Hi guys I have a 3 week old 3.2 GHz Intel Core i3 Mac. Last night I put it to sleep and it kept coming on by itself. So, in the end I shut it down completely. To my amazement, 45mins later it turned itself on. It was not in sleep - it was completely off. How is this possible? I checked the system log, and I can see the point that it woke up but cannot determine from this why it turned itself on. I have a USB hub connected and a wireless keyboard and mouse.
