** Description changed:

  Hello,
  
  I am a laptop user with 5900HX and RTX3080 Mobile. Today I noticed that
  psensor keeps my dGPU awake. When I close psensor I become able to see
  "D3Cold" in the power state of the GPU. Similar to this "nvidia-smi"
- command wakes up the dGPU. It took a lot of time to find the root of the
- problem. I think dGPU temperature measuring shouldn't wake the device or
- keep it awake.
+ command wakes up the dGPU.
  
  To repeat the problem:
  - Install psensor. Set up start on boot.
  - Select "On-Demand" from Nvidia Settings. (So dGPU should be enabled when 
requested)
  - Restart.
- - Run "cat /sys/bus/pci/devices/0000:01:00.0/power", output shows "D0" 
instead of "D3Cold"
+ - Run "cat /sys/bus/pci/devices/0000:01:00.0/power_state", output shows "D0" 
instead of "D3Cold"
