Schematic for the Dell Latitude E6420, designed by Compal as board LA-6592P, supplied as a PDF in a 1.42 MB RAR archive. Compal marks its mainboards with LA-xxxxP codes on the PCB, so confirm the number and revision there before relying on part values. The drawings support tracing the power-up sequence, checking charger and DC-DC regulator stages, finding shorts on rails and following signals from docking, USB and display connectors back to the chipset and embedded controller.
