HP Backup and Recovery Manager
The HP Backup and Recovery Manager is an easy-to-use, versatile application that allows you to back
up and recover the primary hard drive on the PC. The application works within Windows to create
backups of Windows, all applications, and all data files. Backups can be scheduled to occur
automatically at designated intervals, or they can be initiated manually. Important files can be archived
separately from regular backups.
HP Backup and Recovery Manager is preinstalled on the hard drive's Recovery Partition and allows you
to:
create Recovery Points to back up the entire system incrementally
back up the entire system in a single archive
back up individual files and folders
●
●
●
Recovery Points and file backups can be copied to CD or DVD discs, while all backups can be copied
to network or secondary hard disks.
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 a set of recovery discs (Recommended) and click Next.
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.”
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 > HP Backup and Recovery
Manager Manual.
NOTE: You can order a Recovery Disc Set from HP by calling the HP support center. Go to the
following Web site, select your region, and click the Technical support after you buy link under the
Call HP heading to obtain the support center telephone number for your region.

Monitor Tracking (enable/disable). Allows BIOS to save monitor asset information.
NIC PXE Option ROM Download (enable/disable). The BIOS contains an embedded NIC option
ROM to allow the unit to boot through the network to a PXE server. This is typically used to
download a corporate image to a hard drive. The NIC option ROM takes up memory space
below 1MB commonly referred to as DOS Compatibility Hole (DCH) space. This space is
limited. This F10 option will allow users to disable the downloading of this embedded NIC option
ROM thus giving more DCH space for additional PCI cards which may need option ROM space.
The default will be to have the NIC option-ROM-enabled.
AMT Options
Allows you to set:
SOL Character Echo (enable/disable). Some remote consoles print remotely-entered
●
characters which can cause the characters to appear twice (once when entered remotely and
once when echoed back from local client video). This option allows the administrator to have
the SOL terminal emulator suppress echoing remotely-entered characters to the local video
display.
SOL Terminal Emulation Mode (enable/disable). Selects between VT100 and ANSI SOL
terminal emulation. SOL terminal emulation mode is only activated during remote AMT
redirection operations. The emulation options allow administrators to select which mode works
best with their console.
●
●
SOL Local Keyboard (enable/disable). Disable or enable client keyboard during SOL sessions.
Some remote remediation may involve having the local client boot a remote image provided by
an administrator. This option determines if the BIOS will keep the local keyboard enabled or
disabled for possible local client interaction. If the local keyboard is disabled, all keyboard input
is only accepted from the remote source.
AMT Force Unprovision (enable/disable). Forces AMT configuration back to factory defaults.
This feature allows AMT to be unprovisioned locally without having to enter the MEBx utility or
clear CMOS. Only the AMT configuration options are returned to factory defaults. Any MEBx
changes to the ME configuration or non-AMT options are unchanged.
●
Recovering the Configuration Settings
This method of recovery requires that you first perform the Save to Removable Media command with
on page 5 in the Computer Setup—File table.)

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. The IT
administrator can access the HP Client Management Interface by writing simple scripts and integrating
those scripts to the management solution of their choice.
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.
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.
24 Chapter 4 Desktop Management
Download from Www.Somanuals.com. All Manuals Search And Download.
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
PC Configuration Management Solution (not currently available for Windows Vista), Altiris HP Client
Manager, 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.
NOTE: SSM does not currently support remote ROM flash on systems that have Windows Vista
BitLocker enabled and are using TPM measurements to protect the BitLocker keys because flashing
the BIOS would invalidate the trust signature that BitLocker created for the platform. Disable BitLocker
via Group Policy in order to flash the system BIOS.
You can enable BitLocker support without TPM measurements of BIOS to avoid invalidating the
BitLocker keys. HP recommends you keep a secure backup of the BitLocker credentials in case of
recovery emergencies.
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.

HP Backup and Recovery Manager
The HP Backup and Recovery Manager is an easy-to-use, versatile application that allows you to back
up and recover the primary hard drive on the PC. The application works within Windows to create
backups of Windows, all applications, and all data files. Backups can be scheduled to occur
automatically at designated intervals, or they can be initiated manually. Important files can be archived
separately from regular backups.
HP Backup and Recovery Manager is preinstalled on the hard drive's Recovery Partition and allows you
to:
create Recovery Points to back up the entire system incrementally
back up the entire system in a single archive
back up individual files and folders

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
ROM Flash 31
Download from Www.Somanuals.com. All Manuals Search And Download.
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: SSM does not currently support remote ROM flash on systems that have Windows Vista
BitLocker enabled and are using TPM measurements to protect the BitLocker keys because flashing
the BIOS would invalidate the trust signature that BitLocker created for the platform. Disable BitLocker
via Group Policy in order to flash the system BIOS.
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

