Fan/heat sink assembly
NOTE:The fan/heat sink assembly spare kit includes replacement thermal material.
DescriptionSpare part number
For use only with computer models equipped with graphics subsystems with discrete memory516876-001
For use only with computer models equipped with graphics subsystems with UMA memory 516331-001
NOTE:To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the right side
and rear panel of the computer. The computer uses an electric fan for ventilation. The fan is controlled
by a temperature sensor and is designed to turn on automatically when high temperature conditions
exist. These conditions are affected by high external temperatures, system power consumption, power
management/battery conservation configurations, battery fast charging, and software requirements.
Exhaust air is displaced through the ventilation grill located on the left side of the computer.
Before removing the fan/heat sink assembly, follow these steps:
1.Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the
computer on, and then shut it down through the operating system.
2.Disconnect all external devices connected to the computer.

board.
90 Chapter 4   Removal and replacement procedures 
						

							4.Remove the fan/heat sink assembly (3).
NOTE:Due to the adhesive quality of the thermal material located between the fan/heat sink
assembly and system board components, it may be necessary to move the fan/heat sink assembly
from side to side to detach the assembly.
NOTE:The thermal material must be thoroughly cleaned from the surfaces of the fan/heat sink
assembly and the system board each time the fan/heat sink assembly is removed. Thermal paste
is used on the processor (1) and the heat sink section (2) that services it. Thermal pads are used
on the Northbridge chip (3) and Northbridge contact (4), the graphics subsystem chip (5) and
graphics/heat sink contact (6) and various capacitors and their contacts (7). Replacement thermal
material is included with all fan/heat sink assembly, system board, and processor spare part kits.
5.Turn the system board upside down, with the expansion port and external monitor port toward you.
