    macbook 820-00165 ppbus short

    hello

    i've just got a macbook air 820-00165 motherboard.
    ppbus_g3h is short du to c7313, a tantalum 62uf 11v capacitor.

    my problem is that i haven't got any capacitor like this.

    can i leave c7313 empty as there is many many capacitor on g3hot line ?

    thank you

    Yes, you can. Leave it off.

    Just repaired the same board a few minutes ago. SMC reset was stuck low. The board was filthy and the the SMC reset line was ~200 ohms to ground and with an output of 0v2 instead of 3v42.

    After dousing with IPA and cleaning up the reset supervisor - unit is back and working again. Came in with a fake charger and no green / amber light.
