Yoga 2 13 Windows 10 Can't adjust brightness (Missing all brightness controls)

Hello there, 

I need help please! I can't fix the screen brightness. It appears to be stuck on full brightness which draws my battery life quickly and hurts my eyes during nights. The brightness button in the action center is missing, there is no brightness slide bar in the display setting nor in control panel, and brightness fn buttons in the keyboard are not working as well. When I click on the battery icon, there is a brightness button next to the battery saver button but also not working (not even clickable).

I searched online and I tried:

- updating/reinstalling/rolling back display drivers

- resetting pc (reinstalling windows)

- many other little repairs

 

College is starting soon and I really need my battery life and I will be studying on my laptop in late hours so this brightness issue is a big trouble for me Smiley Sad

Hi No_one,

 

Welcome to Lenovo Forums.

 

As i understand that you are unable to change the brightness on your Lenovo yoga 2 13, i would suggest you to go to the device managerà click on monitor  right click on the PnP monitor and see if it’s enabled.

 Hope the above information helps and please let us know how you go about.

 

Please feel free to post in Lenovo Community Forums if you have any further queries!

 

Regards,

Rameez

Hi, unfortunately I still have the problem. I really appreciate the guys who replied and gave me solutions above but nothing worked for me. I've tried so many things that didn't work. I started thinking about getting a new laptop. I really used to like my lenovo. I hope u find the solution, and if u do PLEASE tell me how. Good luck :')

Re: Yoga 2 13 Windows 10 Can't adjust brightness (Missing all brightness controls)

Hello everyone! I'm so glad that the problem was solved! Today, I suddenly noticed that the brightness changed when the battery went down. I immediately checked my brightness keys on the keyboard .. they worked! I also checked and saw that all brightness controls are back (in the action center as well as in control panel). I think that one of the recent Windows 10 updates has solved the problem. A lot of updates came in last month, so I'm not really sure which one of them solved it. Anyway, I can't describe how I feel right now! I really want to thank you all for your replies and suggestions. Thank you Smiley Happy
