hello everyone I'm wanting to hook up my macbook to an external lcd and have it in closed mode so its (almost) like a desktop with a normal*keyboard and mouse. My question is if I leave it closed all the time and just put it to sleep when I'm not using it (so I dont have to open it to awitch it on again) will this cause any harm? Also if it gets too hot inside will it take care of that itself (turn itself off?) or just become dangerously hot. I do some video encoding. I love my macbook so want to cause it as least harm as possible thanks for any replies.
