Unable to enter sleep/hibernation, black screen instead
Hi,
Recently, I 'fixed' my dual boot system so that I could boot without windows again, using a recovery disk with bootrec.exe \fixmbr and bootrec.exe \fixbcd. The computer is booting properly now.
However, it has developed a problem. I can no longer enter sleep or hibernation. When trying either, the screen will fade to black as expected, but then nothing will happen; no keypresses will turn the screen on again. In the meantime, the computer seems to work 'normal', just with the screen off. After a while, the computer will simply power off and I will be greeted with 'windows didn't shut down successfully' upon restart.
I updated my drivers, updated and removed the Lenovo Power Manager, updated and resetted the BIOS, and checked powercfg -A which looks the way it should according to what I found on the internet.
Can anyone help me?
