Is there an API that is executed before the computer goes into
standby mode (Start button/Shutdown.../Standby)?  Or possibly some
other way to detect that the computer is about to go into this mode?

  Thanks.

Check if you receive a WM_POWERBROADCAST message in the
Application.OnMessage event.

  Yes, that worked - Thanks!

An example:

type
  TForm1 = class(TForm)
    procedure AppOnMessage(var Msg: TMsg; var Handled:Boolean);
...

procedure TForm1.AppOnMessage(var Msg: TMsg; var Handled:Boolean);
begin
   case Msg.Message of WM_POWERBROADCAST:
        begin
        Form1.Label1.Caption := 'WM_POWERBROADCAST'; //show it works
        end;
   end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
   Application.OnMessage := AppOnMessage;
end;

end.
