BIOS together with EC firmware for the HP ENVY m7-n TouchSmart laptop, board LA-C752P, in a 19 MB RAR archive. LA-xxxxP numbers follow Compal naming, so Compal manufactured this motherboard. Having both the system BIOS and embedded controller firmware is useful when a machine shows no power, charging or keyboard faults, since the EC handles those functions. Flash with an SPI programmer after reading and saving the original contents, confirm the PCB board number, and ensure each image matches its chip size.
