Oh, I am a genius. I’ve had a problem like this for a very long time, where I can’t seem to get the monitor to turn off after the time specified in the Power Options. Annoying? YES! Problematic? YES!
Well, tonight, I spent about 15 minutes trying to find a solution, by closing programs one by one and using the “1 minute” shut-off time. It would shut off in 1 minute, but turn back on immediately without me doing anything. Confusing as hell! I figured some program triggered an event that turned the screen back on. I got down to nothing but the “usuals” running, things I’d been using forever, and gave up on that option.
I looked somewhere else… the screensaver. I had recently set mine to “none”, but left the timer at “1 minute”. There was the problem – no screensaver was active, but the timer was still counting to 1 minute. When they both were triggered at the same time, the screen would turn off, then try to go to screensaver.
It seems that when the screensaver time is set above the power-off time, it will override the power-off event and turn the screen back on. Solution? Set the power-off and screensaver to different times – above or below each other, it doesn’t matter. As long as one event is triggered at a different time than the other, they won’t cancel each other out. 🙂
