I just bought a Macbook Pro not even a month ago and its my first Mac. Since school has officially started i had a couple questions regarding my MBP. Basically i'm wondering if its harmful to carry my MBP while its in sleep mode. I carry it in my backpack (which has a sleeve for laptops) and i was to make sure i'm not damaging the HDD or any other hardware since its being shifted around while technically powered on. I figured apple would have taken this all into consideration since Macbooks are so popular among students. But can anyone give me any input on this. I really dont want to damage my $1600+ investment. thanks
