cannot fully enter sleep

cannot fully enter sleep [SOLVED]

This problem is random; one day last week, my vista x64 machine stopped going into sleep mode. Whenever I select sleep, the screen goes black, but the system never powers off - it just sits there, still running. If i move the mouse, the screen comes back on, almost like it never went into sleep mode at all.

I've got all updated drivers & BIOS for the motherboard (Asus Crosshair II formula) It's really wierd - I can't think of anything I did to cause this. I'm actually kind of getting fed up with vista (this isn't the only "random" problem I've had with vista, and I'll tell you XP, for all its faults, ran perfectly fine)

I'd really like to get this working, as I have a ****tily-paying job and would like to reduce my power bill as much as I can. I know I could just power the entire computer down, but I'm lazy and, well, I guess I expect features that exist to, you know, work.

Any ideas guys? btw it looks like this is a rather helpful forum.

This happened to my computer and it was easily fixed by running a scan. Here is how to do it:

Click Start, then type cmd into the "Start Search". Right-click it and select "Run as Administrator".

Now type in the following:
sfc /scannow

{Note there is a space between the "sfc" and "/scannow"} (see Pic1).

When the scan is complete, restart your computer.

I did this and it was fixed! My friend had the same problem last week, but the didn't fix it. It's worth a try anyway!

Yeah, that did absolutely nothing.

Thanks for the suggestion. any others?

You can also check power options in control panel. Under the power options your computer is on when the problem happens choose advance options, scroll down to multimedia settings and change to "allow computer to sleep". I solved this problems twice doing this

Bingo, that was it.

Gah, after ~7 years of XP, Vista still screws with me sometimes. It's like they changed things just to change things - and that, IMHO, is the worst kind of change.

Thanks guys.

Expect this to happen ounce in a while. I think some multimedia apps change that setting randomly, but now you know what to do.
