My son has taken on the challenge of a PowerBook 230. It works fine in the docking station, but outside of it it is dead. Any ideas would be appreciated. Was leaning towards a problem on the logic board.

Also, on the logic board there are 2 items that are to the left of the CPU. They look like a coil of some type and are marked with AT&T on them. Anyone know what they are, one is cracked up and needs to be replaced.

Thanks,

Ed

Try this Apple Manuals page http://support.info.apple.com/info.apple.com/manuals/manuals.taf?view=browse&search=category&string=powerbook&start=1 .

You can download any or all. Might help.

hmmm...he needs the Service Source file for that machine. That will get him started.

sounds like a power manager reset MAY make it behave outside of the dock, but it could also be an issue where the power connectors inside the battery bay do not correctly line up with the leads on the battery....or you could just have dead batteries. Or are you saying it refuses to work with a power adapter? You need to check the solder joints on the power connector, as well.....put a multimeter on your power supply and see if it lives.....you probably need to replace the lithium battery under the trackpad, too.

they are cool units, but they are getting tough to restore....a lot like restoring old cars.

let's see if anyone has a lead on a Service Source file for you. We can't send you one. Apple would sue us.

What is the service source file? Also he has attempted to use the power adapter. I believe it to be good, will double check it. What are the two coil objects marked AT&T? One of these has the outer grey frame cracked and broken.

Thanks

I think the items you describe are transformers of some sort to power the unit. If being broke is the problem, you are going to have to get a new motherboard (those are cheap) or try your hand at SMT soldering.

Does the unit work on a AC adapter ?

No, only in the docking station and it works fine. My son took it apart to fix a keyboard problem and I guess did something because it worked fine, except keyboard, before.

Do you know where I can get the transformers?

Unfortunately I am not familiar with the transformers. It might be cheaper to buy a whole motherboard (~$10) on ebay.

On the other hand, if you can find a dead duo motherboard that similar transformers you might be able to transplant one. Can you read a part# on the transformer ? I have a dead mobo or two I can check for similar parts....
