    THIS FINALLY FIXED IT FOR ME!!!!!

    I was able to disable adaptive brightness from cmd and right when I disabled it my screen lit up!!

    Open cmd and type this in:

    1. To Disable - On battery:

    powercfg -setdcvalueindex SCHEME_CURRENT 7516b95f-f776-4464-8c53-06167f40cc99 FBD9AA66-9553-4097-BA44-ED6E9D65EAB8 0

    And press enter

    1. To Disable - Plugged in

    powercfg -setacvalueindex SCHEME_CURRENT 7516b95f-f776-4464-8c53-06167f40cc99 FBD9AA66-9553-4097-BA44-ED6E9D65EAB8 0

    1. To apply changes:

    powercfg -SetActive SCHEME_CURRENT

    And press enter!

    If you want to toggle back adaptive brightness on, change the the last 0 to 1.

    Disable Adaptive Brightness??? This thread was supposed to be that ITS MISSING altogether since 1809 and WE WANT IT BACK.

    And ROLLING back the Intel Driver DOES NOT WORK. Neither does doing a clean install.

    I just sent ANOTHER request to Feedback Hub after a LOT of Updates to Windows this week. 

    And I included this snips>>

    IF ANYONE KNOWS HOW TO GET ADAPTIBE BRIGHTNESS BACK - PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!

    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

    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.

    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.
