iBook battery mentalness?

[tektonnic]

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?

infact, at 84% my computer just went to sleep and now ive plugged it in its on 0%!!

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?

 

[tektonnic]

"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.
