Remove the power button board:
1. Position the top cover upside-down.
2. Disconnect the cable from the board (1).
3. Remove the Phillips PM2.0×3.0 screw (2) that secures the power button board to the top cover.
4. Lift the top side of the board up at an angle, and then lift board out from under the tab to remove
it from the top cover (3).
Reverse this procedure to install the power button board.
When installing the power button board, insert the bottom of the board into the slot, and then rotate
board down into place. If the cable is connected to the board, it blocks the view of the tab on the
board and the slot it inserts into.
