Installing the Operating System

Ä CAUTION: Do not add optional hardware or third-party devices to your computer until the operating system is successfully installed. Doing so may cause errors and may prevent the operating system from installing properly.

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 might damage the software that runs the computer or prevent its proper installation.

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.

The first time the computer is turned on, the operating system is automatically installed. This takes approximately 10 minutes, depending on the operating system being installed. Carefully read and follow the instructions that appear on the screen to complete the installation.

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 the computer was not shipped with a Microsoft operating system, some portions of this documentation do not apply. For complete operating system installation and configuring instructions, refer to the operating system documentation. Additional information is available in online help.

Microsoft security updates are available on the Microsoft Web site.

1.1 Installing or Upgrading Device Drivers

To install optional hardware devices after the operating system installation is complete, the drivers for each of the devices must also be installed.

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 www.hp.com/support

. Select the appropriate country and language then, select Download

drivers and software, enter the model number of the computer, and press

Enter

.

You can also obtain the latest support software on CDs. The following Web site provides information on how to purchase a support software CD subscription: http://h18000.www1.hp.com/support/files/desktops/us/purchase.html.

If the computer has a writable optical drive, install the appropriate application to be able to write to the drive.

Service Reference Guide, dc5700 437804-001 1–1

Installing the Operating System

1.2 Transferring Files and Settings

Use the Microsoft Windows XP Files and Settings Transfer Wizard to move files and settings from an old computer to a new one. Click Start > All Programs > Accessories > System Tools

> Files and Settings Transfer Wizard. Follow the wizard to transfer the files and settings to the new computer.

1.3 Creating a Disc Recovery Set

Ä CAUTION: HP no longer ships the Restore Plus! CD with PCs. Instead, HP Backup and Recovery

Manager is pre-loaded on each system. HP recommends the creation of a recovery CD as soon as the computer has been set up. Creating the Restore Plus! CD set is important in the event that you ever need to restore the system hard drive to its factory installed state.

HP Backup and Recovery Manager can create the Restore Plus CD set, This set includes the

Restore Plus CD, the Operating System CD, and any Supplemental Software CDs.

Ä CAUTION: The Restore Plus CD set will not include any system settings or user data created after the initial system setup.

T o create the Restore Plus CD 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 factory software recovery CDs or DVDs to recover the system.

3. Follow the instructions in the wizard.

The HP Backup and Recovery Manager can be used to back up data and system files to the hard drive, to network drives, or to removable media, such as CDs, DVDs, or flash media. If data or system files are lost, deleted, or corrupted, Backup and Recovery Manager allows you to retrieve data or restore the last good system image.

Ä

CAUTION: HP recommends that a backup schedule be created immediately to ensure continued system and data protection. Automatic backups can be scheduled using the HP Backup and Recovery Wizard.

Recovery Points, Entire Drive Backups, and File Backups can be automatically backed up without user intervention. HP recommends scheduling Recovery Points Backups to provide the most comprehensive coverage.

If HP Backup and Recovery Manager is preinstalled, the Restore Plus CD set and the initial recovery point may be saved to disc as often as necessary, but only a single copy of the Microsoft

Windows CD can be created, due to licensing constraints.

You can access a user manual at Start > HP Backup and Recovery > HP Backup and

Recovery Manager Manual.

If Create factory software recovery CDs or DVDs to recover the system is unavailable on the system, the HP Restore Plus CD set can be obtained through product support on http://welcome/country/us/en/contact_us.html.

3.3.1 HP Client Management Interface

HP Client Management Interface (HP CMI) provides an interface to simplify the integration of 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.

Some scripts are needed to access the HP CMI interface.

Service Reference Guide, dc5700 437804-001 3–3

Desktop Management

When HP Client Management Interface is used in conjunction with system management software, it can:

Request in-depth client inventory information - Capture detailed information about the processors, hard drives, memory, BIOS, drivers, and 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 the system management console of any or all of the client systems without having to visit each machine.

3.3.2 HP System Software Manager

HP System Software Manager (SSM) is a free utility that automates remote deployment of device drivers and BIOS updates for 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

Microsoft Systems Management Server (SMS). Using SSM, you can distribute customer-created or third-party updates that have been packaged in the SSM-format.

SSM may be downloaded at no charge by visiting www.hp.com/go/ssm

.

3.3.3 HP Client Manager

3.3.12 Retired Solutions

Two software packages, Altiris Local Recovery, and Dantz Retrospect, will no longer be shipping on HP business desktops, notebooks, or workstations. Starting with new business desktops, notebooks, and workstations released in 2006, all will ship with HP Backup and

Recovery Manager.

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 support page: http:\\h18000.www1.hp.com/support/files

.

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 http://www.hp.com/go/ssm

.

3.4.1 Remote ROM Flash

Remote ROM Flash allows the system administrator to safely upgrade the ROM 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.

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 or System

Software Manager at http://h18000.www1.hp.com/im/prodinfo.html

3.4.2 HPQFlash

The HPQFlash utility is used to locally update or restore the system BIOS on individual PCs through a Windows operating system.

