NOTE: The thermal material must be thoroughly cleaned from the surfaces of the fan/heat sink

and system board components. Thermal grease is used on the video chip (1) and the surface of

the fan/heat sink (1) that contacts the video chip. Thermal tape is used on the processor (2) and

the surface of the fan/heat sink (2) that contacts the processor. Replacement thermal material is

included with all fan/heat sink and system board spare part kits.

Reverse this procedure to install the fan/heat sink.

NOTE: 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.
