12 Quick Reference Guide

Transferring Information to a New Computer
You can use your operating system wizards to help you transfer files and other
data from one computer to another computer.
Microsoft Windows XP
The Microsoft
Windows XP operating system provides the Files and Settings
Transfer Wizard to transfer data, such as:
• E-mail messages
• Toolbar settings
•Window sizes
• Internet bookmarks
You can transfer data from one computer to another computer over a network
or serial connection, or by storing the data on removable media, such as
a writable CD or DVD.
NOTE: You can transfer information from one computer to another computer by
directly connecting a serial cable to the input/output (I/O) ports of the two computers. To
transfer data over a serial connection, you must use the Network Connections
utility in the Control Panel to perform additional configuration steps, such as setting
up an advanced connection and designating the host computer and the guest computer.
For instructions on setting up a direct cable connection between two computers,
see Microsoft Knowledge Base Article #305621, titled How to Set Up a Direct Cable
Connection Between Two Computers in Windows XP. This information may not be
available in certain countries.
Using the Files and Settings Transfer Wizard requires the Operating System
disc that came with your computer or a wizard disk, which the wizard can
create for you.
NOTE: For more information about transferring data, search support.dell.com for
document #154781 (What Are The Different Methods To Transfer Files From My Old
Computer To My New Dell™ Computer Using the Microsoft Windows XP Operating
System?).
NOTE: Access to the Dell Knowledge Base document may not be available in
certain countries.

Power Protection Devices
Several devices are available to protect against power fluctuations and failures:
• Surge protectors
• Line conditioners
• Uninterruptible power supplies (UPS)
16 Quick Reference Guide

Surge Protectors
Surge protectors and power strips equipped with surge protection help prevent
damage to your computer from voltage spikes that can occur during electrical
storms or after power interruptions. Some surge protector manufacturers include
warranty coverage for certain types of damage. Carefully read the device warranty
when choosing a surge protector and compare joule ratings to determine the
relative effectiveness of different devices. A device with a higher joule rating
offers more protection.
NOTICE: Most surge protectors do not protect against power fluctuations or
power interruptions caused by nearby lightning strikes. When lightning occurs in
your area, disconnect the telephone line from the telephone wall jack and
disconnect your computer from the electrical outlet.
Many surge protectors have a telephone jack for modem protection. See the
surge protector documentation for modem connection instructions.
NOTICE: Not all surge protectors offer network adapter protection. Disconnect the
network cable from the network wall jack during electrical storms.
Line Conditioners
NOTICE: Line conditioners do not protect against power interruptions.
Line conditioners are designed to maintain AC voltage at a fairly constant level.
Uninterruptible Power Supplies
NOTICE: Loss of power while data is being saved to the hard drive may result in
data loss or file damage.
NOTE: To ensure maximum battery operating time, connect only your computer to
a UPS. Connect other devices, such as a printer, to a separate power strip that
provides surge protection.
A UPS protects against power fluctuations and interruptions. UPS devices contain
a battery that provides temporary power to connected devices when AC power
is interrupted. The battery charges while AC power is available. See the UPS
manufacturer documentation for information on battery operating time and to
ensure that the device is approved by Underwriters Laboratories (UL).
