This happened to me several times since the Fedora 40 KDE beta (on an x86 laptop), but hasn’t happened for at least 3 weeks now. I’ve never found out what was responsible for this, but it seems to be gone.

Thanks for reply

It returned last week, Plasma reset the settings to 100% twice on my laptop. Also, the UX of the „percent fields” is terrible, it adds % in the middle of typing.

There is Bug 450551 tracking this. Right now Plasma assumes that the firmware will store this value across reboots, which is true at least for ThinkPads but not for all laptops. There’s been some attempts and discussion towards implementing this as a setting, but more work is needed to get the setting merged into Plasma proper without regressions or forward compatibility concerns.
