Embedded controller firmware image for the Compal board LA-H031P, delivered as a raw 128 KB ROM file. The EC manages power-on, battery charging, keyboard and fan control, so a corrupted EC can leave a board completely dead or unable to charge. This file is written to the EC chip or its dedicated flash using a suitable programmer. Compal LA-xxxxP boards are built for several laptop brands; confirm the board number on the PCB, back up the original EC contents, and make sure the target chip capacity matches 128 KB.
