Dell Latitude E6520 schematic for Compal board LA-6563P, revision 1.0, Dell stage A00, provided as a 4.96 MB PDF. Compal uses LA-xxxxP codes on the boards it builds, and that code appears on the PCB rather than the Latitude name. Technicians use these pages to follow power rails, check the power sequence and charger, and locate parts responsible for a short. Any PDF reader will open it. Compare the revision printed on the PCB before relying on part values.
