By default, Windows based platforms enable device and system power management technologies to help improve energy efficiency and reduce power consumption. Two of the most effective power management features are display power management and automatic sleep. However, in some scenarios, applications or drivers must temporarily disable these power management technologies to perform tasks as the user expects. A good example is video playback. If the computer plays a DVD for several hours, the user does not interact with the system via keyboard or mouse. The display and sleep idle timeouts must be temporarily disabled so that the DVD movie can play without interruption.
By using power availability requests, applications, services, and drivers can temporarily disable power management features to accomplish user scenarios. Availability requests can prevent the display from turning off after inactivity, and prevent the computer from automatically sleeping, enable Away Mode, and shutting down.
