  • 820-3536 Not working off the battery

    Hi Guys i'm working on a 820-3536 board. Unit works with charger only, it sees the battery, it charges the battery, but when i disconnect the charger the unit cuts off. The 10ohm resistor is also good. Does anyone know what else the problem could be?

    Was this liquid? Check if 3V42 is present with battery only.

        Liquid where? I suspect crap under SMC or a corroded pull up resistor around it.
