Bios Mods -The Best BIOS Update and Modification Source

T450s want to add LCD panel so brightness controls work:

LP140WF3(SP)(D1)

Thank you!

Hello,  I have a T450s and just upgraded the screen. Now brigthness control is not working on Windows, it works fine on Linux. I'm new to this bios modding stuff and I already ordered CH341A

My new screen AUO B140HAN02.4

Thank you!

a friend of mine owns a T450 with a JBET73WW UEFI/BIOS. he would like to install a linux on it and somehow the installation stuck at the beginning. he would like to use UEFI only but the installation stops with a blank screen. as far as i understand it's a UEFI issue with a few Lenovo models and several owners facing with this (https://github.com/ventoy/Ventoy/issues/214). is it possible to fix it with modding?

Good day! Please help me remove the whitelist of network cards from the BIOS of my T450. How do I get a BIOS dump? A CH341? Links from the first messages do not open.

Hi
"LCD whitelist" does not exist, need to edit the screen driver
have you installed the new screen yet?

Yes, I installed a new screen and as a result the brightness adjustment in Windows does not work, there are no problems with Linux

writing to the chip EDID is blocked and I can’t correct the ID MFG in the panel .....
