hi, the problem is that my ibook battery (that is suposed to last 6 hours) is lasting a little more than 4 hours... is any way that I can recalibrate it, or I have to buy a new one??.... Does anybody have the same problem???? thanxsss

Leave it on until the battery completely drains (run F@H or SETI, that should speed things up). Then charge it up and don't interrupt it until it reaches as close to 100% as possible.

You should be able to get UP TO 6 hours on a single charge, depending on how you use the iBook. There's information about how to configure your system for best battery life HERE Apple will tell you that more than 1 hour life should mean that your battery is OK.

I think 4 hours with full-bright screen and regular work is quite good.

On my Powerbook, I'd be lucky to get 3.5 hours on a full charge with full screen brightness. Reduce the brightness by half and I get around 4 - 4.5 hours.
