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?
