Embedded controller firmware for the Compal LA-9104P board, prepared for the ENE KB9012 keyboard controller named in the file. The 128 KB binary matches the internal flash size of that controller, which is usually programmed through its test pads or a dedicated KB9012 adapter. A damaged EC image typically causes no power, no charging or keyboard faults. Before flashing, confirm that the board is LA-9104P with a KB9012 fitted and dump the existing code, because EC firmware is tuned to each board design.
