I think there's a syntax bug in original code regarding ideapad?

System information:

Add/paste output of:

-------------------------------- Battery Info ---------------------------------

battery count = 1
ERROR: failed to read battery thresholds: [Errno 2] No such file or directory: '/sys/class/power_supply/BAT0/charge_start_threshold'

-------------------------------------------------------------------------------

Linux distro: Arch Linux rolling n/a
Linux kernel: 6.6.45-1-lts
Processor: 12th Gen Intel(R) Core(TM) i5-12500H
Cores: 16
Architecture: x86_64
Driver: acpi-cpufreq

Also please be descriptive about the issue you're reporting, i.e: what you tried & what's the expected behaviour.
I'using ThinkBook. It's more or less rebranded IdeaPad but not exactly, so it uses idea_pad module but doesn't support threshold. Thus, it triggered auto_cpufreq/battery_scripts/ideapad_laptop.py but failed at:

 try:
            with open(f'/sys/class/power_supply/BAT{b}/charge_start_threshold', 'r') as f:

It should work nonetheless as there is exception catch. However, the original code:

except Exception:
            print(f"ERROR: failed to read battery thresholds: {e}")

doesn't seem quite right and should be changed to:

except Exception as e:
            print(f"ERROR: failed to read battery thresholds: {e}")

---

I install auto-cpufreq from AUR, but I do see other thinkbook users have the same error in issues. I think this just a small syntax bug?

@Qianxilihulu What's your laptop model and can I have the output of
lsmod.

[AdnanHodzic]

Is this the same issue which was fixed in #750 as part of #766 @Geffo029?

If yes, then simply git pull the latest changes and run --install with auto-cpufreq-installer followed by auto-cpufreq --install

[Geffo029]

No, the error

except Exception:
            print(f"ERROR: failed to read battery thresholds: {e}")

(forgot to add as e to except Exception) was fixed in #696 (i manually checked from file history, i don't know if there is a better way to check).

Could you please create a new PR regarding this, since you're also using Ideapad?

I'm new to this things so maybe there is something i'm not understanding.
The issue shown was already fixed, but after the release 2.3.0 in May 9. So if you install auto-cpufreq from AUR, where the PKGBUILD refers to v2.3.0, you miss the fixes

[AdnanHodzic]

In that case I'll tag @MusicalArtist12, @liljaylj and @parmjotsinghrobot

[Qianxilihulu]

AUR 2.4.0-1 seems to fix this problem so I'll close this issue
