Microprocessor and Heat-Sink Assembly Replacement
To install the replacement microprocessor and heat-sink assembly, see Figure 19 and perform the
following steps:
1. Remove the microprocessor and heat sink assembly.
2. Gently place the replacement microprocessor into the ZIF socket so that the processor pins mate
exactly with the ZIF socket.
Make certain that pin 1 of the microprocessor is oriented correctly in the socket.
CAUTION: Do not force the processor into the socket. Even slight pressure can bend the
microprocessor pins.
3. With the microprocessor in place, swing the ZIF socket arm down until it snaps into the socket tab
(see Figure 20).
