Help please, macbook doesn’t power on if charger is not present? Works on battery and charges battery and turns on if charger is present

Here is small picture bcs whole can't upload

Image whole screen goes wild

Hi, I replaced D7105 that diode was problem after replacing device is charging and working normal on battery. Device works normal and out of the blue screen starts to flicker sometimes, I reflowed connector inside the screen and I didn't get that problem again for now, I tried to post the...

I found a short on D7105 after replacing there is still some problem

When I come home from work I will measure resistance on u7100 and post it back

I have short it doesn't turn on if q7130 is not burned I have 0 V PPBUS_G3H

I replaced what you said, q7130 didnt blow yet and when it blows device will work, now its short circuit somewhere but nothing even close to 0 ohm, what to do next i replaced u7100 and q7130 tested all leads all over chip is 0.300 or more no short

Where should I start troubleshooting?

q7130 is shorted on leads 2 PPDCIN_G3H_CHGR 7 CHGR_PHASE itsshort on all 3 of them did i blew up all of them?

Those are voltage drop readings on diode mode without any power

I will post measurments on board, q7155 was shorted, after swapping it device is telling to plug the charger for the first time. On 1 PPVBAT_G3H_CHGR_R - steady 20 V 5 PPVBAT_G3H_CONN - withouth battery no reading Reading on board when q7130 off board 2 PPDCIN_G3H_CHGR 0.590 7...

READINGS ON BOARD WITH Q7130 OFF BOARD: 2 PPDCIN_G3H_CHGR 0.590 7 CHGR_PHASE grows from 0.100 to 0.420 steady

CHGR_Phase and PPDCIN_G3H_CHGR is shorted on q7130 on all 3 that i have 2 PPDCIN_G3H_CHGR when i measure with q7130 removed voltage drop is 0.574 7 CHGR_PHASE voltage drope wthout q7130 is 0.410 I replaced u7100 and q7155 and removed q7130, didn't turn on board yet bcs i'm not sure if q7130...

Whats the voltage drop if q7130 is half faulty and if is good
