Windows 10: Power plan brightness setting gone in Windows 10 1809

Hi,


I have three notebooks with Windows 1809(one upgraded from 1803 and two clean installs).


In previous versions we would have "Adjust plan brightness" option in Control Panel->Hardware and Sound->Power Options->Edit Plan Settings.


The brightness you adjust by hot key/Windows Mobility center/Modern UI setting is still remembered.


But you cannot change it in power plan settings.(You can't see plan brightness in Advanced power settings window either.)


1803 and older:



1809:

Power plan?

Upon checking, it seems that there's nothing wrong with your system. It is usual that you have to double-click your mouse before your monitor wakes up.

For the meantime, we suggest changing the power plan by following the steps below:

• Press Windows key + S.
• Type in Power Settings.
• On the pop-up window, choose Additional power settings.
• Select High performance.

After changing the power plan, we suggest that you monitor the changes made and check if that will work for you.

Get back to us if you need further help.

 

Brightness automatically changes in Windows 10

Hello Pam,

We regret for the inconvenience. Let me assist you to resolve the issue.

In this scenario, for us to be able to understand the issue better, let us know the make and model of the desktop you are using.

Also, do you have any active Power plan you have set in Windows?

As an initial recommendation, I suggest you to follow the below steps to
disable the adaptive or auto brightness for the selected power plan (if you already have a Power Plan created in Windows).

• Open Control Panel and click on Power Options.
• Open your active power plan, you’ll see Change plan settings option. Click Change plan settings next to your current power plan to open Edit Plan Settings window.
• Click Change advanced power settings option. This will open Power Options dialog.
• Expand Display and then expand Enable adaptive brightness. Change it to Off
  

Next, if you’re sure that the adaptive brightness or auto brightness is disabled on your PC, then it could be because your PC using Intel HD graphics, and the Intel power saver technology is trying to save some power by
automatically decreasing backlight intensity.

Note: You need to refer to the manufacturer provided manual for more information on how to access Intel Graphics Panel and its properties.

Write to us with the updated results and the required information for us to be able to assist you further.

Thank you.

Hi Jonah,

Thank you for contacting Microsoft Community. I understand that you have an issue with power plans.

This issue could have occurred due to incorrect Power settings. Try the steps listed here:

Method 1:

Let’s run the power troubleshooter and check if that helps.

c. Click on ‘System and Security’ and click on ‘Power’ click on next to run the troubleshooter.

If the issue persists, I suggest you to
restore the power plans to default and check if it helps.

Step 1: Reset and restore the power plans to default:

  Right-click on
  Start button and click on Command Prompt (Admin).
