Installing or Replacing Parts and Accessories
Processor
Chapter 10 176
8. Remove the two heatsink clips by pressing the release lever on the
clips. Then lift off the heatsink. There is a thermal interface material
between the heatsink and the processor. This may cause the processor
to stick to the heatsink.
Figure 10-21 Removing a Processor
9. Remove the thermal interface material from the heatsink and discard
it. You can leave any residue that remains on the heatsink. This does
not impair the heat transfer.
10. Open the Zero Insertion Force (ZIF) lever, located at the side of the
processor socket, until it is in the vertical position (depending on the
socket design, the handle may need to go past vertical), then carefully
lift out the processor. To avoid bending the processor pins, keep the
processor perfectly flat when removing it.
11. Store the processor in an anti-static bag (such as the one provided
with the replacement processor).
12. If you are permanently removing a second processor, you must update
your operating system (see page 179). You should also store the
heatsink and clips in a safe place.
