CAUTION:
Despite having a plastic shield, the heat sink assembly may be very
hot during normal operation. Be sure that it has had sufficient time to cool before
you touch it.
NOTICE:
Strong thermal grease bond may exist between the processor and heat
sink. Do not use excessive force to separate the heat sink assembly from the
processor to avoid damaging the processor.
6 Rotate the heat sink assembly upward gently, and remove it from the
computer. Lay the heat sink assembly down on its top, with the thermal
grease facing upward.
NOTICE:
Unless a new heat sink is required for the new processor, reuse the
original heat sink assembly when you replace the processor.
7 Pull the release lever straight up until the processor is released.
