I'm using Lenovo Legion R9000P2021H laptop,arch linux.
After I installed it from the AUR,I ran "sudo systemctl enable --now auto-cpufreq.service" to start the service.But it is completely broken and unusable.

Try installing with sudo auto-cpufreq --install instead

[PurpleWazard]

Also in your config file under battery change it to this

[battery]
enable_thresholds = false

[YXPD]

Have no effect.The same error.

[ArtemChandragupta]

I use NixOS unstable on ThinkBook13s g3. I had same error on old install three month before (before that auto-cpufreq --stats worked as intended), and got it now on fresh install.

By the way, seem that auto-cpufreq is working judging by improvement of battery life.

[AdnanHodzic]

[battery]
enable_thresholds = false

Can you please confirm you're still getting the same error after reboot? As you shouldn't see that output if indeed you did this. Could be worth pulling one of the AUR package maintainers, but I don't think this is a package issue.

After I installed it from the AUR,I ran "sudo systemctl enable --now auto-cpufreq.service" to start the service.But it is completely broken and unusable.

What is exactly completely broken and unstable?

[YXPD]

After I ran "sudo systemctl enable --now auto-cpufreq.service",the service started.
but whatever I ran --stats,--debug or --monitor I got the same python error just like the above one.(Is this a python version issue?)
As you said,I reboot,and here is what I got:

➜  ~ sudo systemctl status auto-cpufreq.service

8月 21 19:34:06 pod systemd[1]: Stopped auto-cpufreq - Automatic CPU speed & power optimizer for Linux.

It seems that the service failed to start,then I use journalctl to check what happened:

This is the journal before I reboot,it throws this error every seconds "echo: write error: Device or resource busy"
Sorry for the poor English.

Personally i solved both

could not get value from conservation mode

and

File "/usr/lib/python3.12/site-packages/auto_cpufreq/battery_scripts/ideapad_laptop.py", line 101, in ideapad_laptop_print_thresholds
    print(f"ERROR: failed to read battery thresholds: {e}")

by tweaking the file '/usr/lib/python3.12/site-packages/auto_cpufreq/battery_scripts/ideapad_laptop.py':

1. in my case the function subprocess.check_output("cat /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode", shell=True, text=True) at line 41 was returning '0\n' so have added value = value.rstrip() after that;
2. i have changed line 100 to except Exception as e: as mentioned in I think there's a syntax bug in original code regarding ideapad? #765

[PurpleWazard]

@Geffo029 it would be great if you could make a PR. im sorry i didnt get to it. with school starting, it been tight on time so id appreciate it.
