10. Remove the chip from the socket. Leave the release lever extended so that the socket is ready for the new microprocessor.
11. Unpack the new microprocessor.
If any of the pins on the chip appear to be bent, obtain technical assistance.
12. Align the pin-1 corner of the microprocessor chip with the pin-1 corner of the microprocessor socket, as shown in the following illustration.
The pin-1 corner of the microprocessor is the beveled corner. The pin-1 corner of the socket is marked with a white triangle on the system board.
13. Install the microprocessor chip in the socket (as shown in the preceding illustration):
a. If the release lever on the microprocessor socket is not all the way out, move it to that position.
b. With the pin-1 corners of the chip and socket aligned, align the pins on the chip with the holes in the socket.
c. Set the chip lightly in the socket and make sure that all pins are headed into the correct holes. Because your system uses a ZIF microprocessor
socket, you do not need to use force, which could bend the pins if the chip is misaligned. When the chip is positioned correctly, press it with
minimal pressure to seat the microprocessor in the socket. Be careful not to bend the pins.
d. When the chip is fully seated in the socket, pivot the microprocessor-socket release lever back toward the socket until it snaps into place,
securing the chip.
14. Unpack the heat sink and fan assembly included in your upgrade kit.
15. Peel the release liner from the adhesive tape that is attached to the bottom of the heat sink and fan assembly.
16. Replace the heat sink and fan assembly:
a. Place the heat sink and fan assembly on top of the microprocessor chip.
b. Orient the securing clip and hook the shorter side of the clip over the tab on the top edge of the microprocessor socket.
NOTICE: Be careful not to bend any of the pins when you remove the microprocessor chip from its socket. Bending the pins can permanently damage
the microprocessor chip.
NOTICE: 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 you unpack the microprocessor. Bending the pins can permanently damage the microprocessor.
HINT: You must identify the pin-1 corner to correctly position the chip.
NOTICE: You must position the microprocessor chip correctly in the socket to avoid permanent damage to the chip and the computer when you turn on
the system.
NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.
NOTICE: When you install the heat sink and fan assembly, make sure that the heat sink is flat against the surface of the processor while you are
installing the clip. If the heat sink becomes tilted when you install the clip, excess heat can damage the processor.
