Attention:
• Do not press the microprocessor into the socket.
• Do not touch exposed pins of the microprocessor socket. The pins on the socket are fragile.
Any damage to the pins may require replacing the system board.
• Make sure that the microprocessor is oriented and aligned correctly in the socket before
you try to close the microprocessor retainer.
• Do not touch the thermal material on the bottom of the heat sink or on top of the
microprocessor. Touching the thermal material will contaminate it and destroys its
even distribution. If the thermal material on the microprocessor or heat sink becomes
contaminated, you must replace the thermal grease.
3. Remove the microprocessor dust cover and store it in a safe place.
4. Close the microprocessor bracket frame.
5. Close the microprocessor release lever by pressing down on the end, moving it back under the
release lever holder underneath the microprocessor bracket.

Step 6. Install the heat sink that comes with the microprocessor:
Attention:
• Do not set down the heat sink after you remove the plastic cover.
• Do not touch the thermal material on the bottom of the heat sink. Touching the thermal material
will contaminate it. If the thermal material on the microprocessor or heat sink becomes
contaminated, contact your service technician.
1. Remove the plastic protective cover from the bottom of the heat sink.
Attention: Do not touch the thermal grease on the bottom of the heat sink after you remove
the plastic cover. Touching the thermal grease will contaminate it. See “Thermal grease”
on page 76 for more information.
2. Align the screws on the heat sink with the screw holes on the system board; then, place the
heat sink on the microprocessor with the thermal-grease side down.
