NOTICE: Read "Preparing to Work Inside the Computer" before performing
the following procedure.
1Remove the memory module cover.
2To release a memory module from its socket, spread apart the inner
tabs of the memory module socket just far enough for the memory
module to disengage from the socket. The module should pop up
slightly.
3Lift the memory module out of its socket.
Replacing the Memory Modules
1If you only have one memory module, install it in the socket labeled
“JDIM1.” Install a second memory module in the socket labeled
“JDIM2.”
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.
2Align the memory module’s edge connector with the slot in the center
of the memory module socket. With the module at a 45-degree angle,
press the memory module’s edge connector firmly into the memory
module socket.
3Pivot the memory module down until it clicks into place. If you do not
hear a click, remove the memory module and reinstall it.
4Insert the tabs on the memory module cover into the bottom case
assembly. Rotate the memory module cover down and tighten the two
captive screws.
Mini-PCI Card Assembly
You must remove the optional mini-PCI card assembly before the system
boardassembly can be removed. A mini-PCI card assembly may consist of a
modem, a NIC, a modem and NIC combination, or a wireless NIC. A
modem, NIC, or modem and NIC combination must be connected to the
wiring harness as appropriate; a wireless NIC must be connected to the
system’s internal antenna.
