The board has waterdamage in the battery connector area. It still boots to OS, but it's not detecting the battery. SMBUS_BATT_SCL measures 0.4 ohms to ground. R5381 measures 2000 Ohms from the PP3v42 side. I already replaced D7050, but the short is still there. the only other termination points i can find in the schematic are on U5000 and U7100. Is there a way to tell if its U7100 other than replacing it? or could the short be somewhere else still?
