ZIP archive of 8.92 MB described as an EC ROM for the HP ProBook 440 G8. The embedded controller handles power sequencing, battery charging, keyboard and fan control, so a corrupt EC image can cause no power, no charge or dead keyboard symptoms. On many HP boards EC code shares the SPI flash with the BIOS, so inspect the archive to see what is included. No board number appears in the name; match your motherboard first, back up the chip and verify the image size before programming.
