7. Peel the tape that secures the display cable to the system board.
8. Using the pull tab, disconnect the display cable from the connector on the system board.
9. Disconnect IR camera cable from the connector on the system board (for models shipped with an IR camera).
10. Disconnect the touchscreen cable from the connector on the system board (for models shipped with a touchscreen).
11. Open the latch and disconnect the USH board cable from the connector on the system board.
12. Open the latch and disconnect the touchpad cable from the connector on the system board.
13. Open the latch and disconnect the LED cable from the connector on the system board.
14. Disconnect the coin-cell battery cable from the connecter on the system board.

NOTE:

 When you disconnect the coin-cell battery cable from the connecter on the system board, the CMOS setting is

cleared.

15. Remove the three (M2x3) screws that secure the system board to the palm-rest assembly and keyboard assembly.
