Unscrew and remove the two 2.5 mm black screws with a Phillips #0 screwdriver.

Put the screws somewhere they will not roll away so you do not lose them.

Notice that these 2.5 mm screws are black, while the other 2.5 mm screws in the laptop are gold.

There are two other screws on the wifi adapter/card; do not remove these. Only remove the two screws indicated in the picture.
