BIOS dump for the Lenovo G50-45, machine type 80E3, with ACLU5 in the name, which is the board designation often seen on this model. The file is 8.00 MB, matching a 64 Mbit SPI flash chip. It can be written with a programmer such as a CH341A to restore a board with corrupted firmware or no display. Confirm the chip capacity and board marking match, save the original contents before erasing, and expect serial number or system data to need re-entering if they differ from the donor dump.
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 @biosarchive. Enginerys does not host this file.
