  1. VIN (19V): Should be present at the first MOSFET after the DC jack.
  2. 3V_ALW / 5V_ALW: Always-on voltage. If these are missing, the EC (Embedded Controller) won't work.
  3. EC_RST#: Reset signal for the Embedded Controller.
  4. NBSWON#: When you press the power button, this signal goes low.
  5. DNBSWON#: The EC acknowledges the button press.
  6. S5_ON: EC turns on the main power rails.
