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.
SATA Hard Drives 7
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.

4 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.

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.

Electrostatic Discharge Information 11
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 removed.
● Do not place computers so near each other that they are subject to each other’s re-circulated or preheated air.
● 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.

computer.
12 Chapter 4 Routine Care, and Disassembly Preparation
To clean the computer case, follow the procedures described below:
● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with clear water.
● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will evaporate quickly and not leave a residue.
● After cleaning, always wipe the unit with a clean, lint-free cloth.
● Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and limit the airflow.
Cleaning the Keyboard
Follow all safety precautions in
General Cleaning Safety Precautions on page 12
before cleaning the keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in
before following these procedures:
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.
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.
● 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.
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
Cleaning the Computer Case on page 12 .
Routine Care 13
Cleaning the Mouse
Before cleaning the mouse, ensure that the power to the computer is turned off.
● Clean the mouse ball by first removing the retaining plate and the ball from the housing. Pull out any debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly.
● To clean the mouse body, follow the procedures in
Cleaning the Computer Case on page 12 .
Service Considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and assembly of the computer.

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: 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.
14 Chapter 4 Routine Care, and Disassembly Preparation
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 Electrostatic Discharge Information on page 9

Storage Options eSATA Port
Allows you to set a SATA port as an eSATA port for use with an external drive. Default is enabled.
This setting affects only the port with the black connector, labeled as eSATA on the system board.
This port should have the eSATA back panel connector attached to use eSATA drives. For more information, see the eSATA white paper at www.hp.com
.
SATA Emulation
Allows you to choose how the SATA controller and devices are accessed by the operating system. There are three supported options: IDE, RAID, and AHCI (default).
CAUTION: SATA emulation changes may prevent access to existing hard drive data and degrade or corrupt established volumes.
IDE - This is the most backwards-compatible setting of the three options. Operating systems usually do not require additional driver support in IDE mode.
RAID - Allows DOS and boot access to RAID volumes. Use this mode with the RAID device driver loaded in the operating system to take advantage of RAID features.
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.
Removable Media Boot
Enables/disables ability to boot the system from removable media. Default is enabled.
Max eSATA Speed
Allows you to choose 1.5 Gbps or 3.0 Gpbs as the maximum eSATA speed. By default, the speed is limited to 1.5 Gbps for maximum reliability.

Master Boot Record
Security
Allows you to disable any PCI or PCI Express slot. Default is enabled.
Enables/disables the computer’s ability to boot from an operating system installed on a network server. (Feature available on NIC models only; the network controller must be either a PCI expansion card or embedded on the system board.) Default is enabled.
Allows you to set:
● Asset tag (18-byte identifier), a property identification number assigned by the company to the computer.
● Ownership tag (80-byte identifier) displayed during POST.
● Universal Unique Identifier (UUID) number. The UUID can only be updated if the current chassis serial number is invalid. (These ID numbers are normally set in the factory and are used to uniquely identify the system.)
● Keyboard locale setting for System ID entry.
Enables/disables Master Boot Record (MBR) security.
The MBR contains information needed to successfully boot from a disk and to access the data stored on the disk. Master Boot Record Security may prevent unintentional or malicious changes to the MBR, such as those caused by some viruses or by the incorrect use of certain disk utilities.
It also allows you to recover the "last known good" MBR, should changes to the MBR be detected when the system is restarted.
When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the current bootable disk while in MS-DOS or Windows Safe Mode.
NOTE: Most operating systems control access to the MBR of the current bootable disk; the
BIOS cannot prevent changes that may occur while the operating system is running.
Restores the backup Master Boot Record to the current bootable disk. Default is disabled.
Only appears if all of the following conditions are true:
● MBR security is enabled
● A backup copy of the MBR has been previously saved
● The current bootable disk is the same disk from which the backup copy was saved
CAUTION: Restoring a previously saved MBR after a disk utility or operating system has modified the MBR, may cause the data on the disk to become inaccessible. Only restore a previously saved MBR if you are confident that the current bootable disk's MBR has been corrupted or infected with a virus.

Heading
Allows you to set:
● POST mode (QuickBoot, Clear Memory, FullBoot, or FullBoot Every x Days).
◦ QuickBoot (default) = Do not clear memory or perform a memory test.
◦
◦ FullBoot = Memory test (count) on cold boot. Clears memory on all boots.
Clear Memory = No memory count on cold boot. Clears memory on all boots.
◦ FullBoot Every x Days = Memory count on 1st cold boot on or after the xth day. No more memory counts until 1st cold boot on or after x days. Clears memory on all boots.
● POST messages (enable/disable). Enabling this feature will cause the system to display
POST error messages, which are error messages displayed on the monitor during the Power
On Self Test if the BIOS encounters some kind of problem while starting the PC. A POST error message will only display on screen if the computer is capable of booting this far. If the
POST detects an error before this point, a beep code is generated instead. Default is disabled.
● Press the ESC key for Startup Menu (Enable/Disable). This feature controls the display of the text “Press the ESC key for Startup Menu” during POST. This text does not display on
Windows 8 systems with Fast Boot support. Other text also will not display (for example,
Ownership Tag). Default is enabled.
● Option ROM Prompt (enable/disable). Enabling this feature will cause the system to display a message before loading option ROMs. Default is enabled.
● 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.
● Remote Wakeup Boot Source (remote server/local hard drive). Default is Local hard drive.
● Factory Recovery Boot Support (Enable/Disable). Provides the ability for the BIOS to redirect the boot to the recovery partition on the user hard drive, if present. Some versions of the recovery software honor the F11 key press even when this feature is disabled by the BIOS.
Default is disabled.
● Bypass F1 Prompt on Configuration Changes (Enable/Disable). Allows you to set the computer not to confirm when changes were made. Default is disabled.

