            Bug ID: 374901
           Summary: Battery indicator shows red icon warning 0% all the
                    time on desktop
           Product: kde
           Version: 4.14.1
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: Vasilis.Vlachoudis at cern.ch
  Target Milestone: ---

On my desktop computer with Fedora-25 (also in fedora-23 was similar) the
battery indicator on the status bar flashes constantly with a red icon and
shows a message "0% Plugged in, not Charging"
The only devices that I have with batteries are the APC ups and an Apple
Wireless keyboard. When I click the icon it displays two entries 
"Apple keyboard with battery level 33%"
and an additional entry "Battery not present"

In Fedora-23 I could eliminate the red warning by restarting the
upower.service. Not any more in fedora-25

The upower reports the following:

The ups for some reason appears twice as ups_hiddev0 and as DisplayDevice, but
both reported fully-charged, however the updated time for the ups_hiddev0 as
updated in 1970 (0s unix time), on the Display entry is correct.

Most probably there is a problem either with upowerd or apcupsd, but why kde is
reporting 0%?
