    820-00165 Missing PM_SLP_S4_L

    I am working on the a MBA 13 2017 no signs of water damages. First has no green lights on the MagSafe charger I replaced the SMC I have a green light but missing PM_SLP_S4_L. I measured voltage on U6100 at Pin

    U6100 Chip.

    1. 0.701v
    2. 0.283v
    3. 0.112v
    4. gnd
    5. 0.204v
    6. 0.284v
    7. 0.104v
    8. 0.101v

    Missing PP3V3_Sus at U6100 at U8020 PIN 6 missing PP3V3SUS_EN. PP3V3SUS_En is coming from the PCH. I don't know where to start because the board has no signs of anything of corrosion or component burnt out.

    Updates: These MBA 13" 2017 won't turn on when everything is un-plug not like the 2013-2015 model turn on automatic when you plug the MagSafe adapter. LMAO! Everything is working now. SMC replacement and R1270 and R1275 ultrasonic plug in everything and Voila turn on.

    Hi, so what did you plug into the board to get it to turn on?
