HP embedded controller firmware, 128 KB, with a generic name that states no model, board number or version. The EC runs power on sequencing, battery charging, keyboard and thermal control, so a damaged EC image can leave a laptop dead or without charging. A 128 KB file fits a 1 Mbit flash or an EC region size. Identify the matching machine before use, perhaps from strings inside, and back up the original EC chip before programming with an external programmer.
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.
