i got a problem with a customers laptop. he has brought it in with two batteries and both do not hold a charge.he told me that he bought it off somebody else and the person said the powerchip was not functioning correctly. i looked at apple website and other resources on ways to reset the powerchip memory and still no luck. is there something specific i need to do or could it be that both batteries are dead?
im fairly new to apple stuff and don't know where to really start. the laptop does detect the battery but strange thing is that up on top where the battery widget is, it keeps showing a battery sign with a "X" in it then it shows one with a charging sign in it.as if it was detecting then drops it then detects again.
the percentage stays at 0% all the time

Take the batteries to your nearest Apple Store.. ask them to confirm that the batteries can hold a charge or not.. Surely they can test it....if it fails, they will usually sell you what they got.

It's more likely the DC board in the powerbook is faulty, than two batteries.

May I just point out that there is no PowerBook G5. It would either be a PowerBook G4 or a MacBook Pro - could you please confirm which model it is?

Plus, is the machine in warranty? I could confirm this if you can provide the serial number (usually on a label in the battery compartment).

small typo.. BIG problem  ;-)

Okay, glad we sorted that one out. Can you find the serial number? It would make life a lot easier. Best way could be to start up the computer, choose About This Mac from the Apple menu (top left) and where it says the version number under Mac OS X, click here twice for the serial. Otherwise look inside the battery compartment.

doesn't need a firmware update
Irwin SantosComputer Integration Specialist

Commented:
can you run the firmware update even though it is stated? it may just refresh corrupt code..

if that fails.. then did you go out to apple and check out your batteries?

Cheers! I'm not sure if this guy is going to come back.

To test if the battery is charging, turn the laptop over and examine the lights on the battery - if one is flashing, the battery is receiving a charge. If not, no charge is being received. The diagnosis procedure would be as follows:

1) Try a known-good power adaptor to charge the battery, or try the adaptor on a different laptop to verify it's not working.

2) If you're sure the power adaptor is fine, test the battery in an alternative laptop that is known to be working (you've already tried an alternative battery in the same laptop).

3) If the battery is charging fine elsewhere, there is a problem with the DC circuitry on the logic board. The board will have to be replaced.

It should be as simple as that. The DC jack does get knocked quite often and it's possible the contacts have broken on the logic board. That's why the new MacBook has the magnetic DC jack so it comes away cleanly without breaking the most expensive component of the computer.

Not the solution you were looking for? Getting a personalized solution is easy.

With a four year old powerbook, my guess would be that both batteries are dead.  In my experience with powerbooks, 2 years is a good lifespan for a battery, with 1-1.5 years being typical.   If the customer needs a working battery, he can still purchase one from Apple, or buy a third party battery on the internet -  there are at least 3 or 4 third party powerbook battery vendors.

You're probably right. All I'm saying is that simply verfiying the battery won't charge on a single machine is by no means conclusive.

@didifool123....what's the story?

Author

Commented:
now the laptop doesn't even start. i think the dc jack is burnt now. and since i don't have a working battery it cant realy test to see if it charges.

any other ways of making it work or figuring out a the dc jacks.
Irwin SantosComputer Integration Specialist
Commented:
without a working a battery you're stuck...perhaps it may be prudent for you to take it in to an Apple store.

will they charge to check it out even if i don't have warranty?
Irwin SantosComputer Integration Specialist

Commented:
Can't tell you that..depends..if you know people in there.  Usually they'll charge you....but if you are cool about it..and say.."hey..I'm not sure if it is my battery or not... but if it is my battery, I would like to purchase one".  It's a simple thing to do if they have one available out in the open.
To repair a laptop, you can send it to Apple, and they will charge a fixed rate for whatever parts need to be replaced.  Depending on the vintage of the laptop and the extent of the problem, it may be more economical to get a used, working powerbook of comparable vintage and simply transplant the hard drive, and possibly the RAM, to the replacement machine.
