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.
Figure 6-10. Removing the Microprocessor
6. 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.
7. 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.
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.
Figure 6-11. Pin-1 Identification
The pin-1 corner of the socket is the corner to your
left
and closest to the
front
of the chassis as you face
the front of the computer (see Figure 6-1).
8. Install the microprocessor chip in the socket (see
Figure 6-12).
If the release lever on the microprocessor socket is
not all the way up, move it to that position now.
With the pin-1 corners of the chip and socket
aligned, align the pins on the chip with the holes in
the socket. Set the chip lightly in the socket and
make sure all pins are headed into the correct holes.
Because your system uses a ZIF microprocessor
socket, there is
no need to use force
(which could
bend the pins if the chip is misaligned). When the
chip is positioned correctly, it should drop down into
the socket with minimal pressure.
CAUTION: Be careful not to bend any of the
pins when unpacking the microprocessor.
Bending the pins can permanently damage the
microprocessor.

CAUTION: Positioning the microprocessor
chip incorrectly in the socket can permanently
damage the chip and the computer when you
turn on the system.
CAUTION: When placing the microprocessor
chip in the socket, be sure that all of the pins go
into the corresponding holes on all sides of the
socket. Be careful not to bend the pins.
