Embedded controller firmware for the Samsung NP550P5C, written for an ENE KB9012 keyboard controller, with the version or tag AAA in the name. The small 33.9 KB archive fits the size of a KB9012 EC image. A corrupt EC can cause no power, no charging or a dead keyboard, and reflashing usually requires a KB9012-capable programmer connected through the keyboard connector or the chip pins. Read and save the existing EC contents first, since some images contain board-specific data.
