After installing `power-profiles-daemon` by calling `sudo pacman -S
power-profiles-daemon`. Following happens:

- We presented with new widget
- New performance mode is unlocked (which was not here before). For example,
before installing the package and pressing `FN + Q` - keyboard shortcut to
change power mode. We only have `White` and `Blue` colours. With package
installed, we also have Red mode.

Lenovo laptops have these power modes. Fn + Q to cycle between blue (Quiet),
White (Auto or Balanced), Red (Performance).

Keyboard shortcut works great now, however if you attempt to change power mode
via widget slider, it does not affect anything, the power limit wattage stays
the same and hardware colour on power button stays the same.

STEPS TO REPRODUCE
1. `sudo pacman -S power-profiles-daemon`
2. `sudo systemctl enable --now power-profiles-daemon`
3. restart computer
4. navigate to widget and change to any mode
5. observe in `nvtop` power limit has not changed and stays the same
6. Manually press `FN + Q` on keyboard as a shortcut for Lenovo laptops to
change power mode. This will change wattage limit, and change hardware colour
on your power button

OBSERVED RESULT
Widget slider for power change mode does not do anything

EXPECTED RESULT
Widget slider changes power limits accordingly and changes the colour of
hardware power button
