Windows 7: S3 sleep (suspend to RAM) not working

17 Aug 2011   #11

Windows 7 Ultimate x86

It always has been this way.

BIOS default setting. All drivers through the standard genuine Windows 7 Ultimate x86 install and Windows update. All downloaded apps are open source, except Microsoft applications and games, which are all bought in stores in terms of physical media or on Steam (Only Valve and id software games).

I never updated the BIOS, but that isn't a problem to do because I have a non-writeable recovery BIOS and a seperate writeable BIOS.

Oh and I have Service Pack 1 installed.

Interesting. So you can create a hibernation file (powercfg -h on), but you don't get hybrid sleep at all?

All I know about that hiberfile is that when I type 'powercfg -h on' in the cmd.exe with admin rights, it prints a blank line and returns to the prompt.

Nothing is affected after reboot.

I must add that I only have general knowledge about the NT6 architecture and what it does, but I don't have indept knowledge about the registery and the various options and commands in NT6.

I gues I should load that config file somewhere?

Someone else seems to have had a similar problem, which we were able to solve. I'm not sure if this will work for you, but it might be worth a try, unless cluberti has other suggestions.

Try this:

powercfg -h turn off, and then
powercfg -h turn it back on again

This "reset" seems to have helped the other person, so I'm hoping perhaps it could help you too.

Can you update your system specs in your profile, and then output what powercfg /a shows you here? I'm interested in both.

I just built a new computer and had it running stable for several days with all hardware except the graphics card and a new monitor. After plugging the new video card, I believe the system remained stable, but am not 100% confident since it only survived overnight. After plugging the new monitor...

How do you normally suspend your computer?
Just a question out of curiosity, I'm wondering how you guys normally suspend your computer. As in hibernation, shutdown, sleep, or yank the powercable and remove the battery hehe. Personally, ever since 7, I pretty much always simply leave my computer in sleep mode. Wakeups are so quick, and...
