EC firmware archive for the Lenovo B50-70 on Compal board LA-B092P, with 128 and ZIWB2302 in the name. ZIWB2 is the board's platform code, and 128 likely marks the 128 KB EC image size, though that is not stated outright. The small 61.0 KB zip holds the embedded controller firmware, which governs power-on, charging, keyboard and fan. LA-prefixed numbers are Compal designs. Match the board, back up the existing EC contents, and program the correct chip with a suitable tool.
