Gnome - Different Brightness Level when Plugged and Unplugged the AC Power

Recently I just annoyed that my laptop always changes the brightness level when plug and unplug the ac power.

Turn out this is because Gnome power management save different values when we changes the brightness level using Fn + Brightness or brightness slider.

Let say when the AC power plugged and we set the brightness level to 100% and then we unplug the AC power and change it to 75%.

Now each time we plug the AC power the brightness level will be 100% and if we unplug the AC power the brightness level will be 75% as the last value we set on each both state--on battery or on AC power.

Bit annoying, but also useful enough.
