Tech Info Article 14449: Power Manager ResetFrom what it sounds like, you were resetting the Power Manager on the Duo correctly.
The short tune, did it sound like 8 distinctively different notes played, sounding like it came from a n electronic piano (kind of electronicy)? If so, that is called the Chimes of Doom. It is a signification that there is something seriously wrong with your Powerbook.
You also mentioned the battery losing charge very quickly. This is a sign that regardless of Power Management reset, the battery is dead.
Fix tips: First off, leave the battery out of it overnight and put the battery in and let it charge again over the next night. Try starting up with the power adapter still plugged in. You may want to try restarting a few times if you continue to get the chimes.
If you are at least getting a startup chime or chimes of doom, then you are not completely dead. If you have no tones but the screen comes on, the RAM/motherboard/processor/hard drive could be dead (Happened to my 180c).
