Laptop Display Automatically Changing Brightness of Screen

On some built-in laptop screens, power settings can cause the screen brightness to change automatically to conserve power.

To stop this from happening, follow the steps below:

To Disable Display Power Saving Technology in the Intel® Graphics Command Center:

1. Open the Intel® Graphics Command Center
   • Press on the Windows key  on your keyboard and start typing Intel, choose Intel Graphics Command Center. 
2. Select System > Power
3. In On Battery, set Display Power Savings to Off

To Disable Display Power Saving Technology in the Intel® Graphics Control Panel:

1. Open Intel® HD Graphics Control Panel
2. Select Power
3. Select On Battery
4. Disable the Display Power Saving Technology (Intel® DPST)
5. Set Graphics Power Plan to Maximum Performance
6. Save changes and exit.

If this doesn't resolve the issue, contact the hardware device manufacturer for support.

Disabling Change brightness automatically when lighting changes in Windows Display settings may also resolve issues with automatic brightness.

If this setting does not appear, we recommend contacting Microsoft Support or your system manufacturer for information on how to disable the Adaptive Brightness. Adaptive Brightness is a setting provided by Windows that  uses an ambient light sensor in the system to automatically adjust a display's brightness to the surroundings.
