Troubleshooting

Lenovo Docking Station

The dock does not work after connected to my computer.

Ensure that:

You use the accompanying ac power adapter, power cord, and USB-C cable.
The dock is powered by its power adapter. The dock always needs an external power adapter for operation because it is not powered by the USB-C cable attached to your computer.
The dock driver is installed on your computer.
The USB-C connector on your computer works well.

The function of wireless keyboard or mouse (2.4 GHz) is interrupted. The mouse pointer lags or does not move. Some characters are lost when I input by the keyboard.

Connect the wireless device receiver to a USB 2.0 connector on the dock.

The mouse or keyboard cannot wake up my computer when connected to the Always On USB 3.1 connector Gen 2 on the dock.

Connect the mouse or keyboard to a USB 2.0 connector on the dock.

The charging speed for my device, such as a smartphone, is slow.

Connect your device to the Always On USB 3.1 connector Gen 2 on the dock.

My computer cannot be charged by the dock.

Ensure that:

You use the accompanying ac power adapter, power cord, and USB-C cable to set up the dock.
The USB-C connector on your computer supports ac input.

I cannot hear anything through the headphone or headset connected to the dock.

To use the audio connector on the dock, ensure that the dock is the default audio device of your computer. To set the dock as the default audio device:

Right-click the speaker icon in the Windows notification area and select Playback devices. The Sound window is displayed.
On the Playback tab, select ThinkPad USB-C Dock Gen2 USB Audio. Then click Set Default.
Click the Recording tab. Select ThinkPad USB-C Dock Gen2 USB Audio. Then click Set Default.
Click OK. Note: You might need to restart the application that is using the audio devices to apply the changes.

The external display is blank.

Ensure that:

Your computer is running correctly and is not in sleep or hibernation mode. When the computer is in sleep or hibernation mode, the external display is always blank.
The dock is securely connected to ac power, computer, and external display.
The dock driver is installed on your computer.
Reduce the resolution of the external display.
If the problem persists, disconnect all cables from the dock, and uninstall the dock driver. Then, reinstall the dock driver and reconnect all cables to the dock. If you cannot do this, please contact your local Net Tech for assistance.

I cannot play back videos on the external display but can play them back on the computer screen.

Some computers do not support High-bandwidth Digital-content Copy Protection (HDCP), so you cannot play back protected videos on the external display connected to the dock.
