Solution

SystemEvents.PowerModeChanged += OnPowerChange;

private void OnPowerChange(object s, PowerModeChangedEventArgs e) 
{
    switch ( e.Mode ) 
    {
        case PowerModes.Resume: 
        break;
        case PowerModes.Suspend:
        break;
    }
}

Problem

I need to detect the system power state mode. To be precise, I need an event which fires up when windows 7 wakes up from sleep. I am already using: ``` SystemEvents.PowerModeChanged += SystemEvents_PowerModeChanged; ``` But the problem with this event is that it is raised up four times: possibly when computer goes into sleep mode and after computer wakes up. I want an event which is raised at computer wake up only. Is there any event for this?
