This is the laptop the editor of this site uses today when on a Windows machine. I first had one of these while an employee at HP, it is thin, light weight and a breeze to carry around. Still has the power you need and ample expansion. I added an SSD card to mine adding more fast capacity.
The keyword also lights up which is a small perk but I have found it useful when typing in the dark, I imagine in a dorm shared with a sleeping roommate you might as well.
