Hi Matt, Most of using PowerBooks have experienced these issues from time to time. I've had all the ones you described. I use a 15" 1.25 at work and a 17" 1.0 at home. Both of them have had these issues. Apple have released patch updates that have supposedly addressed PowerBook sleep issues but for me they never went away. Take it as a user feature and just make sure you don't leave unsaved work at the end of the day. Coj Matt Gregory <vdub.grego at gmail.com> I've had some strange behavior out of my PowerBook and wanted to see if anyone has experienced this or can offer any advice. It's only done this twice and I can't recreate the problem, so the details may be a bit fuzzy. When I use the PowerBook (15" SuperDrive) I, per the manual, usually just close the lid between uses unless I'm going to transport it somewhere. Well, twice now it's not woken back up after being closed. Both times I believe it has been closed over night before opening it again. The space bar is usually how I wake it up if it's gone to sleep while open, but it doesn't work in this situation. The second time it happened, pushing the power button powered it back up as if it had been powered down, but I'm positive it hadn't (unless I managed to do it accidentally). But the first time I was unable to wake it back up by any means and resorted to removing the battery and putting it back in. After that it powered up fine. Both times the battery had about mid-charge. The PB is only 4-5 months old and is not one that falls under the battery recall. Any advice? This is my first Mac, so I could be doing something unknowingly, but I can't imagine what. Thanks, matt.
