Nvidia on Hybrid laptops while on battery goes to D0 state randomly wasting battery life

[stoneflesh0]

I have spent too much time trying to figure out, why does my nvidia gpu keep waking up when nothing is triggering it when on battery. When the laptop is plugged in to power, it doesn't randomly wake up the Nvidia GPU.

How to reproduce:

1. Nvidia-open installed
2. unplug charger
3. wait
4. notice the nvidia gpu waking from d3cold into d0 after 15 seconds (?) it goes to d3cold
5. wait (for 1-2minutes)
6. nvidia wakes up and repeats the pattern

The Nvidia DGPU also always wakes up when charger is plugged in or removed and when power profile is changed. Maybe these are all related?

I really care to have this fixed. As I have two laptops (G16 with rtx4080 and G14 with rtx4060) and both laptops have this issue.

I have accidentally found this issue #860 Maybe this is the issue as others also complain about the same. There is no solution provided. Is it possible to get this solved?
