stuck tray widget
SUMMARY
After unplugging a laptop from its charger battery monitor widget in tray stays
stuck on the charging state. Everywhere else I have been able to look, the
system is reporting discharging. This includes the menu which pops up by
clicking the widget. Picture of this is attached.
The real problem is that this somehow disables all notifications about low
battery power and more importantly prevents the laptop from hibernating when
the battery is almost depleted and hence can cause serious data loss and it
also puts a lot of strain on the battery itself. The only way I have been able
to temporarily reset the state shown in the icon is a reboot.
STEPS TO REPRODUCE
1. plug a charger to a laptop
2. wait for a while
3. unplug the charger
OBSERVED RESULT
Battery widget shows "charging" even though the charger is not plugged and more
importantly the system behaves as if the charger was plugged in.
EXPECTED RESULT
Battery widget shows "running on battery". System notifies about low power and
takes action according to it.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Debian Bullseye and Manjaro
(available in About System)
KDE Plasma Version: 5.17.5 and 5.19.5
KDE Frameworks Version: 5.70.0 and 5.74.0
Qt Version: 5.14.2 and 5.15.1
ADDITIONAL INFORMATION
The problem does not always appear instantaneously. When I start the system
unplugged, everything is fine. If the charger is plugged in and in a matter of
seconds again unplugged the system mostly behaves as expected. But when left to
charge for a while the power management state gets stuck, always. Notifications
are set and working in the case of unplugging the charger immediately. The
change of the state is known to the widget for while it is hidden while
charging when the charger is unplugged the widget appears.
I have found two other people mentioning the same problem:
https://forum.manjaro.org/t/battery-icon-is-constantly-in-charging-mode/27605/8
and
https://www.reddit.com/r/kde/comments/ey39zg/the_battery_indicator_icon_is_frequently_stuck_on/fgf01ud/
with no solution.
I have also experienced this issue on multiple systems. My laptop is running
Debian Bullseye (currently testing) with KDE Plasma 5.17.5. While this version
is not very old it is not very recent either and for this reason I have
downloaded current Manjaro with KDE and confirmed the issue is also present in
this system which is running on KDE Plasma 5.19.5. In this case the system was
running as live session from a bootable usb. Another laptop running Debian
stable with KDE Plasma 5.14.5 does not have this issue.
While I have not tried the very last version od KDE Plasma I did my best to
check the changelog summary and haven't found anything like this. I also
believe that at least the version 5.19.5 is recent enough.
