[QUOTE="walkerj, post: 351640, member: 9385"] Mine did that once shortly after I got it. Same thing, noted battery charge in the upper 90s, closed lid to have it 'sleep' overnight. Next day, wouldn't wake up until I connected it to power. When it finally awoke (I may have had to restart it, I don't recall) battery was at 7%. Applecare walked me through resetting the Power Management System, which if I recall involved powering it completely down, removing the battery, pressing the power button for 15 seconds, putting the battery back in, then charging. Hasn't happened since. [/QUOTE]
