Embedded controller firmware for the ASUS FX505DU, supplied as a small zip archive of about 36.5 KB containing a binary image. The name identifies only the model and the EC role, with no board revision or version number given. The EC handles power sequencing, battery charging, keyboard and fan control, so a corrupted EC image can cause no-power or no-charge faults. Reflash it with a suitable programmer or tool, confirm the EC chip and board match your unit, and keep a backup of the original contents before writing anything.
