The keyboard has a cable connected to the system board. Before lifting the keyboard completely off the laptop, disconnect the ribbon cable. We show this process in the next step.
Place the computer right-side up.
Place your hands over the keyboard, gently press down, and slide the keyboard towards yourself.
Gently pry the keyboard from the top.
Lift at an angle and only detach enough so you do not inadvertently detach the keyboard cable.
