I'm trying to download that program that allows you to close the lid of the laptop for the MBP and keep the Internet active. I'm not going to do it much, just sometimes when I'm in class I'd like to be able to do it. Is that OK for the MBP? thanks! also, will it still go to sleep at night? I usually play music when I go to sleep, but the laptop's screen cuts off after a while, i'd still like it to do that.
