Description redford 2024-12-05 14:07:43 UTC

SUMMARY

When opening the "Power Management" applet the UI doesn't indicate any problems, but `plasma-powerdevil.service` logs the following:

org_kde_powerdevil[1633]: org.kde.powerdevil: org.kde.powerdevil.chargethresholdhelper.getconservationmode failed "Battery conservation mode is not supported"

OBSERVED RESULT

Error logged but not displayed in the UI.

EXPECTED RESULT

Ideally no error happening at all, or at least some indication in the UI that setting some settings failed.

SOFTWARE/OS VERSIONS

KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0
Kernel: 6.12.1-arch1-1 (64-bit)
Device: ThinkPad P14s Gen 5 (AMD) 21ME

ADDITIONAL INFORMATION

Setting stuff manually in /sys/class/power_supply/BAT0 seems to work correctly, so I'm not sure what exactly is causing the error.

I can help in debugging, I know low-level stuff and gdb, but I'm very new to KDE and Arch, so I'll need help with that.

This not really an error, it just means this particular hardware feature is not available.

The message is slightly misleading

But if it's not available, then the UI should not allow using it? There's no indication that it's not actually working.
Also, I'm able to set stuff in /sys/class/power_supply/BAT0 manually, so it seems that it does actually work? What does this message in the logs means, exactly?
