EC firmware binary for an HCL H54Y laptop, UMA version with integrated graphics, HM55 chipset, 64 KB in size. Embedded controller firmware handles power-on, the battery and charging, the keyboard and fans, so a corrupted EC often leaves a board dead or unable to charge. The file is written to the EC or its separate flash with a suitable programmer. Identify the EC chip on the board first, back up its contents, and confirm that the 64 KB image matches the chip capacity.
