Introduction

This is a step-by-step guide on how to remove and replace a wireless card in your HP Pavilion 14-b120dx laptop. Whether you are experiencing hardware failure, difficulty connecting to the internet, or just need to upgrade to a better card, this simple guide will help you quickly and safely replace and install a new Wi-Fi card to your device.

Before you begin this project, we recommend that you find a clean, dry, and flat surface to work on. Power off your laptop completely and unplug it from the charging adaptor and any peripherals.

What you need

Insert the plastic opening tool between the keyboard and the palm rest.
Pry upwards until the keyboard section detaches from the laptop.
Repeat this around the edge of the entire keyboard.
Sections will make loud snapping noises as they detach from the palm rest - this is normal.

Step 4

Lift the keyboard slowly up until the connecting cable is exposed.
Carefully lift the flap on the ZIF connector using a fingernail or plastic opening tool. This will release the cable.
Detach the cable.

Insert the plastic opening tool into the seam between the palm rest and the laptop.
Pry upwards until the palm rest separates from the laptop.
Repeat this process around the entire computer.
These steps will be similar to the ones you took to remove the keyboard. Again, you will hear snapping noises.
