We have this rule at my university. I really like it :)

what university? I wanna drop my penn state scholarship and go there.

Taylor University in Upland, Indiana. :) It's a really safe school because it's small and in the middle of nowhere lol. People routinely leave laptops and stuff unattended in public places and I've never heard of anything getting stolen. Like with the laundry thing, someone would probably plug your laptop in for you if they noticed the battery was low. :)

I actually just found a college, where they have all the comp sci majors in a room that is as secure as the white house's bunker, and they have super computer in it with over 100 processors.
