Keyboard or embedded controller firmware stored as a 1 MB binary, with no model or board reference in its plain name. The size fits an 8-megabit SPI flash chip. A technician would program it with a hardware programmer to recover a laptop whose EC code is corrupted. Symptoms of corrupted EC code include no power-on, dead keyboard or failed charging. Because the origin is unstated, dump the original chip first, match the chip capacity, and confirm the image came from an identical board revision before writing it.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
