Ok I have had my MB pro just over 2 years now. Issue free thus far. Recently I have had it on and within 15 mins it just shuts off. LIke i held the power button in. Totally freaking me out. Is there a scan tool or something i can download? Is there anything I should look for? I took of my SPECK case but I have never had issue with that in the past have had the laptop in a plastic case since day 1. Any suggestions or help would be great thanks.
