La-j641p Schematic [patched] -
The most critical section for repair. It lists the precise order signals must turn on (e.g., +VIN -> +3.3V_ALW -> +5V_ALW -> RSMRST# -> PWRBTN# -> SLP_S3# -> SLP_S4# -> VR_ON). The LA-J641P uses a modern Intel S0ix power state.
Using a schematic for a similar board (e.g., LA-J651P) will lead to misdiagnosis. The power sequence, resistor values, and BIOS pinouts differ significantly. la-j641p schematic
