Bug ID: 504085
Summary: Brightness & Batteries widget erroneously says "No
Batteries Available"
Classification: Plasma
Product: plasmashell
Version: 5.27.12
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Power and Battery widget
Assignee: plasma-b...@kde.org
Reporter: c6kargn...@liamekaens.com
CC: k...@privat.broulik.de, natalie_clar...@yahoo.de
Target Milestone: 1.0
SUMMARY
The Brightness & Batteries widget can get into a state where it doesn't show
any battery-related information, despite the system being a laptop which
definitely has a battery. In this state, other parts of the system still
respond normally; for instance, when switching to/from battery, the
corresponding system notifications are generated.
STEPS TO REPRODUCE
1. I don't know what caused it to start doing this.
OBSERVED RESULT
Hovering over the Brightness & Batteries system tray icon displays a pop up
which states, "No Batteries Available".
EXPECTED RESULT
The popup should show the laptop's battery and its current state.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Ubuntu 24.04.2 LTS
KDE Plasma Version: 5.27.12
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.13
ADDITIONAL INFORMATION
`upower -e` lists the battery, and `upower -d` lists detailed information about
the battery.
`dbus_monitor` shows events being raised when the battery switches to/from a
charging state.
Info Center lists the battery details and its current state.
Only the system tray icon seems to be affected.
This is not corrected by rebooting the system.
