    820-00165 Missing S4_PWR_EN, PM_SLP_S4_L Missing

    PM_SLP_S3_L is 0V but when I trigger SMC_ONOFF_L it pulses to 3.3V PP3V3_S3, PP3V3_S0, PP1V8_S3, PP1V2_S3 all 0V but do pulse when I trigger SMC_ONOFF_L

    820-00165 Missing S4_PWR_EN, PM_SLP_S4_L Missing

    I do get a pulse on PM_SLP_S4_L when I trigger SMC_ONOFF_L, bypass same thing. One thing I noticed is that PM_SLP_S4_L and S4_PWR_EN pulses once at the correct voltage right after I connect charger.

    Board had a little bit of corrosion around C2952 and PP3V3_S4 was shorted (C2952 and U8000) both replaced but I am missing PM_SLP_S4_L and S4_PWR_EN is only 0.310V PM_SLP_S4_L Diode 0.474 SMC_S5_PWRGD_VIN Present PPVRTC_G3H Present U1950 Pin 8 has 3.4V

    820-01987 20v No USB Activity

    I thought I had checked R7744/7 but they were off a little bit, replaced them and checked, but same thing. Checked with board alone even with no LCD flex cable connected (also checked the FPC and all good) but same thing.

    820-01987 20v No USB Activity

    Clean board, came with shorted U7710 and U8500 now I get 20V and 0.200A after a few seconds, I do get USB 5V but no activity. Restoring T2 takes a long time and eventually I get lock icon. Trackpad clicks but there is not light on caps lock. Battery was discharged and overnight it got charged...

    820-01700 Wont charge 5V 0.280A without battery 20V with battery.

    Ok now I do have 20V in all ports without battery connected, I do have usb voltage and activity on left side, however on right side only UB300 has voltage and no activity, UB400 has none, I have already replaced UB000, UB090 with correct firmware, UB700, QB701, U8285, YB200, DB503 and both...

    820-01700 Wont charge 5V 0.280A without battery 20V with battery.

    In its case board does indeed still boots fully, 20V with battery connected but wont charge. Left side has USB voltage and activity, right side is missing both, this gives me something to look for. With battery alone no trackpad I still dont get voltage on those 2 coils (remember this board...

    820-01700 Wont charge 5V 0.280A without battery 20V with battery.

    I will install it into its case again and test, but it only boots with battery connected.

    820-01700 Wont charge 5V 0.280A without battery 20V with battery.

    Ok I have P5V_G3S missing and U3500 needs that in order to work, when I check U7650 I see that P5VG3S_EN_R missing, following that P5VG3S_EN is missing too as well as PMU_PVDDMAIN_EN and that only comes out of PMU, all AWAKE and SLPS2R signals are present, so far this is what I got, would that...

    820-01700 Wont charge 5V 0.280A without battery 20V with battery.

    R5246 ok J3300 and JB500 are on par with known good board in diode mode Mac only has USB activity in bottom left port (the one used for restoring) the other ports dont have voltage nor activity

    820-01700 Wont charge 5V 0.280A without battery 20V with battery.

    Diode read on UPC_I2C_INT_L is on par with know good. Checked for shorts around all CD3217s and all is fine, I have had this board for a while now and I am ready to give up unless you think I should check something else.

    820-01700 Wont charge 5V 0.280A without battery 20V with battery.

    Yes 96W charger used. All 4 CD3217 were replaced from same donor board that had 20V Already replaced from donor board U2890 and UB090 UPC_I2C_INT_L is 0V Diode 426 with board alone Just in case I2C_PWR_SDA/SLC 1.8V with correct Diode read Diode and voltages PP3V3_G3H_RTC_X 3.3V 460 Diode...

    820-01700 Wont charge 5V 0.280A without battery 20V with battery.

    Sorry for the lack in information, this Mac boots fully with charged battery and I get 20V with battery installed but 0A so it wont charge, board alone takes 5V and 0.280A, T2 revive works all the way to the end but no change. I dont even know where to start, but I just replaced U7000 and same...
