So, while visiting my fathers house in washington, my computer (powerbook g4) began to uncontrollibly fall asleep. the screen continues to completely black out, and the little light pulses on the button. i can close it, re-open it, or press the power button, and it will wake up. But, after doing this like 10 times the computer completely locks up. Also, if i leave it alone for a while, it takes longer to go to sleep, but when i keep waking it back up the intervals usually become shorter until eventually freezing up. I have a suspicion that this may have been cauused by a surge as i was not plugged into a surge protector as i should have been. Any help?
