: The chip responsible for fan control, keyboard matrix mapping, thermal monitoring, and initial boot-up sequencing.

If the gate voltage is missing, trace back to the charging IC (e.g., ISL, BQ series) to verify its VCC and ACDET (AC Detect) pins. Step 2: Test for Shorts to Ground Switch your multimeter to resistance mode (or diode mode). Place the black probe on a known chassis ground. Probe the large inductors (coils) across the board.

Protects the circuit from high-voltage spikes.
