Table 3-3 Computer Setup—Storage

Option Description

Device Configuration Lists all installed BIOS-controlled storage devices.

When a device is selected, detailed information and options are displayed. The following options
may be presented:

●

Hard Disk: Size, model, firmware version, serial number, connector color.

Translation mode (ATA disks only)

Lets you select the translation mode to be used for the device. This enables the BIOS to
access disks partitioned and formatted on other systems and may be necessary for users of
older versions of UNIX (e.g., SCO UNIX version 3.2). Options are Automatic, Bit-Shift,
LBA Assisted, User, and Off.

Available only when the drive translation mode is set to User, allows you to specify the
parameters (logical cylinders, heads, and sectors per track) used by the BIOS to translate
disk I/O requests (from the operating system or an application) into terms the hard drive can
accept. Logical cylinders may not exceed 1024. The number of heads may not exceed 256.
The number of sectors per track may not exceed 63.

CAUTION: Ordinarily, the translation mode selected automatically by the BIOS should not

be changed. If the selected translation mode is not compatible with the translation mode that
was active when the disk was partitioned and formatted, the data on the disk will be
inaccessible.

●

CD-ROM: Model, firmware version, serial number, connector color (not included for USB CD­ROM).

●

SSD Life Used

NOTE: Displays for solid-state drives.

● SMART (ATA disks only)

●

Diskette: Model and firmware version.

NOTE: Displays for USB diskette drives.

● Default Values (ATA disks only)

See Translation Mode above for details.

SATA Defaults

Computer Setup (F10) Utilities 11

Table 3-3 Computer Setup—Storage (continued)

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.

Master Boot Record
Security

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.

Power-On Options 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

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

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 10 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

5 Serial ATA (SATA) Drive Guidelines

and Features

NOTE: HP only supports the use of SATA hard drives on these models of computer. No Parallel

ATA (PATA) drives are supported.

SATA Hard Drives

Serial ATA Hard Drive Characteristics

Number of pins/conductors in data cable 7/7

Number of pins in power cable 15

Maximum data cable length 39.37 in (100 cm)

Data interface voltage differential 400-700 mV

Drive voltages 3.3 V, 5 V, 12 V

Data transfer rate 3.0 Gb/s

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.

SATA Hard Drives 39

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.

6 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.

Electrostatic Discharge Information 43

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.

●

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.

Routine Care

General Cleaning Safety Precautions

1. Never use solvents or flammable solutions to clean the computer.

2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and

then use the cloth on the component.

3. Always unplug the computer when cleaning with liquids or damp cloths.

4. Always unplug the computer before cleaning the keyboard, mouse, or air vents.

5. Disconnect the keyboard before cleaning it.

6. Wear safety glasses equipped with side shields when cleaning the keyboard.

computer.

44 Chapter 6 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 44 before cleaning the
keyboard.

To clean the tops of the keys or the keyboard body, follow the procedures described in

Cleaning the

Computer Case on page 44.

When cleaning debris from under the keys, review all rules in

General Cleaning Safety Precautions

on page 44 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 44.

Routine Care 45

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 44.

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: 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.

46 Chapter 6 Routine Care and Disassembly Preparation

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.

●

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

●

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

Memory 55

NOTE: The system will not operate properly if you install unsupported DIMMs.

Populating DIMM Sockets

Populate the DIMM sockets in the following order: XMM1, XMM3

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. If Channel A is populated with
one 1-GB DIMM 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. If you are populating the sockets with one 2-GB DIMM, and one 1-GB DIMM,
Channel A should be populated with the 2-GB DIMM, and Channel B should be populated with
the 1-GB DIMM. With this configuration, 2 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.

The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.

Removing Memory Modules

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 48).

2. Remove the access panel (

Access Panel on page 49).

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.

●

Some flat ribbon cables come prefolded. Never change the folds on these cables.

●

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 cable 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).

Cable Management 65

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

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.
