Replacing the Keyboard

1. Place the keyboard on the palm rest at the front of the computer with the keys
face down and the connector toward the back of the computer.
NOTICE: To avoid damage to the connector pins, press the keyboard connector
evenly into the interface connector on the system board, and do not reverse the
keyboard connector.
2. Connect the keyboard connector to the interface connector on the system board.
The keyboard connector may have a label showing the correct orientation of the
keyboard connector (relative to the display) in the system-board interface
connector.
3. Carefully turn the keyboard over. Align the keyboard boss supports, fit the left
side of the keyboard into place, and then snap the right side of the keyboard
into place.
NOTICE: Position the keyboard flex and track stick cables so that they are not
pinched when you replace the keyboard in the bottom case.
4. Check that the keyboard is correctly installed. The keys should be flush with the
left and right surfaces of the palm rest.
5. Replace the center control cover, close the display assembly, and then turn the
computer over.
6. Reinstall the five M2.5 x 12-mm screws in the holes labeled "circle K."
