This was working off battery only but wouldn't charge. Looked like something was on board that shorted Q7180 to ground pin nearby. REplaced Q7180 U7100 C7125 and DCIN Fuse. I've changed Q7130 4 times now after replacing it short will be gone on pin 1 but if I plug charger in long it will burn Q7130 fairly quickly. I've checked the traces from Q7130 and all has good traces. Tried replacing ISL at the same time as Q7130 but no luck. Any chance the coil L7130 could cause this? Seems like I've seen this before.
Diode at PPBUS_G3H is .138
ISL voltages and resistance look ok other than 18,17,27,28 of course are low.
