Schematic for Compal motherboard LA-3581P, project ICW50, built around the Nvidia MCP67-MV chipset, supplied as a PDF in a 1.13 MB RAR. Compal uses the LA-xxxxP pattern for its notebook boards, and the brand of the finished laptop is not given in the name. The diagram helps trace the power-on sequence, chipset rails and clock signals, and is useful when diagnosing no-power or no-display faults on MCP67-based systems. Check the board number and revision on the PCB before relying on part values.
