Hello NG,
I had a problem concerning the hibernation of Win7 that I've tried to fix for hours. Because I dindn't find a solution on the web, I just want to provide some information how to resolve the issue.
Problem:
After installing a new hard disk (>3Tb) as an additional HD, I was not able to hibernate. Windows seemed to hibernate (black screen) but after a few seconds, the login screen returned.
Unsuccessful steps:
-powercfg energy didn't show up an additional issue
-powercfg -h off then -on did not help
Successful steps:
-Although this was not related to the current issue I'm facing, the step helped the last time I had this kind of problem: Go to devmgmt.msc and check NICs and USB dev and Controllers -> Energy option->First option should be true (so that win is enabled
to hibernate the dev), second option depends on your wishes
-A collegue (non IT prof) told me that he has deleted the 100Mb primary partition and the reinstalled win. That was no option I could live with. Therefore, I checked bcdedit /enum /v and voilà an error occured. To fix this I went to computer management
msc -> Hard drive management-> assigned drive letter to the 100Mb prim partition. Afterwards, the command bcdedit /enum worked and the hibernate problem was fixed.
So, easy to solve, difficult to determine.
