4887 When troubleshooting a device that will not power on, follow the standard bench sequence:
4888
4889 1. **DC-In & Input Stage Isolation**:
4890 - Check **+19V_DCIN** or **+20V_USB_PD** after the input MOSFETs. If voltage drops below 19V under load, check for a shorted DC jack or cracked ceramic filter capacitor.
4891 2. **Always-On Standby Rails**:
4892 - Verify **+3.3V_ALW** (Coil PL301) and **+5.0V_ALW** (Coil PL302). The Super I/O Embedded Controller (EC) cannot register the power button if +3.3V_ALW is missing.
4893 3. **Power Button Trigger & RTC Reset**:
4894 - Check that the power button signal (\`NBSWON#\`) pulls down from 3.3V to 0V when pressed.
4895 - Perform a 30-second CMOS/RTC hard drain to reset stuck power state machine registers.
