Embedded controller firmware for a Lenovo board coded NM-A362, named for the ACLU4 and ACLU3 platforms in the UMA version with integrated graphics only. The 38.7 KB RAR holds code for the ITE IT8586E keyboard and power controller, not the main BIOS. NM-prefixed numbers come from LCFC, Lenovo's own design arm. A damaged EC image often causes no power, no charging or a dead keyboard. Confirm the board and UMA layout match before programming the IT8586E or its external flash.
