Fan/heat sink
✎The fan/heat sink assembly spare kit includes replacement thermal material.
✎To properly ventilate the computer, allow at least a 7.6-cm (3-in) 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 heat sink, 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.
3. Disconnect the power from the computer by first unplugging the power cord from the AC outlet and then 
unplugging the AC adapter from the computer.

3. In the order indicated on the fan/heat sink, loosen the seven Phillips captive screws 2 that secure the fan/heat 
sink assembly to the system board.
4. Remove the fan/heat sink assembly 3.
✎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.
✎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.
