EC ROM for the HP ProBook 440 G8, the embedded controller firmware, packed in an 8.79 MB rar. The EC handles power sequencing, battery charging, keyboard and fan control, so a corrupt EC image can cause no-power, no-charge or dead keyboard symptoms even when the main BIOS is fine. On many HP boards this code shares the SPI chip with the BIOS, so confirm the layout before flashing. No board number is given; match the PCB code and back up the original chip first.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfilebins. Enginerys does not host this file.
