Brightness not working on Windows10.

Hi ,

On my Dell 5559 Windows 10 , brightness not working.

Have tried few steps from youtube videos but did not work.

Please guide.

Thanks.

 

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

Hi Ella,

To adjust the brightness, see the steps below:

• Go back to Power Options, and tick on the High performance.
• See if you can adjust the brightness.

If this not work, we highly suggest that you create an Administrator account, and re-do the steps above.

Let us know how it goes.
