Greetings, Anon!

 

I had the same problem and fixed it by taking these steps (note, however, that my computer is not in english, so the bold names are translated and may differ from the names you'll see. Feel free to correct any inaccuracy) :

 

• Right-click on the desktop and select "Intel graphics settings".
• On the newly openned window, click on "Power".
• Then, select "Battery powered" on the menu to the left, and set "Technology of reduction of current consumed by the screens" to "Off".

I hope it will serve you well.

P.S. : My PC is a T470 running Windows 10.

Solved my problem, thanks

None of these solutions has helped me. My brightness continues to incrementally decrease (when the subject on my screen is more dark than bright) or increase (when the subject is brighter than dark). In other words when I go from a white screen to a black screen my brightness levels with start to decrease and get darker. And vice-versa. I have a Lenovo ideapad 330-15 with a gtx 1050 if that helps. 

Having the same problem on my new Legion Y530. Have done everything I've found, including all that has been mentioned in this thread (except for that Intel stuff I don't have) and browsed through a ton of web pages and windows settings. I kind of know my way around computers so it seems that there just isn't a solution meant for the end user to find and use.

Seeing that I'm not alone with this problem, I think Lenovo really should give a solution for us and not just offer some 'please check the sun is shining' -kind of answers or basic RTFM stuff. Other than that, I like this laptop very much but this problem makes me want to toss it out of the window. Makes me really p****d.

I had similar problems where the brightness and even the color tone of the screen would change on their own.

I followed these steps, which seem to have fixed my display problems completely so far:

I hope this helps.

For the people who don't have an Intel control panel, I was able to install it via the Microsoft Store.

Here a link to the app: https://www.microsoft.com/store/productId/9NDLCLMMTMRC

Great, thanks! This also solved the dimming issue for my T580. Can't believe I missed the entire Power section of the Intel settings. I just looked at everything in the Display section, which I thought was logical... :)

Glad it helped!

And you are, going to the usual Display Settings is the logical thing to do. That's why this topic has become an issue for many people. In my opinion, all these power saving sattings that interfere with the performance of the screen should be turned off by default to avoid frustration of us users.

Most of us buy a laptop with these specs need it for heavy / professional use and it doesn't make sense that they bury the options to make it work properly so deep in the settings.

Thanks @mariomartin! Number 3 solved my issue.

Happy to help!
