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.

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
