MBP battery dying

[Joel Beason]

I have a year old macbook pro, I have had it for a while and always watch my battery. I noticed it died a little faster then normal (i never let it get to below 20%) today I unplugged it and it said I have 41 minutes at 100% Im using it now, 15 mins later it is now at 60% and falling fast. I installed leopard and the computer runs warmer, and the fans run, more then they ever have is that the reason or is my battery just dieing, is there anything I can do to fix this???

You say you never let it go below 20%...I assume that means you never calibrate your battery (http://docs.info.apple.com/article.html?artnum=86284). Try that and see if there's any change.
