I have a 17 inch early 2011 MacBook Pro. I just took it in to get the hd replaced . I got home and took it out of the sleeve and a screw fell out of the bottom. I placed it back in the hole and it fell all the way in and when turned back the right way up it falls out . I.e the screw threads have been stripped . I am going to call them but I'm not sure what to ask for . I think to fix the threads means a complete change of body which seems a bit extreme and inconvenient . However I would like some sort of compensation . Any recommendations of how to procede ?
