    after doing a diy gpu reflow on my 800mhz ibook g3 (a success) the built in keyboard has been acting erratically or sometimes not at all

    Did you make sure to reconnect the keyboard ribbon cable completely? If so, is one of your coins shorting out the underside of the keyboard perhaps?

    the ribbon cable is plugged in propley - i checked several times
    and the coins stopped working so i did a diy reflow using a heat gun (fixed the gpu) this is when the problem started
    haven't tried that yet will try in the morning

    You're probably shorting something out/melted something associated with the keyboard with the heat gunning. =\

    You could have reflowed one of the keyboard connectors on the logic board into another one. Did you use a shield when you gunned it (congrats on that working, BTW)?

    High five getting it fixed! My 900mhz iBook had the graphics issue and I heatgunned it and ended up killing it completely haha.

    Al foil isn't exactly the best insulator...in fact is conducts very well and has a low thermal capacity. (Hence why you can grab a sheet of Al foil straight out of the oven and not burn yourself)

    Chances are it didn't shield very well...

    Double check for dust in the connectors and I once used a blowdryer on a disconnected iBook G3 keyboard and it fried the thing. Not that much heat wrecked it. You may just need a new keyboard.
