--- Comment #3 from Markus <darkvis...@gmx.eu> ---
I can confirm this problem on a Lenovo Thinkpad Yoga12 with Slackware64-Linux
14.2/-current and KDE Framework 5.21/Plasma 5.6.3 and Application 16.04.0.
UPower is at version 0.9.23. Kernel is 4.6rc6.
Here is my output from upower --dump:
This is the output when the battery is not detected directly after i booted
into Plasma5:

There is nothing weird in the output. Also this does not happen on every boot.
Sometimes the battery is detected, sometimes not. This is what powerdevil
logged in .xsession-errors while battery is not detected:

Looks like powerdevil does know that it is on battery mode. Output from

Is there any other output/logfile interesting that i can check to provide more
information?
