Remove the two screws from the top of the screen and four screws in bottom corners.
These screws hold the metal frame to the plastic back cover of your screen. It is a good idea to hold the screen and the back cover together as your remove the last screw. Once they are removed you can move the screen forward and away from the backing to make the other screws easier to reach.
Next disconnect the camera cable that plugs in to the webcam above the screen. This will allow screen to be moved further away from the back cover
