Description: As new portable devices are sold that support the Windows operating system, it is helpful to know the type of power management supported by the device in order to to maximize battery life. This document will show a quick way to view what power options are available on a Windows 8 computer.

1. Open an elevated command prompt.
   
   • On a PC or notebook with a keyboard, from the Windows 8 Start Screen, type Command and then right click on Command and select Run as administrator.
     
   • On a touch-screen PC or tablet, from the Desktop screen, press and hold (for about two seconds) the Windows icon (lower left hand corner) until a box appears. Release the icon and a quick link menu will appear. Choose Command Prompt (Admin).
     
2. Select Yes to the user account control message.
3. At the prompt (flashing cursor), type powercfg /a and press Enter.
   
4. A list will appear with power options that are supported as well as power options that are not supported by that particular system.
