Remove the four 5 mm screws from the back panel of the laptop using a Phillips #1 screwdriver.

Slide a small plastic card between the crevice of the back panel of the laptop and the laptop itself.

Turn the card clockwise until you have a wide gap between the back panel and the laptop. Repeat this step all around the laptop to remove the back panel.

DO NOT insert the card too deep into the laptop, or you may damage or break the components inside the computer. Like the picture, you only need to insert a small corner of the card into the laptop.
