Embedded controller firmware for the ASUS FX505DY laptop, a raw .bin packed in a small ZIP of 44 KB. The EC handles power-on, charging, keyboard and fan control, so a corrupt EC image can cause no-power or no-charge faults. The binary is written to the EC or its flash with a suitable programmer. Read and save the original contents first, check that the chip size matches the image, and confirm the board model before flashing.
