I rely heavily on Auto CPU Frequency in 21.10 for proper power backup.
Otherwise, I need to charge every one hour. And the UI that comes with Nvidia Graphics card disables it until next restart.
If I need to use Blender and need GPU support, I have to go through a full restart cycle.
I have no option but to keep the graphics card disabled if I need to use the laptop for a few hours.
It would be nice to see options to make battery backup better if possible.
