How to Change Power Limit for Nvidia GPU on Laptop

I'm using a 3060 mobile GPU, and I know that the power limit change is blocked on laptop after 53x.xx driver update. I would receive messages like

Changing power management limit is not supported in current scope for GPU: 00000000:01:00.0.

if I run

sudo nvidia-smi -pl 25

Since newer drivers offer better performance, is there any way to bypass this limitation without downgrading the driver?

Re: How to Change Power Limit for Nvidia GPU on Laptop

Enable and start nvidia-powerd.service and if you use tuned or ppd set the profile to balanced or performance, if your laptop is Lenovo Legion you should also set its (Fn+Q) performance mode. After that, your GPU's TDP should scale with load. At idle nvidia-smi will tell you that 80/115w is the limit, but under load it can go up to 140+ depending on your device.

Really sorry for my action. I'm not so familiar with this forum, so I just clicked the report button blindly and without seeing the title, entered the content I'd like to post under your reply. I'm very sorry for what I did.

What I really wanted to say:
I found online that nvidia-powerd.service is used to support dynamic boost feature. However, what I actually want to do is lower the power limit, not increase it.

Don't worry about the report, it happens lol smile I almost did the same thing once.
Unfortunately, there's no way to explicitly limit GPU performance like there used to be, and Nvidia is quiet about this problem. I guess if you want to limit the power consumed by the GPU, you can try adjusting the clocks

But is there any possibility that I can "mod" the driver to let it support the -pl option on laptop?

I think it would be possible to do that with nvidia-open, but I can't say for sure

Can I leave this thread open since there's possibility that someone may have solution?

Yes, that's the right thing to do
