Schematic for Compal board LA-C551P, revision 1.0, provided as PDF in a RAR archive. Compal uses the LA- prefix for its laptop mainboards, and this board is used in the Dell Precision 7710 according to other files with the same number. The diagrams let a technician trace power sequencing, charger, CPU and GPU rails and locate parts on a shorted net. Open with any PDF reader and match the revision printed on the PCB.
