Small ZIP archive of about 58 KB holding what the name calls an EC binary, an embedded controller firmware image, with no model, board number or version stated. The embedded controller handles power sequencing, the keyboard, battery charging and fan control, so a corrupted EC image can cause no-power or charging faults. Because the target device is unknown, verify the source and compare the image size with the EC chip or its flash before writing. Always read and save the original contents with a programmer before flashing anything.
