    Hi all.

    I have MBP 15" A1226
    No sound - in settings in only DIGITAL OUT, volume bar is grey, wont respond on volume buttons

    Second problem: showing SERVICE BATTERY, I swaped battery from another A1226 and problem is still the same...

    Whats wrong?
    I/O board?

    Thanks for help

    I would try the IO board if you have another machine handy you can swap with.
