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.

Computer Setup—Advanced
NOTE: Support for specific Computer Setup options may vary depending on the hardware
configuration.
Table 3-5 Computer Setup—Advanced
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 enable.
●
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 disable.
Device Options Allows you to set:
● Num Lock State at Power-On (off/on). Default is off.
●
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.
●
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.
●
NIC PXE 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.

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

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.
18 Chapter 4 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.

5 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.

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.

Grounding the Work Area
To prevent static damage at the work area, use the following precautions:
● Cover the work surface with approved static-dissipative material. Provide a wrist strap connected
to the work surface and properly grounded tools and equipment.
● Use static-dissipative mats, foot straps, or air ionizers to give added protection.
● Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate.
Handle them only at static-free work areas.
● Turn off power and input signals before inserting and removing connectors or test equipment.
● Use fixtures made of static-safe materials when fixtures must directly contact dissipative
surfaces.
● Keep work area free of nonconductive materials such as ordinary plastic assembly aids and
Styrofoam.
●
Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.
