I have recently installed new OS windows 7 Ultimate x64. When I try to put it into sleep mode, it instantly wakes and shows me my login screen. (Cpu fan runs all the time, it doesn't stop like it usually does). Then I tried to enable hibernation by running the following command in elevated command prompt "powercfg -h on".
No luck.
Hi andrejsavikin,
Try this to find out what is waking your PC.
Lastwake Command

I think that that might be it, will check it out as son as I get home. Thank you
Windows 7 can be really picky sometimes. Make sure your power plan is set to balanced and click on Restore default settings for this plan.
I don't think its that, my OS is newely installed
Wake History Count - 0 :/ (response from lastwake command)
Seems like disabling hybrid sleep allowed it to sleep. I have no idea why
Looks like you found the other tutorial link for dealing with this issue while viewing Lastwake.
