BIOS for the Lenovo G50-80, model type 80E5, for board NM-A361. The NM-xxxx numbering follows LCFC, Lenovo's own design arm. The 3.62 MB RAR should hold a raw SPI image that is written with an external programmer to recover a laptop that will not start or shows a black screen. Verify the board number printed on the PCB, back up the existing chip contents, and check the extracted file size matches the capacity of the flash chip before writing.
