Why does my MacBook Air not go to sleep?
My MacBook Air (revA) won't go to sleep with the lid closed. The fan continuously runs and the Apple logo light on the lid goes on and off randomly. Added to that when I run Safari, the menu's randomly cycle rapidly through on their on until I hit the esc key. I tried multiple PRAM resets but that didn't work. I finally tried an SMC reset and that worked, although my left shift key stopped working after the reset. 48 hours later all the same problems started up again. Could this be a problem with the motherboard or main battery and should they be replaced or repaired?
