Firmware set for the Dell Inspiron 15 3531 on Compal board LA-B461P, mentioning the KB9012 embedded controller, in a 2.75 MB RAR. The ENE KB9012 holds the keyboard and power management code, so a corrupted EC can cause no power, no charge or dead keyboard faults. It is commonly reflashed with a dedicated EC programmer or adapter.
