Embedded controller firmware for the Compal LA-E891P board, about 60 KB, packed in a ZIP archive. The EC manages power buttons, charging, battery communication, fans and the keyboard. A damaged EC image often shows up as no power, no charging, or a fan running without the board booting. Find out whether your board keeps the EC code in a separate SPI chip or inside the controller itself before you program it. Save the original data first, and confirm the board number LA-E891P printed on the PCB.
