Assembly: System (in system.dll)
A PowerModeChanged event is raised when the user suspends or resumes the operating system, or when a system power status notification occurs. A system power status notification can occur when a weak or charging power source is detected, or when a transition from AC or battery power source occurs.
The Mode property of a PowerModeChangedEventArgs indicates the type of power mode event that has occurred.
