Embedded controller firmware for the Lenovo G510, 2 MB, marked EC in the name and evidently intended to be used together with a separate BIOS image. The EC handles power sequencing, battery charging, keyboard and fan control, so a corrupted EC can leave a board that will not power on. This image is written to its own SPI chip with a programmer. Confirm the board code on the PCB and the chip capacity, back up the original contents, and pair it with the matching BIOS file for the same board.
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 @biosarchive. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
