I got a t450 and my screen is damaged I bought a new one B140HAN01.3. The screen works great but there is no way to control the backlight.
I tried https://www.reddit.com/r/thinkpad/commen...whitelist/ but the laptop is beeping at the start and the backlight does not dim.
Factory screen was 1600x900
This is my factory BIOS: https://file.io/p8uBBtYjmwA8
BIOS version: JBET73WW (1.37) 2019-08-14
Embedded Controler version: JBHT17WW (1.04)
Model is: 20BV0001US (Lenovo T450)

Hi
How did you get this file?
Do you have a SPI-programmer?

hi, i wanted to try and use a spare thinkpad i had lying around as a file server, i don't need the wifi card so i figured pcie is basically all the same, bought a AEkey m.2 to Mkey m.2 to use a cheap m.2 to sata HBA.
but it doesn't appear to work.
i found out the wifi whitelisting thing and was wandering if that is maybe the cause of the problem.
