    A2179 820-01958. Powering on, not charging.

    I had a unit come in yesterday. A2179. No power, not charging. 5V on both USB-C ports, U3200 was getting hot, while U3100 apeared normal. No liquid damage at all. I went ahead and replaced U3200. Still not powering on. 5V and voltage fluctuates and then settles at 0.192A on both ports. I...

    820-00840 Stuck at 5V

    Hi there. This Macbook came in with no power. Stuck at 5V on both USB-C ports and hovers between 40mA and 26mA, never gets to 20V. . I believe it was a cheap power cable that caused this. Board is 820-00840. PPBUS_G3H is missing, all other necessary voltages appear to be present. There are no...

Board will not power up fully on charger with battery connected (fan spin for 3 seconds then power off) Zero signs of liquid or corrosion on board. Will boot with battery AND charger connected, but will not...

    A1706 (2016) 820-00923 Power button not working.

    Thank you. Unfortunately today the board decided it wont power up at all. It goes from 5V to 20V - 0A and just stays there. SMC_RESET_L is 3.4V. This is with the board out of the unit, bare. I have tried all four ports with same result. No shorts on SMBUS_SMC_5_G3H_SDA or SMBUS_SMC_5_G3H_SCL...
