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 when the computer gets hot. 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.
hard drive — Stores software and data.
