My advice: listen to them.
I am still an undergraduate student, and I lived in the dorms on campus for two years. You simply are -NOT- going to get any musical good out of that laptop. I have a separate laptop that I do all my college/school things for my Comp Sci degree and my Music Composition degree that have nothing to do with the software I use for music production outside that realm.
Here's a picture of my dorm room with my "gear" in it from 2009.
I simply took the dorm supplied desk, built the little "bridge" for my monitors and monitor (heh), and it worked very, VERY nicely. I mostly used the headphones really, for obvious reasons, and I'd also like to add that I shared this room with another person.
I also err on the side of being more social and outgoing as far as school events are concerned - I attend football games, all that fun stuff, go out on the weekends. Doesn't keep me from knowing when to focus and get work done, which is an important balance you'll have to have. As far as needing your laptop for convenience, you'll find that online applications are making this super easy - but beyond that most software that you'll likely use for school was developed for really the crummiest of computers to operate on. If it's something high end like in the digital design field or something truly intensive, your school should have labs for you to work at - which, even with a desktop and laptop, I still use quite often.
Just sayin', it can be done. (:
EDIT:
Also, EWQL Play will expel ROT all over your harddrive for how much use you'll give it, rendering a laptop's lifespan mooooterific.
