Schematic for the EPW50 project, Compal board LA-H323P revision 1.0, provided as a PDF inside a 3.24 MB RAR. LA-prefixed numbers follow Compal numbering, so the board was built by Compal regardless of the laptop brand. The diagram lets a technician follow power sequencing, charger and CPU rails, and signal paths when hunting a short or a no-boot fault. Make sure the PCB silkscreen reads LA-H323P rev 1.0 before relying on values, since later revisions may change components.
