howdy. after much contemplating i finally swtiched to mac and so for have been digging everything about OS X. My only problem is that my occasionaly my macbook doesn't want to wake up. typically i should be able to open the lid, hit a key, or hit the mouse (kensington blue tooth) and it should fire right back up right? well three times now in the past week, (i've only had it for two weeks) i've tried to wake it up and i get nothing. i've done everything that should wake it up but the screen stays black and the light on the front of the mac, which usually is pulsating when asleep, is on full bright. i've reset the power settings with the help of apple care, and also de-selected "put hard disk to sleep when possible" but it hasn't seemed to help. again this only happens occasionaly. any thoughts?
