While holding the front panel open at about a 90º angle, remove the following screws securing the front panel assembly cable bracket:

Three 1.3 mm Phillips #00 screws

One 3.0 mm Phillips #00 screw

Don't lose track of this screw! It's very important that the one 3.0 mm screw goes in the top-right corner of the plate. Anywhere else may cause damage to the logic board.
