Brightness Stuck at Either 100% or 0% in Windows 10.

This issue
has been posted about before. I am having the same issue, but have noticed that my brightness is stuck at 100% or 0%. It seems to stay wherever it was set when it rebooted. I am about to see if it stays at 50%

I have tried:

• reinstalling (deleting the driver files) the video driver.
• Setting the brightness to 0 & rebooting

 

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.

 

Brightness resets after reboot

Hi Marc,

In addition to the troubleshooting step that you have already done, we suggest that you try disabling the adaptive brightness from your PC. Follow the steps below and see if it resolves the issue:

• From the Search bar, type Power Options.
• Click Power Options from the result. Under Preferred plans, click
  Change plan settings.
• Click Change advanced power settings and select Enable adaptive brightness to turn it
  ON or OFF.

After saving the changes, restart your PC and check if issue still occurs.

Let us know how it went.
