EC firmware for the ASUS X550LC motherboard revision 2.0, a 128 KB binary marked as working. The embedded controller manages power-on, battery charging, fans and the keyboard matrix, so reflashing it can fix a board with no power response or charging faults when hardware checks pass. Write it to the small EC chip with a programmer. Check that the board is an X550LC with the revision 2.0 marking, and back up the existing EC contents before writing in case the image needs to be reverted.
