Description
LENOVO ThinkPad_T460S_NM_A421_REV_3_0_N1CET47W_ME_Cleared_16MB TESTED OK BIOS dump for the Lenovo ThinkPad T460S laptop, board number NM-A421, revision 3.0, made by Compal and supplied for a 16 MB flash chip with the Intel ME region cleared. The uploader marks it as tested, but that is their claim and has not been verified here. Technicians use a dump like this to reprogram the SPI chip with a programmer after a corrupted BIOS or a failed update. Before writing anything, confirm that the board number and revision match your machine and save a backup of the original chip contents.

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 T460S NM-A421. 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.
