A Tour of Your Computer: Dell Inspiron 4150
Display Latch — Keeps the display closed.
Keyboard Status Lights — The green lights located above the keyboard indicate the following:
Turns on when the numeric keypad is enabled
Turns on when the caps lock function is enabled

Air Vent — The computer uses an internal fan to create airflow through the vents, which prevents the
computer from overheating.
HINT: The computer turns on the fans when the computer gets hot. The fans may make noise, which 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.
