Based on hundreds of repair logs, here are the top 5 issues on this motherboard:
Vital for checking keyboard connectors, LVDS/eDP screen cables, and BIOS chips. Common Troubleshooting Scenarios 1. No Power (Dead Board)
Power enters through the DC jack. It passes through the protection reverse-polarity MOSFETs (typically controlled by the Charging IC, often an Intersil/Renesas ISL series or TI BQ series). If these MOSFETs are shorted or lack a gate voltage, the entire board remains completely dead.
