    MacBook Pro M4 A3403 EMC 8895 Water damaged cap missing | No schematics and board view available

    First of all, welcome to the forum! If the machine works correctly (without the keyboard) that is probably a filter capacitor. May not be critical in such case and you can let it as is. BTW, what is the IC on the opposite side of the mainboard?

    820-02016 A2337 - Battery not detect

    Pad 1 of R5150 and pin 5 of J5150 are connected together; both MUST have 0V.

    820-02841 - Keyboard and shutdown issues after liquid damage

    "2V looks too low for PBUS_VSNS_OUT; it should be close to 12.5V. You should get 1.33V aprox at PBUS_VSENSE." Pay atention when you read... 1.27V looks close enough. You may have problem with another sensor; check them all.

    820-02016 A2337 - Battery not detect

    "SYS_DETECT_L : 3.28V after replace UD201 ............................. SYS_DETECT_L : 0V" When I should believe you? "i have 3.2V on pin 5 J5150 only whith battery connected" It must be always 0V; make permanent short on R5150 pads.

    What is SYS_DETECT level now? You can test the machine shorting R5150 pads.

    A1466 820-00165 Pulsing S5_PWR_EN after lots of corrosion

    PPBUS_G3H pulsing too? Just in case, bypass F7140 with an wire for test purpose.

    820-02016 A2337 - Battery not detect

    SYS_DETECT_L must be 0V. You should get high level at SYS_DETECT only.

    820-02841 - Keyboard and shutdown issues after liquid damage

    Yeah, looks good now. What is PBUS_VSENSE (CD520) voltage?
  20. 2informaticos

    820-03285 no keyboard no trackpad

    Post U5200 basic voltages: P_IN, AUX_DET, SMC_RST_IN, VDDA/P, EN_MVR, AUX_OK, A/BMON.