The HPQFlash utility is used to locally update or restore the system BIOS of individual PCs from a
Windows operating system.
of the computer when prompted.
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.
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.
32 Chapter 4 Desktop Management
Download from Www.Somanuals.com. All Manuals Search And Download.
To recover the system after it enters Boot Block Emergency Recovery Mode, complete the following
steps:
1. Turn off the power.
2. Insert a 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 is found, you will be prompted to insert media containing a BIOS
image file.
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.
NOTE: BitLocker prevents Windows Vista from booting when a CD containing the BIOS image file is
in an optical drive. If BitLocker is enabled, remove this CD before attempting to boot to Windows Vista.
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.

HP Web Site Support
HP engineers rigorously test and debug software developed by HP and third-party suppliers, and
develop operating system specific support software, to ensure performance, compatibility, and reliability
for HP computers.
When making the transition to new or revised operating systems, it is important to implement the support
software designed for that operating system. If you plan to run a version of Microsoft Windows that is
different from the version included with the computer, you must install corresponding device drivers and
utilities to ensure that all features are supported and functioning properly.
HP has made the task of locating, accessing, evaluating, and installing the latest support software easier.
The Web site contains the latest device drivers, utilities, and flashable ROM images needed to run the
latest Microsoft Windows operating system on the HP computer.

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.
A network-wide setup password can be established to enable the system administrator to log in to all

DriveLock
DriveLock is an industry-standard security feature that prevents unauthorized access to the data on ATA
hard drive. 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 is inconsequential compared with the loss of the data stored on it and the damage that could
result. To balance this level of security with the practical need to accommodate a forgotten password,
the HP implementation of DriveLock employs a two-password 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 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.
44 Chapter 4 Desktop Management
Download from Www.Somanuals.com. All Manuals Search And Download.
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.

PATA Device Information
The USDT model is the only product that supports a PATA optical drive. No PATA drives are supported
on any other model.
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.

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.

Cable Management
Always follow good cable management practices when working inside the computer.
Keep cables away from major heat sources like the heatsink.
●
●
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
are not designed to take excessive pressure on them.
Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when
the parts are moved.
●
●
When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the
wires.
Some flat ribbon cables come prefolded. Never change the folds on these cables.
Do not bend any cable sharply. A sharp bend can break the internal wires.
Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
Never crease a SATA data cable.
●
●
●
●
●
Do not rely on components like the drive cage, power supply, or computer cover to push cables
down into the chassis. Always position the cables to lay properly by themselves.
When removing the power supply power cables from the P1 or P3 connectors on the system board,
always follow these steps:
1. Squeeze on the top of the retaining latch attached to the cable end of the connector (1).
2. Grasp the cable end of the connector and pull it straight up (2).

Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) dual inline memory modules (DIMMs).
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 8 GB of memory configured in a
highperforming dual channel mode.
For proper system operation, the DDR2-SDRAM DIMMs must be:
industry-standard 240-pin
●
●
●
unbuffered, PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
support CAS latency 5 DDR2 667 Mhz (5-5-5 timing), CAS latency 5 DDR2 800 Mhz (5-5-5 timing),
and CAS latency 6 DDR2 800 Mhz (6-6-6 timing)
●
contain the mandatory JEDEC SPD information
●
In addition, the computer supports:
512Mbit and 1Gbit non-ECC memory technologies
single-sided and double-sided DIMMs
●
●
●
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not
supported
NOTE: The system will not operate properly if you install unsupported DIMMs.
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A.
Sockets XMM3 and XMM4 operate in memory channel B.

NOTE: A DIMM must occupy the black DIMM1 socket. Otherwise, the system
will display a POST error message indicating that a memory module must be
installed in the black socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
The system will operate in single channel mode if the DIMM sockets are populated in one channel
only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity of
the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The
technology and device width can vary between the channels. For example, if Channel A is
populated with two 512-MB DIMMs and Channel B is populated with one 1GB DIMM, the system
will operate in dual channel mode.
●
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not
equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
and the remainder is assigned to single channel. For optimal speed, the channels should be
balanced so that the largest amount of memory is spread between the two channels. If one channel
will have more memory than the other, the larger amount should be assigned to Channel A. For
example, if you are populating the sockets with one 1-GB DIMM, and three 512-MB DIMMs,
Channel A should be populated with the 1-GB DIMM and one 512-MB DIMM, and Channel B should
be populated with the two 512-MB DIMMs. With this configuration, 2-GB will run as dual channel
and 512-MB will run as single channel.
●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
●
CAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it
is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation
resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. Refer to Electrostatic Discharge Information on page 53 for more information.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.

Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 8 GB of memory configured in a high-
performing dual channel mode.
DDR2-SDRAM DIMMs
For proper system operation, the DDR2-SDRAM DIMMs must be:
industry-standard 240-pin
●
●
●
unbuffered PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
support CAS latency 5 DDR2 667 Mhz (5-5-5 timing), CAS latency 5 DDR2 800 Mhz (5-5-5 timing),
and CAS latency 6 DDR2 800 Mhz (6-6-6 timing)

Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel
A. Sockets DIMM3 and DIMM4 operate in memory channel B.

White
White
NOTE: A DIMM must occupy the black DIMM1 socket. Otherwise, the system
will display a POST error message indicating that a memory module must be
installed in the black socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
The system will operate in single channel mode if the DIMM sockets are populated in one channel
only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity of
the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The
technology and device width can vary between the channels. For example, if Channel A is
populated with two 512-MB DIMMs and Channel B is populated with one 1GB DIMM, the system
will operate in dual channel mode.
●
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not
equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
and the remainder is assigned to single channel. For optimal speed, the channels should be
balanced so that the largest amount of memory is spread between the two channels. If one channel
will have more memory than the other, the larger amount should be assigned to Channel A. For
example, if you are populating the sockets with one 1-GB DIMM, and three 512-MB DIMMs,
Channel A should be populated with the 1-GB DIMM and one 512-MB DIMM, and Channel B should

be populated with the two 512-MB DIMMs. With this configuration, 2-GB will run as dual channel
and 512-MB will run as single channel.
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
●
Installing DIMMs
CAUTION: You must disconnect the power cord before adding or removing memory modules.
Regardless of the power-on state, voltage is always supplied to the memory modules as long as the
computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is
present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation
resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. For more information, refer to Electrostatic Discharge Information on page 53.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
3. Locate the memory module sockets on the system board.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.

Cable Management
The Small Form Factor chassis is a very compact computer and proper routing of the internal cables is
critical to the operation of the computer. Follow good cable management practices when working inside
the computer.
Keep cables away from major heat sources like the heatsink.
●
●
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
are not designed to take excessive pressure on them.
Keep cables clear of movable or rotating parts like the power supply and drive cage to prevent
them from being cut or crimped when the component is lowered into its normal position.
●
●
When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the
wires.
Some flat ribbon cables come prefolded. Never change the folds on these cables.
Do not bend any cable sharply. A sharp bend can break the internal wires.
Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
Never crease a SATA data cable.
●
●
●
●
●
Do not rely on components like the drive cage, power supply, or computer cover to push cables
down into the chassis. Always position the cables to lay properly by themselves.
When removing the power supply power cables from the P1 connector on the system board, always
follow these steps:
1. Squeeze on the top of the retaining latch attached to the cable end of the connector (1).
2. Grasp the cable end of the connector and pull it straight up (2).
CAUTION: Always pull the connector - NEVER pull on the cable. Pulling on the cable could
damage the cable and result in a failed power supply.

Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) small outline dual inline memory modules (SODIMMs).
SODIMMs
The memory sockets on the system board can be populated with up to two industry-standard SODIMMs.
These memory sockets are populated with at least one preinstalled SODIMM. To achieve the maximum
memory support, you can populate the system board with up to 4 GB of memory.
DDR2-SDRAM SODIMMs
For proper system operation, the SODIMMs must be:
industry-standard 200-pin
●
●
●
unbuffered PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
1.8 volt DDR2-SDRAM SODIMMs
The DDR2-SDRAM SODIMMs must also:
support CAS latency 5 DDR2 667 MHz (5-5-5 timing) and CAS latency 6 DDR2 800 MHz (6-6-6
timing)
●
contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
●
In addition, the computer supports:
512Mbit and 1Gbit non-ECC memory technologies
single-sided and double-sided SODIMMs
●
●
●
SODIMMs constructed with x8 and x16 devices; SODIMMs constructed with x4 SDRAM are not

Populating SODIMM Sockets
Item
Description
Socket Color

SODIMM1 socket, Channel A
SODIMM3 socket, Channel B
Black
White
NOTE: A SODIMM must occupy the black DIMM1 socket. Otherwise, the
system will display a POST error message indicating that a memory module
must be installed in the black socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the SODIMMs are installed.
The system will operate in single channel mode if the SODIMM sockets are populated in one
channel only.
●
●
●
The system will operate in a higher-performing dual channel mode if the memory capacity of the
SODIMM in Channel A is equal to the memory capacity of the SODIMM in Channel B.
The system will operate in flex mode if the memory capacity of the SODIMM in Channel A is not
equal to the memory capacity of the SODIMM in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
and the remainder is assigned to single channel. If one channel will have more memory than the
other, the larger amount should be assigned to channel A.
In any mode, the maximum operational speed is determined by the slowest SODIMM in the system.
●
Installing SODIMMs
CAUTION: You must disconnect the power cord before adding or removing memory modules.
Regardless of the power-on state, voltage is always supplied to the memory modules as long as the
computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is
present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation
resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. For more information, refer to Electrostatic Discharge Information on page 53.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
3. Locate the memory module sockets on the system board.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.

