The following items are included in a microprocessor upgrade kit: • The new microprocessor chip • A new heat sink with thermal interface adhesive The following procedure describes how to replace the microprocessor. NOTE: Dell recommends that only a technically knowledgeable person perform this procedure. 1. Remove the computer cover according to the instructions in "Removing the Computer Cover" in Chapter 5. CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions at the front of this guide. 2. Rotate the power supply out of the way according to the instructions in "Rotating the Power Supply Away From the System Board" in Chapter 5. 3. See Figure 6-1 to locate the microprocessor socket (labeled "MICROPROCESSOR") on the system board. 4. Remove the metal clip that secures the heat sink to the microprocessor socket. Then remove the heat sink from the microprocessor chip. Press down on the folded part of the clip with a small screwdriver to release the clip (see Figure 6-9). The securing clip hooks over tabs on the sides of the socket. press here to release securing clip securing clip Figure 6-9. Microprocessor Heat Sink 5. Remove the microprocessor chip from the socket. CAUTION: Be careful not to bend any of the pins when removing the microprocessor chip from its socket. Bending the pins can permanently damage the microprocessor chip. Your microprocessor socket is a zero insertion force (ZIF) socket with a lever-type handle that secures the chip in, or releases it from, the socket. Installing System Board Options 6-7

The following items are included in a microprocessor
upgrade kit:
•
The new microprocessor chip
•
A new heat sink with thermal interface adhesive
The following procedure describes how to replace the
microprocessor.
NOTE:
Dell recommends that only a technically knowl-
edgeable person perform this procedure.
1.
Remove the computer cover according to the
instructions in “Removing the Computer Cover”
in Chapter 5.
2.
Rotate the power supply out of the way according
to the instructions in “Rotating the Power Supply
Away From the System Board” in Chapter 5.
3.
See Figure 6-1 to locate the microprocessor socket
(labeled “MICROPROCESSOR”) on the system
board.
4.
Remove the metal clip that secures the heat sink
to the microprocessor socket. Then remove the
heat sink from the microprocessor chip.
Press down on the folded part of the clip with a small
screwdriver to release the clip (see Figure 6-9). The
securing clip hooks over tabs on the sides of the
socket.
Figure 6-9.

5.
Remove the microprocessor chip from the socket.
Your microprocessor socket is a zero insertion force
(ZIF) socket with a lever-type handle that secures the
chip in, or releases it from, the socket.
CAUTION:
See “Protecting Against Electro-
static Discharge” in the safety instructions at
the front of this guide.
CAUTION:
Be careful not to bend any of the
pins when removing the microprocessor chip
from its socket.
Bending the pins can perma-
nently damage the microprocessor chip.
