Bug ID: 415597
Summary: "No Batteries Available" despite detecting a battery
Product: Powerdevil
Version: 5.17.4
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: thi...@kde.org
Target Milestone: ---
SUMMARY
The power/battery icon in the system tray is always displaying a full, black
battery instead of a discharging one when I am on battery power. If I hover it,
it says "No Batteries Available". If I click it, it shows the sliders for
keyboard and screen brightness, but no information about the battery.
OBSERVED RESULT
Powerdevil does not display information about battery. However, it does detect
when I am connected to the AC or not.
EXPECTED RESULT
Powerdevil tells me how long I have of battery life.
