It sits upstairs on a desk all by itself. I'm the only one that touches it. It does it like once and hour or so. When I see it happen. It sometimes wakes when I'm walking up to it. I initially just figured my steps shook the table slightly it sat on activating the mouse lazer or something. But then my wife and I started noticing it turning on in the middle of the night while there is no movement happening. My screen is set to go off after 15 minutes of inactivity. And to allow to sleep when screen is off. Anyone else experience this? Any reason why? Doesn't really bother me other than I don't like it having a mind of its own. PS when it turns on it is the login in screen and I don't log on so it turns off after minute or so.
