    Subclass the window with MemoryEx and catch the WM_POWERBROADCAST notification :yes

        Code:
                      ---On Show
                      WM_POWERBROADCAST = 0x218;
                      WM_DESTROY = 0x0002;
                      PBT_APMPOWERSTATUSCHANGE = 10;
                      PBT_APMRESUMEAUTOMATIC = 18;
                      PBT_APMRESUMESUSPEND = 7;
                      PBT_APMSUSPEND = 4;
                      PBT_POWERSETTINGCHANGE = 32787;
                      local s = Subclass.Create(Application.GetWndHandle(), function(hWnd, uMsg, wParam, lParam)
                        if(uMsg == WM_DESTROY)then
                         Subclass.Remove(Application.GetWndHandle());
                         return 0
                        end
                        if(uMsg == WM_POWERBROADCAST)then
                         if (wParam == PBT_APMPOWERSTATUSCHANGE) then
                         
                         elseif (wParam == PBT_APMRESUMEAUTOMATIC) then
                         
                         elseif (wParam == PBT_APMRESUMESUSPEND) then
                         
                         elseif (wParam == PBT_APMSUSPEND) then
                         
                         elseif (wParam == PBT_POWERSETTINGCHANGE) then
                         
                         end
                        end
                      return Subclass.OldWinProc(hWnd, uMsg, wParam, lParam);
                      end)
        something like that, it just mirrors whats linked to, grab MemoryEx here:

                        Create a hidden generic window and hook that to receive desired event

                        or hook desktop window to do that ,but be careful with that because any exception might cause your app to crash or explorer.exe who owns the desktop window

                        you should implement my first advise , this is the way to do it

                        DLLs,Console apps, Shell extensions etc. using that way to catch broadcast messages
