Windows 7 will not go to sleep

I have checked the power options in the control panel and yet the PC will not sleep after the preset times.  Any ideas what the problem is?

Re: Windows 7 will not go to sleep

There are quite a few programs around that prevent sleep.  You can try using something like Task Manager or Process Hacker to kill one at a time to find the offending one;  rather a slow and boring process sadly.  If you have just installed something new and the problem started that is probably the reason.
I recently had this with a program called Air Parrot; I was able to pin it down fairly quickly because it was a recent install.
I don't know of any quick way to find out what has rejected a Sleep request: maybe there will be an indication in the Windows lots.

Go to an admin command prompt and type

powercfg /requests

That would be my starting point.
Anything not appearing in there is going to be harder to track down.
