Hey all. I'm not sure if this is a software or a hardware problem, so I put it in this thread. This evening, my PowerBook began having a very frustrating problem. It goes to sleep every few seconds, often within one or two seconds of re-awakening it. I can't get anything done on it, and it's hard to lock down the problem when I can't complete even a simple web search or a quick post. Here's a partial list of what I've tried: - Checking Energy Saver settings for anything weird. - Resetting PRAM - Resetting PMU - Trying a safe boot - Rebooting without the battery installed - Reinstalling 10.3.7 (in case it was the recent update that buggered it) - Charging the battery completely and attempting to drain it (it going to sleep literally every 1-45 seconds will make it hard to drain completely and recalibrate) - Shutting down the 'book and leaving the battery and AC adapter disconnected for 10 minutes. I'm at a loss at what would be causing this all of the sudden. I haven't installed any new software, except the latest 10.3.9 and security updates. I haven't changed any system settings to my knowledge, and today has held the first reboots since the software update. I hope someone here has the solution (and I apologize if there's a thread on this somewhere; I can't get through anything long enough to find an answer, and I'm away from my other computers at the moment). This post took 20 minutes to type, with all the sleeping and resuming I've been stuck with.
