Firmware package for the ASUS X409JA laptop, revision 2.0 board, containing both the BIOS and the EC firmware and described as fully working; the RAR archive is about 21 MB. The embedded controller handles power sequencing, keyboard, battery and fan, so a corrupted EC image can cause no-power or charging faults even when the BIOS is fine. Each image is written to its own chip or region with a programmer. Back up the original contents first and verify that each file size matches the target chip.
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.
