Chapter 5. Troubleshooting
This chapter provides some troubleshooting hints and tips to assist you if you experience any problems with
the dock. Check the following items first to try to solve the problem.
General
1. The dock does not work after connected to a computer with the provided USB-C cable.
• Ensure that the dock is correctly connected to the power adapter. The dock always needs external
power adapter for operation, because it does not get power supply from the USB connector attached
to your computer.
• Ensure that the device driver of the dock is installed; if not, install the device driver and restart the
computer.
2. The 2.4 GHz wireless keyboard or 2.4 GHz wireless mouse function is interrupted. The mouse
pointer lags or it cannot move. Some characters are lost when you input by the keyboard.
It is recommended that you connect your 2.4 GHz device receiver to the front USB 3.0 connector on the
dock and avoid connecting another USB 3.0 device next to the connector with the receiver attached.
3. The charging speed becomes slow, after I connect my device (such as a mobile phone) to the
dock for charging.
Ensure that you connect your mobile phone to the Always On USB 3.0 connector. Disconnect the dock
from the computer, the charging speed might become faster.
4. The mobile phones or other USB devices cannot be charged when connected to the Always On
USB 3.0 connector.
It is recommended that you can disconnect the dock from the computer, and then you can charge the
mobile phones or other USB devices.
5. The mouse and keyboard cannot wake up my computer when connected to the Always On
USB 3.0 connector.
Ensure that you connect your keyboard and mouse to other USB connectors on the dock instead
of the Always On USB 3.0 connector.
6. The computer is not charged after connected to the dock.
Ensure that you use the power adapter that shipped with the dock.
Video output
1. The external monitor display is blank.
• Ensure that the computer connected to the dock is running correctly and is not in standby or
hibernation mode. When the computer is in standby or hibernation mode, the external monitor
display is always blank.
• Ensure that the device driver is installed following the installation instructions.
• Ensure that the following connections are correct:
– The connection between the USB-C cable and your computer
– The connection between the USB-C cable and the dock
– The connection among the power adapter, the dock, and the electrical outlet
– The connection between your video cable to the dock and the external monitor.
If the problem persists, disconnect all connections of the dock, and uninstall the dock device driver.
Then, reinstall the device driver and the dock.
