Heat sink

Description Spare part number

Heat sink (includes thermal material) 530614-001

NOTE: 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.

NOTE: Thermal pads and thermal paste are included with all heat sink, system board, and processor

spare part kits.

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.

4. Remove the battery (see

Battery on page 34).

5. Remove the following components:

a. Hard drive (see

b. Optical drive (see

c. Keyboard (see

f. Display assembly (see

g. Top cover (see

h. System board (see

Remove the heat sink:

1. Turn the system board upside down with the external monitor port toward you.

2. Loosen the four Phillips PM2.0×10.0 captive screws (1) that secure the heat sink to the system

board.

NOTE: Due to the adhesive quality of the thermal material located between the heat sink and

system board components, it may be necessary to move the heat sink from side to side to detach

the assembly.
