Well, this sure is an odd issue to say the least. If my new Macbook Pro (2012, cMBP) stays asleep for a few+ hours, it's no longer asleep but, as best as I can describe it, it's hibernating. The sleep indicator is off, the power charger is plugged in, but when I open the lid, the screen is grey and it's like an indicator bar is filling up before it will show the desktop. If I let it sleep for a few minutes it comes up with no issues. SMC has been reset (probably multiple times to make sure I did it correctly). The problem still exists. Any advice?
