Embedded controller firmware for the Acer Aspire 5750G, motherboard LA-6901P revision 2.0, as a 128 KB binary. The LA- prefix marks Compal as the board maker. EC firmware controls power-on sequencing, charging, keyboard and fans, so a corrupted EC can leave a board dead or unable to charge. Program it to the EC chip or its separate flash with a suitable programmer, saving the original contents first, and confirm the LA-6901P revision printed on the PCB matches before writing.
