CAUTION: Do not add optional hardware or third-party devices to the computer until the operating
system is successfully installed. Doing so may cause errors and prevent the operating system from
installing properly.
NOTE: Be sure there is a 10.2-cm (4-inch) clearance at the back of the unit and above the monitor
to permit the required airflow.
Installing the operating system
The first time you turn on the computer, the operating system is installed automatically. This process
takes about 5 to 10 minutes, depending on which operating system is being installed. Carefully read
and follow the instructions on the screen to complete the installation.
CAUTION: 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 may
damage the software that runs the computer or prevent its proper installation.
NOTE: If the computer shipped with more than one operating system language on the hard drive,
the installation process could take up to 60 minutes.

Storage Options
SATA Emulation
Allows you to choose how the SATA controller and devices are accessed by the operating
system. There are two supported options: AHCI and IDE.
AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take
advantage of more advanced features of the SATA controller.
IDE - This is the most backwards-compatible setting of the two options. Operating systems usually
do not require additional driver support in IDE mode.
NOTE: The AHCI device driver must be installed prior to attempting to boot from an AHCI
volume. If you attempt to boot from an AHCI volume without the required device driver installed,
the system will crash (blue screen).
DPS Self-Test
Allows you to execute self-tests on ATA hard drives capable of performing the Drive Protection
System (DPS) self-tests.
NOTE: This selection will only appear when at least one drive capable of performing the DPS
self-tests is attached to the system.
Boot Order
Allows you to:
●
Specify the order in which UEFI boot sources and legacy boot sources (such as a USB flash
media device, hard drive, optical drive, or network interface card) 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).
Press F5 to disable a device. Press Enter to select a device. Press the arrow keys to drag a
selected device.
NOTE: MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating
system has started.
Shortcut to Temporarily Override Boot Order

computer and press F9 before the computer boots to the operating system. After POST is
completed, a list of bootable devices is displayed. Use the arrow keys to select the preferred
bootable device and press Enter. The computer then boots from the selected non-default device
for this one time.

Slot Security
Allows you to disable or enable the PCI Express x1 slot. Default is enabled.
Network Boot
Enables/disables the computer’s ability to boot from an operating system installed on a network
server. (Feature available on NIC models only). Default is enable.
System IDs
Allows you to set:
Master Boot Record
Security
●
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.

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.
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.
Press F2 or select Diagnostics (F2).
Pressing F2 signals the system to search for the diagnostics in the following locations:
a.

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
23
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.
25
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.

●
Different activities generate different amounts of static electricity.

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.
26
●
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.
Chapter 6 Routine Care and Disassembly Preparation
●
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:
28
●
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.
●

work area to prevent damage.
30
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

Memory
Memory modules are located on the right side of the computer (viewed from behind). The computer
has two memory slots.
Figure 7-28 Memory module location
For proper system operation, the SODIMMs must be:
●
industry-standard 204-pin
●
unbuffered non-ECC PC3-10600 DDR3-1600 MHz-compliant
●
1.5 volt DDR3-SDRAM SODIMMs
The DDR3-SDRAM SODIMMs must also:
●
support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)
●
contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
In addition, the computer supports:
●
1-Gbit, 2-Gbit, and 4-Gbit non-ECC memory technologies
●
single-sided and double-sided SODIMMS
●
SODIMMs constructed with x8 and x16 SDRAMs; SODIMMs constructed with x4 SDRAMs are
not supported
NOTE:
The system will not operate properly if you install unsupported SODIMM memory.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the SODIMMs are installed. Refer to the following table to identify the SODIMM
channel locations.

●
The system will operate in single channel mode if the SODIMM sockets are populated in one
channel only.
●
The system will operate in flex mode if the memory capacity of the SODIMM in Channel A is not
equal to the memory capacity of the SODIMM 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. If one channel will have more memory
than the other, the larger amount should be assigned to channel A.
●
The system will operate in a higher-performing dual channel mode if the memory capacity of the
SODIMM in Channel A is equal to the memory capacity of the SODIMM in Channel B.
●
In any mode, the maximum operational speed is determined by the slowest SODIMM in the
system.

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.

10 Password Security and Resetting
CMOS
This computer supports security password features, which can be established through the Computer
Setup Utilities menu.
This computer supports two security password features that are established through the Computer
Setup Utilities menu: setup password and power-on password. When you establish only a setup
password, any user can access all the information on the computer except Computer Setup. When
you establish only a power-on password, the power-on password is required to access Computer
Setup and any other information on the computer. When you establish both passwords, only the
setup password will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on
password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget the password for the computer, you can clear that password so you can gain access to
the information on the computer by resetting the password jumper.
CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to
back up the computer CMOS settings before resetting them in case they are needed later. Back up is
easily done through Computer Setup. See Computer Setup (F10) Utility on page 11 for information.
