Original value of a laptop does not come into play when you are trying to resell it. Most, even newer ones, get abused and/or tortured by their owners... battery life shortened, scratches on the chassis, that sort of thing.
That being said, if it's well taken care of and purchased within the past 6 months then yes, you can probably ask that much on Craigslist. I've flipped laptops more than 6 months old for closer to their original price but those are usually powerhouses (with discrete graphics for gaming) and I live in a college town so there's a market for what I am trying to sell. It also doesn't hurt that I work in IT and meticulously care for my devices and I make sure I point both of those out to my buyers.
