Hi everyone,
I have a relatively new battery for my Powerbook G4 Titanium computer. I have been very diligent at letting it run nearly fully down before recharding the battery again. However, I have noticed lately that when the battery indicator in the menu bar gets to approximately 15%, the computer automatically goes into sleep mode and I need to plug it in again.
Is there somewhere I can reset the battery or fix this problem?

Sounds like you need to (re-)calibrate your battery against your computer. The battery has a chip which "tells" it how full it is; the Power Manager in your computer does the same. These two need to be "in sync". To do this, you have to "make them know" which charge level in your specific battery constitutes "full" and which does "empty".
See http://docs.info.apple.com/article.html?artnum=86284 for Apple's official advice on how to do this.
FWIW, I recalibrate my two batteries about once every three months.
