Installing the Keyboard

NOTICE: The keycaps on the keyboard are fragile, easily dislodged, and time- consuming to replace. Be careful when handling and installing the keyboard.

1. Place the keyboard on the palm rest at the front of the computer with the keys face down and the keyboard flex-cable connector toward the back of the computer.
   
   

NOTICE: To avoid damage to the connector pins, press the keyboard flex- cable connector evenly into the keyboard flex-cable connector on the system board, and do not reverse the keyboard flex cable.

2. Insert the keyboard flex cable into the keyboard flex-cable connector on the system board until the cable is completely inside the connector.
   
   
3. Press down on the two corners of the keyboard flex-cable connector until the keyboard flex cable is secure.
   
   

NOTICE: Position the keyboard flex cable so that it is not pinched when you replace the keyboard in the bottom case.

4. Rotate the keyboard forward and fit it into the bottom case, ensuring that the tabs at the bottom of the keyboard fit into place.
   
   

When the keyboard appears to be completely seated, ensure that the front edge of the keyboard is aligned with the edge of the palm rest before proceeding. The keys should be flush with the left and right surfaces of the palm rest.

5. Replace the three M2 x 4-mm screws at the top of the keyboard.
   
   
6. Connect the power button cable to the power button board located on the back of the hinge cover.
