-
Save your work, fully shut down your laptop, and unplug all cables.

Use a Phillips screwdriver to fully loosen (not remove) the five captive screws securing the bottom cover.
-

-
Position your laptop so the rear edge (with the screen hinge) is closest to you.
-
Insert the flat end of a spudger between the rear edge of the bottom cover and the frame, near the middle screw and ELITEBOOK text.

Use your spudger to pry up the cover to release the clip securing it.
-
Leave the spudger inserted under the bottom cover for the next step.

Slide the cover towards the screen hinge to disengage the clips on the opposite edge.

Slide an arm of a pair of angled tweezers under the metal neck of one of the coaxial connectors on the WLAN (Wi-Fi) module, near the right hinge.

Repeat the process to disconnect the remaining coaxial connector.

Use tweezers to hold a connector in place over its socket and gently press down with your finger or a spudger—the connector should "snap" into place. If you're having trouble, reposition the head and try again. Don't use excessive force.
