I’m not sure if i get you right, but… HDMI is kind of an one way street. You can’t send any signal / data from your TV to the laptop that way. So you can’t control your laptop through the TV remote. If you hook up your TV through HDMI it becomes a stupid monitor. My best advice would be to get a small wireless keyboard/touchpad combo to connect to the laptop. Maybe a remote control you connect to the laptop will also do.
