    I2C_PWR_SDA - 420 I2C_PWR_SCL - 420 SMBUS_3V3_BATT_SDA - 830 SMBUS_3V3_BATT_SCL - 860 PP3V3_G3H_RTC_X - 347 Not sure how I got those measurements but the data cable was unplugged, only the big screw was on the battery for the power line, so that might have been it . Here are the correct ones

    Diode mode readings: I2C_PWR_SDA - 208 I2C_PWR_SCL - 208 SMBUS_3V3_BATT_SDA - 208 SMBUS_3V3_BATT_SDA - 208 When I measure any point the multimeter makes a clicking sound repeating every second :unsure: The measurements are without U6902 for both voltages and Diode mode

    In battery health, it shows service recommended and shows fully charged, and I tried 2 new batteries. The old one was inflated.

    I thought so :LOL: U6920 it's the protection diode , which I replaced, but I can remove it and try. I'll revert soon

    Hi. I have this A1990 with the battery not being recognized properly. SMBUS_3V3_BATT_SCL is 1.2v, and all others are fine around Q6950. I also have PP1V8_SLPS2R. I replaced Q6950 and U6950 to make sure nothing was going on there, and I resoldered the battery board connector to make sure all...

    Yes, I checked the standby sequence and checked all surrounding components all measure fine, searching for a spare U5700 from a board. I will update once I replace it

    I replaced U5200 and now it's the same range. I will re measure again U5700

    Yes 4v, and it was 11.9 up to 12.2 fluctuating. I'm suspecting U5200 has something to do with it

    PPBUS_AON is present and goes from 11.9 up to 12.2v. Diode mode reading is 455 on F5200

    Hi guys. I have this board with no power stuck at 5v 0.55amps and small fluctuations on the side of the amps. On the thermal camera, U5200 pulses. No short on U5200 and surrounding components, no liquid spill, and no voltages going to the PMU U8100. Would appreciate your help on this. Thanks
