WARNING: Before working inside your computer, read the safety information
that shipped with your computer. For additional safety best practices information,
see the Regulatory Compliance Homepage at

WARNING: If you remove the processor heat sink from the computer when the
heat sink is hot, do not touch the metal housing of the processor heat sink.
CAUTION: Only a certified service technician should perform repairs on your

by your warranty.
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist
grounding strap or by periodically touching an unpainted metal surface (such as a
connector on your computer).
CAUTION: To help prevent damage to the system board, remove the main battery
(see Removing the Battery) before working inside the computer.
Disconnect the fan cable from the system board connector.
Loosen the four captive screws that secure the processor heat sink to the
system board in sequential order (indicated next to the captive screws).

Replacing the Processor Heat Sink
NOTE: The original thermal pad can be reused if the original processor and
processor heat sink are reinstalled together. If either the processor or processor
heat sink is replaced, use the thermal pad provided in the kit to ensure that thermal
conductivity is achieved.
NOTE: This procedure assumes that you have already removed the processor heat
sink and are ready to replace it.
Align the four captive screws on the processor heat sink with the screw
holes on the system board and tighten the screws in sequential order
(indicated next to the captive screws).
Connect the fan cable to the system board connector.
CAUTION: Before turning on the computer, replace all screws and ensure that no
stray screws remain inside the computer. Failure to do so may result in damage to
the computer.
