Open the laptop so the display screen is bent fully back with the display facing upward, parallel to the surface you are working on.
Wedge the Phillips 00 screwdriver above the F1 key, and separate the top piece of plastic from the body of the laptop. Don't worry about breaking it! You will need to forcefully wedge the screwdriver under the plastic, simultaneously pushing upward and forward.
Once that section has popped up, work on pulling the rest of the plastic piece up and out, alternating from left to right.
