For detailed troubleshooting, the following technical files are typically used by professionals:
Finding only ~2V on SRTC_RST# and ~0.1V on RTC_RST# instead of the required 3V.
Technicians often observe a "low load" state where the motherboard remains in a suspended mode (load approx. 0.042A) and fails to complete the power-on sequence.
