I am working on an where i need to get a notification when power supply interrupted. several code which use Win32_Battry and Win32_PowerSupplySatus dll File for show Power supply status. but it works only for Laptop computer. Because they have battery. But In Desktop Computer there is no any battery. So i don't get any response for Desktop. Over all i want the code in C# for get a Notification when Main Power supply off and desktop system works on UPS. Kindly help me..

High = 1,
Low = 2,
Critical = 4,
Charging = 9,
NoSystemBattery = 128,
Unknown = 255
}
[StructLayout(LayoutKind.Sequential)]
public class SystemPowerStatus
{
public ACLineStatus ACLineStatus;
public BatteryFlag BatteryFlag;
public Byte BatteryLifePercent;

GetSystemPowerStatus(sps);
return sps;
}
