CPU power plan for AC mode

The CPU power plan (CPU Governor) used in AC mode
Possible options:

  • High performance: Full performance with maximum processor speed. (Default)
  • Balanced: Slower regulation of performance in a balanced manner according to the demands of programs.
  • Power saver: Lowest processor speed

You can also use the battery tray app to set the CPU power plan for the current mode in use (AC or battery). For details, see Battery.


Lid close action while plugged in

The action that is performed when the lid of the device gets closed. 

Possible options:

  • Suspend: When the lid gets closed, the device goes into suspend mode and applications are closed. When the lid is opened again, the device starts, connections are restarted, and re-login is required. Applications have to be started manually. (Default)

    The suspend action is only performed if there are no external displays connected and activated. When an external display is connected and activated, the internal display is turned off, and if the internal display was the primary display, a new primary display is assigned.

  • Turn off display: When the lid gets closed, the internal display is turned off.
