Something's putting my netbook to sleep. Acer Aspire One 722 only a couple weeks out of the box, Win 7 Premium. Before the start of Daylight Saving Time it was going to sleep at 5:00 AM. Now it's going to sleep at 6:00 AM. Thoughts on the culprit? Acer Tech Support was entirely unhelpful. Haven't visited any dodgy sites (honest) or installed doubtful software.
