Lenovo embedded controller firmware for the NM-A361 motherboard, referencing the ITE IT8586E keyboard and power-management controller. NM-prefixed numbers belong to LCFC, the Lenovo-owned ODM, and the small 40.9 KB zip size fits an EC image rather than a full system BIOS. EC code governs power sequencing, charging, fan and keyboard behaviour, so a corrupted EC can leave a board dead or unable to charge. Check that the PCB carries NM-A361 and the same IT8586E chip, back up the existing contents, and use a programmer or tool that supports this ITE controller.
