    Hi all,

    I thought my iBook battery was messed up because it only tends to lastt 30 mins if im lucky, and my power seetings are tuned!

    But then I got Coconut and checked my battery capacity and it says its 89%, how does that work? why does my iBook go to sleep so fast?

    Apparently its had 120 loadcycles (its 2nd hand btw), any ideas what going on here?

    Title - i don't know erally, my battery is in an ibook, its acting a bit unusually, perhaps mentally.

    I mean it was on 84% battery, then the computer went into sleep mode, then i plugged it into the wall and it displayed 0% battery. is that understandable now?

    Sounds like a failing battery but hopefully I'm wrong. Have you calibrated it recently? :)

    "calibrate", well i often charge it up and then unplug it, at which point it dies anywhere between 85 and 70%, is that calibrating it?

    Should I reset the PRAM or the PMU before trying to recalibrate it?

    or am I fighting a loosing battle here and should consider a 3rd party battery off ebay?

    Yeah, the PMU reset may help, but it's doubtful. It really is just sounding like a failing battery. :eek:
