Hello, Awhile, ago i put a post up about my iBook G4 not working, due to the little gears just kept spinning on startup, so i have now fixed that, whohohoho! So, it's been about a year since my iBook has worked properly, and now i'm having trouble with my battery. The iBook seems to be turning off, after only using 25% of the battery. This means the battery has 75% still left. Also, it's giving me no warning that it's going too turn off it just does. I looked at Calibrating the battery, but i don't think i can do that as the iBook is not actually using all the battery life. Any suggestions?
