Installing Memory Modules
1
Open the system. See "Opening the System" in Troubleshooting Your System."
2
Locate the memory module sockets. See Figure 6-1.
3
Press the ejectors on the memory module socket down and out, as shown in Figure 6-12, to
allow the memory module to be inserted into the socket.
4
Align the memory module's edge connector with the alignment keys of the memory module
socket, and insert the memory module in the socket.
NOTE: The memory module socket has two alignment keys that allow you to install the memory
module in the socket in only one way.
5
Press down on the memory module with your thumbs while pulling up on the ejectors with
your index fingers to lock the memory module into the socket.
When the memory module is properly seated in the socket, the ejectors on the memory
module socket align with the ejectors on the other sockets that have memory modules
installed.
6
Repeat step 2 through step 5 of this procedure to install the remaining memory modules. See
Table 6-1 for installing the total desired memory.
7
Close the system. See "Closing the System" in "Troubleshooting Your System."
8
(Optional) Press <F2> to enter the System Setup program, and check the
System Memory
setting on the main
System Setup
screen.
The system should have already changed the value to reflect the newly installed memory.
9
If the value is incorrect, one or more of the memory modules may not be installed properly.
Repeat step 1 through step 8 of this procedure, checking to ensure that the memory modules
are firmly seated in their sockets.
10
Run the system memory test in the system diagnostics. See "Running the System
Diagnostics."
