I have another very nasty issue...
My system fails to enter Standby or Hibernation. When I start the process, the monitor fades out to black - as normal - and the system begins to disable devices. I can see i.e. that an attached USB-Stick gets turned off. Unluckily, Windows seems to get stuck in between - my WLAN-Card seems to stay on (indicated by its LED), and the system just gets stuck there. (Interestingly, although the WLAN-Card stays on, the computer seems to disconnect correctly - I can't RDP in in this state.) I have to hold the power switch for 4 seconds to stop that situation.
The behavior started a few days ago, while I was messing around with my drivers because of another (unrelated) issue. Unluckily, System Restore doesn't want to go back, so I'll have to find another solution.
My biggest problem: I just can't find a way to analyze what device is causing the problem - the Event Log shows nothing of interest, and I can't think of other important logs.
Does anyone have an idea what may cause this or how to debug that issue?
Thank you for your help!
