So, it is the second time this has happened to my Alum MacBook and I am wondering if it is (1) normal (which I do not think) or (2) happening to anyone else? So when I close the lid of my Alum MB, it goes to sleep fine. If I wake it up in like 10 mins its fine. Where the problem lies is if I close the lid and allow to it sleep over night and I wake it up in the morning (by opening the lid) the MB makes its usual noises and then does nothing. The screen is black, the sleep light is off - the power button doesnt work. The only thing that works is unplugging it and taking out the battery. Something weird and Im not sure what is up....anyone else?
