Sleep Option greyed out.

Title says it all. I have all the power down options available EXCEPT Sleep. It is greyed out(even in safe mode). I've searched the forums and found multiple threads. I have tried the registry tweaks, self-executable files to reactivate sleep, etc. all to no avail. The only other unfortunate option left is to reinstall 7
Other suggestions are much appreciated!

FYI: AND no, it's not related to graphics card. This option WAS available until, I believe, after an automatic win7 update. I DID try to revert; no luck.

P.S. I apologize if not in right forum.

Press the Start button, then press the right arrow key twice, then press the letter S - what happens?

Hello BPetkus, and welcome to Seven Forums.

You might see if this may be the issue.

Sleep : Disable in Shut Down Menu

Hope this helps,

Nope, I already tried that one too. Reset value to 1.....no luck.

If you go back into the registry, is it set to 0 again?

Hi,

Can you try this:

Open an elevated CMD window, and then type powercfg -a and hit enter.

Post the resultant output here.

Hi,

Try the following :

1. Download and install latest display driver from the manufacturers website.
2. In an elevated CMD window, type powercfg /hibernate on

Run powercfg -a again, and post result here - it should say that hibernation has been turned back on, and that sleep is now supported.

If it is, see if SLEEP is nowavailable, or still greyed out.
