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.

4. 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 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.
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.
