Hi,
Thanks reporting this problem you encounter.

In order to deal with it, could you produce a screenshot of the problem using spectacle (Mageia => Tools => Spectacle) as you are on Plasma. Add it on this bug report.

Also, could provide Mark, Model of the Notebook PC, and if they exist some references on the battery enclosure.

Have you ever tried Mageia 8 Beta 1 live ISO in order to know if planned new versions of softwares function well?

Source RPM: (none) => powerdevil-5.15

Battery model, 2 are visible:

N750BAT-4
6-87-N750-41D00

Computer model:

Clevo NJ50CU

I can see battery level with Mageia 7.1 GNOME & with Mageia 8 beta1

Thanks again helping identify the problem by providing a screenshot.

Seems to be in plasmoid that bug occurs.

What about "Batterie et luminosité" applet in systray? Does it show status when your system is plug on AC? Or only on battery? Does it provide useful informations or nothing?

In such case, could you provide an additional screenshot of this applet?

Summary: Can't see batterie level => Battery Plasmoid can't see battery level in Plasma wrongly says "Any battery found"
Source RPM: powerdevil-5.15 => plasma-workspace-5.15 powerdevil-5.15

I can't see status when my system is plug on AC.

That only useful information i have, is when battery is under 10%

That is reassuring is that your Mageia 7 system DOES see a battery. But you as user do not have a percentage nor time remaining before battery will be empty.

Does acpid.service is running?

$ systemctl status acpid.service

Also, what does following command give?

 $ upower -i /org/freedesktop/UPower/devices/battery_BAT0

acpid.service is ok:

That's ok too

So your battery is well know by under-the-hood tools.

You are encouraged to upgrade to Mageia 8 as soon as possible.

@reporter, if this bug still apply with Mageia 8, please let us know it.

@packager, if you work on the Mageia 7 version of your package, please check the Mageia 8 package if issue is also present. In this case, please fix the Mageia 8 version instead.

This bug report will be closed OLD if there is no further notice within 1st September 2021.

Hello,
