ThinkPad Pro Docking Station (40AH0135EU) and X1 Carbon G6 20KH issue



I have follow issue on subject. Several times per day docking station going unexpectedly to disconnect displayport and power delivery, wherein no power interruption observed in any way. It looks like docking station power is lost, but all of usb ports and ethernet port continue to work normally and doсking station power light is on, wherein laptop is on battary mode and external monitor have no signal. Return to normal mode can only obtained with turn off and on docking station power.

Laptop, docking station, thunderbold firmware and all of drivers renewed and up to date.


Does anyone have any ideas? Thanks in advance.
