Press down on the folded part of the clip with a small
screwdriver to release the clip (Figure 7-8).

4. Remove the heat sink.
The thermal interface pad is bonded to the heat sink
and will remain with the old 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 perma-
nently damage the microprocessor chip.
To remove the microprocessor chip, pull the socket
release lever straight up until the chip is released (Fig-
ure 7-9). Then lift the chip out of the socket. Leave the
release lever up so that the socket is ready for the new
microprocessor.

6. Unpack the new microprocessor.
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 microprocessor chip appear
to be bent, see the chapter titled "Getting Help" in
your Diagnostics and Troubleshooting Guide for instruc-
tions on obtaining technical assistance.
7. Align the pin-1 corner of the microprocessor chip
(Figure 7-10) with the pin-1 corner of the micro-
processor socket.
NOTE: Identifying the pin-1 corners is critical to
positioning the chip correctly.
Identify the pin-1 corner of the microprocessor by
turning the chip over and locating the tiny gold fin-
ger that extends from one corner of the large central
rectangular area. The gold finger points toward
pin 1, which is also uniquely identified by a square
pad.
