Once you open the schematic (PDF), focus on these pages:
Page 1–3: Block diagram & power sequence
Page 10–15: Power rails
Page 25–30: Embedded Controller (EC) – ITE8578 or similar
Page 40–45: CPU & PCH (Integrated in AMD SoC)
Page 50+: Connectors
Since the LA-D402P schematic is proprietary, the following diagnostic workflow is recommended:
