Hello,
For at least a couple of months now there has no longer been a brightness control slider to individually control the brightness when on battery or when plugged in when you go to Control Panel\All Control Panel Items\Power Options\Edit Plan Settings.
However, until about a week ago I could still adjust the two separately by unplugging the laptop, use the keyboard shortcuts to adjust my brightness to what I wanted for battery and then when I plugged it back in it would switch back to the brightness for being plugged in. Similarly unplugging it, it would automatically switch to the level I had it set to when I was last on battery. I am not sure, but I think this also worked by using the slider in the notification side bar.
Since the most recent windows update (the one that revamped Microsoft edge and I needed to reset my start up pages among other things) this no longer works. I will also say that I am not confident about which version of Windows 10 I'm currently on. Settings/System/About it says I'm version 1909. If I go to Settings/Update & Security it says I'm up to date which I understand should be version 2004???
Things I have tried:
Does anyone know if those sliders were supposed to have disappeared and if there is anything that can be done to get them back?

Things I have tried:
- Made sure my nvidia drivers were up to date
- Made sure the drivers for the Generic PnP Monitor are up to date. If I automatically search for new drivers it says the current drivers are fine though they are from 2006.
- Disable/re-enable Generic PnP monitor
- Removed Generic PnP monitor that was hidden under monitors. I went to view and selected show hidden devices to be able to do this. This was suggested here.
- Followed this tutorial to change the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\aded5e82-b909-4619-9949-f5d71dac0bcb from 1 to 2. I realized the tutorial says that this didn't work since version 1809 but I thought I would try it anyways. It need have the effect of adding an option to advanced power settings/display for adaptive brightness control but was reset as soon as I restarted windows.
- Did a registry search for the key EnableBrightnessControl as per an answer posted here. It was not found.
- Also tried this fix that explained how to edit registry DCSettingIndex. However I get an error message saying "Cannot edit DCSettingIndex: Error writing the value's new contents". I was running regedit as an administrator.
Does anyone know if those sliders were supposed to have disappeared and if there is anything that can be done to get them back?
