I hate my PowerBook's battery
I've been having lots of problems with my PowerBook's battery. At the last session, I had about 3:20 of battery life at the end of the session. After the session I found a table to sit at for 20 minutes. I plugged my PowerBook into a power strip.
When I got to the next session and turned on my PowerBook, I had only 2:30 of battery life left. Sigh.
