Weird Powerbook battery issue

Powerbook G4 1.67GHz - from what I can tell, battery is not part of the recall.Coconut battery shows the age as 2 years, with only 37 cycles, 96% capacity. I'm not sure if this is a newer battery or original. I just received the laptop a few days ago.

The powerbook works great on AC power. When I unplug the AC cord, the screen goes off, but the laptop is still on. When I plug the AC power back in, the backlight comes on, but there is no display. I have to hold the power button down several seconds until the laptop shuts off.

If I try to turn the powerbook on strictly using battery power, the fan and hard drive spin, but the monitor does not come on. The white light on the front also stays lit. I have reset the PMU and whatever the other thing is Apple's site mentions.

Right now, I have it running on battery power, waiting on it to completely die. The hard drive and fan is spinning, but no display.

Any ideas?
 
If it's still under warranty, I'd take it in to an apple store or authorized service provider. It sounds like kind of an odd mix of problems- *maybe* having something to do with the inverter, maybe the switch that tells the computer whether the screen is open or closed...not sure why the fans would be staying on the entire time though, so it may be something completely different.
