Removing the Old Processor
The CPU is attached to the motherboard by a SAZ (screwdriver actuated ZIF) socket.
A heat sink is attached to the top of the CPU with latch bands. Refer to Figure 1–3 for
details. To remove the old CPU, complete the following steps:
1. Turn the system off. Disconnect the power cord and all peripherals.
2. Remove the system unit cover, as described earlier.
Caution
Protect your system from ESD, as described in “Avoiding Electrostatic
Discharge,“ earlier in this section.
3. Locate the heat sink on the motherboard (see Figure 1–3).
4. As needed, remove any feature cards that block access to the heat sink.
5. Press down and then out on one end of the heat sink latch band until it clears its
keeper.
6. Press down and out on the other end of the latch band until it clears its keeper.
7. Lift the heat sink off the processor.
8. Insert a screwdriver into the indentation on the right side of the SAZ socket, see
Figure 1–3 for details. Gently but firmly swing the end of the screwdriver handle
toward the riser card while steadying the CPU.
9. Remove the processor chip from the socket.
10. Wrap the chip in antistatic material and store in a cool, dry place, in case you need
it later.
