Many systems that run Windows are used primarily for entertainment and media scenarios. Away Mode is a technology that allows the system to appear and sound turned off while it remains on and available to share media to other devices. Away Mode is not a new system power state or a replacement for correct support of Sleep or WoL.
Away Mode can be configured in Windows power policy and may be enabled by applications by using the Power management functions. Windows takes advantage of Away Mode when it is used with Windows Media Center Extender devices or with Windows Media Sharing.
System manufacturers should use the information in this paper to:
Understand the operation of Away Mode and its configuration in Windows power policy.

Register for Away Mode notifications and pause playback of media when the system enters Away Mode, and resume media playback when the system exits Away Mode.
