Using two fingers, pinch the power supply wire and gently lift it upward. Move it away from the metal plate.

Next, unscrew the four 3.3mm T8 Torx screws and remove the metal plate.

The metal plate fits snugly into the gap. To reassemble the device, push the rounded edge of the plate into the gap first. This will wedge the gap open so that you can fit the rest of the plate into its proper place.
