Gaming Notebooks

Hello,

I’m fairly new to Linux (Ubuntu), so please forgive me if this question seems basic — I’ve done my best to provide all the details.

I recently got an HP OMEN 16 MAX laptop with an RTX 5070 Ti Laptop GPU and an AMD Ryzen AI 9 375HX processor.
Everything works well, but I’ve noticed that my GPU is permanently limited to 80W, even though its hardware and firmware clearly support up to 140W.

When I check the GPU power limits on Ubuntu 24.04.3 LTS using nvidia-smi -q -d POWER, I get the following Power Readings

Current Power Limit : 80.00 W

However, when I try to increase it:

sudo nvidia-smi -pl 140

I receive:

Changing power management limit is not supported for GPU: 00000000:C2:00.0.
Treating as warning and moving on.
All done.

Things I’ve tried:

• Updating the BIOS from F.02 → F.04 (latest but same result)

• Installed NVIDIA driver 580.82.07 

• Using the official 330W HP power adapter (always plugged in, battery typically above 90% different outlets and building tried  same result)

• Verified that OMEN Gaming Hub on Windows allows higher GPU power modes (110W+), but there’s no similar control under Linux

Performance observations:

Interestingly, even with the 80W cap, I get around 170,000 points on Geekbench 6.5.0 (OpenCL test), which is surprisingly similar to the Windows results reported for the same laptop which should have the higher power limit thanks to the HP Gaming HUB
I've already tried on the Driver to change the preferred power mode to Prefer Maximum Performance 
but i got no change and my laptop is always on Power mode Performance

System details:

• Laptop: HP OMEN 16 MAX

• GPU: NVIDIA RTX 5070 Ti Laptop GPU

• CPU: AMD Ryzen AI 9 375HX

• BIOS: F.04

• OS: Ubuntu 24.04.3 LTS

• Kernel: 6.14.0-33-generic

• NVIDIA Driver: 580.82.07

• CUDA Version: 13.0

Question:

Is there any way to unlock or enable the higher GPU performance modes (above 80W) on Linux, without relying on OMEN Gaming Hub for Windows?
Or could a firmware or BIOS update be released in the future to allow this?

I am frankly out of option at this point so your help would be greatly appreciated

Thank you so much for your time and help!
