    There are 4 components to the charging circuit ... the power adapter, the DC-in card, the battery, and the logic board. Unfortunately, there's no diagnostic that can tell you what's failing, so it's process of elimination to fix.

     

    Since you just said it's not charging, assume you're running on wall power, and the system sees the power adapter, so the power adapter is good. That also means the DC-in card is probably good. Do you have a spare battery you could substitute? Maybe see if your local Apple store happens to have one. If you determine it's not the battery, then you have a logic board issue, which can only be fixed by replacing the logic board, or only running the PowerBook on power. We had this issue on one of our PowerBooks, and it was fixed with a replacement logic board.

     

    One other thing you might try is resetting the PMU.

    Try resetting the PMU http://support.apple.com/kb/HT1431

    Yeah did that.  Already had a good read through similar posts.  Similarly to another user, the Powerbook had been replaced and I was only using it occasionaly for certain aps I haven't yet updated.  So a month could go by with no use.  Meanwhile the battery seems to have died.  i can continue using it with the power cord in, but the internal date and time keeps resetting to 1970.

    I'll try taking it to an Apple Store, but I don't want to spend any money as eventually I'll upgrade this to a new desk-top.  (currently managing with a macbook air)

    The date resetting means your internal PRAM battery needs replacing.  Finding a replacement is challenging. If your 1.67Ghz is a 17" model, however, OWC has a replacement here.

    It's a 15" 

     

    I'll check out how to replace before I part with the money!
