Lenovo G505-20240

BIOS .rar 1.80 MB Shared

Firmware archive for the Lenovo G505, machine type 20240, delivered as a 1.80 MB RAR. The name gives no board number, revision or BIOS version, so check the motherboard label before using the content. Such images are written to the SPI flash chip with an external programmer to fix a board stuck without display or in a boot loop. Back up the original dump first to keep serial and Windows license data, and verify the extracted file size matches the flash chip installed on the board.

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.
