This indicates a failure in the power-on sequence. Check the secondary voltages, specifically the RAM power rail ( +1.2V_VDDQ ) and CPU VCore ( +VCC_CORE ). If these are present, use the schematic to locate the SPI BIOS chip pinouts to dump, clear the ME region, and re-flash the firmware.

Working on this board without a schematic is nearly impossible due to the high density of components and the presence of multi-layered PCBs. The schematic provides:

If you are tracking down a specific component location on this board, I can help you find where it sits in the circuit. Let me know:

(Invoke related search terms.)

A significant percentage of motherboard failures stem from a breakdown in the power rail initialization sequence. The LA-C921P layout follows a strict hierarchical power tree. Understanding this sequence allows you to use a multimeter to isolate where the voltage drop occurs. Phase 1: DC-In and Charging Circuit ( VIN )

If both +3VALW and +5VALW are missing, the issue is typically located near the input protection circuit.

Ensure your physical board matches "Rev 1.0". If your board says "Rev 2.0" or "Rev 1A", some component labels or resistor values may differ slightly from the documentation.
