Symptoms

The power button LED on the dock may turn off and stop functioning when undocking and immediately re-docking to XPS 13 9300. However, it does not impact the USB2, USB3, DisplayPort, HDMI, LAN, or Audio functionality.

Affected Configurations:

  • Dell Dock WD19 with XPS 13 9300
  • Dell Dock WD19S with XPS 13 9300

Cause

This is working as designed. Dell Docking Electronic and Communication (EC) delays for a period of time for USB Hub to begin initialization when you attach or detach the dock to the computer. If you detach the Docking Station from the computer and connect immediately, the docking station fails to initialize and does not function properly. This applies to all Dell Docking stations.

Resolution

Remove the dock and wait for a few seconds before reinserting it into the computer.
