1 Install the Operating System

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

operating system is successfully installed. Doing so may cause errors and may prevent the
operating system from installing properly. Once the automatic installation has begun, DO NOT
TURN OFF THE COMPUTER UNTIL THE PROCESS IS COMPLETE. Turning off the computer
during the installation process might damage the software that runs the computer or prevent its
proper installation.

NOTE: Be sure there is a 10.2-cm (4-inch) clearance at the back of the unit and above the

monitor to permit the required airflow.

The first time the computer is turned on, the operating system is automatically installed. This takes
approximately 10 minutes, depending on the operating system being installed. Carefully read and follow
the instructions that appear on the screen to complete the installation.

NOTE: If the computer shipped with more than one operating system language on the hard

drive, the installation process could take up to 60 minutes.

If the computer was not shipped with a Microsoft operating system, some portions of this documentation
do not apply. For complete operating system installation and configuring instructions, refer to the
operating system documentation. Additional information is available in online help.

Microsoft security updates are available on the Microsoft Web site.

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.

If prompted for the i386 directory, replace the path specification with C:\i386, or use the Browse button
in the dialog box to locate the i386 folder. This action points the operating system to the appropriate
drivers.

Obtain the latest support software, including support software for the operating system from

http://www.hp.com/support. Select your country and language, select Download drivers and

software, enter the model number of the computer, and press Enter.

Transferring Files and Settings

Use the Microsoft Windows XP Professional/Home Files and Settings Transfer Wizard to move files and
settings from the old computer to the new one. Click Start > All Programs > Accessories > System

HP Backup and Recovery Manager

The HP Backup and Recovery Manager is an easy-to-use, versatile application that is pre-loaded on
each system and allows you to:

create Recovery Points to back up the entire system incrementally

●

back up the entire system in a single hard archive

●

back up individual files

●

Backups can be scheduled to occur automatically at designated intervals, or they can be initiated
manually. Recovery can be performed from the Recovery Partition on the hard drive or the Recovery
Disc Set. The Recovery Disc Set includes the Restore Plus! CD, the Microsoft Operating System, and
any Supplemental Software CDs.

NOTE: HP highly recommends that you create a Recovery Disc Set immediately before using

the computer and schedule regular automatic Recovery Point backups.

To create the Recovery Disc Set:

1. Click Start > HP Backup and Recovery > HP Backup and Recovery Manager to open the

Backup and Recovery Wizard, then click Next.

2. Select Create factory software recovery CDs or DVDs to recover the system.

3. Follow the instructions in the wizard.

The HP Backup and Recovery Manager provides two basic recovery methods. The first, recovery of
files and folders, operates in Windows. The second, PC Recovery, requires a reboot to the Recovery
Partition or from the Recovery Disc Set. To reboot to the Recovery Partition, press F11 at startup when
you see the message “Press F11 for Emergency Recovery.”

NOTE: For more information on using HP Backup and Recovery Manager, refer to the HP

Backup and Recovery Manager User Guide by selecting Start > HP Backup and Recovery >

Recovering the Configuration Settings

Recovering the configuration settings established in the Computer Setup (F10) Utility requires that you
first back up the settings before a recovery is needed.

The CMOS Save/Load utility can be found at
for your specific model. Download the firmware files into a folder on a removable storage device. It is
recommended that you save any modified computer configuration settings to a diskette, a USB flash
media device, or a diskette-like device (a storage device set to emulate a diskette drive) and save the
diskette or device for possible future use.

Backing Up the CMOS

1. Make sure the computer to be backed up is turned on. Connect the removable storage to the

computer.

2. Boot to DOS.

3. Type N:\folder\BIOS.exe SAVE:ABC001.DAT (where N is the drive letter of the removable

storage) to save the CMOS setting to the removable storage device.

Restoring the CMOS

1. Make sure the target computer is turned on. Connect the removable storage to the target computer.

2. Boot to DOS.

3. Type N:\folder\BIOS.exe LOAD:ABC001.DAT (where N is the drive letter of the removable

storage) to load the custom CMOS setting onto the target system.

HP Backup and Recovery Manager

CAUTION: HP no longer ships the Restore Plus! CD set with PCs. Instead, HP Backup and

Recovery Manager is pre-loaded on each system. HP recommends that you create a recovery
CD set as soon as you have set up the new computer. Creating the Restore Plus! CD set is
important in the event that you ever need to restore the system hard drive to its factory installed
state.

HP Backup and Recovery Manager can create the Restore Plus! CD set. This set includes the Restore
Plus! CD, the Operating System CD, and any Supplemental Software CDs.

