When the iBook's battery is charging, is there a light that's supposed to be showing somewhere? I thought I'd read that some part of the wire spool, or something else glowed when the battery is charging (possibly I'm confusing this with the TiBook?). Just curious. I've noticed durations of only about 2.5 - 3.5 hours between charges (out of the reported 5 hours claimed by Apple); but other than that, I don't really have any concerns with my machine. I just love it.
