Firmware archive labelled Z580, which matches the Lenovo IdeaPad Z580 naming, compressed to about 2.77 MB; the name gives no version or board revision. Extract it with an archive tool to check whether it holds a full chip dump, EC firmware or an update package. Full images are written with an SPI programmer to restore boards with corrupted firmware. Confirm the chip capacity equals the extracted image size, compare the motherboard number printed on the PCB, and back up what is already on the chip before any write.
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.
