determine the time when the windows system is waked up from the sleep

Question

Can any one tell how to determine the time at which the windows pc is waked up from sleep? using C#.

I know how to get the time when the computer is powered on.

You could [inspect the System event log](https://msdn.microsoft.com/en-us/library/k6b9a7h8%28v=vs.90%29.aspx). My Windows 7 PC logs an event from source Power-Troubleshooter when the system resumes from suspend mode. — Axel Kemper, Apr 07 '16 at 16:14

You can visit this site to detect when the pc wakes up or sleeps Also you can use the Stopwatch class to get the time.

private void SystemEvents_PowerModeChanged(object sender, PowerModeChangedEventArgs e)
    {
        switch (e.Mode)
        {
            // Cuando regresa del sleep 
            case PowerModes.Resume:
                sleepStopwatch.Stop();
                break;
            // Cuando se va en sleep
            case PowerModes.Suspend:
                sleepStopwatch.Start(); 
                break;
        }
    }
