I just got my new MP on Monday. Seems like every time it goes to sleep it reboots when I wake it up. After searching this forum it seems other people have the same problem. I repaired the disk image and that seemed to help for a couple of days but now it is back to rebooting. Sometimes when I try to wake it up I hear the fans kick on but the screen never appears. Kind of frustrating after waiting forever for the new MP to come out, I have these kinds of problems with it. On the positive side, with the Raptor boot drive I installed, this thing is up and running in 20 seconds literally.
