Circuit diagram in PDF format for the Compal LA-B843P motherboard, around 4.09 MB. The name carries only the board number, with no brand, model or revision given. Compal uses the LA-xxxxP scheme for laptop boards it produces for various brands, so the code silkscreened near the board edge is what you match against. Open it in any PDF reader and use the pages to follow the charger, system and CPU rails, check enable and power-good signals, and locate part references. Verify the revision before relying on values.
