Compal schematic for board LA-E131P, project CAZ20, revision 1.0 A00, compressed into a 1.72 MB RAR archive. The LA- number follows Compal's pattern, and this design is the Dell Latitude 7480 motherboard. The circuit diagram shows power sequencing, the charger, the EC, voltage regulators and their enable signals, so it guides measurements during no-power, no-charge or no-display faults. Make sure the board revision printed on the PCB matches before trusting part values and references.
