Can I bypass thunderbolt Area since originally it was burnt, definitely something is short in that area but I couldn't figure out

I did trigger R5115 by Shorting both points I checked all Pins on C3210 nothing is low on resistance rest of the board in Mint condition, didn't find any short on power rails in thunderbold area

Hi I got a 820-00165 Motherboard for No Power U3210 was burnt badly from top So I replaced it also C3285 and C3286 had Liquid Damage, Both replaced. Still board is not powering up Missing PP5V_S4rS3 PP3v3_S5 is 3.32V Don't know where to start now

R/C7125 are Good. After Replacing Q7130 Problem Solved, I got nice 12.54V and Solid Light on Charger with Battery Thank You So Much Problem Solved

PPBUS_G3H voltage with charger only (no battery) 20V which should be around 12.4V Resistance between pins 17/18 is 4.3 Ohm and 27/28 is 21Ohm of U7100.

Hi I have Motherboard 820-3476, Board is working fine with battery or Direct with charger but If battery is connected then it's start blinking like cutting of power. Replaced U7100 ISL6259, Checked R5380,R5381, No Corrosion so far. Any Suggestions

C7090 was culprit, it was 100 ohm on diode mode and I didn't know it's bad. Sorry I didn't mention value on that Cap earlier. Issue is solved and Board works like charm. Thanks again for all your Help @2informaticos 5*

Thanks for Help On diode mode at L7095 no short to ground (it does not beep when I try to connect probe to ground) Removed U7090 from Board, still new resistor blow out without it. R7096 is about 181K R7095 is about 360k PPVIN_G3H_P3V42G3H is 0.65v with broken resistor and components removed.

Hi I have 820-3437 Logic Board As soon as I plugged charger to this Board, R7005 Blow out. R7005 not short to Ground. I tested with New R7005 without D7005 it gives me roughly 20v on both ends. As soon I Install D7005 , R7005 blows out. NO sign of Liquid damage on motherboard. PPBus_G3H is...

Still waiting for if someone want to help me here ?
