BIOS and EC firmware for the ASUS FX505DU gaming laptop mainboard, revision 2.0, bundled in a 4.53 MB RAR archive. Both the system BIOS image and the embedded controller firmware are included, which covers typical no-power, no-boot or keyboard and charging faults caused by corrupted code. Flash them with an SPI programmer to the corresponding chips. Read the existing chips first to keep a backup, and make sure the board revision printed on the PCB matches 2.0 and that chip capacities fit the images.
