2 Activating and Customizing the
Software
NOTE: This chapter provides information for both Windows 7 and Windows 8.

Activating and customizing the software in Windows 7

If your computer was not shipped with a Windows® operating system, some portions of this documentation do not apply. Additional information is available in online help after you activate the operating system.
CAUTION: Do not add optional hardware or third-party devices to the computer until the operating
system is successfully activated. 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.

Activating the Windows operating system

The first time you turn on the computer, the operating system is set up and activated automatically. This process takes about 5 to 10 minutes. Carefully read and follow the instructions on the screen to complete the activation.
We recommend that you register your computer with HP during operating system setup so you can receive important software updates, facilitate support questions, and sign up for special offers.
CAUTION: After the activation process has begun, DO NOT TURN OFF THE COMPUTER UNTIL THE
PROCESS IS COMPLETE. Turning off the computer during the activation 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
activation process could take up to 60 minutes.

Downloading Windows 7 updates

Microsoft may release updates to the operating system. To help keep the computer running optimally, HP recommends checking for the latest updates during the initial installation and periodically throughout the life of the computer.
1. To set up your Internet connection, click Start > Internet Explorer and follow the instructions
on the screen.
2. After an Internet connection has been established, click the Start > All Programs > Windows
Update.
3. Run Windows Update monthly thereafter.

Installing or upgrading device drivers

When installing optional hardware devices after the operating system installation is complete, you must also install the drivers for each of the devices.
In Windows 7, 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.

Customizing the monitor display

If you wish, you can select or change the monitor refresh rates, screen resolution, color settings, font sizes, and power management settings.
For more information, refer to the online documentation provided with the graphics controller utility or the documentation that came with your monitor.
Right-click on the Windows desktop, then click Personalize to change display settings.

Activating and customizing the software in Windows 8

Additional information is available in online help after you activate the operating system.
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.

Activating the Windows Operating System

The first time you turn on the computer, the operating system is set up and activated automatically. This process takes about 5 to 10 minutes. Carefully read and follow the instructions on the screen to complete the activation.

guidelines, 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.

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.
38 Chapter 4 Routine care, SATA drive guidelines, and disassembly preparation
Page 51
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.

Screws

The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of different lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations.
CAUTION: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard
drives only.
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.

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.

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.

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.
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.

Memory

Description Spare part number
8-GB, PC3-12800 689375-001
4-GB, PC3-12800 671613-001
2-GB, PC3-12800 671612-001
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3­SDRAM) 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 32-GB of memory configured in a high­performing dual channel mode.

DDR3-SDRAM DIMMs

For proper system operation, the DDR3-SDRAM DIMMs must be:
industry-standard 240-pin
unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
1.35 volt or 1.5 volt DDR3/DDR3L-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
support CAS latency 11 DDR3 1600 MHz (11-11-11 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.

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 B. Sockets DIMM3 and DIMM4 operate in memory channel A.
50 Chapter 5 Removal and replacement procedures: Tower (TWR)
Page 63
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior
graphics performance.
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 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.
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 44).
2. Remove the access panel (
Access panel on page 45)
Memory
51
Page 64
3. Open both latches of the memory module socket (1), and insert the memory module into the
socket (2).
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 black DIMM sockets before the white DIMM sockets.
For maximum performance, populate the sockets so that the memory capacity is spread as equally as possible between Channel A and Channel B. Refer to
Populating DIMM sockets on page 50 for
more information.
4. 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).
5. Repeat steps 3 and 4 to install any additional modules.
The computer should automatically recognize the additional memory the next time you turn on the computer.
