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.

NOTICE: To avoid damaging the computer, wait 5 seconds after turning off the computer

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 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

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.
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.
Power Options Properties
To access the Windows Power Options Properties window:
Windows XP
1. Click the Start button, and then click Control Panel.

Using System Restore
Windows XP and Windows Me provide a System Restore feature that allows you to return your
computer to an earlier operating state if changes to the computer hardware or software (including new
hardware or program installations) or system settings have left the computer in an undesirable
operating state. You can also undo the last System Restore procedure.
System Restore automatically creates system checkpoints. You can also manually create your own
checkpoints by creating restore points. To limit the amount of hard disk space used, older restore
points are automatically purged.
file:///I|/SERVICE%20MANUALS/DELL%20MANUALS/LA...0ok/Inspiron/4100/4100_SERVICE_MAN/solving.htm (24 of 32)6/21/2004 1:02:20 AM
Solving Problems: Dell Inspiron 4100
To resolve an operating system problem, you can use System Restore from Safe Mode or Normal Mode
to return your computer to an earlier operating state.
System Restore does not cause you to lose personal files stored in the My Documents folder, data
files, or e-mail messages after restoring the computer to an earlier operating state. If you restore the
computer to an operating state that existed before you installed a program, for example, the
program's data files will not be lost, but you will have to reinstall the actual program.
NOTICE: It is important to make regular backups of your data files. System Restore does not
monitor changes to or recover your data files. If the original data on the hard disk is
accidentally erased or overwritten, or if the data becomes inaccessible because of a hard disk
malfunction, use your backup files to recover the lost or damaged data.
System Restore is enabled on your new computer. However, if you reinstall Windows XP or Windows
Me with less than 200 MB of free hard-disk space available, System Restore is automatically disabled.
Before you use System Restore, see the following subsections to confirm that it is enabled.
Windows XP
1. Click the Start button and then click Control Panel.

When to Use the Dell Diagnostics
Whenever a major component or device in your computer does not function properly, you may have a
component failure. If you are experiencing a problem with your computer, Dell recommends that you
perform the checks in "Solving Problems" and run the Dell Diagnostics before you contact Dell for
technical assistance.
As long as the microprocessor and the display, keyboard, and CD or DVD drive are working, you can
use the Dell Diagnostics. Running the Dell Diagnostics may help you to resolve the problem yourself
quickly without having to contact Dell for assistance.
If you are experienced with computers and know what component(s) you need to test, simply select
the appropriate diagnostic test group(s) or subtest(s). If you are unsure about how to begin
diagnosing a problem, see "Starting the Dell Diagnostics" and "Advanced Testing."
Features of the Dell Diagnostics
The Dell Diagnostics helps you check your computer hardware without any additional equipment and
without destroying any data. By using the diagnostics, you can have confidence in your computer's
operation. And if you find a problem you cannot solve by yourself, the diagnostic tests can provide you
with important information you will need when talking to Dell's service and support personnel. If you
are experiencing a problem with your computer, Dell recommends that you perform the checks in
"Solving Problems" and run the Dell Diagnostics before you contact Dell for technical assistance.

Menu
Provides descriptions of the main menu screen area, the device groups, and the
different diagnostic menus and commands and instructions on how to use them.
Keys
Explains the functions of all the keystrokes that can be used in the Dell Diagnostics.
Device group
Describes the test group that is presently highlighted in the Device Groups list on
the main menu screen. It also provides reasoning for using some tests.
Device
Describes the function and purpose of the highlighted device in the Device Groups
list. For example, the following information appears when you select the Device
Help category for Diskette in the Device Groups list:
Diskette
Drive A
The diskette disk drive device reads and writes data to and from
diskettes. Diskettes are flexible recording media, sometimes contained
in hard shells. Diskette recording capacities are small and access
times are slow relative to hard disk drives, but they provide a
convenient means of storing and transferring data.
Test
Provides a thorough explanation of the test procedure of each highlighted test
group subtest. An example of the Diskette subtest floppy drive Seek Test is as
follows:
Diskette
Drive A - floppy drive Seek Test
This test verifies the drive's ability to position its read/write
heads. The test operates in two passes: first, seeking from the
beginning to ending cylinders inclusively, and second, seeking
alternately from the beginning to ending cylinders with convergence
towards the middle.
Versions
Lists the version numbers of the subtests that are used by the Dell Diagnostics.

Using the Dell™ Diagnostics: Dell Inspiron 4100
Confirming the System Configuration Information
When you boot your computer from your Drivers and Utilities CD, the diagnostics checks your system
configuration information and displays it in the Device Groups area on the main menu screen.
The following sources supply this configuration information for the diagnostics:
●
●
●
The system configuration information settings (stored in NVRAM) that you selected while using
the system setup program
Identification tests of the microprocessor, the video controller, the keyboard controller, and
other key components
BIOS configuration information temporarily saved in RAM
Do not be concerned if the Device Groups area does not list the names of all the components or
devices you know are part of your computer. For example, you may not see a printer listed, although
you know one is attached to your computer. Instead, the printer is listed as a parallel port. The
computer recognizes the parallel port as LPT1, which is an address that tells the computer where to
send outgoing information and where to look for incoming information. Because your printer is a
parallel communications device, the computer recognizes the printer by its LPT1 address and identifies
it as a parallel port. You can test your printer connection in the Parallel Ports tests.
