    Did not work even after reboot. The ability to set the time for dimming display when on battery is missing on 20H2.

    Hello mate,

    Do you mean that you have Dimmed display brightness for "Plugged in" (AC) but not for "On battery" (DC)? If so, do you have the DC setting for other power options?

    If you did not originally have the Dim display after setting available, then it means it is not supported on your computer. Instead, the display will automatically dim by the set Dimmed display brightness percentage exactly 10 seconds before the specified Turn off display after time.

    Thanks for getting back. Evidently I don't have the setting because I looked in BIOS and there wasn't anything for the display. I have the "Attributes" setting in registry and set it to 2 and it did not make any difference. I have a HP x360 with AMD display, will have to do some looking. Thanks again

    I just checked on my Surface Pro X tablet and HP x360, and I don't have the Dimmed display brightness option available either even when enabled.

    Now that is a coincident with both of us having the same PC.

    I was exercising my battery and wanted to extend the display time, suffer baby, suffer!
