Schematic PDF for the Compal LA-H492P motherboard, revision R01, compressed in a 7.04 MB RAR. Compal is a major notebook ODM and its LA- numbers identify boards shipped in laptops from several brands, but the name does not say which model this one serves. The diagram is used to follow power rails, the charger and PWM circuits, the power-on sequence and signal paths during component-level repair. Confirm the LA number and revision silkscreened on the PCB match before trusting values or part references.
