Event to detect System wake up from sleep in C#

Question

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:

SystemEve         


        

Answer 1

You need to inspect the Mode property of the PowerModeChangedEventArgs that is passed to the event.

From MSDN:

• Resume The operating system is about to resume from a suspended state.

• StatusChange A power mode status notification event has been raised by the operating system. This might indicate a weak or charging battery, a transition between AC power and battery, or another change in the status of the system power supply.

• Suspend The operating system is about to be suspended.
