I just bought a new mbp and I wonder how to use it in order to preserve battery from bad use. I had pc laptops in the past and I all I did is to have them connected to the socket all the time. No special care about their batteries. Disconnection happened only when I had to travel. Is this safe to do it with macbook pro too? What do I have to know and what do I have to do in order to have my battery in good condition for years to come?
