2 Installing and Customizing the

Software

If your computer was not shipped with a Microsoft operating system, some portions of this
documentation do not apply. Additional information is available in online help after you install the
operating system.

NOTE: If the computer was shipped with Windows 7 loaded, you will be prompted to register the

computer with HP Total Care before installing the operating system. You will see a brief movie
followed by an online registration form. Fill out the form, click the Begin button, and follow the
instructions on the screen.

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

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

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.

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 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.

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 your computer was not shipped with a Microsoft operating system, some portions of this
documentation do not apply. Additional information is available in online help after you install the
operating system.

Downloading Microsoft Windows Updates

1. To set up your Internet connection, click Start > Internet Explorer and follow the instructions on

the screen.

2. Once an Internet connection has been established, click the Start button.

4 Chapter 2 Installing and Customizing the Software

Computer Setup—Storage

NOTE: Support for specific Computer Setup options may vary depending on the hardware

configuration.

Table 3-3 Computer Setup—Storage

Option Description

Device Configuration Lists all installed BIOS-controlled storage devices.

When a device is selected, detailed information and options are displayed. The following options
may be presented:

CD-ROM: Model, firmware version, serial number.

Hard Disk: Size, model, firmware version, serial number.

● SMART (ATA disks only)

●

Translation mode (ATA disks only)

●

Connector color(ATA disks only)

Lets you select the translation mode to be used for the device. This enables the BIOS to
access disks partitioned and formatted on other systems and may be necessary for users of
older versions of UNIX (e.g., SCO UNIX version 3.2). Options are Automatic, Bit-Shift,
LBA Assisted, User, and Off.

Available only when the drive translation mode is set to User, allows you to specify the
parameters (logical cylinders, heads, and sectors per track) used by the BIOS to translate
disk I/O requests (from the operating system or an application) into terms the hard drive can
accept. Logical cylinders may not exceed 1024. The number of heads may not exceed 256.
The number of sectors per track may not exceed 63.

CAUTION: Ordinarily, the translation mode selected automatically by the BIOS should not

be changed. If the selected translation mode is not compatible with the translation mode that
was active when the disk was partitioned and formatted, the data on the disk will be
inaccessible.

Diskette: Model and firmware version.

NOTE: Displays for USB diskette drives.

Default Values (ATA disks only)

SATA Defaults

See Translation Mode above for details.

Storage Options SATA Emulation

Allows you to choose how the SATA controller and devices are accessed by the operating
system. There are two supported options: IDE and AHCI (default).

IDE - This is the most backwards-compatible setting of the three options. Operating systems
usually do not require additional driver support in IDE mode.

AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take
advantage of more advanced features of the SATA controller.

NOTE: The RAID/AHCI device driver must be installed prior to attempting to boot from a RAID/

AHCI volume. If you attempt to boot from a RAID/AHCI volume without the required device driver
installed, the system will crash (blue screen). RAID volumes may become corrupted if they are
booted to after disabling RAID.

Computer Setup (F10) Utilities 9

Table 3-3 Computer Setup—Storage (continued)

DPS Self-Test Allows you to execute self-tests on ATA hard drives capable of performing the Drive Protection

System (DPS) self-tests.

NOTE: This selection will only appear when at least one drive capable of performing the DPS

self-tests is attached to the system.

Boot Order Allows you to:

● Specify the order in which EFI boot sources (such as a internal hard drive, USB hard drive,

USB optical drive, or internal optical drive) are checked for a bootable operating system
image. Each device on the list may be individually excluded from or included for
consideration as a bootable operating system source.

EFI boot sources always have precedence over legacy boot sources.

●

Specify the order in which legacy boot sources (such as a network interface card, internal
hard drive, USB optical drive, or internal optical drive) are checked for a bootable operating
system image. Each device on the list may be individually excluded from or included for
consideration as a bootable operating system source.

●

Specify the order of attached hard drives. The first hard drive in the order will have priority in
the boot sequence and will be recognized as drive C (if any devices are attached).

NOTE: You can use F5 to disable individual boot items, as well as disable EFI boot and/or

legacy boot.

NOTE: MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating

system has started.

Shortcut to Temporarily Override Boot Order

To boot one time from a device other than the default device specified in Boot Order, restart the
computer and press Esc (to access the boot menu) and then F9 (Boot Order), or only F9 (skipping
the boot menu) when the monitor light turns green. After POST is completed, a list of bootable
devices is displayed. Use the arrow keys to select the preferred bootable device and press Enter.
The computer then boots from the selected non-default device for this one time.

Computer Setup (F10) Utilities 13

Computer Setup—Power

NOTE: Support for specific Computer Setup options may vary depending on the hardware

configuration.

Table 3-5 Computer Setup—Power

Option Description

OS Power
Management (some
models)

● Runtime Power Management— Enable/Disable. Allows certain operating systems to reduce

processor voltage and frequency when the current software load does not require the full
capabilities of the processor. Default is enabled.

