    I have a 2.4 Ghz Intel Core 2 Duo Unibody MacBook. Lately I have had shutdowns at no more than 75 C and fans at 5500 rpm (using SMC Fan control) and battery at 30% or greater. It is a sudden shutdown. Granted the fans keep going for a while on Skype but this is not hot enough for a thermal shutdown. What is this? Please advise.

    Backup your data and go in to the apple store... They will either (a) replace your MacBook (highly unlikely) or (b) replace the logic board. But, there is a possibility that when they replace your logic board that they accidentally damage your hard drive (thus resulting in a new one). Take a video of the random shutdowns if at all possible, in case you can't reproduce it at the apple store.

    Not entirely sure that this is a logic board issue. Maybe try a battery calibration first.
