battery charge gauge — Provides information on the battery charge. See " Using a Battery ."
battery — When a battery is installed, you can use the computer without connecting the computer to an electrical outlet. See " Using a Battery ."

information.
fan — The computer uses an internal fan to create airflow through the vents, which prevents the computer from overheating.
Mini PCI card cover — Covers the compartment that contains the Mini PCI card. See " Adding and Replacing Parts ."
hard drive — Stores software and data.
CAUTION: Your computer features Undock & Go™ technology that allows you to undock your computer without going into standby mode. Because
the computer may not automatically go into standby mode when it is undocked, be sure the settings in the Power Options control panel do not
prohibit the computer from going into standby mode. If you change the Power Options control panel to prohibit the computer from going into
standby mode, you greatly increase the chances of causing your battery to wear down quickly or causing your computer to overheat.
NOTE: The computer turns on the fan when the computer gets hot. Fan noise is normal and does not indicate a problem with the fans or the computer.
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.
