    I have a Powerbook G3 Lombard that has been having a keyboard issue. Certain keys don't work, like the arrow keys and caps lock and some others. I have a new keyboard that I am going to install, but I don't know if it's going to work. Is there anything else this could be?

    Dust? A broken spring?

    I have seen some repair pages about USB :apple: keyboards. Maybe you can find some specific info on ifixit or xlr8 about your Powerbook disassemble.

    I have a blue usb :apple: keyb that no one key works from "C" to "M". Disasembling them always broke some little plastic I even saw somewhere a guy that repaired a broken track of the circuit with a chocolate plate! :p

    You could try cleaning the keyboard's flex connector using a pencil eraser. I've fixed several laptop keyboards by doing this.

    I installed the new used keyboard and now caps lock works, and the left and right arrows work, but up and down and certain letters don't. Could I be having a problem with the KB connector not seating correctly?

    Try this:

    I've taken apart my PowerBook G3 Lombard countless times for no reason, I always ran into problems reconnecting the keyboard and trackpad, try making sure that the connections line up and push down until you hear a pop.
