NOTE: This procedure covers removing and replacing the memory module
located under the memory module/modem cover on the bottom of the
computer. A second memory module resides on the upper surface of the system
board under the critical component shield. To replace the memory module
under the critical component shield, perform the procedure for removing the
palm rest up to and including removal of the critical component shield. Then
replace the memory module.
NOTICE: Disconnect the computer and any attached devices from electrical
outlets, and remove any installed batteries.
NOTICE: To avoid ESD, ground yourself by using a wrist grounding strap or
by touching an unpainted metal surface on the computer.
NOTE: Memory modules are keyed, or designed to fit into their sockets, in
only one direction.
NOTICE: The memory module must be inserted at a 45-degree angle to avoid
damaging the connector.
Align the notch in the memory module with the slot in the center of
the socket.
Slide the edge connector of the module firmly into the socket at a 45-
degree angle, and rotate the module down until you hear a click. If you
do not hear the click, remove the module and reinstall it.
Replace the cover and tighten the two captive screws.
Connect the modem cable to the modem daughter card.
NOTICE: The connectors are keyed for correct insertion; do not force the
connections.
Using the screw hole and the boss at the opposite corner of the
daughter card to align the card, press the card into its connector on the
system board.
Install the M2 x 4-mm screw that secures the modem to the system
board.
