d'oh! powerbook battery question

[Musicfuelzgood]

okay so i have a quick question....SOMEHOW...i left my powerbook on without having it plugged in overnight...in the morning...i looked at it..and it said 0% and only powered up with the adapter plugged in. now it works fine with the adapter...but the battery isn't charging....is there anything i can do? i tried resetting the power manager, and that seemed to work once...but now it's back to 0% again for some reason...any help is greatly appreciated. i've searched apple...bummer

hope you bought apple care?

did you check the battery its self. there is a littlebutton on it push it in. dose it light up the leds above it? i had my power book mis read battery power before but it was usually only for a few minutes before it corrected itself

no apple care here. but thats neither here nor there...the computer works fine with the adapter...but is not really a laptop..since its not portable...when i click the little button on the battery the first LED blinks a bunch...thats about it...then occasionally it will read 4 lights.....anyone else have any info on how to recharge the battery correctly? because it's been at 0% for a while now. i'd like to know before i shell out some cash for a new battery.

bump!.......this has never happened to anyone on here? the apple support page online is offering no support whatsoever.

how old is the battery? some rechargables don't like being drained completely. others like to be fully discharged before charging (keeps them from developing a "memory"). depends on the chemical formulation of the battery, i think.

if the laptop has been plugged in for several hours, and you unplug the ac adaptor, does the computer shut down?

tried removing the batt & re-inserting it?

zap pram (can you still do this in os x?)

just a couple of ideas that come to mind.

thanks for the reply man...i really appreciate it. if the computer is on...and i take the adapter out..the computer goes into sleep mode. sometimes it'll show 100% ..sometimes it'll show 0%....mostly 0%....i tried removing the battery and power cord...and holding down the power button for 5 seconds....didn't really do anything.....it just goes back to 0% a lot...and then doesnt charge...but then sometimes will go to 100% and then once i put the adapter...it goes to 0%...very strange...any other tips would be appreciated....right now its working with the battery...but i know once i put the adapter in...it'll maybe work off adapter and switch the battery to 0%...the battery overall is acting weird....just like this post....last bit of info...the battery is the one from the 15" powerbook titanium model. thanks guys i appreciate it.

got a friend w/ the same batt that would let you stick it in your machine? methinks it the battery, but could be the regulator/control/detector circuitry built into the powerbook.

don't know what to tell you... sorry to hear about it.

hey, actually... weren't there a bunch of recalls on powerbooks in the last year or so? something with the batteries. you might look into that.
