Power Manager provides several functions to allow applications to affect system and device power management. Of the functions in this list, only GetSystemPowerState, SetPowerRequirement, and ReleasePowerRequirement are intended for use by generic applications. For example, applications can use SetSystemPowerState to suspend the system, but Power Manager may restrict the system power states that can be entered as a result of application requests. The other functions are intended for use by OEM applications, such as Control Panel utilities. The following table shows the device power management functions.
