Insert the plastic opening tool into the seam on the top of the screen.

The seam is where the back screen cover and the plastic bezel around the edges of the screen meet.

Use the plastic opening tool to pop open the clasps that keep the casing on the screen.

It helps to use the plastic opening tool like a crowbar.

Follow this seam around the laptop's screen with the plastic opening tool until the plastic cover comes off.

Don't be afraid to use your fingers to help pop open the clips.
