BIOS .zip 31.7 KB Shared

Small ZIP with keyboard controller firmware for the ASUS K551 series on the S551LN motherboard, for the ITE IT8585 embedded controller named in the file. At 31.7 KB it holds EC code, not the main BIOS, and is used when the laptop shows no power, charging faults or keyboard problems linked to a corrupted EC. Writing an ITE controller usually needs a dedicated EC programmer or a flashing tool for that chip family. Confirm the controller marking on the board and keep a copy of the original contents before reprogramming.
