screen brightness on windows 10

Hi,

Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

To manually adjust the screen brightness, we suggest following these troubleshooting steps:

• Click Start, then select Settings.
• Choose System, then select Display.
• Under Brightness and color, move the Change brightness slider to adjust the brightness.

Feel free to post back if you have other concern.

 

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.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

 

Missing Adjust Screen Brightness slider in Power Options

My HP laptop performed a Windows Update today. As a result, I've lost my "Adjust Screen Brightness" slider in Power Options. I can still find it in Settings - Display.

I have Win 10. I've found a YouTube video (specifically for Win 7) that suggests going to Device Manager - Monitors - Properties - Uninstall Device, but I've also read that doing so will merely result in the same driver being reinstalled.

What should I do to get the "Adjust Screen Brightness" slider back in Power Options?

Thanks so much for your help.
