Win 7 Computer will not auto sleep

post #1 of 4
Thread Starter 
So I have a HTPC that I use for watching movies off of my home server. After watching a movie (or doing anything really), the computer does not go to sleep. It is set to sleep after 15 min of inactivity through the control panel power settings, and there are no programs that I can tell that are causing it to stay awake. Virtually all programs and tasks are closed, but its staying awake. If I manually put it to sleep everything works fine. Is there a way that I can tell what program is keeping the computer from sleeping?

Also, as a similar but unrelated question, is there a way to allow a program that keeps the computer from sleeping while its running (hard drive sentinal) to keep running but still allow the computer to sleep? Thanks.

disconnect the internet and then check it out. And make sure your Bios suspend mode is S3.

If a computer is in sleep mode, no program can be active or runnning.

I didnt even think to check bios settings, I'll give that a shot. Thanks. Hopefully its as simple as that, because if its some background process or something I can see it being a real grimlin.

Problem solved. It ended up being the Intel HD graphics driver. Updated to the newest one and the problem is solved. I figured it out by checking out resmon to see what was consuming cpu cycles.
