Embedded controller firmware for the ASUS X540LJ, board revision 2.0, intended for an ITE IT8585E keyboard controller according to the name. The raw binary is 128 KB. The EC handles power-button logic, battery charging, fan control and keyboard scanning, so a corrupt EC image often shows up as a dead board, no charging or a power-on that never completes. Flash it with a suitable programmer or EC tool only after dumping the current contents, and make sure the board revision on the PCB is really 2.0 before writing.
