Broken hinge and plastic parts of screen

@xps15 download the service manual from here. You will need the back cover (available at places like this) and possibly new hinges.

Although both answers above are very good and proper.

You may want to try a quick fix and glue the hinge to the inside shell with JB weld. It's a cheap fix that may work for you, if it doesn't then go with the new parts: back shell and hinge.

Looks like you need replacement

·DISPLAY BEZEL

·DISPLAY PANEL BRACKET(S)

Most often sold as a pair (1 left /1 right).

However, I have seen brackets sold individually but usaully harder to find that way.

· TOP COVER

Most often sold w/o hinges

However, you might get lucky and find a cover w/ hinges.

·HINGES

Sold in pairs. (1 left/ 1 right)

I recommend replacing them as a pair. (These hinges are the reason for all the damage. Hinges get too tight (even seize up completely) putting stress on and causing the metal display brackets and plastic parts to brake).
