Removing Memory Modules
1.
Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2.
Remove the cover (see "
Removing the Cover
" in "Troubleshooting Your System").
3.
Lay the system on its right side.
4.
Locate the memory module connectors from which you will remove memory modules (see
Figure A
-3
).
5.
Press down and outward on the memory module connector ejectors until the memory module pops out of the connector (see
Figure 6
-4
).
6.
Repeat
step 4
and
step 5
of this procedure to remove any other memory modules.
7.
Perform
step 5
through
step 10
of "
Performing a Memory Upgrade
."
Microprocessors
To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the primary or secondary
microprocessor.
Each microprocessor and its associated cache memory are contained in a PGA package that is installed in a ZIF socket on the system board.
The following items are included in the microprocessor upgrade kit:
l
A microprocessor
l
A heat sink with cooling fan
Removing and Installing a Microprocessor
1.
Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2.
Remove the cover (see "
Removing the Cover
" in "Troubleshooting Your System").
3.
Lay the system on its right side.
4.
If you are removing or installing a microprocessor in socket CPU2, remove the vertical plastic baffle to improve access to the microprocessor socket (see
"
Removing the Baffle
" in "Troubleshooting Your System").
5.
Disconnect the microprocessor fan cable from the fan power connector on the system board (see
Figure 6
-5
).
To identify system board connectors, see
Figure A
-3
.
6.
Remove the back system fan (see "
Removing the Back System Fan
").
CAUTION:
Before you perform this procedure, see "
Safety First
—
For You and Your System
" in "Troubleshooting Your System."
CAUTION:
See "Protecting Against Electrostatic Discharge" in the safety instructions in your
System Information Guide
.
NOTE:
The second microprocessor must be of the same type as the first. If the two microprocessors are different speeds, both will operate at the
speed of the slower microprocessor.
CAUTION:
Before you perform this procedure, see "
Safety First
—
For You and Your System
" in "Troubleshooting Your System."
CAUTION:
See "Protecting Against Electrostatic Discharge" in the safety instructions in your
System Information Guide
.
CAUTION:
The microprocessor and heat sink can become extremely hot. Be sure they have had sufficient time to cool before handling.
NOTICE:
Do not operate the system without the fan and heat sink assembly installed. The assembly is required to maintain proper thermal conditions.
NOTICE:
After removing the fan and heat sink assembly, place it upside down on a flat surface to prevent the thermal interface material on the heat
sink from being damaged or contaminated.
NOTICE:
The microprocessor fan and heat sink are constructed together as a single assembly. Do not attempt to remove the fan from the heat sink.
