I left for class today and put my macbook in it's neopreene sleeve but for some reason it didn't go to sleep! So when I took it out an hour and a half later it was sooooooooo freaking hott. That nenepreene sleeve has 0 ventilation! Could this have damaged my macbook in anyway? Will it destroy the fans? screw up harddrive? damage the light for the LCD? Please help!
