Pull the keyboard release tabs toward you and lift up on the keyboard until it pops free. Note that the keyboard ribbon is still attached to the logic board, so you cannot completely remove the keyboard yet.
If the keyboard does not come free, use a small flathead screwdriver to turn the keyboard locking screw 180 degrees in either direction and try again.
Rotate the keyboard away from the screen and rest it face-down on the trackpad area.
If your computer does not have an airport card, you can skip the next two steps.
Grasp the clear plastic tab on the airport card and pull up and toward the display.
Hold the airport card in one hand and use your other hand to remove the antenna cable.
You have successfully removed the Airport Card. To reassemble your laptop, simply follow the directions in reverse order.
