BIOS image for a Lenovo ThinkPad L440 board numbered 12289-2, 8.00 MB, labelled as a new bin. The five-digit dash-revision number follows Wistron's board scheme, the ODM behind this design. The 8 MB size fits a 64 Mbit SPI flash chip; check the chip on your board before programming, since some boards split firmware across chips. Read and save the original contents first so serial and system data can be restored, and confirm the PCB board number matches 12289-2.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
