Lenovo G50-45 firmware archive for LCFC board NM-A281, sized 2.31 MB in RAR format. LCFC, Lenovo's own design arm, numbers its boards with an NM-xxxx code on the PCB. The name lists no revision, EC details or ME status, so check the extracted files. Technicians write such images to the SPI chip with a programmer to fix a board that will not post after corruption. Back up the original first, match the NM-A281 marking, and verify that the image size suits the installed flash chip.
