Ideapad 520S - Brightness changes on its own

Hello,

 

Sometimes when I use my Ideapad 520S, its screen brightness changes on its own. It dims for a while, and then turns back to regular screen brightness. Why is this, and how do I change it?

 

I have "Enable adaptive brightness" turned off.

 

Cheers,

Herman

Hi HermanSandblom! thanks for posting in our community. 

 

Have you already checked the Intel Driver control panel? Just uncheck the power saving technology then check if you have the same issue after. Thanks.

Re: Ideapad 520S - Brightness changes on its own

Hello again. It seems I was wrong; my screen is still changing its brightness on its own. Any other ideas on what the cause may be?

 

PS. These are my Intel power settings:

Hey there, HermanSandblom!

 

Please run the Lenovo Vantage app https://pcsupport.lenovo.com/us/en/solutions/ht505081?CID=ww:lenovosocial:20x9m6 and check for a system update, then install them all. After that, test the laptop again.

 

Regards!