Cable Management
Always follow good cable management practices when working inside the computer.
Keep cables away from major heat sources like the heatsink.
●
●
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
are not designed to take excessive pressure on them.
Keep cables clear of sliding or moveable parts to prevent their being cut or crimped when the parts
are moved.
●
Do not bend any cable sharply. A sharp bend can break the internal wires.
Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
Never crease a SATA data cable.
●
●
●
●
Do not rely on components like the drive cage, power supply, or computer cover to push cables
down into the chassis. Always position the cables to lay properly by themselves.
When removing the power supply power cables from the P1 or P3 connectors on the system board,
always follow these steps:
1. Squeeze on the top of the retaining latch attached to the cable end of the connector (1).
2. Grasp the cable end of the connector and pull it straight up (2).

B Power Cord Set Requirements
The power supplies on some computers have external power switches. The voltage select switch feature
on the computer permits it to operate from any line voltage between 100-120 or 220-240 volts AC. Power
supplies on those computers that do not have external power switches are equipped with internal
switches that sense the incoming voltage and automatically switch to the proper voltage.
The power cord set received with the computer meets the requirements for use in the country where
you purchased the equipment.
Power cord sets for use in other countries must meet the requirements of the country where you use
the computer.
General Requirements
The requirements listed below are applicable to all countries:
1. The power cord must be approved by an acceptable accredited agency responsible for evaluation
in the country where the power cord set will be installed.
2. The power cord set must have a minimum current capacity of 10A (7A Japan only) and a nominal
voltage rating of 125 or 250 volts AC, as required by each country’s power system.
3. The diameter of the wire must be a minimum of 0.75 mm2 or 18AWG, and the length of the cord
must be between 1.8 m (6 feet) and 3.6 m (12 feet).
The power cord should be routed so that it is not likely to be walked on or pinched by items placed upon
it or against it. Particular attention should be paid to the plug, electrical outlet, and the point where the
cord exits from the product.
WARNING! Do not operate this product with a damaged power cord set. If the power cord set is
damaged in any manner, replace it immediately.
Japanese Power Cord Requirements
For use in Japan, use only the power cord received with this product.
CAUTION: Do not use the power cord received with this product on any other products.

1. The flexible cord must be Type HO5VV-F, 3-conductor, 0.75mm2 conductor size. Power cord set fittings (appliance coupler
and wall plug) must bear the certification mark of the agency responsible for evaluation in the country where it will be used.
2. The flexible cord must be Type SVT or equivalent, No. 18 AWG, 3-conductor. The wall plug must be a two-pole grounding
type with a NEMA 5-15P (15A, 125V) or NEMA 6-15P (15A, 250V) configuration.
3. Appliance coupler, flexible cord, and wall plug must bear a “T” mark and registration number in accordance with the
Japanese Dentori Law. Flexible cord must be Type VCT or VCTF, 3-conductor, 0.75 mm2 conductor size. Wall plug must
be a two-pole grounding type with a Japanese Industrial Standard C8303 (7A, 125V) configuration.

C POST Error Messages
This appendix lists the error codes, error messages, and the various indicator light and audible
sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable
source of the problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count
and non-error text messages. If a POST error occurs, the screen will display the error message. To
manually switch to the POST Messages Enabled mode during POST, press any key (except F10 or
F12). The default mode is POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are
determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory
test. Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish
the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.
NOTE: For more information on Computer Setup, see the Computer Setup (F10) Utility Guide.

This section covers those POST errors that have numeric codes associated with them. The section also
includes some text messages that may be encountered during POST.

CAUTION: Power may still be supplied to the DIMMs when the computer is turned off (depending on
the Management Engine (ME) settings). To avoid damage to the DIMMs or the system board, you must
unplug the computer power cord before attempting to reseat, install, or remove a DIMM module.
For those systems that support ECC memory, HP does not support mixing ECC and non-ECC memory.
Otherwise, the computer will not boot the operating system.
NOTE: The memory count will be affected by configurations with the Management Engine (ME)
enabled. The ME uses 8MB of system memory in single channel mode or 16MB of memory in dual-
channel mode to download, decompress, and execute the ME firmware for Out-of-Band (OOB), third-
party data storage, and other management functions.
