BIOS dump archive for the Lenovo Flex 2-15, board LF15M with number 13308-1, following the Wistron numbering scheme. Wistron designs many Lenovo consumer laptops and marks boards with a five-digit code and a revision suffix, so the -1 should match the PCB. Unpack the RAR and write the image to the SPI flash with a programmer to recover a unit with corrupted firmware. Always read and keep the original chip first, since it holds serial and licence data, and confirm the size fits.
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.
