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

3. Turn the computer over, and insert a ¼-inch flat-blade screwdriver into the slot to the right of the keyboard locator tab.

Replacing the Keyboard

1. Place the keyboard face-down on the palm rest, with the keyboard flex cable pointing toward the back of the computer.
   
   

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

2. Ensure that the ZIF connector is open by pulling the ZIF connector tabs toward the back of the computer.
   
   
3. Press the keyboard flex cable into the ZIF connector.
   
   
4. Close the ZIF connector by pushing the ZIF connector tabs toward the front of the computer.
   
   

To aid with proper flex cable connection, a blue locator line has been added near the end of the flex cable. Press the cable into the connector until the blue line disappears and hold the cable steady while you close the ZIF connector. (The blue line may reappear after the connector is closed, which should not indicate a problem with the connection.)

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

5. Rotate the keyboard back and fit it into the bottom case.
   
   
6. Ensure that all four keyboard securing tabs are engaged in their respective slots before trying to completely seat 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.

7. Replace the six M2 x 4-mm screws on the bottom of the computer.
