Windows 10: Screen brightness won't adjust on latest Windows 10

I have a Dell Venue 8 Pro 5830,

I upgraded to the latest Windows 10, and the brightness can no longer be adjusted,

On the previous version, it worked without any flaw,


Is there a way I can fix this or downgrade to a previous version?

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.

 

Adjust Screen Brightness and Resolution in Windows 10

The screen brightness adjustment keys of my HP Pavilion laptop are not recognized by Windows 10. It is so bright that it is harming our eyes. Also, I followed the suggested alternate steps from many websites and none of them worked as the brightness adjustment
option is not at all available even not inside Control Panel.

Please note that before installing Windows 10, I got notification that my laptop is compatible for the upgrade. Can you please help?
