Firmware package labelled 640 G1, matching the HP ProBook 640 G1 business notebook, though the name gives no board number, revision or CPU details. At 27.1 MB the ZIP is large, suggesting several images, a full update package or extra tools rather than a single SPI dump. Open it and identify which file suits the chip on your board. Before writing anything with a programmer, save the original flash contents, confirm the board number on the PCB, and verify that the image size equals the 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 @Laptopdesktopbios. Enginerys does not host this file.
