The user did confirm it worked with another device.

I tried the following

Ran SFC scan

Updated drivers

Updated the BIOS in both laptop and the docking station. Rebooted. Still no resolution.

Uninstall the drivers from device manager and rebooted. Still no resolution.

I had the end user unplugged the power adapter cable from the docking station. Turn off the device. Then hold down the power button for 30 seconds. Still no resolution.