● Idle Power Savings—Extended/Normal. Allows certain operating systems to decrease the

processors power consumption when the processor is idle. Default is extended.

●

Unique Sleep State Blink Rates—Enable/Disable. This feature is designed to provide a
visual indication of what sleep state the system is in. Each sleep state has a unique blink
pattern. Default is disabled.

◦

S0 (On) = Solid green LED.

◦ S3 (Stand By)= 3 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds

(green LED) — repeated cycles of 3 blinks and a pause.

◦

S4 (Hibernation)= 4 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds
(green LED) — repeated cycles of 4 blinks and a pause.

◦ S5 (Soft Off) = LED is off.

NOTE: If this feature is disabled, S4 and S5 both have the LED off. S1 (no longer

supported) and S3 use 1 blink per second.

Hardware Power
Management

SATA Power Management – Enables or disables SATA bus and/or device power management.
Default is enabled.

S5 Maximum Power Savings – Turns off power to all nonessential hardware when system is off to
meet EUP Lot 6 requirement of less than 1 Watt power usage. Default is disabled.

S5 Wake on LAN (enable/disable).

●

To disable Wake on LAN during the off state (S5), use the arrow (left and right) keys to
select the Advanced > Device Options menu and set the S5 Wake on LAN feature to
Disable. This obtains the lowest power consumption available on the computer during S5. It
does not affect the ability of the computer to Wake on LAN from suspend or hibernation, but
will prevent it from waking from S5 via the network. It does not affect operation of the
network connection while the computer is on.

●

If a network connection is not required, completely disable the network controller (NIC) by
using the arrow (left and right) keys to select the Security > Device Security menu. Set the
Network Controller option to Device Hidden. This prevents the network controller from being
used by the operating system and reduces the power used by the computer in S5.

Computer Setup—Advanced

NOTE: Support for specific Computer Setup options may vary depending on the hardware

configuration.

Table 3-6 Computer Setup—Advanced (for advanced users)

Option Heading

Power-On Options Allows you to set:

● POST messages (enable/disable). Default is disabled.

●

After Power Loss (off/on/previous state). Default is Power off. Setting this option to:

◦

Power off—causes the computer to remain powered off when power is restored.

◦ Power on—causes the computer to power on automatically as soon as power is

restored.

◦

Previous state—causes the computer to power on automatically as soon as power is
restored, if it was on when power was lost.

NOTE: If you turn off power to the computer using the switch on a power strip, you will not be

able to use the suspend/sleep feature or the Remote Management features.

● POST Delay (in seconds). Enabling this feature will add a user-specified delay to the POST

process. This delay is sometimes needed for hard disks on some PCI cards that spin up very
slowly, so slowly that they are not ready to boot by the time POST is finished. The POST
delay also gives you more time to select F10 to enter Computer (F10) Setup. Default is
None.

BIOS Power-On Allows you to set the computer to turn on automatically at a time you specify.

Bus Options On some models, allows you to enable or disable:

● PCI SERR# Generation. Default is enabled.

●

PCI VGA Palette Snooping, which sets the VGA palette snooping bit in PCI configuration
space; only needed when more than one graphics controller is installed. Default is disabled.

Device Options Allows you to set:

●

Num Lock State at Power-On (off/on). Default is off.

●

Integrated Video (enable/disable). Use this option to disable the integrated video controller
when another video controller is present in the system. Default is enabled.

●

Multi-Processor (enable/disable). Use this option to disable multi-processor support under
the OS. Default is enabled.

●

Hyper-threading (enable/disable) (some models). Use this option to disable processor hyper­threading.

●

NIC Option ROM Download (PXE, iSCSI, disabled). 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. Default is
PXE.

Computer Setup (F10) Utilities 15

Table 3-6 Computer Setup—Advanced (for advanced users) (continued)

VGA Configuration Displayed only if there is an add-in video card in the system. Allows you to specify which VGA

controller will be the “boot” or primary VGA controller.

AMT Configuration
(some models)

Allows you to set:

● AMT (enable/disable). Allows you to enable or disable functions of the embedded

Management Engine (ME) such as Active Management Technology (AMT). If set to disable,
the Management Engine is set to a temporarily disabled state and will not provide functions
beyond necessary system configuration. Default is enabled.

● Unconfigure AMT/ME (enable/disable). Allows you to unconfigure any provisioned

management settings for AMT. The AMT settings are restored to factory defaults. This
feature should be used with caution as AMT will not be able to provide any set AMT
management functions once unconfigured. Default is disabled.

●

Watchdog Timer (enable/disable). Allows you to set amount of time for a operating system
and BIOS watchdog alert to be sent if the timers are not deactivated. BIOS watchdog is
deactivated by BIOS and would indicate that a halt occurred during execution if the alert is
sent to the management console. An operating system alert is deactivated by the operating
system image and would indicate that a hang occurred during its initialization. Default is
enabled.

