Hi! I have a Dell Inspiron 7548, 15.6 inch full HD touchscreen, Please could you clarify me how to replace the screen I disassemble the laptop and took all the top part, I mean the hole "aluminum" outer part with the hole broken touchscreen, now it has both cables hanging, so I found a replacement on Amazon but it doesn't show the outer aluminum cover nor the connectors to the mother board.... Am I supposed to reuse those parts from the broken one? How did you do it ? Help me brother:)
