    I have a g4 iBook logic board that is completely unresponsive.

    I can see no physical damage to the board.

    I believe he problem is not the dc-in board because (1) I get a green light with no battery attached and an orange one when a battery is charging; and (2) it behaves the same way with two different dc-in boards.

    Neither of two power buttons nor jumpering the pins will get a response from the board.

    What else is there to try? I hate to recycle it if I can get some more mileage out of it.

    Thanks for whatever help you can give.
