Laptop/Desktop Sleep Events

I was wondering if there was an event that is triggered when a laptop or desktop goes into sleep mode.

An example would be: When a user is working on his/her laptop and he/she flips the monitor down, the laptop goes into sleep mode.

Or when a user goes to Start → Shutdown → Sleep.

Are there any events built into .NET that determine this?

+2  A: 

Check this CodeProject article and these MSDN reference articles.

To find out C# DLLImport declarations visit pinvoke.net

I'm not necessarily looking for power management tools or change the power... i'm looking for when the computer sleeps or is on idle for a long time and the computer changes.

RegisterPowerSettingNotification function will help you. Then in WndProc method you should check Message value.
