Lenovo ThinkPad X1 Yoga 3rd Gen - auto brightness behaves erratically under Win10 Pro

2018-10-23, 12:54 PM

In some situations, the auto brightness behaves erratically under Win10 Pro on my Lenovo ThinkPad X1 Yoga 3.Gen. 2018 14". The brightness repeatedly increases and decreases by about 10-20% which is so annoying that in the meantime, I had to disable the automatic brightness function in Windows. 

 

I guess this is due to the ambient light sensor location but I have not been able to figure out a solution. 

 

Any tips?

do you have a suggestion that you forgot to attach or are you just quoting?

Hello, just to to report I have the same behavior on my X1Y3 (20LF). Auto brightness makes the screen lighting increasing and decreasing (sort of slow flickering), whereas the ambiant light did not change. 

Just enoying, but almost disappointing for a so hightech and expensive laptop....

Thinkpad X1Y3 20LF Windows 10 pro update 1803 version 17134.523

What you're descibing sounds like Intel Adaptive Contrast,

 

To turn it off, right-click on the desktop, select Intel Graphics Settings, click on the battery icon, and disable 'Display Power Saving Technology'. This setting has a tendency to reenable intself after updates.

 

Hope that helps.

 

Save it as a power profile so that every time there's an update you can go back to it.
