Powercfg Command-Line Options

  • 아티클

Applies To: Windows 8, Windows 8.1, Windows Server 2012, Windows Server 2012 R2

You can use the powercfg.exe tool to control power schemes (also named power plans) to use the available sleep states, to control the power states of individual devices, and to analyze the system for common energy-efficiency and battery-life problems.

powercfg /COMMAND [ARGUMENTS] [/?]

Parameters

The following command-line options are available for powercfg.
