Hi!

In Lenovo ThinkPad T450, any modified bios can be flash using hardware SPI programmer only, exactly the same as described in the first post of this thread.

So, for creating backup (dump) of bios you need to use hardware SPI programmer only.

I used a CH431 to do the dump the file

Can you mod my T450 bios for display brightness support?
