Insert one arm of your tweezers under the corner of the touchpad shield.

Make sure to insert your tweezers between the shield and the frame. Don't pry behind the metal frame.

Gently pry up to release the clips securing the shield.

Try not to deform the shield too much. You'll need to reinstall it during reassembly.

Repeat this process around the perimeter of the shield until you can remove it.

To reinstall the shield, orient it correctly and press down around the perimeter to engage the shield clips.
