Installing the Microprocessor Thermal-Cooling Assembly
NOTICE: Before you install the replacement microprocessor thermal-cooling assembly, remove the
mylar that covers the thermal grease on the assembly.
If you are installing a replacement microprocessor thermal-cooling assembly, remove the mylar
that covers the thermal grease on the assembly. If you are installing the assembly that you
removed in the previous section:
Wipe the thermal grease off of the microprocessor thermal-cooling assembly with a clean
paper towel.
Squeeze the contents of the thermal grease packet (provided with the kit) onto the
microprocessor thermal-cooling assembly.
Place the back of the microprocessor thermal-cooling assembly under the palm rest, and lower
the assembly onto the system board.
Tighten the four captive screws, labeled "1" through "4," in consecutive order.
