BIOS image for the ASUS X540LJ laptop, version 301, supplied as a BIN file in a 3.48 MB ZIP. Technicians write such dumps with an SPI programmer such as a CH341A when the original firmware is corrupted and the machine fails to start or shows no display. Before flashing, read and save the existing chip contents and confirm the extracted image size matches the flash chip capacity, because a mismatched image will not fit. Make sure the board really is an X540LJ variant, since ASUS boards with similar names can need different firmware.
