The PMIC is responsible for generating and regulating all power rails on the motherboard. When troubleshooting a dead device, the PMIC is one of the first components to check. Using a multimeter in diode mode, technicians should inspect the large input capacitors surrounding the PMIC for shorts. With a known-good battery connected, the battery connector should show a steady voltage between 3.7V and 4.2V.

Turn off power, switch the multimeter to diode mode, and check major buck coils for shorts to ground. A low reading (near 0.000V) indicates a shorted capacitor or a dead IC on that specific rail. Problem B: No Display / Fake Charging
