Find a flat head or Phillips head screwdriver.

Simultaneously push the clips outward while lifting the rear casing and keyguard away from the front casing.

Remove the key guard from the rear casing by taking it out of its position.

Locate and unplug the black component of the antenna from the motherboard.

Under the black component should be a blue component. Unscrew this component in order to free the antenna.

Slide the antenna out of the green tubing and slide the green tubing out of it's corresponding hole on the motherboard.

Lift the motherboard out of its location in the front casing.

Do this slowly and gently so that none of the motherboard's components are damaged.
