Compressed archive labelled for the Lenovo V310 laptop, filed as BIOS or firmware material and about 4.37 MB in size. The name gives no board number, revision, chip size or content list, so extract it and inspect what is inside before use. Archives of this kind usually hold a raw SPI dump or a vendor update package. Check the motherboard number printed on the PCB against any notes in the archive, back up the current flash chip with a programmer, and verify the image size equals the chip capacity before writing.