For more information on HPQFlash, visit http://www.hp.com/support/files

and enter the product name/number of the computer when prompted.

3.4.3 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.

To recover the system after it enters Boot Block Emergency Recovery Mode, complete the following steps:

1. Turn off the power.

2. Insert a diskette, 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 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.

3.5.4 DriveLock

DriveLock is an industry-standard security feature that prevents unauthorized access to the data on ATA hard drives. 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 and the loss of the data stored on it is inconsequential when compared with the damage that could result from unauthorized access to its contents. In order 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.

Desktop Management

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.

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.

3.5.5 Cable Lock Provision

The rear panel of the computer accommodates a cable lock so that the computer can be physically secured to a work area. For illustrated instructions, please see the Removal and

3.6 Fault Notification and Recovery

Fault Notification and Recovery features combine innovative hardware and software technology to prevent the loss of critical data and minimize unplanned downtime.

If the computer is connected to a network managed by HP Client Manager, the computer sends a fault notice to the network management application. With HP Client Manager, you can also remotely schedule diagnostics to automatically run on all managed PCs and create a summary report of failed tests.

3.6.1 Drive Protection System

The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in some HP computers. DPS is designed to help diagnose problems that might result in unwarranted hard drive replacement.

When HP computers are built, each installed hard drive is tested using DPS, and a permanent record of key information is written onto the drive. Each time DPS is run, test results are written to the hard drive. Your service provider can use this information to help diagnose conditions that caused you to run the DPS software. Refer to the Troubleshooting Guide for instructions on using

DPS.

3.6.2 Surge-Tolerant Power Supply

An integrated surge-tolerant power supply provides greater reliability when the computer is hit with an unpredictable power surge. This power supply is rated to withstand a power surge of up to 2000 volts without incurring any system downtime or data loss.

3.6.3 Thermal Sensor

The thermal sensor is a hardware and software feature that tracks the internal temperature of the computer. This feature displays a warning message when the normal range is exceeded, which gives you time to take action before internal components are damaged or data is lost.

4.3 PATA Device Information

No PATA drives are supported on these models.

4.4 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.

4.5 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.

Identifying the Chassis, Routine Care, and Disassembly Preparation

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.

5.2.1 Generating Static

The following table shows that:

Different activities generate different amounts of static electricity.

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.

If operating in a dusty environment, periodic cleaning of heatsink and fans is recommended to prevent overheating.

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.

When cleaning debris from under the keys, review all rules in Section 5.4.1 before following these procedures:

Ä CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.

Visible debris underneath or between the keys may be removed by vacuuming or shaking.

Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys.

If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets.

Ä CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly.

5–6 437804-001 Service Reference Guide, dc5700

Identifying the Chassis, Routine Care, and Disassembly Preparation

Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.

5.4.4 Cleaning the Monitor

Wipe the monitor screen with a clean cloth moistened with water or with a towelette designed for cleaning monitors. Do not use sprays or aerosols directly on the screen; the liquid may seep into the housing and damage a component. Never use solvents or flammable liquids on the monitor.

To clean the monitor body follow the procedures in Section 5.4.2

Identifying the Chassis, Routine Care, and Disassembly Preparation

5.5.3 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.

Metric screws have a black finish.

U.S. screws have a silver finish and are used on hard drives only.

As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage.

5.5.4 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.

Ä 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.

5.5.5 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 damage, refer to Section 5.2, “Electrostatic Discharge Information.”

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.

6.6 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.

Ä 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.

Removal and Replacement Procedures— Small Form Factor (SFF) Chassis

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 access panel 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.

Ä 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.

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 mm

2

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.

Å

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.

Troubleshooting Without Diagnostics

Preliminary Checklist

This section describes some simple, preliminary tests and guidelines for troubleshooting the computer without using the diagnostics.

Check that the computer and monitor are plugged into a working electrical outlet.

Check to see that the voltage select switch (some models) is set to the appropriate voltage for your region (115V or 230V).

Check to see that the computer turned on and the green power light is on.

Check to see that the monitor turned on and the green power light is on.

Check the Power LED on the front of the computer to see if it is flashing red. The flashing lights are error codes that will help you diagnose the problem.

Turn up the monitor brightness and contrast controls if the monitor is dim.

Press and hold any key. If the system beeps, then the keyboard is operating correctly.

Check all cables for loose or incorrect connections.

Wake the computer by pressing any key on the keyboard or pressing the power button. If the system remains in suspend mode, shut down the computer by pressing and holding the power button for at least four seconds then press the power button again to restart the computer. If the system will not shut down, unplug the power cord, wait a few seconds, then plug it in again. The computer will restart if automatic start on power loss is set in Computer Setup. If it does not restart, press the power button to start the computer.

Reconfigure the computer after installing a non–plug and play expansion board or other option.

Be sure that all of the needed device drivers have been installed. For example, if you are using a printer, you need a driver for that model printer.

Remove all bootable media (diskette, CD, or USB device) from the system before turning it on.

