[QUOTE="dtravis7, post: 1566406, member: 8287"] PMU is Power Management Controller. SMC should be the same. On my 2007 you power it down and pull out the power cord and hold power down 5 seconds then plug it back in. Your 21.5 might be different. It was restarting all the time and quite annoying and has never done it since that reset. [/QUOTE]