Allows you to set resources for or disable Legacy devices.
Select the Legacy device's IRQ, DMA, and I/O Range. The settings may not take effect for all operating systems. To hide a device from the operating system, see Security > Device Security.
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.
Allows you to set:
● Printer mode (Bi-Directional, EPP + ECP, Output Only). ECP = Enhanced Capabilities Port,
EPP = Enhanced Parallel Port. Default is EPP+ECP.
● 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.
● Integrated Graphics (Auto/Disable/Force) Use this option to manage integrated (UMA) graphics memory allocation. The value you choose is allocated permanently to graphics and is unavailable to the operating system. For example, if you set this value to 512M on a system with 2 GB of RAM, the system always allocates 512 MB for graphics and the other
1.5 GB for use by the BIOS and operating system. Default is Auto which sets memory allocation to 512 MB.
If you select Force, the UMA Frame Buffer Size option displays, which lets you set the UMA memory size allocation between 32 MB and 1 GB.
● Internal Speaker (does not affect external speakers). 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.
● SATA RAID Option ROM Download (enable/disable). The BIOS contains an embedded
SATA RAID option ROM for RAID support. This can be temporarily disabled to save DCH space. Note that with the option ROM disabled, users will be unable to boot to hard drives in the system while running in RAID mode. Default is disabled.
● Multi-Processor (enable/disable). Use this option to disable multi-processor support under the OS. Default is enabled.
● Hyper threading (enable/disable). Use this option to disable processor hyper-threading.
● Turbo Mode (enable/disable). Allows you to enable and disable the Intel Turbo Mode feature, which allows one core of the system to run at a higher than standard frequency and power if other cores are idle. Default is enabled.

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.
● Hide Unconfigure ME Confirmation Prompt (enable/disable). Allows you to set the system to not display the confirmation to unconfigure ME.
● 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. (See
Computer Setup—File on page 18
in the Computer Setup—File table.)
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. (See
Computer Setup—File on page 18 in the Computer Setup—File table.)

122 Appendix A Troubleshooting Without Diagnostics
B HP PC Hardware Diagnostics
If HP Support Assistant is unable to detect a problem, try the UEFI-based hardware diagnostic solution that HP includes on all products. You can use this tool even if the computer will not boot to the operating system. This tool also works with components not diagnosed in HPSA.
Why run HP PC Hardware Diagnostics
The HP PC Hardware Diagnostic tools simplify the process of diagnosing hardware issues and expedite the support process when issues are found. The tools save time by pinpointing the component that needs to be replaced.
● Isolate true hardware failures: The diagnostics run outside of the operating system so they effectively isolate hardware failures from issues that may be caused by the operating system or other software components.
● Failure ID: When a failure is detected that requires hardware replacement, a 24-digit Failure ID is generated. This ID can then be provided to the call agent, who will either schedule support or provide replacement parts.
How to access and run HP PC Hardware Diagnostics
You can run the diagnostics from one of three places, depending on your preference and the health of the computer.
1.
Turn on the computer and press Esc repeatedly until the BIOS Boot Menu appears.
2.

From the Start screen, type h, and then select Help and Support.
Backing up your information
Recovery after a system failure is as good as your most recent backup. You should create system repair media and your initial backup immediately after initial system setup. As you add new software and data files, you should continue to back up your system on a regular basis to maintain a reasonably current backup. The system repair media is used to start up (boot) the computer and repair the operating system in case of system instability or failure. Your initial and subsequent backups allow you to restore your data and settings if a failure occurs.
Type backup on the Start screen, click Settings, and then select Save backup copies of your files
with File History.
You can back up your information to an optional external hard drive, or a network drive.
Note the following when backing up:
● Store personal files in the Documents library, and back it up regularly.
● Back up templates that are stored in their associated programs.
● Save customized settings that appear in a window, toolbar, or menu bar by taking a screen shot of your settings. The screen shot can be a time-saver if you have to reset your preferences.
To create a backup using Backup and Restore:
NOTE: Be sure that the computer is connected to AC power before you start the backup process.

D POST Error Messages
This appendix lists the error codes, error messages, and the various indicator light and audible sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable source of the problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count and non-error text messages. If a POST error occurs, the screen will display the error message. To manually switch to the POST Messages Enabled mode during POST, press any key (except F10 ,
F11 , or F12 ). The default mode is POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory test. Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.

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 1.0 m (3.3 ft) and no more than 2.0 m (6.5 ft).
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.
