    • Six 2.5 mm Phillips on either side of the keyboard area.

    • Carefully disconnect the microphone and power cables from the logic board. Using your fingernails or a dental pick, carefully pry the connectors from their sockets. Make sure you're pulling only on the connector and not on the socket.
