Lenovo Ideapad Flex 15 Wireless Networking Card Replacement

Start by removing the feet near the LCD hinge of the laptop to reveal two screws.

Using a Phillips #1 screwdriver, remove the top five (30 mm) screws underneath the battery.

Once both feet are removed, two (40 mm) screws will reveal themselves. Unscrew these.

Working your way around the outer edges of the Flex 15, remove the 8 (30 mm) outer screws.

Remove the one (40 mm) screw in the middle of the Flex 15.

Using a plastic opening tool, make your way around the edge of the laptop.

There is a visible line between the bottom shell of the laptop and the laptop body itself.

Make sure to pry evenly around this edge and only remove the bottom of the laptop when it is fully loose.

Locate the wireless card. It is located above the black ribbon cable, underneath the battery terminals.

The wireless card has two antennas (black and white cables) that are attached to other parts of the laptop.

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.
