With the console on its top. Remove the four 12 mm Phillips #2 screws.

There may be a sticker covering one, or more, of the screws. Simply remove the it before the screws.

Flip the console on its feet and carefully lift the top casing from the back (where the AV/S and power ports are).

To avoid damage, do not completely remove the top case. There is a small circuit board--which houses two LEDs-- connected to the main circuit board.