CAUTION: The Restore Plus! CD set will not include any system settings or user data created

after the initial system setup.

To create the Restore Plus! CD set:

1. Click Start > HP Backup and Recovery > HP Backup and Recovery Manager to open the

Backup and Recovery Wizard, then click Next.

2. Select Create factory software recovery CDs or DVDs to recover the system.

3. Follow the instructions in the wizard.

In addition to allowing you to create the Restore Plus! CD set, HP Backup and Recovery Manager can
be used to back up data and system files to the hard drive, to network drives, or to removable media,
such as CDs, DVDs, or flash media. If data or system files are lost, deleted, or corrupted, Backup and
Recovery Manager allows you to retrieve data or restore the last good system image.

CAUTION: HP recommends that a backup schedule be created immediately to ensure

continued system and data protection. Automatic backups can be scheduled using the HP
Backup and Recovery Manager Wizard. Recovery Points, Entire Drive Backups, and File
Backups can be automatically backed up without user intervention. HP recommends scheduling
Recovery Point Backups to provide the most comprehensive coverage.

NOTE: If HP Backup and Recovery Manager is preinstalled, the Restore Plus! CD set and the

initial recovery point may be saved to disc as often as necessary, but only a single copy of the
Microsoft Windows CD can be created, due to licensing constraints.

You can access a user manual at Start > HP Backup and Recovery > HP Backup and
Recovery Manager Manual. We suggest that you print this document for easy reference in case
of future emergency.

If Create factory software recovery CDs or DVDs to recover the system is unavailable on
your system, the HP Restore Plus! CD set can be obtained through product support on

HP Client Management Interface

Regardless of the system management tools your IT department uses, managing both your hardware
and software assets is important to keeping your IT costs low and your business agile.

With the HP Client Management Interface (HP CMI), new HP business computers seamlessly integrate
into your managed IT environment. HP CMI provides an interface that simplifies the integration of HP
business computers with popular industry system management tools (including Microsoft Systems
Management Server, IBM Tivoli Software, and HP OpenView Operations) and custom inhouse
developed management applications. Using HP CMI, systems management tools and applications can
request in-depth client inventory, receive health status information, and manage system BIOS settings
by communicating directly with the client computer, reducing the need for agent or connector software
to achieve integration.

24 Chapter 4 Desktop Management ENWW

NOTE: The system management tools mentioned above do not automatically connect into HP

CMI. Some script development is typically required to interface with HP CMI.

HP Client Management Interface is based on industry standards that include Microsoft Windows
Management Interface (MS WMI), Web-Based Enterprise Management (WBEM), System Management
BIOS (SMBIOS), and Advanced Configuration and Power Interface (ACPI). HP CMI is a foundation
technology utilized in HP Client Management Solutions. With HP CMI, HP gives you flexibility in choosing
how you manage your HP client computers.

HP Client Management Interface used in conjunction with system management software can:

Request in-depth client inventory information—Capture detailed information about the processors,

●

hard drives, memory, BIOS, drivers, including sensor information (such as fan speed, voltage, and
temperature)

Receive health status information—Subscribe for a wide range of client hardware alerts (such as

●

over-temperature, fan stall, and hardware configuration changes) to be sent to the system
management console, application, or to the local client computer. Alerts are sent real-time when
triggered by hardware events.

Manage system BIOS settings—Perform F10 functions including setting and changing the BIOS

●

passwords and computer boot order remotely from your system management console on any or
all of your client systems without having to visit each machine.

HP System Software Manager

HP System Software Manager (SSM) is a free utility that automates remote deployment of device drivers
and BIOS updates for your networked HP business PCs. When SSM runs, it silently (without user
interaction) determines the revision levels of drivers and BIOS installed on each networked client system
and compares this inventory against system software SoftPaqs that have been tested and stored in a
central file store. SSM then automatically updates any down-revision system software on the networked
PCs to the later levels available in the file store. Since SSM only allows distribution of SoftPaq updates
to the correct client system models, administrators can confidently and efficiently use SSM to keep
system software updated.

System Software Manager integrates with enterprise software distribution tools such as HP OpenView
Management Suite using Radia and Microsoft Systems Management Server (SMS). Using SSM, you
can distribute customer-created or third-party updates that have been packaged in the SSM-format.

SSM may be downloaded at no charge by visiting

HP Client Manager

HP Client Manager, developed with Altiris, is available free for all supported HP business desktop,
notebook, and workstation models. SSM is integrated into HP Client Manager, and enables central
tracking, monitoring, and management of the hardware aspects of HP client systems.

