macbook heating up and turning off
i have a white macbook 2ghz. sometimes while charging and lid closed it heats up and when i open lid it will not start up from sleep (screen set to sleep, hard drive never sleeps) and i need to power off then on. when it charges and does not get hot (most of the time).... when i open lid it wakes from sleep normally. anyone know what the problem is? battery? fan? about to die? when it is hot i can not wake from sleep by opening lid or hitting space bar.
