NOTE: The fan and heat sink spare part kits include replacement thermal material.

Description	Spare part number

Fan	680551-001

Heat sink for use only with computer models equipped with UMA video memory	683027-001

Heat sink for use only with computer models equipped with Discrete video memory	683028-001

NOTE: To properly ventilate the computer, allow at least 7.6 cm (3 in) of 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 and 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 32).

5.Remove the service door (see Service door on page 33).

6.Remove the optical drive (see Optical drive on page 34).

7.Remove the hard drive (see {Xref Error! Target does not exist.})

8.Remove the keyboard (see Keyboard on page 43).

9.Remove the top cover (see Top cover on page 47).

10.Remove the system board (see System board on page 64).

Remove the fan and heat sink:

1.Turn the system board upside down, with the front toward you.

2.Disconnect the fan cable (1) from the system board.

CAUTION: To prevent damage to heat sinks and/or processors, loosen/tighten captive screws in sequence as numerically labeled.

NOTE: The heat sink and fan appearance and the number of screws may be different from the heat sink and fan pictured.

3.Loosen the four Phillips captive screws (2) and the three Phillips captive screws (3) that secure the heat sink to the system board.
