Why is my Laptop Nvidia card limited in Power Limit?

Graphics / Linux Linux
1

My Laptop is rated to run at 140W max for the graphics card I have. This was advertised when purchasing the product. Yet the limit is set to 115W. Apologies if it’s been already discussed and solution is crystal clear, it’s just not enabled by default for a common folk like myself.

There are guides online suggesting to enable nvidia-powerd service which enables DynamicBoost. I have done that, yet the power cap remains. Even whilst running games, it will not go above 115W

This appears to be only Linux case after noticing it’s not giving the same performance as Windows.

Is this a known bug? Is there an issue I can follow? I am running Arch

Update, installed sudo pacman -S power-profiles-daemon on Arch and enabled Performance mode using FN+Q on Lenovo Laptop. This brings the wattage to 140W while in Game. I also have nvidia-powerd enabled.

I use KDE so when installing power-profiles-daemon you get a new widget, but changing the mode via widget doesn’t seem to change anything. Only using FN+Q shortcut.

Using KDE 6.0.1

This is resolved Thank you :)
