    [SOLVED]Battery is not recognized 820-4942-B

    I think you have two separate issues here. First fix the system side current sensing because 5 ohms is a bit high, and that should hopefully fix the issue with the charger light turning off. Then post the voltage on PPBUS_G3H and on either side of R5380/1.

    Diode mode measurements are the same as measuring resistance. You CANNOT have a charger plugged in when you are measuring a voltage drop!! STOP!!!

    820-3115 no pp5v_s5/pp3v3_s5

    That's not an answer. Is the enable present, low, or non-existent?

    [SOLVED]2016 12 inch schematics available?

    Yes, I have seen them on the vietnamese forums. And no, I'm not going to give you a direct link on a public forum.

    You can't measure resistance when there is power in a circuit, that's how you blow a multimeter up. Read the sticky first: https://www.rossmanngroup.com/boards...71-forum-rules Determine if PP3V42_G3H is present on U6901.

    How do you tell which are fake once you receive them?

    820-2936 no PPBUS_G3H

    You have no green light. First, PP3V42_G3H present on U6901?

    820-3437 no led

    No, you should find out if SMC_RESET_L is high or low.

    [SOLVED]820-3115-b , green light, does not turn on , P3V3S5_EN_L missing

    Sorry to hijack this, but question about the _L thing: Isn't PM_SLP_S4_L supposed to be high? Is it just a misnomer?

    [SOLVED]820-3437 Fucked SMC?

    I actually just had a 3437 that was failing all the temperature sensors like that too, and it ended up just being the trackpad flex that was causing all the sensors to fail. I suspect it was causing those SMC data lines to be pulled low. Cool story bro.

    [SOLVED]820-3787 No Image

    If you have GPUVCORE_EN, then remove L9330 and L9360 and then inject 1v onto PPVCORE_S0_GFX_REG with a power supply and see if it works, if not then fucked.
