Description
BIOS dump for the Lenovo ThinkPad L440 laptop, supplied for an 8 MB flash chip with the Intel ME region cleaned. The original file name points to a W25Q64 chip and the LOS-1 RJ45 board, so you can compare those against the chip and board you are working on. Technicians use a dump like this to reprogram the SPI flash with a programmer after a corrupted BIOS or a failed update. Confirm the board number and revision match yours, and back up the original chip contents before writing anything.
For the Lenovo ThinkPad L440 the catalog also has 2 schematics and 3 BIOS dumps.

Questions about this file
How do I flash this BIOS dump?
Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.
Will this BIOS work on my board?
Only if the board number and revision match: Lenovo ThinkPad L440. Dumps from a different board or revision can leave the board dead.
What does “clean ME” mean?
The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
