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 Vista or 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.
Installing the Operating System
1
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.
3.
Select the All Programs menu.
4.
Click on the Windows Update link.
In Windows Vista and Windows 7, the Windows Update screen appears. Click view
available updates and make sure all critical updates are selected. Click the Install button and
follow the instructions on the screen.
In Windows XP, you will be directed to the Microsoft Windows Update Web site. If you see
one or more pop-up windows that ask you to install a program from http://www.microsoft.com,
click Yes to install the program. Follow the instructions on the Microsoft Web site to scan for
updates and install critical updates and service packs.
It is recommended that you install all of the critical updates and service packs.
5.
After the updates have been installed, Windows will prompt you to reboot the machine. Be sure to
save any files or documents that you may have open before rebooting. Then select Yes to reboot
the machine.
Installing or Upgrading Device Drivers (Windows
systems)
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 (and firmware), enter the model number of the computer, and press Enter.
Accessing Disk Image (ISO) Files
There are disk image files (ISO files) included on your PC that contain the installation software for
additional software. These CD image files are located in the folder C:\SWSetup\ISOs. Each .iso file
can be burned to CD media to create an installation CD. It is recommended that these disks be created
and the software installed in order to get the most from your PC. The software and image file names
are:

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.

Chapter 3 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.

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.
Electrostatic Discharge Information
35
●
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.
Operating Guidelines
37
●
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.

Memory
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs).
DDR3-SDRAM 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 either 8 GB or 16 GB of memory
configured in a high-performing dual channel mode, depending on model.
Model Number
Maximum Memory
HP Pro 3120
8 GB
HP Pro 3125
16 GB
HP Pro 3130
16 GB
Bezel Blanks
45
For proper system operation, the DDR3-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuffered non-ECC PC3-10600 DDR3-1333 MHz-compliant
●
1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
●
support CAS latency 9 DDR3 1333 MHz (9-9-9 timing)
●
contain the mandatory JEDEC SPD information
In addition, the computer supports:
●
512-Mbit, 1-Gbit, and 2-Gbit 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.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
46
●
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
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 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.

A DIMM must occupy the XMM2 socket.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
94
●
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.
Chapter 6 Removal and Replacement Procedures Small Form Factor (SFF) Chassis
●
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 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.
Installing DIMMs
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. If you see an LED light on the system board, voltage is still present.
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 87).
2.
Remove the access panel (Access Panel on page 88).
3.
Move any cables aside that interfere with removing the memory modules.
Installing Additional Memory
95
4.

socket (2).
Figure 6-6 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module with
the tab on the memory socket.
Populate the DIMM sockets in the following order: DIMM1, DIMM3, DIMM2, then DIMM4.
For maximum performance, populate the sockets so that the memory capacity is spread as equally
as possible between Channel A and Channel B.
5.
Push the module down into the socket, ensuring that the module is fully inserted and properly
seated. Make sure the latches are in the closed position (3).
6.
Repeat steps 4 and 5 to install any additional modules.

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 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.
●
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 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.
2.
Grasp the cable end of the connector and pull it straight up.
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.

11 Password Security and Resetting
CMOS
Resetting the Password Jumper
This computer supports two security password features, which can be established through the Computer
Setup Utilities menu: supervisor password and user password
To disable the password features, or to clear the passwords, complete the following steps:
1.
Shut down the operating system properly, then turn off the computer and any external devices,
and disconnect the power cord from the power outlet.
2.
With the power cord disconnected, press the power button again to drain the system of any
residual power.
WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be
sure to disconnect the power cord from the wall outlet, and allow the internal system components
to cool before touching.
CAUTION: When the computer is plugged in, the power supply always has voltage applied to
the system board even when the unit is turned off. Failure to disconnect the power cord can result
in damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment.
Before beginning these procedures, ensure that you are discharged of static electricity by briefly
touching a grounded metal object.
3.
Remove the computer cover or access panel.
4.
Locate the header and jumper.
NOTE: For assistance locating the password jumper and other system board components, see
the Illustrated Parts & Service Map (IPSM) for that particular system. The IPSM can be downloaded
from http://www.hp.com/support.
5.
On systems with 3-pin jumpers, remove the jumper from pins 1 and 2. Place the jumper on pins 2
and 3.
On systems with 2-pin jumpers, remove the jumper from pins 1 and 2.
184
6.
Replace the computer cover or access panel.
7.
Reconnect the external equipment.
Chapter 11 Password Security and Resetting CMOS
8.
Plug in the computer and turn on power. Allow the operating system to start. This clears the current
passwords and disables the password features.
9.
To establish new passwords, repeat steps 1 through 4, replace the password jumper on pins 1
and 2, then repeat steps 6 through 8. Establish the new passwords in Computer Setup.
Clearing and Resetting the CMOS
The computer’s configuration memory (CMOS) stores information about the computer’s configuration.

Turn off the computer and any external devices, and disconnect the power cord from the power
outlet.
2.
Disconnect the keyboard, monitor, and any other external equipment connected to the computer.
WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be
sure to disconnect the power cord from the wall outlet, and allow the internal system components
to cool before touching.
CAUTION: When the computer is plugged in, the power supply always has voltage applied to
the system board even when the unit is turned off. Failure to disconnect the power cord can result
in damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment.
Before beginning these procedures, ensure that you are discharged of static electricity by briefly
touching a grounded metal object
3.
Remove the computer cover or access panel.
CAUTION: Resetting the CMOS jumper will reset CMOS values to factory defaults. It is
important to back up the computer CMOS settings before resetting them in case they are needed
later. Back up is easily done through Computer Setup.
4.
