Figure 6-9. Heat Sink Securing Clip - Dell OptiPlex GXi Reference And Installation Manual

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 know-
ledgeable 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 Electro-
static 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).

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 perma-
nently 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.
