have you tried  ExitWindowsEx(EWX_POWEROFF ,0);  ?

from microsoft;
******************************
uFlags
     One or more of the following flags specifying how to shut down or reboot the computer:
     EWX_FORCE = 4
          Force any applications to quit instead of prompting the user to close them.
     EWX_LOGOFF = 0
          Log off the network.
     EWX_POWEROFF = 8
          Shut down the system and, if possible, turn the computer off.
     EWX_REBOOT = 2
          Perform a full reboot of the system.
     EWX_SHUTDOWN = 1
          Shut down the system.
dwReserved
     Reserved for future versions of Windows. Always set to 0.

Try this

function ExitWindows(RebootParam: Longword): Boolean;
var
TTokenHd: THandle;
TTokenPvg: TTokenPrivileges;
cbtpPrevious: DWORD;
rTTokenPvg: TTokenPrivileges;
pcbtpPreviousRequired: DWORD;
tpResult: Boolean;
const
SE_SHUTDOWN_NAME = 'SeShutdownPrivilege';
begin
if Win32Platform = VER_PLATFORM_WIN32_NT then
begin
  tpResult := OpenProcessToken(GetCurrentProcess(),
    TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY,
    TTokenHd);
  if tpResult then
  begin
    tpResult := LookupPrivilegeValue(nil,
                                     SE_SHUTDOWN_NAME,
                                     TTokenPvg.Privileges[0].Luid);
    TTokenPvg.PrivilegeCount := 1;
    TTokenPvg.Privileges[0].Attributes := SE_PRIVILEGE_ENABLED;
    cbtpPrevious := SizeOf(rTTokenPvg);
    pcbtpPreviousRequired := 0;
    if tpResult then
      Windows.AdjustTokenPrivileges(TTokenHd,
                                    False,
                                    TTokenPvg,
                                    cbtpPrevious,
                                    rTTokenPvg,
                                    pcbtpPreviousRequired);
  end;
end;
Result := ExitWindowsEx(RebootParam, 0);
end;


//And call it like this

procedure TForm1.Button1Click(Sender: TObject);
begin
ExitWindows(EWX_POWEROFF or EWX_SHUTDOWN);
end;
