Introduction

This guide is on how to replace the touch pad on a HP ProBook 450 G4. The touch pad is the rectangle under the keyboard that acts as a mouse, or a control to the cursor on your screen. You may need to replace your touchpad for a few reasons, such as your touch pad being unresponsive, it being damaged or dented, or your touchpad is picking up movements that you aren't controlling.

Tools

Step 1

Power your laptop off.
Flip the laptop over.
Orient the laptop so the two vents on the bottom face upward and are further away from you.

Step 2

Use the Phillips #0 screwdriver to remove the 6.8 mm screw that secures the vent panel to the laptop.
Use the spudger to separate the vent panel from the laptop.
Slide the vent panel off the backside of the laptop.

Step 3

Use the Phillips #0 screwdriver to remove the black 3.2mm screw that secures the hard drive to the left side of the laptop.

Step 4

Use the spudger to lift the left side of the hard drive up.
Pull the hard drive diagonally to the left to release the hard drive from the laptop.

Step 5

Remove the 6.6mm T8 Torx screw located below where the hard drive used to be.
Remove the 6.6mm T8 Torx screw located below and to the left of the circular, silver and black fan.

Step 6

Use the spudger to press down on the two black tabs that are underneath where the hard drive used to be.
Apply pressure to the black tabs until they release and pop out.

My tabs(ProBook G4 455) did not release. The keyboard wasn’t attached to them at all. I ended up breaking one tab before simply popping out the keyboard from the other side(followed a YouTube video to figure out this step).

Step 7

Orient the laptop so the keyboard is facing upwards and towards you.
Insert the spudger in between the edge of the keyboard and the computer frame.
Slide the spudger around the edge of the keyboard until the keyboard is loose.
Gently pull the keyboard away from the body of the laptop.
Do not pull the keyboard all the way off because there is still a connector cable underneath that needs to be disconnected.

Step 8

Use a spudger to gently lift up the black locking bar on the keyboard connector.
Slide the keyboard ribbon out of the connector.
Remove the keyboard.
To re-attach the keyboard ribbon, slide it into the connector and swing the locking bar down.

Step 9

Flip the laptop back over so it is facing upwards.
Remove the six 6.6 mm screws underneath where the keyboard used to be using a T8 Torx screwdriver.

Step 10

Use the spudger to disconnect the nine cable connectors that secure the top case of the laptop to the body of the laptop.
Be extra careful while disconnecting the cable connectors because they can tear easily.

Step 11

Insert the spudger in between the top case of the laptop and its outer frame.
Slide the spudger around the edge of the laptop until the case comes off.
Remove the top case.

Step 12

Flip the top cover over.
Use the spudger to disconnect the cable connector labeled TP.
Be extra careful while disconnecting the cable connector because it can tear easily.
