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). The securing clip hooks over tabs on the sides of the socket. socket. Leave the release lever extended so that the socket is ready for the new microprocessor. microprocessor chip securing clip press here to release securing clip Figure 6-9. Microprocessor Heat Sink 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 out until the chip is released (see Figure 6-10). Then remove the chip from the release lever microprocessor socket Figure 6-10. Removing the Microprocessor 5. Unpack the new microprocessor. CAUTION: Ground yourself by touching an unpainted metal surface on the back of the computer. CAUTION: Be careful not to bend any of the pins when unpacking the microprocessor. Bending the pins can permanently damage the microprocessor. If any of the pins on the chip appear to be bent, see the chapter titled "Getting Help" in your Diagnostics and Troubleshooting Guide for instructions on obtaining technical assistance. 6. Align the pin-1 corner of the microprocessor chip (see Figure 6-11) with the pin-1 corner of the microprocessor socket (see Figure 6-12). NOTE: Identifying the pin-1 corners is critical to positioning the chip correctly. Installing System Board Options 6-7

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.

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 out until the chip is released
(see Figure 6-10). Then remove the chip from the
socket. Leave the release lever extended so that the
socket is ready for the new microprocessor.

5.
Unpack the new microprocessor.
If any of the pins on the chip appear to be bent, see
the chapter titled “Getting Help” in your

for instructions on
obtaining technical assistance.
6.
Align the pin-1 corner of the microprocessor chip
(see Figure 6-11) with the pin-1 corner of the
microprocessor socket (see Figure 6-12).
NOTE: Identifying the pin-1 corners is critical to
positioning the chip correctly.
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.
