Installing & Customizing the Software

CAUTION: Do not add optional hardware or third-party devices to the

Ä

computer until the operating system is successfully installed. Doing so may
cause errors and prevent the operating system from installing properly.

Getting Started

Installing the Operating System

The first time you turn on the computer, the operating system is
installed automatically. This process takes about 5 to 10 minutes,
depending on which operating system is being installed. Carefully
read and follow the instructions on the screen to complete the
installation.

CAUTION: Once the automatic installation has begun, DO NOT TURN

Ä

OFF THE COMPUTER UNTIL THE PROCESS IS COMPLETE. Turning off the
computer during the installation process may damage the software that
runs the computer or prevent its proper installation.

If your computer was not shipped with a Microsoft operating system,
some portions of this documentation do not apply. For complete
operating system installation and configuration instructions, refer to
the operating system documentation that was provided with the
computer . Additional information is a v ailable in online help after you
install the operating system.

Accessibility

HP is committed to designing products, services, and programs with
improved usability and accessibility for all customers. HP products
with Microsoft Windows XP preinstalled, or that are XP Ready, are

www.hp.com 1

337845-001.book Page 2 Friday, July 18, 2003 4:02 PM

Getting Started

designed for accessibility. These products are tested with
industry-leading Assistive Technology products to ensure equal
access—anytime, anywhere . . . to anyone.

Installing or Upgrading Device Drivers

When installing optional hardware devices after the operating system
installation is complete, you must also install the drivers for each of
the devices.

In Microsoft Windows 2000 and Windows XP Professional, if
prompted for the I386 directory, replace the path specification with

C:\i386, or use the Browse b utton in the dialog box to locate the I386

folder. This action points the operating system to the appropriate
drivers.

✎

If the computer is running Microsoft Windows XP Embedded, you
will need to obtain new hardware drivers from the hardware
manufacturer.

You can obtain the latest support software, including support software
for the operating system from:

www.hp.com/support

You can also obtain the latest support software through a subscription
to the Compaq Support CD Kit using the Support Software
Management order form available at the following Web site:

http://www.compaq.com/support/files/desktops/us/
purchase.html

This site also provides information on how to purchase a subscription.

Customizing the Monitor Display

You can manually select or change the monitor model, refresh rates,
screen resolution, color settings, font sizes, and power management
settings. To do so, right-click on the Windows Desktop, then click
Properties to change display settings. For more information, refer to
the online documentation provided with the graphics controller utility
or the documentation that came with your monitor.

2 www.hp.com

337845-001.book Page 3 Friday, July 18, 2003 4:02 PM

Protecting the Software

To protect the software from loss or damage, you should keep a
backup copy of all system software, applications, and related files
stored on the hard drive. Refer to the operating system or backup
utility documentation for instructions on making backup copies of
your data files.

Restoring the Software

Restore the original operating system and factory-installed software
by using the Restore Plus! CD and any other CDs that came with the
computer. Carefully read and follow the instructions provided for the
restore solution that came with the computer.

Getting Started

For questions about or problems with this CD, please contact
customer support.

Turning Off the Computer

To properly turn off the computer, first shut down the operating
system software. Click Start > Shut Down. The computer
automatically shuts down.

Depending on the operating system, pressing the power button causes
the computer to enter a low-power or “standby” state instead of
automatically turning the power off. This allows you to conserve
energy without closing software applications; later, you can start
using the computer immediately without having to restart the
operating system and without losing any data.

CAUTION: Manually forcing the computer off can cause loss of data.

Ä

T o turn of f power to the computer , press and hold the po wer button for
four seconds. However, manually turning off the power bypasses the
standby state and can result in loss of data.

To reconfigure the power button to work in On/Off mode, run
Computer Setup. Refer to the Computer Setup Guide on the
Documentation Library CD for more information about using the
Computer Setup utility.
