Hey all. My newly acquired Titanium PowerBook G4 is having battery issues. Well, I think so anyway. It hadn't really been used off battery in the six months or so before I bought it, and the battery informed me that it could run for three hours when I unplugged it. Yes, I let it calibrate to a realistic figure. Anyway, it's at 95% now with 3:42 left. I have brightness down all the way, just so the backlight is very weak. Last time I used this thing on battery, it went for a half an hour or so, saying it had about 85% left, and then went to sleep. Is this a calibration issue? I let it charge for three days, and now I'm back. Did I just calibrate it? Let me know, I really don't want to buy a new battery.
