Compal LA-2421 motherboard schematic at revision 0.6, a 1.09 MB PDF. This older Compal board code appears without the P suffix seen on later designs, and the name gives no brand, chipset or model. The circuit diagram lets a technician follow voltage rails, look up resistor and capacitor values, locate test points and trace the power-good chain when a board fails to start. Make sure the code and revision on the PCB match, since a 0.6 drawing may differ from production hardware.
