Keyboard controller firmware for the Lenovo G505S on a Compal LA-A091P board, marked for the ENE KB9012 (P suffix variant) chip. The 128 KB binary corresponds to the full on-chip flash of that embedded controller. A clean EC image is the usual cure when the machine refuses to power on, the battery will not charge or keys stop responding. Write it with a dedicated KB9012 programmer via the keyboard FPC pins, after dumping the existing code as a backup, and verify the board number silkscreened on the PCB before flashing.
