XPS 9720 with RTX 3060 GPU - Drawing 19-20W of power when idle?

I'm desperately hoping that somebody can help me resolve this inexplicable problem.

I recently picked up an XPS 9720 with the i7-12700H processor and a RTX 3060 GPU running on Windows 11.

I was surprised to find that my battery life was extremely poor, topping out at only two and a half hours while the computer was running completely idle. I'm serious: I was doing absolutely nothing, and the machine was burning through power.

To determine the cause of the problem, I downloaded HWiNFO to figure out where the power draw was coming from.

I was shocked to find the RTX 3060 was drawing a ridiculous 19-20W of power when completely idle.

I have tried virtually everything to troubleshoot this:

• I have entered the NVIDIA Control Panel and set my Global settings to Integrated Graphics.

• I have entered the Windows Graphics settings and disabled Hardware-Accelerated GPU Scheduling.

• I have updated all system drivers and the BIOS to the most recent version.

• I have entered the Windows Graphics settings and enabled power-saving for many of my most intensive applications.

• I have enabled the NVIDIA GPU Activity Notification icon and confirmed that the GPU is not active.

• I have installed both the Game Ready and the Studio drivers, with no difference using either one.

• I have disabled and re-enabled the graphics driver, with no difference before or after doing this.

• I have disabled visual effects in Windows 11 (including transparency and animations).

• I have checked the Task Manager to confirm that none of the processes are using the GPU, and confirmed that they are not.

This issue is going to make me tear my hair out, because my brand new machine is literally burning through battery life while running completely idle because of the RTX 3060.

Why the heck is this card pulling so much power while I'm doing absolutely nothing? Does anybody have any kind of solution to this?
