Firmware set for the Lenovo G580, type 20150, on the Compal LA-7981P board, containing both the main BIOS and the EC image in a 2.95 MB ZIP. Having both files makes it easier to fix boards where the embedded controller or the system flash is corrupted, for example with no power-on, a dead keyboard or charging faults. Compal designs carry LA-xxxxP numbers on the PCB. Identify which chip each image belongs to, dump the originals with a programmer, and check the capacities before flashing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
