I’m on Debian Bookworm:
Linux wibble 6.1.0-20-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.85-1 (2024-04-11) x86_64 GNU/Linux
I have the latest Nvidia drivers, here’s output from nvidia-smi:

I tried running nvidia-smi -pl 20 - which reduces the max, but current still says “N/A”, and I see no difference at the wall.
Can anyone help please with getting this T1000 to the lowest P state, hopefully with the fan off?
