As I expected upower reports a battery-powered tablet with the name "ELAN Touchscreen Stylus". This is most likely an implementation detail of your touchscreen hardware. In that sense Plasma works as expected, it correctly shows the data exposed by upower. That said, I understand that reporting this as a battery doesn't really make sense. You can report this to https://gitlab.freedesktop.org/upower/upower/-/issues, but I'm not sure if upower is necessarily the right place to fix this or this is a kernel/driver issue. See https://gitlab.freedesktop.org/upower/upower/-/issues/197 for a similar issue (In reply to Nicolas Fella from comment #4) > Thanks! > > As I expected upower reports a battery-powered tablet with the name "ELAN > Touchscreen Stylus".

Created attachment 186209 [details] Screenshot of system tray battery pop up SUMMARY When clicking on the battery icon in the system tray, it shows information about a ELAN Touchscreen Stylus. I don't know if this refers to a stylus pen or not, either way I don't have one. STEPS TO REPRODUCE 1. Click on the battery icon in the system tray; 2. A ELAN Touchscreen Stylus battery entry is present there; 3. If I open information center and then click on Energy, the same ELAN Touchscreen Stylus entry is there along with the internal battery. OBSERVED RESULT A ELAN Touchscreen Stylus battery entry is present in the system tray and in the Information Center application. EXPECTED RESULT There should not be information about non existent battery for the screen, in the system tray (see attachment). SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Linux KDE Plasma Version: 6.5.80 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.0 ADDITIONAL INFORMATION I'm using an MSI laptop that has a convertible screen with touch.
