Fan/heat sink assembly
✎The fan/heat sink assembly spare part kit includes replacement thermal material.
✎To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the left side 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. 
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. 
4. Remove the battery (see “Battery” on page 6). 
5. Remove the following components: 
a. Hard drive (see “Hard drive” on page 8)
b. Memory module (see “Memory module” on page 10)
c. WLAN module (see “WLAN module” on page 11)
d. WWAN module (see “WWAN module” on page 15)
e. SIM slot board (see “SIM slot board” on page 16)

							Removal and replacement procedures
Maintenance and Service Guide4–51
Remove the fan/heat sink assembly:
1. Turn the system board upside down with the front toward you.
✎Steps 2 and 3 apply to computer models equipped with graphics subsystems with discrete memory. See steps 4 
and 5 for instructions on removing the fan/heat sink assembly on computer models equipped with graphics 
subsystems with UMA memory.
2. Loosen the four captive Phillips PM2.0×7.0 screws 1 that secure the fan/heat sink assembly to the 
system board.
3. Remove the fan/heat sink assembly 2.
✎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. 
						

							4–52Maintenance and Service Guide
Removal and replacement procedures
✎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 the heat sink section 4 that services it.
■Thermal pads are used on the graphics subsystem memory module 5 and the heat sink section 6 that 
services it.
■Thermal pads are used on the other system board components 7 and heat sink sections 8 that service them.
Replacement thermal material is included with all system board, fan/heat sink assembly, and processor spare 
part kits.
