Windows 7: What could prevent Windows from turning screen off?

What could prevent Windows from turning screen off?


I noticed in the past few weeks that my laptop doesn't turn display off when I leave it on idle.
My current settings are "dim display after 2 minutes" and "turn display off after 5 minutes"... yet nothing happens even after hours..
I think this is because a certain program overrides the default Windows settings. How could I find out which one?

Hi Coyote,

Did you install/update any 3rd party programs or install a new device, just before this issue started??

I have my USB receiver plugged in (Logitech) for my mouse, but that's never been a problem.
As for software, I use Logitech SetPoint and HwInfo64 (running currently), I don't think these would affect Windows (they don't even have screen-related settings)

How can I prevent my keyboard from turning on my computer?
I set the mouse not to wake up my computer, and that's great.. I do like to wake it with the keyboard though so I left that on.. What I would be happy to do now is to keep my keyboard from turning on my computer when I turn it all the way off.. I'd like just the button on the front to do that. ...
