8-12 Installation and Troubleshooting Guide
Microprocessor and Heat Sink Assembly Replacement
To install the replacement microprocessor and heat sink assembly, see Figure 8-10
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 8-10).

over the thermal grease by pulling on the cover's tab.
