Yeah definitely you should convert it off always. It not supposes to be always switched on or something. It s just an electric powered devices that actually provides an urgent situation energy to the program without any disruption when the major energy is converted off. So better cost it up and also create sure that you move it off whenever you are not operating on your program. Actually I would say that you should move it off always when not in use and not just for once in 2 to 3 times.
