[QUOTE="chscag, post: 1617903, member: 46727"] I'm not sure what it means but it sounds like a heat sensor error. A heat sensor error would cause the machine to shut down and restart. Of course that could also be caused by a defective component causing overheating - with the sensor re-acting to it. Time to take it to the genius bar. Apple does not charge for diagnostics as long as you use the genius bar. Of course if your Mac is out of warranty any repairs will be charged accordingly. [/QUOTE]
