Adaptive Brightness wont turn off

2017-09-02, 9:57 AM

Hi i have a problem with my girlfriend laptop Flex 14 laptop Ideapad (S/N QB********) with sys W10. There is Adaptive brightness function and it cant be turn off. I tried every step on this site    https://www.eightforums.com/tutorials/6042-adaptive-brightness-turn-off-windows-8-a.html and it still turning on. Interesting is the option 1 (controll panel) and 2 (settings) if i turn off  Adaptive Brightness or uncheck box (settings) and i restart system it again turn on in control panel and check the box in settings. I have no install Lenovo power managment utility does it have any influence? Do u have some solutions for this problem. Thank you for answer :) i have no idea what should i do.

Hello Vejce

Thanks for using the Lenovo forums.

Try to download the Video and Chipset drivers for the unit from the support page.


Make sure to reboot after an update on the unit.
See if this can make a difference.


Hope this helps, let us know how you get on.

Did someone help you today? Thank them with a Kudo!
