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. See Figure 6-1 to locate the microprocessor socket (labeled "MICROPROCESSOR") on the system board. 3. 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). press here to release securing clip heat sink securing clip hooks over tabs on left and right sides of socket Figure 6-9. Heat Sink Securing Clip 4. 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. To remove the chip, pull the microprocessor-socket release lever straight up until the chip is released (see Figure 6-10). Then lift the chip out of the socket. Leave the release lever up so that the socket is ready for the new microprocessor. Installing System Board Options 6-7

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.
To remove the chip, pull the microprocessor-socket
release lever straight up until the chip is released (see
Figure 6-10). Then lift the chip out of the socket.
Leave the release lever up so that the socket is ready
for the new microprocessor.
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.
