The following procedure allows the changing of the rear display bezel without removing the display assembly from the computer. Do not attempt to rotate the display back farther than the hinges allow or your computer may be damaged.
Open the computer with the display facing you and rotate the display back as far as possible.
Remove the T6 Torx screw from the bottom left corner of the display assembly. The computer casing will not allow the screwdriver to be inserted directly into the screw, so be careful not to strip the screw.

Step 4

The next few steps require the use of plastic opening tools and spudgers that will probably be destroyed in the process. Have a few spares of each tool handy.
Insert a plastic opening tool between the left edge of the front display bezel and the plastic strip attached to the rear bezel, with the edge of the tool angled toward the LCD.
Rotate the tool away from the LCD to pop the rear bezel off the tabs on the front display bezel.
Work along the left edge of the display until the rear bezel is evenly separated from the front bezel.
Freeing these tabs may require some force. Be sure to support the display assembly with your other hand to avoid putting too much strain on the hinges.
