Windows 7 Monitor will Sleep, Computer Won't

Type msinfo32 in the start menu then press enter. File | save on the opened screen. Then zip the saved .nfo file. Attach the zip to a post and I can have a look at your current system to see what might be causing issues for you.

OK here it is... thanks in advance mate.

Hey Cusco,

You have an old Realtek HD Audio driver, so you can update that from here:



Your video driver is ancient, from January 12, 2008. There isn't any update for it and the problem is likely caused by it, so this problem you're having on 64 bit might be a permanent one with your particular hardware.
Hi TorrentG,

Thanks for taking the dedicated time to look.

I don't mind that my gfx card is now considered "legacy" by ATI. I will update my realtek driver, but I don't think that either of these drivers is causing the problem.

I had them long enough and this issue is just too recent. The ATI driver was there before and I could put my computer to sleep...

Suddently I installed Linux (Debian, with grub dual-boot, and can put the computer in sleep state S3)...

After a while I left my laptop with my girlfriend and later we noticed that it wouldn't sleep....

Im guessing that re-installing windows will fix it...
