    • To remove these cables, take your plastic opening tool and gently pry around the metal base above the PCB until the connectors are freed.

    • Repeat this step with both the black and the white antennas

    • There are two (30 mm) screws attached to the wireless card underneath the antenna. Remove both of these with your screwdriver (bit PH1).

    • Once the screws are removed, the wireless card will tilt upwards. Firmly grab the card with one hand and pull it slowly, diagonally, out of the socket.

    • To replace this card with a new wireless card, put the contacts back into the socket. The wireless card should be sitting at a 45 degree angle.

    • To seat the wireless card, put the two screws back into the card. It should be flush against the base of the laptop.

    • Line up the white antenna back in the original (left) terminal. Push the antenna gently onto the wireless adapter with one finger. Give it a small tug to ensure it is connected firmly.

    • Do the same with the black antenna, snapping it onto the right antenna port.
