the DisplayLink Manager Application installation file.

The macOS ‘Installer’ application must have permission to access the location of the DisplayLink Manager Application installation file in order for the installation process to complete successfully. If this permission is not granted, then the installation process will not complete successfully. 

In our experience helping others, we have found that some of our customers using macOS 13 Ventura may encounter an error during the installation process if this permission has not been granted. 

To expand further and as an example, the first time you download an application to your Mac’s ‘Desktop’ folder and attempt to install the application macOS 13 Ventura will prompt you to grant permission to the macOS Installer application to access the ‘Desktop’ folder.  

If this permission is granted, then the application installation process should complete successfully.  If the permission is not granted, then the application installation will not complete successfully.   If the permission is not granted and you attempt the installation process a second time, macOS will NOT prompt you to grant permission because of the previous denial. 

The most straightforward way to ‘reset’ these permissions is as follows:

1. Click on the Apple Menu item at the top of your screen and select ‘System Settings’ from the menu that appears

2. In the list of items presented on the left-hand side of the ‘System Settings’ application window, click on the ‘Privacy & Security’ item.

3. Within the ‘Privacy & Security’ section, scroll down in the list and click on the ‘Files and Folders’ item.

4. Within the ‘Files and Folders’ section, there should be an entry for ‘Installer’.  Click on the ‘Installer’ entry in order to select it.  Once the item is selected, it should appear blue in color.

5. At the bottom of the list of items within the ‘Files and Folders’ section, there will be a small horizontal line that looks like a dash or a minus sign (-).  Click on the horizontal line, which will remove the ‘Installer’ entry from the list. 

*** Important note - please do not make any other changes in this location, other than what we describe above ***

6. Close the ‘Systems Settings’ application

7. Attempt the installation of the DisplayLink Manager Application again. 

To help provide more context, an animated example of this process is below:

We are often asked if it is okay to leave a notebook computer connected to one of our USB-C docking stations with Power Delivery for extended periods of time.  The short answer is yes, it is no different from leaving the laptop connected to the manufacturer's original USB-C power supply for the same time.  The long answer is yes for modern laptops, and maybe for older (1990s-early 2000s laptops) and involves going into the different battery technologies used in consumer electronics devices.

Another common question is if it is possible to use the docking station but to disable powering and charging the computer.  When a modern notebook computer runs on battery power it will often set the system to a reduced power state which may impact performance, or connected devices and we recommend always powering the computer when using a desktop docking station.  For all of our docking stations that provide power to the host computer this will not affect the lifespan of the computer's battery.

Modern Laptop Batteries: Lithium-Ion

Lithium-ion (li-ion) batteries are found in a wide range of consumer electronics from notebook computers and cell phones, to electric cars, power tools, and wearable electronics like wireless earbuds.  Li-ion offers fast charging, high-current discharging, fairly long service live compared to other rechargeable battery technologies and are relatively inexpensive.

The life-span of a rechargeable battery depends on many factors including age, temperature history, charging patterns, the chemical composition of the specific battery, and usage.  For example batteries stored at 100% charge will degrade faster than batteries stored at 50% charge, this is why most consumer electronics devices arrive from the manufacturer with between 25% to 75% charge.

Lithium-ion batteries are consumable components, however in most modern computers, cell phones, and tablets these are not user serviceable components.  To help maintain the battery all modern computers and most consumer electronics will include battery charge and protection circuits.  These can be fairly simple, charging up the battery at preset rates depending on the charge level to help maintain the battery life, or complex software controlled charging that monitors battery temperature, voltage and current draw to maintain the fastest charging while maintaining the battery longevity.

Modern notebook computers can be left connected to the original power cable or a docking station with charging capability for extended periods, and do not benefit from regular discharge/recharge cycles.  Our docking stations with charging capability rely on USB Type-C Power Delivery to power and charge compatible computers.  USB Type-C Power Delivery is a negotiated charging protocol between the host computer and the docking station or USB Type-C power supply, this allows the computer to draw only the power it requires, and even select the best voltage level for powering the computer.  In combination with a computer's built-in battery charging controller the computer is capable of maintaining the battery's optimal state even when left connected to a power source for an extended period of time.

Legacy Laptop Batteries: NiCad and NiMH

Older laptops, from the 1990s and some early 2000s, as well as some consumer electronics, and most rechargeable AA or AAA battery replacements use Nickel-Cadmium (NiCad) or Nickel-Metal Hydride (NiMH) batteries.  These batteries are slower to charge and discharge than li-ion batteries, and require very simple charge controllers, and in some cases can even be trickle-charged ( very low-current continuous charging ) if desired.

These batteries generally don't have smart charging controllers and to prolong the life of the battery required "training" or fully discharging and recharging the battery every so often.  Many laptop manufacturers recommended fully charging and discharging a new laptop 2-3 times to train the battery, this is not necessary with modern laptops.

Conclusion

Modern notebook batteries are managed by the computer's built-in battery charging circuit, and require little to no user intervention to maintain optimal battery health.  It does not harm the battery to leave the computer connected to an external power supply, so long as the computer is being used regularly.  If the computer is to be stored for a prolonged period then discharging the battery to between 50-75% can help to maintain the battery life.

Batteries are consumable components and degrade over time, however modern notebook computers can extend the battery life generally to meet or exceed the life of the computer's other electronic components.