ROM Flash

The computer's BIOS is stored in a programmable flash ROM (read only memory). By establishing a
setup password in the Computer Setup (F10) Utility, you can protect the ROM from being unintentionally
updated or overwritten. This is important to ensure the operating integrity of the computer. Should you
need or want to upgrade the BIOS, you may download the latest BIOS images from the HP driver and
support page,

http:///www.hp.com/support/files.

http://h30046.www3.hp.com/subhub.php.

28 Chapter 4 Desktop Management ENWW

CAUTION: For maximum ROM protection, be sure to establish a setup password. The setup

password prevents unauthorized ROM upgrades. System Software Manager allows the system
administrator to set the setup password on one or more PCs simultaneously. For more
information, visit

Remote ROM Flash

Remote ROM Flash allows the system administrator to safely upgrade the BIOS on remote HP
computers directly from the centralized network management console. Enabling the system
administrator to perform this task remotely on multiple computers results in a consistent deployment of,
and greater control over, HP PC BIOS images over the network. It also results in greater productivity
and lower total cost of ownership.

NOTE: The computer must be powered on, or turned on through Remote Wakeup, to take

advantage of Remote ROM Flash.

For more information on Remote ROM Flash, refer to the HP Client Manager Software or System
Software Manager at

HPQFlash

The HPQFlash utility is used to locally update or restore the system BIOS of individual PCs from a
Windows operating system.

Boot Block Emergency Recovery Mode

Boot Block Emergency Recovery Mode permits system recovery in the unlikely event of a ROM flash
failure. For example, if a power failure were to occur during a BIOS upgrade, the ROM flash would be
incomplete. This would render the system BIOS unusable. The Boot Block is a flash-protected section
of the ROM that contains code that checks for a valid system BIOS image when the system is turned
on.

If the system BIOS image is valid, the system starts normally.

●

If the system BIOS image is not valid, a failsafe Boot Block BIOS provides enough support to

●

search removable media for BIOS image files. If an appropriate BIOS image file is found, it is

●

automatically flashed into the ROM.

start the system from bootable removable media that automatically invokes system BIOS

●

upgrade utilities.

When an invalid system BIOS image is detected, the system power LED will blink red 8 times, one blink
every second. Simultaneously, the speaker will beep 8 times. If the portion of the system ROM containing
the video option ROM image is not corrupt, Boot Block Emergency Recovery Mode will be displayed
on the screen.

ENWW Boot Block Emergency Recovery Mode 29

To recover the system after it enters Boot Block Emergency Recovery Mode, complete the following
steps:

1. Turn off the power.

2. Insert a diskette, CD, or USB flash device containing the desired BIOS image file in the root

directory.

NOTE: The media must be formatted using the FAT12, FAT16, or FAT32 file system.

3. Turn on the computer.

If no appropriate BIOS image file is found, the failsafe Boot Block BIOS will attempt to start the
system from a bootable device. If no bootable device is found, you will be prompted to insert media
containing a BIOS image file or BIOS upgrade utility.

If the system successfully reprograms the ROM, the system will automatically power off.

4. Remove the removable media used to upgrade the BIOS.

5. Turn the power on to restart the computer.

Replicating the Setup

The following procedures give an administrator the ability to easily copy one setup configuration to other
computers of the same model. This allows for faster, more consistent configuration of multiple
computers.

NOTE: Both procedures require a diskette drive or a supported USB flash media device, such

as an HP Drive Key.

Copying to Single Computer

CAUTION: A setup configuration is model-specific. File system corruption may result if source

and target computers are not the same model. For example, do not copy the setup configuration
from a dc7xxx PC to a dx7xxx PC.

1. Select a setup configuration to copy. Turn off the computer. If you are in Windows, click Start >

Shut Down > Shut Down.

2. If you are using a USB flash media device, insert it now.

Password Security

The power-on password prevents unauthorized use of the computer by requiring entry of a password
to access applications or data each time the computer is turned on or restarted. The setup password
specifically prevents unauthorized access to Computer Setup, and can also be used as an override to
the power-on password. That is, when prompted for the power-on password, entering the setup
password instead will allow access to the computer.

When this feature is enabled, the user is prompted to provide one of the
DriveLock passwords during POST. If neither is successfully entered, the
hard drive will remain inaccessible until one of the passwords is successfully
provided during a subsequent cold-boot sequence.

NOTE: This selection will only appear when at least one ATA drive

that supports the ATA Security command set is attached to the
system.

