4.
Replace the computer cover, reconnect your com-
puter and peripherals to their power sources, and
turn them on.
After the system completes the power-on self-test
(POST) routine, the system runs a memory test that
displays the total memory of all installed SIMMs,
including those you just installed. If you hear a beep
code, the SIMM is installed incorrectly.
NOTE: If the memory total is incorrect, turn off and
disconnect your computer and peripherals from their
power sources, remove the computer cover, and
make sure that the installed SIMMs are seated prop-
erly in their sockets. Then repeat this step.
The system detects that the new memory does not
match the existing system configuration information,
which is stored in nonvolatile random-access mem-
ory (NVRAM), and generates the following
message:
The amount of system memory has
changed.
Strike the F1 key to continue, F2 to
run the setup utility
5.
Press <
F2
> to enter the System Setup program,
and check the
SYSTEM MEMORY
category in the
lower-right corner of Page 1.
The system should have already changed the value in
the
SYSTEM MEMORY
category to reflect the newly
installed memory. Verify the new total.
NOTES: The value of
SYSTEM MEMORY
is given in
kilobytes. To convert kilobytes to megabytes, divide
the kilobyte total by 1024.
If the memory total is incorrect, turn off and dis-
connect your computer and peripherals from their
power sources, remove the computer cover, and
check the installed SIMMs to make sure that they are
seated properly in their sockets. Then repeat steps 4
and 5.
6.
When the
SYSTEM MEMORY
total is correct, press
the <
ESC
> key to exit the System Setup program.
7.
Run the Dell diagnostics to verify that the SIMMs
are operating properly.
See your Diagnostics and Troubleshooting Guide for
information on running the diskette-based
diagnostics and troubleshooting any problems that
may occur.
Installing a SIMM
NOTE: In the following instructions, left and right refer
to your left and right as you face the front of the com-
puter. See Figure 5-5 to orient yourself.
When installing SIMMs, begin with socket SIMM_A.
Use the following procedure to install a SIMM:
1.
See Figure 6-7 to locate the cutout area on one
corner of the SIMM.
2.
Hold the SIMM at a 45-degree angle (as shown in
Figure 6-7) and with the cutout facing the left side
of the chassis. Align the SIMM's edge connector
with the slot in the center of the SIMM socket.
3.
Press the SIMM's edge connector firmly into the
SIMM socket.
4.
Pivot the SIMM upward until it clicks into place.
You should hear a click as the plastic tabs at each
end of the socket snap into place around the SIMM
and the small retention pegs snap into the holes at
each end of the SIMM.
If you have misaligned or only partially seated the
SIMM, you will not hear a sharp click and the reten-
tion pegs will not snap cleanly into the holes. You
can easily remove the SIMM (see the next sub-
section, “Removing a SIMM”) and reinstall it.
5.
Continue with step 4 of “Performing a Memory
Upgrade” found earlier in this section.
