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, I got a T450s and i would like to install a new IPS screen.
I was wondering if someone would be able to remove whitelist for wifi & LCD. And unlock advanced menu.
I tried to update the modules myself and got 5 beeps 2 times.....

"LCD whitelist" does not exist, need to edit the screen driver

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 .....
