Windows 7: Win 7 64Bit not going to sleep all the time.

Win 7 64Bit not going to sleep all the time.

How can I find out if there is a program or peice of hardware the prevents my computer from going to sleep? Sometimes it does and sometimes it does not.

My displays are set to shut off after 10 minutes, which they do. My computer is set to sleep after 30 minutes. I changed the displays to 5 minutes and the computer to 15 minutes. The displays still shut off but the computer might not.

I'd say check what processes are running when it does go to sleep properly, and check the processes when it does not, and see if there are any odd ones. Does the computer go to sleep if you tell it manually?

Try running a malware scan with Malwarebytes: Malwarebytes : Free anti-malware, anti-virus and spyware removal download
Also, try running sfc /scannow in an administrative command prompt (right click on cmd and select "run as an administrator")

Did the Malwarebytes thing. Found nothing. Computer goes to sleep normally if I click on sleep.
I thought you could look in Event Viewer and find something in there. Did SFC also.
I guess I have to start uninstalling programs to see if there is a conflict. Maybe unplugging my USB printer.

Unplugged the printer, still the same.
I'm totally confused.

Check in Power Options that you don't have the setting to prevent sleep when sharing media turned on.

It's in Power Options > Change plan settings > Change advanced power settings > scroll down to Multimedia Settings.

It's set for the default "Prevent idling to sleep".
I have the Balanced plan selected and everything is set to default. The computer goes to sleep sometimes.
I have a book on Windows 7 that deals with more in depth stuff than the "how to use Windows 7 books".

I was looking through the book and came across the Power troubleshooter. So I ran that and it said it found/fixed one problem, the screensaver was turned on. I don't remember turning it on. So I'm going to leave the computer alone and see if it goes to sleep properly.

Then that means the computer won't go to sleep if it's sharing media... You may not be sharing media, but even if media sharing is enabled this can sometimes stop it from sleeping.

Hello HAVOC,

I had the same issue as you did last year. There are a couple of things you can try. Firstly, as CreepinJesus says you can alter the media sharing option in power to "Allow Computer To Sleep".
Also you can go to Device Manager and Uncheck the option for "Allow this device to wake this computer". Do this for both the Keyboard and Mouse, see if that makes a difference.
Also, do you have an external Hard Drive connected to the PC at all?

Also do this for any network interface that you're not using for Wake-On-LAN, or WoL.
