SUMMARY

power button is hardcoded to always show as available https://invent.kde.org/plasma/powerdevil/-/blob/master/kcmodule/profiles/PowerKCM.cpp#L228

10 years ago there was an api for this but it was removed https://invent.kde.org/plasma/powerdevil/-/commit/57244ee8df47d3343e7557f108825580b7c59f2f#d0694e2e943e9bc5a464298284074971804e7b75_85_83

On systems where there is no physical power button the setting will still show confusing users. Additionally, if such systems have a hardware sleep button, the user may be think that this setting allows for configuring the sleep button (which it does not).

Are you able to share what kind of hardware it is? If it doesn't have a power button, how do you turn it on when it's off?

Nintendo Switch. Custom kernel and rest of bootstack as necessary.

I only thing that matters is the button that is used to actually turn the system on from fully off is mapped as a "sleep" button for the best compatibility with most linux distros. The users expect the button to function as a sleep button by default but it would be nice still for the button to be map-able on KDE since it used to have the ability to do so.

I think the Steam Deck does something similar, though perhaps in reverse: it has a power button that puts the device to sleep when pressed once, and you have to long-press it to make it behave as a power button.
