Basics of Power Management

[Michells]

Hello All,

I am investigating on how Windows shutdowns the PC.

I mean: When the shutdown(HardKey) is pressed once,all my applicaiton
closes and system shutdowns.

My Question:

1) When I press Shutdown(Hardkey) once. which API is being used by the
OS
2) If yes (i.e OS uses some Power management API) How will this API is
being called and who calls it, when I press Shutdown button.(Hardkey).


Note:Hardkey refers the button that every PC have on the CPU (i.e
Shutdown and Reset buttons)

Regards
Michells

Control Panel has a Power Management app. It can set which call to the
"Windows Management Interface" (WMI) is called when you press that button.
