3. Remove the microprocessor from its connector.
Your microprocessor uses a zero insertion force (ZIF) socket with a lever-type handle that secures or releases the microprocessor.
To remove the microprocessor, pull the socket lever straight up until the microprocessor is released. Then remove the microprocessor from the socket (see the
following figure).
Removing the Microprocessor
Replacing the Microprocessor
1. Install the new microprocessor in the socket:
a. Ensure that the lever on the microprocessor socket is fully extended to the release position.
b. Align pin 1 of the new microprocessor with pin 1 of the socket.
c. Carefully set the microprocessor in the socket and press it down lightly to seat it.
d. Rotate the socket lever back toward the socket until it snaps into place, securing the microprocessor.
Replacing the Microprocessor
NOTICE: When you place the microprocessor in the socket, ensure that the microprocessor aligns properly with the socket. You must position the
microprocessor correctly in the socket to avoid damage.
NOTE: Pin 1 of the microprocessor is indicated by a small dot or a triangle in one corner of the microprocessor. Pin 1 of the socket is indicated by a
small triangle in one corner of the socket. See " Replacing the Microprocessor ."
