A Tour of Your Computer 29
Bottom View
MODEM/MINI PCI CARD COVER Covers the compartment that contains the modem and
Mini PCI card. See page102.
BATTERY/BATTERY BAY When a battery is installed, you can use the computer without
connecting the computer to an electrical outlet. See page41.
AIR VENTS The computer uses an internal fan to create airflow through the vents, which
prevents the computer from overheating.
CAUTION: Do not block, push objects into, or allow dust to accumulate in the air
vents. Do not store your computer in a low-airflow environment, such as a closed
briefcase, while it is running. Restricting the airflow can damage the computer
or cause a fire.
NOTE: The fan runs constantly, and fan speed may vary depending on usage. Fan noise is
normal and does not indicate a problem with the fan or the computer.
