Circuit diagram covering the Dell Latitude E7270 and E7470, both on the Compal LA-C451P board. The file is a standard PDF, so net names and part references can be searched in any reader. It is useful for tracing the power-on sequence, checking the charger and battery path, locating fuses, and following signals between the PCH and the connectors. Compal assigns LA-xxxxP numbers to its designs, and that code appears on the PCB. The name gives no revision, so check the revision on the board against the schematic title block.
