Embedded controller firmware matching the VAWGA204 main BIOS, 128 KB in size; no laptop model or board number appears in the name. The EC handles power sequencing, battery charging, fan control and the keyboard, so a corrupted EC image often causes no power or charging faults. Flash it to the EC chip or its dedicated flash with a suitable programmer, ideally together with the matching main BIOS. Read and save the existing EC contents first, confirm the target memory is 128 KB, and check the board number before relying on it.
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 @bios_laptop. Enginerys does not host this file.
