Asus=128=X555LD Rev 3.3 IT8585 (EC)

BIOS .zip 445 KB Shared

Embedded controller firmware for an ASUS X555LD motherboard, revision 3.3, intended for the ITE IT8585 EC chip, packed in a 445 KB ZIP. The EC handles power sequencing, the keyboard, battery charging and fan control, so a corrupted EC image can leave a board that will not turn on or charge. Confirm the IT8585 and board revision on your unit, back up the existing EC contents, and use a programmer or method that supports this controller before writing anything.
