My Windows 7 (x86, Pro) laptop no longer hibernates. When I tell it via power button or "shutdown /h /f" it fades out the screen to black, but doesn't do anything else. Doesn't even go into a sleep state. Hitting a key pops the screen back on.
I've tried disabling and reenabling hibernation to clear the hiberfil.sys, but it makes no difference. If hibernation is disabled, sleep works fine.
This problem started happening immediately after swapping hard drives. I used Ghost 14 to restore a backup to a new drive then plugged it in. Windows wouldn't boot (BOOTMGR problem) so I ran a repair from the Win7 disc. It's been working fine since, aside from inability to hibernate.
Nothing is showing up in the event log that seems new or relevant.
Any ideas on how I can diagnose or resolve this?
