KDE Battery applet doesn't show the time remaining anymore

aliasbody · 2012-05-04 16:20:00

Hello Everyone,

I've been using KDE for 2 months and not a single problem, but yesterday (right before the update of KDE from the repositories), I noticed that the battery applet stoped displaying the time remaining.. Now it only show's the percentage of the battery (charging or discharging).

How can I solve this problem ?

PS : I tried to start the root account just the see if it was a bad configuration (without having to remove all the kde configurations), but nothing to do, even in the root session I wasn't unable to see the time remaining... Can it be a package that I need to install ?

Thanks in Advance,
Luis Da Costa

(Sorry for my horrible english :S...)

I'm not sure but I think the problem came from the update of upower... anyone know something about this ?

For those with the same problem this is how they can see the battery time remaining until the problem is solved :

In the terminal type this :

upower --enumerate

It will output something like this:

/org/freedesktop/UPower/devices/line_power_AC0
/org/freedesktop/UPower/devices/battery_BAT0

The battery is the one that says BAT0... after that, you just have to do the fallowing to know all the informations about it (just change the path on the end of the line):

upower --show-info /org/freedesktop/UPower/devices/battery_BAT0

And you will have something like this :

  native-path:          /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/PNP0C0A:00/power_supply/BAT0

    1336148581  12.377  discharging
    1336148551  12.876  discharging

For a more especific information you can do this :

upower --show-info /org/freedesktop/UPower/devices/battery_BAT0 | grep "time"

And it will output something like this :

time to empty:       1.5 hours

Hope this helped ^_^ (the problem with the kde battery applet is still here thought :S..)

I got the same problem, hopefully this will be fixed soon.

Depending on your model, you can use "acpi -V" to show remaining time.

I've had this problem too. I disabled systemd and the problem is gone. Blame it on systemd.

Same problem here, but no solution...

The problem is known and seems to be solved (https://bugs.kde.org/show_bug.cgi?id=290578), but the solution (updating to KDE 4.8) didn't work for me.

Reinstall upower (pacman -S upower) since /usr/lib/systemd/system/upower.service seems to be missing!
It fixes the problem for me!

Schrottfresse · 2012-06-06 05:00:12

Done, but did not work for me. :-(

Same problem here:(

Schrottfresse · 2012-07-13 07:23:36

Found a solution:

Since my device notifier in the system tray disappeared, i removed the system tray from the taskbar. After i reinstalled it, the device notifier was back and the battery applet showed the remaining time again.

It works! Thanks!

The issue appeared again:(

EDIT: Solved, with inserting "showRemainingTime=true" after "showBatteryString=true" in "~/.kde4/share/config/plasma-desktop-appletsrc".
