5. Press down on the folded part of the clip with a small screwdriver to release the clip (see Figure 30).
The securing clip hooks over tabs on the sides of the socket.
6. 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 32). Then remove the chip
from the socket. Leave the release lever extended so that the socket is ready for the new microprocessor.

7. Unpack the new microprocessor.
If any of the pins on the chip appear to be bent, see the online User's Guide for instructions on obtaining technical assistance.
8. Align the pin-1 corner of the microprocessor chip with the pin-1 corner of the microprocessor socket (see Figure 33).
The pin-1 corner of the microprocessor is the squared off corner (see Figure 33).

9. Install the microprocessor chip in the socket (see Figure 33).
If the release lever on the microprocessor socket is not all the way out, 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
NOTICE: Be careful not to bend any of the pins when removing the microprocessor from its socket. Bending the pins can
permanently damage the microprocessor.

CAUTION: Ground yourself by touching an unpainted metal surface on the back of the computer.
NOTICE: Be careful not to bend any of the pins when unpacking the microprocessor. Bending the pins can permanently damage
the microprocessor.
NOTE: Identifying the pin-1 corners is critical to positioning the chip correctly.

CAUTION: Ground yourself by touching an unpainted metal surface on the back of the computer.
NOTICE: Positioning the microprocessor chip incorrectly in the socket can permanently damage the chip and the computer
when you turn on the system.
NOTICE: 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.
