Turn the computer so that the ports are facing you.
If the keyboard is locked, open the port cover and turn the keyboard locking screw until the keyboard is unlocked.

Pull the keyboard release tabs toward you and lift up on the keyboard until it pops free.
Make sure you have removed the laptop battery and CD/DVD module from the expansion bays before proceeding.

Lift the keyboard out by pulling it up and away from you. Rest the keyboard, face down, on top of the trackpad.
In order to replace the keyboard, you must first remove the modem.

Remove the three silver Phillips screws that attach the heat shield to the internal metal framework.

The keyboard can be laid back over the trackpad.

Use a spudger, the tips of your fingers, or a flat non-metal tool to get under the modem's edge and pry it up from its socket as shown in the picture.
