3. Remove the heat sink:
a. Loosen one captive screw fully; then, loosen the other captive screw.
Attention: Loosening one screw fully before loosening the other screw will
help to break the thermal bond that adheres the heat sink to the
microprocessor.
b. Pull the heat sink off of the microprocessor.
4. Rotate the locking lever on the microprocessor socket from its closed and
locked position until it stops or clicks in the fully open position.
5. Pull the microprocessor out of the socket.
To install a microprocessor, see “Installing a microprocessor” on page 39. To reuse
the heat sink that was removed in step 3 above, see “Thermal grease” on page 55.
