What did the battery indicator on the battery indicate the charge was? Was the battery loose? Otherwise, the proper sequence of events to shut down the powerbook is to first hold the power button down for 5-10 sec. Then press the power button once. If you did this in reverse, you may have done nothing when you pressed it once, then shut it down when you held it down for a while. Then an hour later, you pressed the button to turn it on and it came on. Next time this happens, hold the powerbook screen up to a light source and see if the Kernel Panic screen is there but the screen brightness is off. You may have had a panic on wake, the screen did not wake up and brighten, and that's why the computer never woke up.
