This is well-known problem. It is a specific cable that needs to be
replaced. The cable is just about 10 bucks but it rquires taking apart
almost the entire iBook - nothing I'd be too keen on doing.
You might send it in to an authoirsed Apple dealer that does repairs like
tihs. As far as I remember,
www.smalldog.com offers such a repair for
something like 79 dollars. Perhaps you'd like to check out their website.
I recall to have seen this repair as a standard repair there (if you are
in the US).
Hope this helps.
