If your touchpad is experiencing the cursor drifting, unresponsive input, erratic input, or any input that is continuously not intended by the user, it may need replaced. First, check the user manual for any troubleshooting steps. If that does not help, a new touchpad may be advisable.

Open the laptop so the display screen is bent fully back with the display facing upward, parallel to the surface you are working on.

Once that section has popped up, work on pulling the rest of the plastic piece up and out, alternating from left to right.

Now you need to detach the screen from the rest of the laptop. Start by removing the screws on the hinge (indicated in picture one).
After removing the screws look to the right side of the laptop. Remove the white wire in the channel found there. To do this you only need to move the wire around the plastic pieces holding it down.
You will also find a connector on the left side of the laptop (indicated in picture two in the square). Pull gently on it to detach it. You may now pull the display completely off.
