EC ROM image for the A715-71 built on Compal motherboard LA-E911P, code C5MMH, provided as a 128 KB binary. It holds the embedded controller firmware, separate from the 8 MB system BIOS, and is used when the laptop does not respond to the power button, fails to charge or the keyboard is dead. LA- prefixes identify boards designed by Compal. Read the existing chip or controller contents first, and check the PCB revision matches before flashing with a suitable programmer.
