I don't know why, but I noticed that my LCD screen no longer turns off after the time set in the Windows Power Options panel. I have tried to turn off the screen with Wizmo and that works fine. The computer goes to sleep fine after the preset time and I don't think I have any running applications that would inhibit the power management features of Windows.

I have also tried changing my Power Plan and that has not changed anything. The screen saver is disabled as well. Any thoughts?

FWIW, I've seen the same issue with my desktop machine running Windows 7 RC. Sometimes the screen is turned off, other times it's not. Settings are all untouched. –  EmmEff Sep 1 '09 at 13:30

I think the problem is caused by Google Chrome. There is already a bug report opened here.

+1 Chrome was the problem here... just turning off Chrome was all I had to do to get the monitor to power off as usual –  Lee Harold Nov 25 '09 at 12:12
    
Problem has been fixed for a while now. –  JcMaco Feb 15 '11 at 3:19

If the Power Plan is defined correctly, then the monitor should turn off when the conditions happen. You should re-verify the parameters.

However, since you also say that you have no screen saver, you might try MonitorOffSaver which will do that for you without having to go thru Power Management.
