The powercfg command option will give you alot of information about your computer's sleep congifuration. It will help troubleshoot your problems. Take a look at the link below for details on how to use it.

that weblink told me a lot by the way i found something for everyone that you may or may of not seen
Here it is:
IF YOU HAVE EVER RUNNED DISK CLEANUP DO THIS!
1. open start menu
2. type cmd in the white line (Start Search) area
3. right click on the cmd (at top)
4. click Run as administrator
5. type powercfg -h on and press Enter
6. close command prompt when it's finished
This worked magnificently. Sleep works Again!!! Just to clarify davmcn's post, here it is again with a little more detail. When using disk cleanup, if you cleaned the hibernation file because you never intend to use it, it disables sleep. Here's how you reverse it:
IF YOU HAVE EVER RUN DISK CLEANUP DO THIS!
1. open start menu
2. type "cmd" (without quotation marks " ") in the white line (Start Search) area
3. right click on the cmd.exe (at top of the list)
4. click Run as administrator
5. type "powercfg -h on" (without quotation marks " ") and press Enter
6. close command prompt when it's finished
7. run the disk cleanup utility (start/all programs/accessories/system tools/ disk cleanup) then uncheck "Hibernation" so it doesn't happen again.
Voila, problem should solved!
This did not work. Have you found another solution yet?
Turning on all of the sleep stuff in the bios fixed it for me.
I had 2 problems...if I kept hybrid sleep enabled, I couldn't get it to come out of that mode. If I turned off Hybrid, and turned on Hibernate, it rebooted.
It now works perfectly (hopefully it'll last, sense I'm leaving it with my parents....and it's tough to fix bios issues over the phone.
ok what you have to do is go to the bios go to Power and disable "XD (Execute Return). After whne you return to Windows Vista it should all work
Hope this helps

Ok well i worked for like a couple of hours hibernation and Sleep worked but now It's gone Now i am seeing why some people want to downgrade from vista to Xp. i am really frustrated with vista if this isn't fixed by microsoft. i am thinking of just going back to Xp.
My 8800GTS 640MB had this problem until I updated my drivers. Poof, working now.

But i would check with your manufactuer First.
I had the same problem; what I did was to uninstall the graphic driver fully and re-install the lates driver from the manufacurer's site. It sorted out the problem. Microsoft update is of little help in situations of this kind
My computer is a notebook Aspire 5102 with windows vista. I have the same problem. sleep turned out to be a dead mode, fan's running with a black screen. The only way to escape is to hold the power key.
I tried many many ways to figure that out, I even rolled back by reinstall but after install several updates the problem came.
I can't stand that a notebook can't sleep. So I finally determine to turn off the hibernate by command prompt. Now sleep mode is definitely fine, but computer can never hibernate of course. I don't know if it's the microsoft's problem. I hope they could fix it
