    820-00164 ppbus_g3h = 0.918v

    PPBUS_G3H = 0.918V Fan spin if battery is connected. Found r7121/22 bad resistors. Replaced r7121/22, c7121/22, c7120, isl6259 What should I check next? Thanks.

    820-00165 green/orange light ok / no power

    Trigerred SMC_ONOFF_L about 20 times. Multimeter didn't catch any pulse at PM_SLP_S4/3_L.

    820-00165 green/orange light ok / no power

    PM_PWRBTN_L drops to 0.360v PM_SLP_S4/3_L no pulse (don't have o-scope at the moment) It won't turn on in SMC bypass mode.

    820-00165 No PP5V_S4RS3, green/orange light OK

    Board looks very clean (only small amount of flux near smc). Forgot to mention that at first there was no light on charger because of bad flex cable (reason for smc reflow). SPI resistor and traces looks fine. When trying to bypass smc fan starts to spin for a few seconds.

    820-00165 No PP5V_S4RS3, green/orange light OK

    No liquid damage. Before me someone tried to reflow smc PP5V_S4RS3 pulses 2 times then stops. PPBUS = 8.6V G3H = 3.42V PPVRTC = 3.3V 5V_S5 = 5V 3V3_S5 = 3.3V 3V3_SUS = 3.3V

    820-00165 won't turn on if IO cable is connected.

    Thank you guys. Works as it should it genuine charger. Can someone explain why it won't turn on with power supply(cable is from genuine 85w charger)

    820-00165 won't turn on if IO cable is connected.

    820-00165 won't turn on if IO cable is connected. Had liquid damage around smc and few shorted PPBUS_S5_HS_COMUTING_ISNS CAPS. After cleaning liquid damage and replacing caps now only turn ons if IO cable isn't connected/. If IO cable connected orange light is there.
