Small ZIP archive with an EC firmware image, judging by the name, but no model, brand or board number is given, so its target device is unknown. Embedded controller firmware handles power-on, battery charging, keyboard and fan control, and a corrupt copy often leaves a laptop dead. At 58.3 KB it suits a small EC flash or internal EC memory. Only flash it once you have confirmed which board it came from, and save the existing EC contents first with a suitable programmer.
