KBC firmware, meaning the keyboard controller or embedded controller code, for the Compal LA-9912P board, supplied as a 128 KB binary. The EC handles power sequencing, battery charging, fan control and the keyboard, so a corrupted image often leaves a laptop dead or unable to charge. The file is normally written with an EC programmer or an SPI programmer, depending on where the code lives on the board. Check that the PCB is really LA-9912P and save the existing contents first, since EC firmware differs between board revisions.
