Firmware dump in a ZIP archive labelled only with the board reference U16 and the chip marking W25Q16FVSIG, a Winbond 16 Mbit (2 MB) SPI flash in SOIC-8. No laptop model, brand or board number appears in the name, so the source device must be confirmed by other means. A clean image for this chip should be 2 MB, and a larger file will not fit. Read and keep a backup of the existing chip before programming, and verify the U16 location and part marking on the actual 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 @SCHEMATICWORLD. Enginerys does not host this file.
