Testing the code bellow in a non-surface device works just fine but when I try in a surface, I only get notifications when I remove the power cable ('statusChange' powerMode is triggered). Putting the surface in SLEEP the handler it's not called ('resume' and 'suspend' powerModes are not being trigged).
Anyone knows why ? Thank you.

}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
SystemEvents.PowerModeChanged += new PowerModeChangedEventHandler(SystemEvents_PowerModeChanged);
}
private void SystemEvents_PowerModeChanged(object sender, PowerModeChangedEventArgs e)
{
listView1.Items.Add(string.Format("{0} : Power mode changed = {1}", DateTime.Now, e.Mode));
}
}
