Once you press the power button (PWR_SW#), the EC activates the main VRMs:
For a "No Power" or "No POST" issue, this is the most important part. It outlines the "S-states" (S5, S3, S0). You can use your multimeter to check if the board is stuck in a specific state. For example, if you have +3VALW (Always-on voltage) but no +3VS (Switched voltage), the schematic will point you to the specific MOSFET responsible for that conversion. 3.

It helps you trace signals like PLT_RST# (Platform Reset) or PWR_SW# (Power Switch signal) to see where communication is breaking down. Critical Sections of the LA-G121P Schematic Once you press the power button (PWR_SW#), the
