6. Align the memory-module's edge connector with the alignment key of the memory-module socket,
and insert the memory module in the socket.
NOTE: The memory-module socket has an alignment key that allows you to install the memory
module in the socket in only one orientation.
CAUTION: To prevent damage to the memory-module socket during installation, apply
pressure at both ends of the memory module evenly. Do not apply pressure to the center of
the memory module.
7. Press down on the memory module with your thumbs until the memory module snaps into place.

steps 4 through 7 of this procedure, checking to make sure that the memory modules are firmly
seated in their sockets.
14. Run the appropriate diagnostic test. For more information, see Using System Diagnostics in this
