I had given my laptop for a video driver software installation but after getting it back, I noticed that my sleep and hibernation options are faded in the start menu and if I close my laptop's lid, the screen turns black but my laptop still continues working. I tried searching for many answers but unfortunately could find none which would solve my problem. Also, if I check for driver versions and model through dxdiag, it doesn't show anything.
The results it shows:
I use 32-bit Windows 7 Ultimate.
Can anyone please help me out?
