PDF schematic for the Dell Latitude 5400, project EDC41, Compal board LA-G891P, compressed in a RAR archive of about 3.18 MB. Compal designs many Dell boards and labels them with the LA-xxxxP pattern. The document allows tracing power rails from the USB-C or barrel input through the charger and regulators, checking power sequencing, reading signal names and finding component values when diagnosing no-power or no-display faults. Check the board revision on the PCB before trusting specific details.
