About Your Computer 25
MEMORY MODULE COVER —Covers the compartment that contains the secondary memory module. See "Memory"
on page129.
BATTERY —When a battery is installed, you can use the computer without connecting the computer to an
electrical outlet. See "Using a Battery" on page55.
BATTERY CHARGE GAUGE —Identifies the amount of charge remaining in the battery. See "Charge Gauge" on
page60.
BATTERY LATCH RELEASE —Releases the battery. See "Replacing the Battery" on page55 for instructions.
SUBWOOFER COVER —Covers the compartment that contains the subwoofer.
FAN AIR VENTS —The computer uses an internal fan to create airflow through the fan air vents, which prevents the
computer from overheating.
NOTE: The computer turns on the fan to keep the computer within proper functioning temperature. Fan noise is
normal and does not indicate a problem with the fan 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.
