Alright, I wonder if anyone else is having this same issue. I'm getting this strange behavior that doesn't quite match other user's with the wake from sleep bug. Basically I wake up in the middle of the night to the sound of the rMBP fans going at a decent clip, not maxed but definitely doing some work. The case is definitely warm. The laptop lid is closed and the only things that I think that are relevant are: * PowerNap is off (i thought it might be PowerNap, nope) * Lid is closed * 23" cinema display plugged in via a Thunderbolt(MDP->DVI) adapter * Logitech wireless mouse dongle It has happened about 3 times now and is starting to concern me. When I flip the lid open the screen stays black and I get no sounds from the keys. Only way to recover is to hard reboot by holding the power button. Other than this issue, everything is working great (mostly graphical glitches, otherwise). I'm going to try unplugging the cinema display and mouse to see if the issue happens again, but was curious if anyone else was experiencing similar issues.
