Do you have a Display port monitor, by any chance?

After adding one, I found out that when the display goes to sleep, Windows sees it as a disconnection, and 'helpfully' wakes up to reorganize all the windows onto one display. That wakes up the Display port monitor, which triggers another reorganization, and the cycle begins again.

So that's what it is. Got a TV connected via a D-port to HDMI adapter and the stupid machine wakes when I want to just turn off the TV after I put the PC to sleep.

Googling didn't get me too far obviously.

yes I do! I have noticed the sleep == disconnect thing. I'll look into it, thanks.

Serendipitous.
