Playing Halo MCC on Series X. Using Corsair mouse/keyboard. 1. System won’t allow me to shut off controller manually to save battery. (I can navigate with mouse and keyboard just fine). When I shut it off I get a message that I need to reconnect the controller to continue. I’ve tried changing several settings, including the preferred input setting. 2. When I leave controller on to allow the game to play, it times out…and then I get the same message as above. 3. I do the following to try to solve it: If I start the console with its own button (not the controller), I can open the game but cannot press [Enter] to start when prompted, so I can’t play. How do I simply play mouse/keyboard enabled games without having to have the controller on? I’m not even trying to play multiplayer. Just working through all of the campaigns. Thanks!
