EC firmware for the Lenovo G480 on Compal board LA-7981P, written for the ENE KB9012 keyboard controller, with A3 likely marking a version or board revision. The ZIP is only 58.4 KB, consistent with an embedded controller image. A faulty EC can cause no power, charging faults or dead keyboards, and the KB9012 is usually reprogrammed through its keyboard connector pins with a dedicated EC programmer. Compal uses the LA-xxxxP pattern, so confirm the board number and save the existing EC contents before writing.
