When the laptop shows no signs of life, the primary power rail (often labeled as VIN or +19V ) must be traced. The schematic helps locate the initial DC-in MOSFETs and the charging IC. Technicians check if the 19V rail is shorted to ground or if it fails to pass through the secondary isolation MOSFET due to a faulty gate signal. 2. Missing Always-On Power Rails (+3.3V and +5V)
