Adding or Replacing a Microprocessor
CAUTION:
Before you perform this procedure, you must turn off the system and disconnect it from its
power source. For more information, 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
document.
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").
If you are installing a second microprocessor, go to step 6.
NOTE:
The system is designed to allow you to remove the microprocessor heat sink without removing the
microprocessor cooling fan. However, you can remove the fan to provide easier access to the heat sink (see
"
Removing a Cooling Fan
").
3. Remove the microprocessor heat sink:
a. Press down on the heat-sink securing clips to release the clips from the retaining tabs on the ZIF socket (see
Figure 6-7
).
b. Remove the heat sink securing clips.
CAUTION:
The microprocessor and heat sink can become extremely hot. Be sure the microprocessor has
had sufficient time to cool before handling.
NOTICE:
Never remove the heat sink from a microprocessor unless you intend to remove the microprocessor. The
heat sink is required to maintain proper thermal conditions.
c. Remove the heat sink.
