Firmware archive for the Lenovo ThinkPad X280, machine type 20KE, packed as a 7.90 MB RAR. The name gives no board number or BIOS version, so check the files inside to see which image and chip they cover. Typical use is reprogramming the SPI BIOS with an external programmer when an X280 board is dead, cycles power or shows a black screen. Back up your existing chip before erasing it, and make sure the dump size matches the flash device.
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 @biosfilebins. Enginerys does not host this file.
