    Introduction


    Away Mode is a power management usage model for media PCs that lets the computer appear turned off to the user while the system continues to perform tasks that do not require user input, such as recording television and viewing Media Center Extender sessions.

    This paper describes how Away Mode interacts with power policy in Windows, and provides guidelines and implementation details for software developers who want to take advantage of Away Mode support in their media applications.
