    In Windows 10 Home Version 10.0.18363 Build 18363 this issue still exists. To be clear. The setting toggle is MISSING from the advanced power plan options.

    Steps to reproduce:

    1. Open Conrol Panel
    2. Select "Hardware and Sound"
    3. Select "Power Options"
    4. Select "Change Plan Settings" next to the currently active power plan.
    5. Select "Change advanced power settings"
    6. In Advanced settings under the Active power plan Click the + to the left of "Display"

    Result: In the expanded menu, the only option available is "Turn off display after"

    Expected: The options should read as follows:

    "Turn off display after"

    "Display brightness"

    "Dimmed display brightness"

    "Enable adaptive brightness"

    Attempted fixes: Changed display adapter settings. Changed adaptive display from command prompt.

    OK great, but how can you turn Adaptive Brightness On & Off is 1809 deleted it from your system and Windows NEVER put it back???

    and Yes.. rolling back drivers or doing clean installs does NOT fix that.

    It doesn't restore adaptive brightness to the power options, you're manually turning adaptive brightness on and off with that command. After you turn it on, cover the light sensor (which is usually by the webcam) with your hands and see if the screen dims automatically. If it doesn't your computer probably doesn't have a light sensor.

    Don't get me wrong... I really appreciate any and all help I can get to fix this issue, but the "original" topic here was that "Adaptive Brightness" was GONE after 1809

    I tried your suggestion BUt that does NOT restrore Adaptive Brightness to the Power Options in the device manager as above.

    No, the original question asked how to turn off adaptive brightness so that the brightness will be on 100% even on battery.

    Anyways if you want to turn it on use this command:

    1. To enable - On battery:

    powercfg -setdcvalueindex SCHEME_CURRENT 7516b95f-f776-4464-8c53-06167f40cc99 FBD9AA66-9553-4097-BA44-ED6E9D65EAB8 1

    And press enter

    1. To Enable - Plugged in

    powercfg -setacvalueindex SCHEME_CURRENT 7516b95f-f776-4464-8c53-06167f40cc99 FBD9AA66-9553-4097-BA44-ED6E9D65EAB8 1

    1. To apply changes:

    powercfg -SetActive SCHEME_CURRENT
