This module is a configuration tool for managing Power Management in KDE. It is a configurator for the PowerDevil daemon, that you can start or stop from the Service Manager module.
Through this module, you can define your computer's behavior in various situations, allowing you to save as much energy as possible.
Powerdevil works with Solid only and it's integrated in your desktop. You won't even notice it is running, apart from notifications. Moreover, Powerdevil checks your system capabilities first, so you'll see only options available for your system in this module.
Note that PowerDevil does not poll your system. This means that it will not waste energy while trying to save it, as some other power managers do.
This page has three tabs with predefined settings for On AC Power, On Battery and On Low Battery profiles.
There are a lot of options you can configure for each profile:
- Display Brightness

- Dim Display
If checked, the display will be progressively dimmed, until reaching brightness 0, in the amount of time you specify in the spin box.
