Use this connector to attach your computer to a television.
Air Vent
HINT: The computer turns on the fans only when the computer gets hot. They
may run most of the time or very seldom, depending on your use of the
computer. Because the fans spin at a high rate of speed, they may make a
noise. This noise is normal and does not indicate a problem with the fans or the
computer.
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. Doing so can damage the computer or cause a fire.
Back View
NOTICE: To avoid damaging the computer, wait 5 seconds after turning off the

Conserving Power
Dell™ Inspiron™ 4100
Conservation Tips
Power Conservation Modes
Power Options Properties
Conservation Tips
● You automatically conserve battery power each time you attach your computer
to an electrical outlet. When the AC adapter is attached, the battery is charged
while the computer uses AC power. Your battery's life expectancy is largely
determined by the number of times it is charged, so use an AC power source to
run the computer if one is available.
● When the computer is using battery power, remove the PC Cards that you are
not using.
● When possible, attach your computer to an electrical outlet when you play CDs
and DVDs. Playing a CD or DVD uses a lot of battery power.
● Place the computer in standby mode or hibernate mode when you leave the
computer unattended for long periods of time.
Power Conservation Modes
Standby Mode
Standby mode conserves power by turning off the display and the hard drive after a
predetermined period of inactivity (a time-out). When you exit standby mode, the
desktop is restored to the same state that it was in before the computer entered
file:///F|/Service%20Manuals/Dell/Inspiron/4100/power.htm (1 of 10) [2/28/2004 7:03:51 AM]
Conserving Power: Dell Inspiron 4100
standby mode.
To activate standby mode:
● Click the Start button, click Shut down (Turn Off Computer in the Microsoft®
Windows® XP Home Edition operating system), click Stand by, and then click
OK.
or
● Press the power button or the power conservation key combination,
, that you can program via the Advanced tab.
HINT: You can use the Advanced tab to program the display-close option, the
power button, and the power conservation key combination to activate standby
mode.
To exit standby mode, press the power button, or if you activated standby mode by
closing the display, open (raise) the display.
Hibernate Mode
Hibernate mode conserves power by copying system data to a reserved area on the
hard drive and then completely turning off the computer. When you exit hibernate
mode, the programs and files that were open before you activated hibernate mode are
still open.
Your computer enters hibernate mode if the battery charge level becomes critically
low, or if either the power button, the power conservation key combination,
, or the display-close option are programmed to activate hibernate mode in the
Advanced tab of the Power Options Properties window.
HINT: Some PC Cards may not operate correctly after exiting hibernate mode.
If you encounter problems with a PC Card, reinsert the card or restart your
computer.

Conserving Power: Dell Inspiron 4100
To exit hibernate mode, press the power button. The computer may take a short time
to exit hibernate mode. Pressing a key or touching the touch pad or track stick does
not bring the computer out of hibernate mode.
Hibernate mode requires a special file on your hard drive with enough disk space to
store the contents of the computer memory. Dell creates an appropriately sized
hibernate mode file before shipping the computer to you.
