### Replacing the Keyboard

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

1. Connect the keyboard connector to the interface connector on the system board.

The keyboard connector may have a label on it that shows the correct orientation of the keyboard connector to the interface connector on the system board.

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

1. Rotate the keyboard back and fit it into the bottom case.

Ensure that all four securing tabs are engaged in their respective slots before trying to completely seat the keyboard. Fitting the tabs to the slots may be easiest when viewed from above and slightly behind the front edge of the keyboard. Press down on the left and right keys to help control tab/slot alignment.

When the keyboard appears to be completely seated, confirm that the front edge of the keyboard is aligned with the edge of the palm rest before proceeding.

1. Check that the keyboard is correctly installed. The keys should be flush with the left and right surfaces of the palm rest.

| NOTE: The M2.5 x 4 screws are silver.

1. Replace the four M2.5 x 4-mm screws at the top of the keyboard.
2. Replace the center control cover.

Ensure that the center control cover is snapped in properly so that it is flush with the keyboard.
