MacBook Pro won't "wake" up after sleep mode!
Sometimes, after my MacBook goes to sleep, it will not wake up! I press every single key and tried closing and reopening the MacBook but the screen remains black. However the indicator light that pulstates while it is in sleep mode does turn off after the first attempt at trying to wake it up. After that if i close the MacBook again the light will not pulsate. I always end up having to manually shut down my MacBook and boot again. Has anybody else had this problem? It only occurs once in a while but is very annoying. Any ideas?
Powerbook G4 15", Mac OS X (10.5.1)
