For use only with computer models equipped with T7700 and T7500 processors 450370-001
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.
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 36).
5.Remove the following components:
a.Hard drives (see 
Hard drives on page 41)
b.Optical drive (see 
Optical drive on page 47)
c.Switch cover (see

the fan/heat sink assembly to the system board.
4.Remove the fan/heat sink assembly (4).
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 (1) and (2), the Northbridge chip (3), and the processor (4) each time the fan/heat sink
assembly is removed. Thermal material must be installed on all surfaces before the fan/heat sink
assembly is reinstalled. Replacement thermal material is included with all fan/heat sink assembly,
system board, and processor spare part kits.
5.If it is necessary to replace the processor bracket, turn the system board upside down, with the
expansion port 3 and external monitor port toward you.
