will this backpack hold my 17 inch computer along with 15lbs worth of books?
It does not have a laptop specific pocket but yes it will hold that size of laptop. Also it will hold your books no problem as well.
I would make sure to get some sort of sleeve for your laptop- you'll kill the thing by letting it rattle around with 15 lbs of books. Besides, for a 20 lb load (laptop + books) I'd be looking for something that allows you to carry the weight without deforming your spine. Osprey and Deuter both make some nice daypacks and commuter packs that would do the job better than this pack.
