    macbook pro A1707 board 820-00281-A

    Hello

    I'm trying to repair as best I can my macbook pro which suddenly turned off even though there was nothing plugged in and I wasn't touching it. I noted several voltages or not, I'll indicate them to you below if you have any ideas I am very interested thank you in advance

    PP3V3_SUS ok 3.3V
    PP3V3_S5 ok 3.3V
    PP3V0_G3H ok 3V
    PP5V_PMICLDO ok 5V
    PP3V3_S5 ok 3.3V

    PP1V0_SUS no 0V 57hom
    PP1V8_SUS no 0V
    PP3V3_S0 no 0V
    PP5V_S4 no 0V

    The consumption of the Mac is 0.014A and 20V so the USB chips work

    looking at the diagram I think that I can simply bridge the two pins 1 and 2 because I do not have the second component to solder on my original motherboard after that I do not know the functionality of this component

    Thank you again in advance for your help and for reading me
    ps: sorry again for my bad english
