Steps
1. Remove the four (T5, M1.4x4) Torx screws that secure the display FPC holder and display FPC to the system board.
2. Disconnect the display FPC from the system board and remove the interposer board.
CAUTION:
Technicians must remove the interposer board immediately after disconnecting the display FPC
to prevent the board from falling out of the system during subsequent removal procedures. The pins on the
interposer board are fragile. Avoid contact with the pins on the board. Instead, handle the board by lifting
and holding from the edges or the sides.
3. Loosen the single (M1.6x2.3) captive screw securing the WLAN bracket on the system board.
4. Disconnect the antenna cables from the WLAN module and unroute them from the metal clips on the system board.
5. Disconnect the battery LED FPC from the system board.
6. Disconnect the USH board FPC (for models shipped with a USH board) and touchpad FPC from their respective connectors.
