Samsung note 4 not working

Welcome to my add for a Samsung galaxy Note 4, selling for a friend, phone has been left sitting and now it will not switch on. Not sure what is wrong, comes with box, fast charger and spen, the back cover slightly broken please see pictures. Easy fix for anyone who knows how to.
