A bit earlier, my MBP inexplicably restarted on me after I closed the lid, a few seconds elapsing between the time I put it down and walked a few feet away and then heard the chime. When OS X was back up, I noticed that the temperature had somehow spiked to about 150+ degrees F, which somehow happened in the space of a few minutes of little real usage (and while set to max energy savings). Also, Activity Monitor is not showing me any processes, no matter what I do. It's just blank. No program usage or any changes can make it show a single process. It was fine yesterday. Any help?
