Hi,
I just installed Fedora 41 KDE on my new Thinkpad P1 and I noticed excessive power usage even though the laptop is at idle.
I am using auto-cpufreq (which is a brilliant tool) as well as powertop for analysis.
I use s-tui to monitor the actual power usage of the system and the weird thing is that the package uses 2.5 to 4 watts at idle while on battery and 6.5-8.5 when plugged, but the psys reports 10-14 watts while on battery and 16-20 watts when plugged.
The laptop has an RTX 4060 but it is not used for anything except compute, I can verify that using nvidia-smi which shows that the power usage is 1-2 watts.
Does anyone know what the cause is? What other parts of the system can use ~10 watts of power constantly?
