Fan 813798-001
NOTE: To properly ventilate the computer, allow at least 7.6 cm (3.0 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 aected by
high external temperatures, system power consumption, power management/battery conservation
congurations, battery fast charging, and software requirements. Exhaust air is displaced through the
ventilation grill located on the left side of the computer.

1. Shut down the computer. If you are unsure whether the computer is o 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 rst 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 27).
5. Remove the optical drive (see Optical drive on page 28).
