I've a similar problem (that almost cost me my sanity a few minutes ago when my powerbook3400 wouldn't boot up, the very same pb that contained my very important project to be handed in tomorrow)
Basically, if I disconnect it from the ac adapter and put it to sleep or wake it up, it won't wake up properly - it's hard to describe, but the sounds aren't right, I don't see a cursor in terminal windows (yet I can ls and do some stuff), and if I try to reboot or halt, there's the loudest beep in the world until I press ctrl-cmd-power.. and then it doesn't always boot back up (like today, it only wanted to boot from a CD, not the hard drive... and then it wouldn't even boot up, until I pressed the little reset button at the back for like 15 seconds...)
