Chapter 4. Troubleshooting
General
1. 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.
• The USB-C connector on your computer works well.
2. The charging speed for my device, such as a smartphone, is slow.
Connect your device to the Always On USB 3.1 connector Gen 1 on the dock.
3. 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.
Video output
1. 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.
• Reduce the resolution of the external display.
2. 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.
To play back videos on the external display, connect the external display to a DisplayPort or HDMI
connector on your computer. Then, set the display mode into extend mode or single-display mode from
your computer. See “Configure the external displays” on page 7.
3. The images on the external display flutter.
• Ensure that the display cable is securely connected to the dock.
• Disconnect and reconnect the display cable.
