BIOS firmware archive for the ASUS X550CL laptop, with the name also listing the F552CL, a related regional variant of the same platform. The RAR archive is 3.67 MB and should hold the SPI flash image for the mainboard. Use it to restore a board that powers on without display or is stuck after a failed BIOS update, writing the image with an external programmer such as a CH341A. Before use, check the board model printed on the PCB, confirm the file size matches the chip capacity, and keep a backup of the original dump.
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.
