I've got a brand new X1 Carbon (5th gen) that came in yesterday (14 Aug 2017). I can't find a way to disable the auto screen brightness feature. I've dug through the forum and it appears to be a common problem. I've tried:
1. there is no auto brightness option in the windows display settings
2. advanced power plan settings > display > enaable adaptive brightness > disabled
3. lenovo settings > display > dynamic brightness control > disabled
4. I don't see an ambient light sensor in the device manager (I could be missing it, as there is no sensors option. This helped some people with the 2014 model).
The screen changes brighness when I shift in my chair or when I switch from dark to light (or vice versa) background apps (like Chrome vs terminal).
Also disheartened that Lenovo "support" seems to be unavailable (after entering my serial number the webisite indicated that chat, email, and phone were not availble for my product in my country). Seriously guys?
Any help would be much appreciated. Happy to supply addtional details.
Solved! Go to Solution.

I don't have a carbon gen 5, but I have an x1 yoga gen 2, which I think will be similar. Run Lenovo Settings. Scroll down to where it says Control Panels and select Display. At the top is an option to do what you want.

I don't have a carbon Gen5. I am talking about the application "Lenovo Settings", not windows settings. Is it installed on your machine? If not, get that application.

Hi again rickh,
That is the Lenovo Settings application. Windows settings looks like this:

From the Windows start button, search for "Lenovo Settings". It is a Windows app.
Lenovo Settings / Display / Dynamic Brightness Control.
Hope that helps.

Mine has an extra line to shut off adaptive brightness. I also show sensors under device manager

I got ahold of Lenovo tech support and they thought it was a hardware issue (a bad panel) and were prepared to warranty the unit. I was pretty sure that wasn't it and a new one probably wouldn't help (based on the volume of people posting and reading about about this issue).
After a crazy amount of digging, my girlfriend found the answer:
right click on the desktop > Intel Graphics Settings > Power > Display Power Saving Technology > DISABLE for all power plans
Hey Lenovo and Intel, nobody wants this "feature"!
