A 128 KB embedded controller firmware file for the HP 15-ay004ne notebook on Compal board LA-D703P. The EC handles power sequencing, charging, keyboard and fan control, so a corrupted EC image can leave a laptop dead or unable to charge. Compal uses the LA-xxxxP pattern for its notebook mainboards. Depending on the design, the EC code sits in its own small chip or in the main BIOS flash. Confirm the board code, check where the EC firmware is stored, and back up the original first.
