Suddenly the hibernation mode on my machine stopped working. \

Symptoms:
When I "hibernate" is still available in under "Shut down" but when I pushit - the pc screen gos off for a 2 seconds, then the pc is on again.

What I tried:

  • Tried to dis- / enable hibernation via powercfg -h off powercfg -h on
  • Tried to disable and reenable S3 in BIOS
  • disabled awaking via mouse and keyboard
  • checked powercfg -requests which is empty
  • killed every service, which is not from Microsoft

Any ideas?

Update:
I did a safeboot via msconfig - hibernate worked as charm. However when I switch to normal boot - hibernate still does not work

Storage space full? Hibernating requires as much free space as you have RAM. –  Trengot Apr 24 at 21:38

The first step. Boot into a minimal startup configuration. This will prevent any program that normally starts up that is preventing the computer going into hibernation. If it works update the question and we can go from there. If it does not no harm done. –  Ramhound Apr 24 at 21:41
    
I tried a safeboot and hibernate worked. But in normal boot it still doesnt work.. –  Skip Apr 25 at 7:23
    
@Skip well do ctrl-shift-escape (that's task manager), and look at what processes are in normal boot but not in minimal. Try booting normally and closing unnecessary processes and try hibernating. troubleshooting like that. and by process of elimination you may find the suspect –  barlop Apr 26 at 21:05

@Skip did u terminate all processes such that in normal mode u have exactly the same processes as in minimal mode? I wonder if maybe a process is reading c:\hiberfil.sys u could try sysinternals process monitor n make a filter to look for that file.also process explorer-find...find handle..hiberfil.sys or hiberfil. see if process monitor and process explorer show anything. Also, btw, this may not help but process explorer if you hover over a system process like svchost.exe it can show u the services associated which is useful if u know the offending service or wanted an idea of one to test –  barlop Apr 28 at 1:07

My solution was to restore Windows from backup, which as I understand isn't a real solution

Try using this in "Run" (Ctrl+R) :

cmd /c shutdown /h & exit

Or you should use taskmgr to check whether some programs are running to prevent you from hibernating. If you still can't solve it, you may need to re-install your windows again.

Cleaning the power button may be a silly method, but you'd better try.

EDIT---

Reading your comments, you should try checking your SERVICE. Yes, service in taskmgr! Process may not show some of the background-process running.
