Is it possible to change this via command line

dacrone · 2025-03-03T21:10:15-0500

command prompt as admin:

Code:

powercfg /setactive DED574B5-45A0-4F42-8737-46345C09C238  #Best Performance

Code:

powercfg /setactive 381B4222-F694-41F0-9685-FF5BB260DF2E  #Balanced

Code:

powercfg /setactive 961CC777-2547-4F9D-8174-7D86181b8A7A #Better Battery Life

Battery Saver - Change the "0" to any number greater than Zero to enable Battery Saver at the Percentage dictated by the number you set:

Code:

powercfg /setdcvalueindex scheme_current sub_energysaver esbattthreshold 0

@dacrone, two of those quoted power plan GUID's are custom to your PC.

If you prefer to use the built-in aliases:

Code:

powercfg /setactive SCHEME_BALANCED
powercfg /setactive SCHEME_MIN
powercfg /setactive SCHEME_MAX

High performance mode is SCHEME_MIN (or minimize power savings).
Low performance mode is SCHEME_MAX (or maximize power savings).

It's counter-intuitive.

To use a custom power plan (like one that shipped with your PC, like HP does), you can list the available GUID's.

Code:

C:\Windows\System32>powercfg /list

Existing Power Schemes (* Active)
