Introduction

Go to step 1

This guide is for the Lenovo Legion Y520-15IKBN Touchpad Button Board replacement. The Touchpad button board allows the mouse pointer to travel around the screen via touch. It may need to be replaced if your laptop cursor no longer detects movement from your finger or the right and left click button does not fully press down.

Before you begin this repair, turn off your laptop and unplug it from the charging adapter. It is also a idea to remove or disconnect the battery from the motherboard to reduce the chance of damage to your device. Additionally, take anti-static precautions such as using an anti-static wristband and mat to prevent damage to electronic component

Step 6 Touchpad Button Board

Use a spudger or a clean fingernail to flip up the locking flap on the two ZIF connectors securing the touchpad button board to the motherboard and touchpad.
Once the flaps are in the unlocked position, use tweezers or your fingers to gently pull the cables out of their sockets using the blue pull tabs.
To reconnect, make sure the locking flap is flipped up and gently reinsert the cable. Then, flip the locking flap down to secure the cable. The cable should slide into the socket with little to no force. If you're having trouble, remove it, check that the flap is fully unlocked, and try again.
