Replacing the Palm Rest

To aid with proper flex cable connection, a locator line has been added near the end of the palm-rest flex cable. When replacing the palm-rest flex cable, press the cable into the connector until the line aligns with the system board and hold it steady while you snap the ZIF connector down. (The locator line may reappear after the connector is closed, which should not indicate a problem with the connection.)
