HP EliteBook firmware package for the Wistron board 13324-1, containing both the BIOS and the EC (embedded controller) firmware, and marked as working. The EC handles power-on, charging, keyboard and fan control, so a corrupt EC image can cause a dead board even when the BIOS is good. Numbers in the five-digit-dash-digit format follow Wistron's scheme. Identify which chip holds each image, back them up with a programmer, and confirm the board number before writing.
