Hi everyone, I have a dilemma and I was hoping the MacRumors community would have some answers. I have the 2011 MacBook Pro 15-inch (low end model) and I take it to school every day. I usually shut it down in between classes, but is shutting it down and restarting it around 3 or 4 times a day good for it? Should I just put it to sleep in between? I just put it to sleep between classes today, and it didn't really affect the battery life.. I have heard constantly shutting it down can reduce the life of the internal parts. Is this true? What should I do? Thank you!