Recovering the Configuration Settings

This method of recovery requires that you first perform the Save to Removable Media command
with the Computer Setup (F10) Utility before Restore is needed.

NOTE: It is recommended that you save any modified computer configuration settings to a USB

flash media device and save the device for possible future use.

To restore the configuration, insert the USB flash media device with the saved configuration and
perform the Restore from Removable Media command with the Computer Setup (F10) Utility.

5 Serial ATA (SATA) Drive Guidelines

and Features

NOTE: HP only supports the use of SATA hard drives on these models of computer. No Parallel

ATA (PATA) drives are supported.

SATA Hard Drives

Serial ATA Hard Drive Characteristics

Number of pins/conductors in data cable 7/7

Number of pins in power cable 15

Maximum data cable length 39.37 in (100 cm)

Data interface voltage differential 400-700 mV

Drive voltages 3.3 V, 5 V, 12 V

Jumpers for configuring drive N/A

Data transfer rate 3.0 Gb/s

SATA Hard Drive Cables

SATA Data Cable

Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA

1.5 Gb/s drives.

Current HP desktop products ship with SATA 3.0 Gb/s hard drives.

SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and
never bend it tighter than a 30 mm (1.18 in) radius.

The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.

36 Chapter 5 Serial ATA (SATA) Drive Guidelines and Features

SMART ATA 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.

6 Routine Care, and Disassembly

Preparation

This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.

CAUTION: When the computer is plugged into an AC power source, voltage is always applied to

the system board. You must disconnect the power cord from the power source before opening the
computer to prevent system board or component damage.

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.

●

Static electricity increases as humidity decreases.

Preventing Electrostatic Damage to Equipment

Many electronic components are sensitive to ESD. Circuitry design and structure determine the
degree of sensitivity. The following packaging and grounding precautions are necessary to prevent
damage to electric components and accessories.

●

To avoid hand contact, transport products in static-safe containers such as tubes, bags, or
boxes.

●

Protect all electrostatic parts and assemblies with conductive or approved containers or
packaging.

●

Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.

●

Place items on a grounded surface before removing them from their container.

●

Always be properly grounded when touching a sensitive component or assembly.

●

Avoid contact with pins, leads, or circuitry.

●

Place reusable electrostatic-sensitive parts from assemblies in protective packaging or
conductive foam.

Personal Grounding Methods and Equipment

Use the following equipment to prevent static electricity damage to equipment:

● Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground

cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord
must be connected and fit snugly into the banana plug connector on the grounding mat or
workstation.

●

Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible
with most types of shoes or boots. On conductive floors or dissipative floor mats, use them on
both feet with a maximum of one-megohm ± 10% resistance between the operator and ground.

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.

Operating Guidelines 41

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

work area to prevent damage.

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

NOTE: A DIMM must occupy the XMM1 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 1-GB DIMMs and Channel B is populated with one 2-GB 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

54 Chapter 7 Removal and Replacement Procedures Microtower (MT) Chassis

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 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as
dual channel and 1-GB will run as single channel.

●

In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.

Removing Memory Modules

CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power

to drain 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.

When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

1. Prepare the computer for disassembly (Preparation for Disassembly on page 46).

2. Remove the access panel (

Cable Management

Always follow good cable management practices when working inside the computer.

●

Keep cables away from major heat sources like the heat sink.

●

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.

●

Some flat ribbon cables come prefolded. Never change the folds on these cables.

●

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 cable 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.

Installing Additional Drives

When installing drives, follow these guidelines:

● The primary Serial ATA (SATA) hard drive must be connected to the dark blue primary SATA

connector on the system board labeled SATA0.

● Connect an optical drive to the light blue SATA connector on the system board labeled SATA2.

● The power cables for the SATA drives connect directly to the power supply. The primary hard

drive connects to the power connector labeled P4. the primary optical drive connects to the
power connector labeled P3.

●

The system does not support Parallel ATA (PATA) optical drives or PATA hard drives.

CAUTION: To prevent loss of work and damage to the computer or drive:

If you are inserting or removing a drive, shut down the operating system properly, turn off the
computer, and unplug the power cord. Do not remove a 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 to

Electrostatic Discharge Information on page 38.

Handle a drive carefully; do not drop it.

Do not use excessive force when inserting a drive.

Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields
such as monitors or speakers.

If a drive must be mailed, place the drive in a bubble-pack mailer or other protective packaging and
label the package “Fragile: Handle With Care.”

CAUTION: Heat sink retaining screws should be tightened in diagonally opposite pairs (as in an X)

to evenly seat the heat sink to the processor. This is especially important as the pins on the socket
are very fragile and any damage to them may require replacing the system board.

When reinstalling an existing heat sink, make sure that its bottom has been cleaned with an alcohol
wipe and fresh thermal grease has been applied to the top of the processor. New heat sinks come
from the factory with fresh thermal grease already applied.
