Description Neal Gompa 2025-03-04 15:07:31 UTC 
SUMMARY
Starting in May of this year, a new EU directive is coming into force about power management that requires computers that offer the ability to disable power management functions to warn users of the consequence of increased energy consumption when doing so.

The exact wording in question is under Section 2, Functional requirements:
> (5) The equipment may offer the user the option to deactivate the 
> power management function. In such cases the users shall be warned
> about the increased energy consumption of that action.
> That warning shall be included in the instruction manuals and,
> where applicable, be made available on the displays integrated in or 
> connected to the equipment, excluding information or status displays.
> That option shall not be part of the installation procedure of the 
> equipment and shall require a separate user action on the equipment.

We do not yet have this in our UI and we need this to be implemented fairly soon because not having it will prevent KDE Plasma from shipping on devices in Europe once this goes into effect.

So we need some kind of in-place warning to users that turning off default power management features will result in increased energy consumption.

SOFTWARE/OS VERSIONS

applets/batterymonitor: Warn about higher energy consumption when blocking sleep

EU Regulation 2023/826 requires connected devices to auto-suspend
after at most 20 minutes. The user may disable this but a warning
has to be presented when they do.

kcm: Show warning when disabling autosuspend or setting it too long

EU Regulation 2023/826 requires connected devices to auto-suspend
after at most 20 minutes. The user may disable this but a warning
has to be presented when they do.

The warning is only shown when changing the setting, not when it
has already been changed before.

It's not required for desktops.
