On my desktop pc the battery icon is always red with a ac plug in it. The tooltip always says 0% charging. If I click on it, the popup shows the two batteries of my mouse and keyboard correctly. Reproducible: Always Steps to Reproduce: 1. Look at the battery icon. Actual Results: Battery icon is always red and says 0% charging. Expected Results: Battery icon should recognize that the system is a desktop pc without battery.

The icon is hidden in the popup, right? If so then it behaves as intended.
Actually not, the icon is always visible in the panel (see screenshots). If this is the intended functionality, I see two problems: 1. Displaying always a red icon is misleading and suggests to the user, that there could be a problem which should be taken care of. 2. The tooltip saying "0% Wird geladen" (this is german, in english "0% charging") is misleading, too. Would it be possible to think about the intended behaviour again and find maybe some other way of visualization?

You're right, the battery monitor should hide in the popup and the tooltip should reflect the missing battery. Can you have a look at the "powermanagement" dataengine using plasmaengineexplorer (part of plasma-sdk)? Look in the "Battery" section (not Battery0) and see what it says for "Has Cumulative". It has two properties, one "Has Battery" which is whether there is any battery at all (your mouse/keyboard), and "Has Cumulative" whether there is a battery actually powering the device. Okay, I found the issue for the tooltip: The thing just checks if (batteries.count == 0) instead of the "Has Cumulative" property and then it says "x% charging". The mystery is now why the applet did not hide itself in the popup automatically, according to your upower output both devices correctly report "power supply: no".
Please see attached screenshot for the output of Plasmaengineexplorer. I think that the reason for the always shown icon is my configuration, so maybe no mystery here. According to the settings in System Tray Settings the respective entry for powermanagement is set to Shown (which is what I want, by the way). But still one question: Is the red color on purpose on not? As already mentioned, in my opinion it should not be colored red as it is misleading.

Thanks a lot. Ah, that explains why it shows up. :) I'll fix the tooltip but not sure about the icon. Perhaps have the icon black instead of red in your case?
Created attachment 98910 [details] Fix tooltip and icon If you can, please test this patch, it will show "No batteries available" if there are none whatsoever and the generic "Battery and Brightness" title when there are only mouse/keyboard like in your case. It will also change the icon to instead show a red outline to show a black outline with a superimposed "X" as "Batteryies unavailable" which should draw less attention to it.

Thank you very much for that really fast fix! The screenshot looks good! And sorry for my late reply!
