Schematic diagram in PDF for Compal board LA-C551P revision 1.0, the same number used on the Dell Precision 7710. The name gives only the board number and revision, not the laptop model. Compal schematics document the power sequence, voltage regulators, EC connections and component values page by page. Technicians use them to follow rails, identify the parts involved in a no-power fault and check expected voltages. Use it alongside the boardview, and confirm the PCB revision matches.
