If the laptop exhibits zero signs of life, trace the DC-In jack pins on the schematic. Locate the first two isolation MOSFETs (protection switches). Measure the voltage at the drain and source. If 19V enters the first MOSFET but does not exit the second, check the gate voltage driven by the Charger IC.
