Shut down the computer. Disconnect all external devices connected to the computer. Disconnect the power from the computer by first unplugging the power cord from the AC outlet and then unplugging the AC adapter from the computer.
Close the screen and turn the computer over. Loosen the three Phillips 2.5×9.0 captive screws that secure the keyboard to the computer. They are secured by a spring clip at the back, so they will not be easily removed. All that is required is to loosen those.
Turn the computer display-side up, with the front toward you. Open the computer as far as possible. There are four retention tabs that hold the keyboard down.
