I noticed something weird whenever I'd charge the iBook and leave the adaptor on. The battery meter either doesn't reach 100%, or it does, then falls down to 99-97% and it stays like that indefinitely. I'm just wondering if this is normal, or is there something wrong with my battery? Also, when I press the battery light meter it says it's fully charged; all four light's glow. Hmmm, just wondering if anyone could shed light on this matter. Thanks!
