Sleepless Puter

[pufnstuff]

Recently puter wouldn't go into Sleep Mode.
Tried just about everything suggested via Google searches

Following finally worked for me and posting as may help others
if have similiar problem.

From How To Geek ......
To resolve this problem in Windows Vista, run the powercfg -h on command

at an Administrative command prompt to enable the hibernate feature and the
hybrid sleep feature.

To run this command, follow these steps:

1. Click Start, click All Programs, and then click Accessories.

2. Right-click Command Prompt, click Run as administrator, type powercfg -h
on, and then press ENTER.

Forgot to mention, needed to uncheck
"Disable Hibernation Cleaner" in Disk Cleanup

Here's link if interested.

I tried this when I first got Vista and on a second Vista computer this
year, but it still hasn't gotten either computer to stay in Sleep. I think
it's something about other programs running, etc., but, whatever, I gave up
and no longer even try to use that function.

There are a number of things that will bring a PC out of sleep, such as Wake
On Lan settings. If your mouse gets moved enough, even from people walking
by, this can also wake a PC. Ever hear a car alarm go off, when somebody
just parks nearby and shuts their door?

It takes a bit more information to thoroughly track down these sorts of
things.

It took more "things" than I could figure out and finally gave up. It could
have been the screensaver, the Windows Update, One Care, etc. I just gave up
after infinite attempts to change the registry, etc.

Yes, if some service is running "under the hood" it may prevent the puter
from going into sleep mode. Times I remember sleep mode not working was when
the antivirus software was interferring in the background, I was running a
vbscript or some other service was running. Otherwise, sleep mode seems to
work about 95% of the time.

I've also found that some videos viewed in VLC prevent the system from going
to sleep, and prevent the screen from blanking. The only way to reset it
is to reboot.

There are a *lot* of variables.
