Firmware set for the Dell Latitude E6520 on board LA-6562P, containing both the main BIOS binary and the EC firmware according to the name, in a 5.02 MB RAR. LA-xxxxP numbers follow the Compal pattern, so the board was made by Compal for Dell. Having the separate EC file helps when the keyboard controller chip is corrupted and the laptop shows no power or charging faults. Confirm the PCB marking matches LA-6562P, dump both original chips with a programmer before writing, and make sure each image size suits its flash chip.
