Power Source: Undersized

Hi, I have my Laptop MSI GT73EVR-7RF with Arch Linux 6.4.12-arch1-1 and the GPUI GeForce GTX 1080: NVIDIA-SMI 535.104.05 | Driver Version: 535.104.05 | CUDA Version: 12.2.


Problem:

Everything starts up fine and I have close to 200W maximum power capacity. The parameter “GPUPowerSource = 0” which is AC.

If I disconnect the laptop from the electrical current, the parameter “GPUPowerSource = 1” which is battery. Going down to 45W maximum power capacity.

However, if I reconnect the laptop to the electrical current, it shows me the parameter “GPUPowerSource = 2” which is undersized, maintaining 45W maximum power capacity.

If I disconnect the laptop from the electrical current, again, the parameter “GPUPowerSource = 1”, keeps the maximum at 45W.

If I reconnect the laptop to the electrical current, the parameter is still “GPUPowerSource = 2”, it keeps the maximum at 45W.


PowerMizer
Power Source: Undersized
Default TGP: N/A
Max TGP: N/A


Command to read the GPU power supply:
nvidia-settings -q GPUPowerSource -t

The question is how to fix it. I mean, I would rather not reboot Linux every time the GPU go back to the undersized power. Furthermore, this problem happened if I got turned on the computer for a couple of days.

Do you know how to set / edit the GPUPoweredSource to 0 (AC power source)?
Or what fixes need to recognize the electrical power again?

Also having this problem on my dell g15 5530, but powermizer reports it as Error instead of Undersized.

Didnt managed to solve it yet.
