EC firmware for the ENE KB9012 embedded controller on the Compal LA-9911P motherboard used in the Lenovo G505, marked OK in the name as reported working. The small 52.6 KB RAR fits a KB9012 image, which is reflashed in circuit or via the keyboard connector with a suitable programmer. A corrupt EC causes no power-on, dead keyboard or charging faults. LA-xxxxP is Compal numbering, so check the code and revision on the PCB, and read the current EC contents before writing this file.
