There is a short to ground on PPBUS_G3H, feel U7100 to see if it is getting hot. If it is not, remove F7140 and see which side the short to ground is located, where PPBUS is created (charging chip side) or system side (anything powered off of this line). Keep in mind this voltage goes to at least one 4 way low ohm resistor, so something from this could be shorting PPBUS_G3H to ground. If you don't notice any visible damage, try injecting a small amount of voltage on this line and see what gets hot.
