Just in case anybody has seen this or knows what it might be...
Some weeks ago (perhaps circumstantially, shortly after installing the seed CD of Panther), my TiBook 800/DVI started 'dying' in its sleep. Usually after a night asleep, I'd find it in the morning with the sleep light out, no longer pulsing, and the 'book would be dead to the world. No key combinations, power key, etc. could make it stir. Popping up the keyboard and pressing the PMU reset switch would, however, completely restore the machine.
After considerable trial and error, I have found that the machine continues to function completely normally, sleeping, awakening, etc. etc. so long as I am careful with the battery charger:
If the machine is left asleep with the battery charger attached and in 'fast charge' mode (the connector glowing yellow), it will 'die' during the night, and require a PMU reset to resurrect.
If the charger is glowing green, it's OK to leave the book asleep--for days even, there's never a problem.
If the charger is not connected, the book will sleep, slowly drawing down the battery, but not 'die'.
On one test, the battery icon claimed 15 minutes left to full charge, and I put the book to sleep (with a yellow glowing plug). Came back an hour or so later, the plug was still glowing yellow and the sleep light still on. Opened the book, and as soon as it awakened, the plug changed to green. Closed the book, and it survived the night just fine.
Any battery/charger/PMU gurus out there?

Any battery/charger/PMU gurus out there?
That machine would be about 16 months old? I have the identical machine, and it seems to me that (even before installing 10.2.8 - DON'T DO IT) the battery life was dwindling somewhat.
You could eliminate some problems if you could swap out the battery temporarily for another, that might rule out the power adaptor. Otherwise, it sounds like a new battery. However, judging by the screw up Apple seems to have made with 10.2.8, I'd wait till after Panther is released, beacuse the mutant code in 10.2.8 might still be lurking somewhere in the depths of the seeds of Panther.
