I put my macbook to sleep last night plugged in at 100% battery charge. Everything was fine and normal. When I opened it this morning it did not wake up; the screen stayed dark. The fans were also going full blast, yet the machine was hotter than I've ever felt it. It would not wake from sleep, and I had to do a hard shut-down. I let it cool down completely and then powered it back on. It started up normally and seems ok now. Anyone know what's going on? I've read about people on this board having this issue with G5 towers I think... (came home to find the fans roaring on a sleeping G5) I'm worried... please help.
