When the AC adapter is connected, 19V enters through the DC jack. This voltage must pass through two protective input MOSFETs (often controlled by the charging IC). If these MOSFETs are shorted or lack a gate voltage, the 19V rail will stop at the entrance, leaving the motherboard completely unpowered. Phase 2: Standby Voltages ( +3VALW and +5VALW )