See the Computer Setup (F10) Utility Guide on the Documentation and
Diagnostics CD for more information.

A network-wide setup password can be established to enable the system administrator to log in to all
network systems to perform maintenance without having to know the power-on password, even if one
has been established.

DriveLock

DriveLock is an industry-standard security feature that prevents unauthorized access to the data on ATA
hard. DriveLock has been implemented as an extension to Computer Setup. It is only available when
hard drives that support the ATA Security command set are detected. DriveLock is intended for HP
customers for whom data security is the paramount concern. For such customers, the cost of the hard
drive and the loss of the data stored on it is inconsequential when compared with the damage that could
result from unauthorized access to its contents. In order to balance this level of security with the practical
need to accommodate a forgotten password, the HP implementation of DriveLock employs a two­password security scheme. One password is intended to be set and used by a system administrator
while the other is typically set and used by the end-user. There is no "back-door" that can be used to
unlock the drive if both passwords are lost. Therefore, DriveLock is most safely used when the data

www.hp.com.

ENWW Asset Tracking and Security 41

contained on the hard drive is replicated on a corporate information system or is regularly backed up.
In the event that both DriveLock passwords are lost, the hard drive is rendered unusable. For users who
do not fit the previously defined customer profile, this may be an unacceptable risk. For users who do
fit the customer profile, it may be a tolerable risk given the nature of the data stored on the hard drive.

Using DriveLock

When one or more hard drives that support the ATA Security command set are detected, the DriveLock
option appears under the Security menu in Computer Setup. The user is presented with options to set
the master password or to enable DriveLock. A user password must be provided in order to enable
DriveLock. Since the initial configuration of DriveLock is typically performed by a system administrator,
a master password should be set first. HP encourages system administrators to set a master password
whether they plan to enable DriveLock or keep it disabled. This will give the administrator the ability to
modify DriveLock settings if the drive is locked in the future. Once the master password is set, the system
administrator may enable DriveLock or choose to keep it disabled.

If a locked hard drive is present, POST will require a password to unlock the device. If a power-on
password is set and it matches the device’s user password, POST will not prompt the user to re-enter
the password. Otherwise, the user will be prompted to enter a DriveLock password. On a cold boot,
either the master or the user password may be used. On a warm boot, enter the same password used
to unlock the drive during the preceding cold-boot. Users will have two attempts to enter a correct
password. On a cold boot, if neither attempt succeeds, POST will continue but the drive will remain
inaccessible. On a warm boot or restart from Windows, if neither attempt succeeds, POST will halt and
the user will be instructed to cycle power.

DriveLock Applications

The most practical use of the DriveLock security feature is in a corporate environment. The system
administrator would be responsible for configuring the hard drive which would involve, among other
things, setting the DriveLock master password and a temporary user password. In the event that the
user forgets the user password or the equipment is passed on to another employee, the master
password can always be used to reset the user password and regain access to the hard drive.

HP recommends that corporate system administrators who choose to enable DriveLock also establish
a corporate policy for setting and maintaining master passwords. This should be done to prevent a
situation where an employee intentionally or unintentionally sets both DriveLock passwords before
leaving the company. In such a scenario, the hard drive would be rendered unusable and require
replacement. Likewise, by not setting a master password, system administrators may find themselves
locked out of a hard drive and unable to perform routine checks for unauthorized software, other asset
control functions, and support.

For users with less stringent security requirements, HP does not recommend enabling DriveLock. Users
in this category include personal users or users who do not maintain sensitive data on their hard drives
as a common practice. For these users, the potential loss of a hard drive resulting from forgetting both
passwords is much greater than the value of the data DriveLock has been designed to protect. Access
to Computer Setup and DriveLock can be restricted through the Setup password. By specifying a Setup
password and not giving it to end users, system administrators are able to restrict users from enabling
DriveLock.

Fault Notification and Recovery

Fault Notification and Recovery features combine innovative hardware and software technology to
prevent the loss of critical data and minimize unplanned downtime.

If the computer is connected to a network managed by HP Client Manager, the computer sends a fault
notice to the network management application. With HP Client Manager Software, you can also remotely
schedule diagnostics to automatically run on all managed PCs and create a summary report of failed
tests.

Drive Protection System

The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in some HP
computers. DPS is designed to help diagnose problems that might result in unwarranted hard drive
replacement.

When HP computers are built, each installed hard drive is tested using DPS, and a permanent record
of key information is written onto the drive. Each time DPS is run, test results are written to the hard
drive. You can use this information to help diagnose conditions that caused you to run the DPS software.
Refer to the Troubleshooting Guide on the Documentation and Diagnostics CD for instructions on using
DPS.

