I have had an ongoing problem with my powerbook going to sleep, staying asleep, and with the pulsating sleep light working. I found one other person on the forums with a powerbook and similar problems and he hasn't had the problem fully worked out with apple. I have a 1.5ghz PowerBook G4 12" SuperDrive running OS X 10.3.9. Soon after I purchased my computer the pulsating sleep light would not turn on if I put the computer to sleep, or it would stay on only for a short while, or it would only pulsate if I pushed in the latch button. It also would not always stay alseep when the screen was closed. It would sleep, then turn on, then go back to sleep, then turn on, etc. That problem has been taken care of (after 4 times being sent in). The other existing problem is that if you set the computer to go to sleep in say 3 min after not being used, it won't. It will never go to sleep. Instead, it will turn off the LCD after 3 min, and keep the rest of the computer running. It also runs the HD and fan so that my battery runs down. So if I leave my computer unplugged and on, and walk away and I come back 2 hours later my battery life has been greatly lowered. Is that not going to sleep an common issue with macs? I have tried everything to resolve it.... reinstall OS, PMU reset, repair permissions, zappage of the pramageg. ---- on another side note I pulled out my BT mouse that I haven't used in quite a while. I paired it with my pBook and went to move around the pointer. Instead of the pointer moving it stayed in place. I could click but not move. I restarted my computer, tried it again and its still broken.
