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.

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.

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.

●
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 Cleaning the
Computer Case on page 12.
When cleaning debris from under the keys, review all rules in General Cleaning Safety Precautions
on page 12 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.
●

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.

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.
CAUTION: Consult your eSATA drive and cable manufacturer before enabling 3.0 Gpbs speed.
Some drive and cable combinations may not run reliably at 3.0 Gpbs.

included for consideration as a bootable operating system source.
EFI boot sources always have precedence over legacy boot sources.
●
Legacy Boot Sources: Specify the order in which legacy boot sources (such as a network
interface card, internal hard drive, USB optical drive, or internal optical drive) are checked for
a bootable operating system image. Each device on the list may be individually excluded
from or included for consideration as a bootable operating system source.
Specify the order of attached hard drives. The first hard drive in the order will have priority in
the boot sequence and will be recognized as drive C (if any devices are attached).
NOTE: To drag a device to a preferred place, press Enter. To remove the device from
consideration as a bootable device, press F5.
You can use F5 to disable individual boot items, as well as disable EFI boot and/or legacy boot.

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.

Media card will not work in a digital camera after formatting it in Windows.
Cause
Solution
By default, Windows will format any media card with a
capacity greater than 32MB with the FAT32 format. Some
digital cameras use the FAT (FAT16 & FAT12) format and
can not operate with a FAT32 formatted card.
Either format the media card in the digital camera or select
FAT file system to format the media card in a computer with
Windows.

Solving Memory Problems
If you encounter memory problems, some common causes and solutions are listed in the following
table.
CAUTION: Power may still be supplied to the DIMMs when the computer is turned off (depending
on the Management Engine (ME) settings). To avoid damage to the DIMMs or the system board, you
must unplug the computer power cord before attempting to reseat, install, or remove a memory
module.
For those systems that support ECC memory, HP does not support mixing ECC and non-ECC
memory. Otherwise, the computer will not boot the operating system.
NOTE: The memory count will be affected by configurations with the Management Engine (ME)
enabled. The ME uses 8MB of system memory in single channel mode or 16MB of memory in dualchannel mode to download, decompress, and execute the ME firmware for Out-of-Band (OOB), thirdparty data storage, and other management functions.

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.

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.

The diameter of the wire must be a minimum of 0.75 mm2 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.
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.