If you have installed an operating system other than the factory-installed operating system, check to be sure that it is supported on the system.

If the system has multiple video sources (embedded, PCI, or PCI-Express adapters) installed

(embedded video on some models only) and a single monitor, the monitor must be plugged into the monitor connector on the source selected as the primary VGA adapter. During boot, the other monitor connectors are disabled and if the monitor is connected into these ports, the monitor will not function. You can select which source will be the default VGA source in

Computer Setup.

The media card is a read-only memory

(ROM) card.

Unable to access data on the media card after inserting it into a slot.

Do not know how to remove a media card correctly.

The media card is not inserted properly, is inserted in the wrong slot, or is not supported.

The computer’s software is used to safely eject the card.

Check the manufacturer’s documentation included with your card to see if it writable. Refer to the previous section for a list of compatible cards.

Ensure that the card is inserted properly with the gold contact on the correct side. The green LED will light if inserted properly.

Open My Computer, right-click on the corresponding drive icon, and select Eject. Then pull the card out of the slot.

Never remove the card when the green LED is flashing.

Wait a few seconds so that the operating system can recognize the reader and the available ports, and then recognize whatever media is inserted in the reader.

After installing the media card reader and booting to

Windows, the reader and the inserted cards are not recognized by the computer.

After inserting a media card in the reader, the computer attempts to boot from the media card.

Computer will not boot from a USB removable drive or media that is inserted in the USB port on the media card reader.

After installing the media card reader, the front USB ports on the computer do not work.

The operating system needs time to recognize the device if the reader was just installed into the computer and you are turning the PC on for the first time.

The inserted media card has boot capability.

The media card reader is connected to the computer via the PCI card, which is not supported on the HP

Desktop BIOS.

The USB cable for the front USB ports was disconnected so that the system board connector could be used for the reader.

If you do not want to boot from the media card, remove it during boot or do not select the option to boot from the inserted media card during the boot process.

The bootable USB device will have boot support if you connect the media card reader to an available

USB connector on the computer’s system board. If no connector is available, plug the bootable device into a different USB port on the computer.

Reconnect the cable for the front

USB ports. Install the PCI card and connect the media reader to the

USB connector on the PCI card.

See the documentation that came with the optional device.

See the documentation that came with the DVD drive.

Decoder software is not installed.

Damaged media.

Movie rating locked out by parental lock.

Media installed upside down.

Disc not properly seated in the drive.

Install decoder software.

Replace media.

Use DVD software to remove parental lock.

Reinstall media.

Wrong or poor quality media type.

1. Turn off the computer and insert a thin metal rod into the emergency eject hole and push firmly.

2. Slowly pull the tray out from the drive until the tray is fully extended, then remove the disc.

Re-insert the Media with the label facing up.

Media has been inserted upside down.

The DVD-ROM drive takes longer to start because it has to determine the type of media played, such as audio or video.

Wait at least 30 seconds to let the

DVD-ROM drive determine the type of media being played. If the disc still does not start, read the other solutions listed for this topic.

CD or DVD disc is dirty. Clean CD or DVD with a CD cleaning kit.

Windows does not detect the CD-ROM or

DVD-ROM drive.

1. Use Device Manager to remove or uninstall the device in question.

2. Restart the computer and let

Windows detect the device.

1. Try using a slower recording speed.

2. Verify that you are using the correct media for the drive.

3. Try a different brand of media.

Quality varies widely between manufacturers.

Memory

The dc5700 series computers with Intel-based processors come with double data rate 2 synchronous dynamic random access memory (DDR2-SDRAM) dual inline memory modules

(DIMMs).

Ä

CAUTION:

DDR and DDR2 memory modules are not interchangeable.

DDR2-SDRAM DIMMs

The memory sockets on the system board can be populated with up to four industry-standard

DIMMs. These memory module sockets are populated with at least one preinstalled memory module. To achieve the maximum memory support, you can populate the system board with up to 8GB of memory configured in a high-performing dual channel mode.

For proper system operation, the DDR2-SDRAM DIMMs must be:

■ industry-standard 240-pin unbuffered PC2-4300 533 MHz-compliant, PC2-5300 667 MHz-compliant, or PC2-6400

800 MHz-compliant

1.8volt DDR2-SDRAM DIMMs

The DDR2-SDRAM DIMMs must also:

■ support CAS latency 4 (DDR2/533 MHz and DDR2/667 MHz) and CAS latency 5

(DDR2/667 MHz and DDR2/800 MHz)

■ contain the mandatory JEDEC SPD information

In addition, the computer supports:

256Mbit, 512Mbit, AND 1 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

The system will not start if you install unsupported DIMMs.

DIMM Sockets

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.

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 256MB DIMMs and Channel B is populated with one

512MB 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. For example, if you are populating the sockets with one 1GB DIMM, two

512MB DIMMs, and one 256MB DIMM, one channel should be populated with the 1GB

DIMM and one 256MB DIMM and the other channel should be populated with the two

512MB DIMMs. With this configuration, 2 GB will run as dual channel and 256 MB will run as single channel.

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