when I undock my X280 from the Ultra dock (notebook closed but running) and open the lid the device will not respond to keyboard or trackpoint input.
I need to close the lid again which triggers entering 'energy saving' mode.
Then opening the lid again will resume everything to normal. I can reproduce this every time on two identical Docks.
Funny thing is, my wifes identical X280 does not show this behaviour but works fine.
Any idea what I could try to solve this small (but a bit annoying issue)?
