Don't have a the DFU Recovery Tool, lol PP5VG3S_EN - Do you think this needs to be present for DFU revive to work? Because it is looping at 20V, 100mA, can you think of anything else that could cause it to reset the PP3V3_G3H, except for the PMU?

So not sure if we will be able to get help on this. But I thought I might as well ask hoping for some ideas on how best to proceed. 1. Logic Board came in for Data Recovery due to Liquid Damage 2. Most Power & Data Lines were repaired, found shorting on CPU 3. We have now successfully replaced...

C7140 voltage fluctuate 4 to 6v. U7100: 1-0v, 2-19.86v, 3-4.67v, 9-0v, 12-3.4v, 13-3.3v, 14-3.3v, 15-4.0v, 17-6v, 19-5.4, 20-5.4, 27-19.5v.

i have fixed it all. now facing voltage fluctuation from 12 to 9v on PPBUS_G3H(diode-0.125) line.

i am getting 0.129 diode value after removing all that resister and capacitor and also U7100. might be this issue. it should require OL on pin 19.

yes, you are right. is there any else which generate voltage on u7100 pin 19, because i have removed R7191, R7101, C7101, C7100. then checked voltage on pin 19, i am getting 6.7 to 6.9 voltage still. and i have fixed U7100 from working board-in that board on pin 19 it hase 5.01 voltage.

I HAVE REMOVED R7191 THEN AFTER GETTING 6.8 TO 7 VOLT, FROM U7190 5 VOLT OK, AFTER REMOVING R7191 I AM GETTING 5 V ON L7195 OK.

I AM GETTING 6.8V ON PP5V1_CHGR_VDD . AND ALSO THAT PIN GET HOT COMPARE TO ANOTHER PIN. DIODE VALUE PIN 19- 0.418 PIN 20- 0.419

no.. voltage 1.85 ok.

with 50k, voltage 1.85 ok on PP1V85_S2_IPD. keyboard and trackpad work 10 to 15 minute then not work..

Spare not available..can i bypass it ?

No...stay high. 1.8volt

Yes tried all 4 tries, not working, and i am getting 1.8 volt on UPC0_ATCRTMR01_PWR_EN & UPC1_ATCRTMR01_PWR_EN. and before i am getting 3.3 volt on pin 6 of UF790 (ATC01_VDDCIO_VR_EN). but now no any output on pin 6,7,8 on UF790. external mouse and keyboard working fine.

i have removed CT304 , then tested same occur..1V85_S2_IPD in this line voltage come and then gone(1.85v).. now also IPD_P1V8_PWR_EN_RC voltage come and gone(1.8V).
