BIOS dump for the ASUS X421JA laptop mainboard, revision 2.0, packed in a 5.60 MB RAR archive. According to the name the Intel Management Engine region has been cleaned, and the triple OK tag suggests the uploader marked it as tested and working. A cleaned ME image is normally written to the SPI flash chip with a hardware programmer such as a CH341A when a board will not boot or power on. Confirm the revision printed on the PCB matches 2.0, and save a backup of the original chip contents before writing.
