Peel up the six cable loops securing the antenna cables to the upper case.

Gently pull the cable loops slightly out of the channel cut into the upper case one at a time.

Use your spudger to open up the plastic loops as you de-route the antenna cables through them.

Repeat this for all five retaining loops.

Remove the outer 4.9 mm T8 Torx screw securing each display hinge to the upper case (two screws total).

Open the display until it is perpendicular to the upper case and place it on a table as shown.

While holding the Air steady, remove the remaining 4.9 mm T8 Torx screw from the lower display bracket.

Before removing the last display screw, be sure to hold the display and upper case steady with your other hand. Failure to do so may allow the components to fall onto the table, causing potentially expensive damage.

Remove the last 4.9 mm T8 Torx screw securing the display to the upper case.

Push the upper case slightly toward the display assembly, then rotate it away from the front of the display assembly.

Once the two display hinges have cleared the upper case, remove the display and set it aside.

Keep track of the shims under each of the two display brackets. When installing the display, be sure a shim is installed under each display bracket (against the upper case) as shown in the third picture.
