    820-02536 no keyboard/trackpad

    all seem good and have good connections but RT365 and RT366 are measuring 9.3k (should be 47k). SPI_IPD_MOSI is 0.284 (0.330 on openboard reference).

    UT360 was shorted. After replacing i get 3.3v on PP3V3_S2SW_IPD_F. PP5V_S2_IPD_F, IPD_LID_OPEN_1V8, PPBUS_AONSW_IPD_F are present. (measured on JT400) Still no keyboard or TP Tried different TP flex cable, no change.

    820-02536 no keyboard/trackpad

    Supposedly keyboard and trackpad stopped working after LCD replacement, but angle sensor works good and its oem. PP3V3_S2SW_IPD_F is shorted. I am unsure as to how much voltage to inject since its first time working with this model.

    820-02773 boot loop

    PPDCIN_USBC_AON does the same but loops faster. PPBUS_AON starts at 12.2v. Goes down to 8v and then 5v when shutting down. I replaced U5200 just in case. No change.

    I noticed sometimes it went into de OS. DFU did nothing. PPDCIN_USBC_AON goes to 0v when it shuts down, then to 5v an then 20v. PPBUS_AON starts at 10v and then goes down to 9v when loading OS. When shutting down it goes to 5v
