So if I plug in my rMBP and walk away for a while, when I come back (randomly) I will touch the trackpad and the screen will turn on. Mouse moves, I can click on things, but only for about 5-10 seconds. Then the screen will go black and it will sit there doing nothing for about 20-30 seconds then it will work fine again from there on out. No clue what is going on, it doesn't seem to create any harm or anything but it is kind of weird. Anyone have any ideas?
