Fan/heat sink ✎ The fan/heat sink assembly spare kit includes replacement thermal material. Description For use only with computer models equipped with discrete graphics subsystems For use only with computer models equipped with UMA graphics subsystems Removal and replacement procedures Spare part number 532141-001 532142-001 ✎ 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, 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 4-7). 5. Remove the following components: a. Optical drive (see "Optical drive" on page 4-9) b. Hard drive (see "Hard drive" on page 4-15) c. Switch cover and keyboard (see "Switch cover and keyboard" on page 4-20) d. Display assembly (see "Display assembly" on page 4-25) e. Top cover (see "Top cover" on page 4-30) f. USB board (see "USB board" on page 4-35) g. System board (see "System board" on page 4-37) Remove the fan/heat sink: ✎ Steps 1 through 5 apply only to models with discrete subsystem memory on the system board. Steps 6 through 10 apply only to models with UMA subsystem memory on the system board. 1. Turn the system board upside down, with the expansion port and external monitor port toward you. 2. Loosen the six Phillips PM2.5×14.0 spring-loaded, captive screws 1 through 6 that secure the fan/heat sink assembly to the system board. Ä CAUTION: Loosen the screws in the order indicated by the callouts to ensure consistent pressure over the processor board. 3. Disconnect the fan cable 7 from the system board. 4. Remove the fan/heat sink assembly 8. ✎ 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.

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-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.

Remove the fan/heat sink:
✎
Steps 1 through 5 apply only to models with discrete subsystem memory on the system board. Steps 6 through 10
apply only to models with UMA subsystem memory on the system board.
1. Turn the system board upside down, with the expansion port and external monitor port toward you.
2. Loosen the six Phillips PM2.5×14.0 spring-loaded, captive screws
1
through
6
that secure the fan/heat sink
assembly to the system board.
Ä
CAUTION:
Loosen the screws in the order indicated by the callouts to ensure consistent pressure over the processor board.
3. Disconnect the fan cable
7
from the system board.
4. Remove the fan/heat sink assembly
