Procedure
1.With the display open and the keyboard removed, remove the T8 screw near the heat pipe.
2.Disconnect the PC card flex cable connector and the keyed battery connector.
Important: If the battery connector has not been disconnected before, the keyed connector may be tight. If necessary, use a black stick or needle nose pliers to loosen one side of the connector and then the other side. Then insert the black stick under the cables to pry up and disconnect the connector.
Replacement Note: When reassembling the computer, tuck down the battery cables so they do not get in the way when the keyboard is installed.
