So I just got a brand new macbook pro non-retina for school, because my family didn't want me to wait. I got it just a few hours back, and it has been great except, that if I am using the computer while it is charging the charger gets really warm and the left side near the charger gets a bit warm. However, if the MacBook is off and plugged in there is no heat at all. Is this normal or is this something to do with the computer or charger? Thanks for any help.
