Hey!
If I close my laptop, sometimes the fans are still running in closed status. If I then open it again, I get black screen with fan running full power after hibernate. The only thing I can do, is to press the power button for a long time and to shut it down. But it happens just sometime, not always. I could not reconstruct the issue for sure.
I’m running atest QubesOS on Thinkpad W530 and I had no such problems earlier with that machine.
I did nothing special, just regular updates for dom0. So maby some updates cause this problem.
Bets regards
