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.

 

Brightness Control not working in Windows 10

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.

 

Brightness is fixed/unadjustable.

If it was working previously, I'd bet it stopped due to a mirror driver being installed. Mirror drivers are what allow remote meeting software like GoToMeeting, WebEx, and Team Viewer to copy the screen.

Here's the steps I would suggest:

• Right-click the Start button, choose Device Manager
• Go to the Monitor section (not display adapter) and remove everything inside (right-click and uninstall)
• Click the "Scan for hardware" on the toolbar (has a magnifying glass icon on it)
• Try adjusting brightness again

Please let me know how it goes.