Surge-Tolerant Power Supply

An integrated surge-tolerant power supply provides greater reliability when the computer is hit with an
unpredictable power surge. This power supply is rated to withstand a power surge of up to 2000 volts
without incurring any system downtime or data loss.

Thermal Sensor

The thermal sensor is a hardware and software feature that tracks the internal temperature of the
computer. This feature displays a warning message when the normal range is exceeded, which gives

PATA Device Information

This model supports PATA drives.

ATA SMART Drives

The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal
Computers have built-in drive failure prediction that warns the user or network administrator of an
impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure
indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If
the drive determines that a failure is imminent, it generates a fault alert.

Hard Drive Capacities

The combination of the file system and the operating system used in the computer determines the
maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may be
properly accessed by the operating system. A single hard drive may therefore be subdivided into a
number of unique drive partitions in order to make use of all of its space.

Because of the differences in the way that drive sizes are calculated, the size reported by the operating
system may differ from that marked on the hard drive or listed in the computer specification. Drive size
calculations by drive manufacturers are bytes to the base 10 while calculations by Microsoft are bytes
to the base 2.

Electrostatic Discharge Information

A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work
perfectly throughout a normal cycle. The device may function normally for a while, but it has been
degraded in the internal layers, reducing its life expectancy.

Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.

Generating Static

The following table shows that:

Different activities generate different amounts of static electricity.

Operating Guidelines

To prevent overheating and to help prolong the life of the computer:

Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.

●

Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented

●

sides of the computer and above the monitor to permit the required airflow.

Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the

●

keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.

Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign

●

matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning
the air vents.

Never operate the computer with the cover or side panel removed.

●

Do not stack computers on top of each other or place computers so near each other that they are

●

subject to each other’s re-circulated or preheated air.

If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must

●

be provided on the enclosure, and the same operating guidelines listed above will still apply.

Keep liquids away from the computer and keyboard.

●

Never cover the ventilation slots on the monitor with any type of material.

●

Install or enable power management functions of the operating system or other software, including

●

sleep states.

Routine Care

General Cleaning Safety Precautions

1. Never use solvents or flammable solutions to clean the computer.

2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then

use the cloth on the component.

●

For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a

●

cloth or swab dampened with clear water.

For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will

●

evaporate quickly and not leave a residue.

After cleaning, always wipe the unit with a clean, lint-free cloth.

●

Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents

●

and limit the airflow.

Cleaning the Keyboard

Follow all safety precautions in General Cleaning Safety Precautions on page 55 before cleaning the
keyboard.

To clean the tops of the keys or the keyboard body, follow the procedures described in

Computer Case on page 55.

When cleaning debris from under the keys, review all rules in

on page 55 before following these procedures:

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris

from under the keys.

Visible debris underneath or between the keys may be removed by vacuuming or shaking.

●

Canned, pressurized air may be used to clean debris from under the keys. Caution should be used

●

as too much air pressure can dislodge lubricants applied under the wide keys.

If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool

●

is available through many electronic supply outlets.

CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If

these keys are improperly removed or installed, the keyboard may not function properly.

Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed

●

out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to
remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.

Cleaning the Monitor

Cleaning the

General Cleaning Safety Precautions

Wipe the monitor screen with a clean cloth moistened with water or with a towelette designed for

●

cleaning monitors. Do not use sprays or aerosols directly on the screen; the liquid may seep into
the housing and damage a component. Never use solvents or flammable liquids on the monitor.

hard drives only.

CAUTION: As each subassembly is removed from the computer, it should be placed away from

the work area to prevent damage.

ENWW Service Considerations 57

Cables and Connectors

Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care
to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal
from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or
twisting the cables, and ensure that the cables are routed in such a way that they cannot be caught or
snagged by parts being removed or replaced.

CAUTION: When servicing this computer, ensure that cables are placed in their proper location

during the reassembly process. Improper cable placement can damage the computer.

Hard Drives

Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This
applies to failed drives as well as replacement spares.

If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective

●

packaging and label the package “Fragile: Handle With Care.”

Do not remove hard drives from the shipping package for storage. Keep hard drives in their

●

protective packaging until they are actually mounted in the CPU.

Avoid dropping drives from any height onto any surface.

●

If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard drive

●

while the computer is on or in standby mode.

Before handling a drive, ensure that you are discharged of static electricity. While handling a drive,

●

avoid touching the connector. For more information about preventing electrostatic damage, refer
