Firmware archive for the Q502LA laptop, with 1.1 in the name likely marking the board revision. At only 122 KB the RAR is small, so it may hold a compressed BIOS, an EC image or a partial file rather than a full SPI dump; inspect the contents first. Such files help recover a unit that fails to boot after a corrupted update when programmed into the right chip. Compare the revision with the PCB marking, back up the existing chip, and verify the extracted image size equals the target chip capacity.
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 @afsbiosfree. Enginerys does not host this file.
