If an MXM graphics card is installed, all three monitor ports are active. The integrated graphics operate
DisplayPort2 (top port). The MXM/ATI drivers operate DisplayPort1 (bottom port) and VGA. If the integrated
graphics are disabled in the BIOS settings, DisplayPort2 (top port) will not be active.
If an MXM graphics card is not installed, all three monitor ports are driven by the integrated graphics on the Intel
3rd Generation configurations. On some models, all three monitor ports are active but there are some limitations.
For example, if a DisplayPort to DVI or HDMI adapter is installed, the VGA port will not be active. On other models,
only one DisplayPort can be active. Either DisplayPort will function, but only one can be used.
When a DisplayPort to single-link DVI or DisplayPort to HDMI adapter is installed, the VGA port will not be active.
This is because when one of the above adapters is used, it is not considered a true DisplayPort and will function as
the other type of port. This is not an issue with a DisplayPort to dual-link DVI adapter.
When a device is plugged into the blue Line-In Audio Connector, a dialog box will pop up asking if you want to use
the connector for a line-in device or a microphone. You can reconfigure the connector at any time by double-
clicking the Realtek HD Audio Manager icon in the Windows taskbar.

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

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.

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.
28 Chapter 3 Computer Setup (F10) Utility
Table 3-6 Computer Setup—Advanced (for advanced users) (continued)
BIOS Power-On Allows you to set the computer to turn on automatically at a time you specify.
Onboard Devices 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.
Bus Options 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.
Device Options 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.
Computer Setup (F10) Utilities 29
Table 3-6 Computer Setup—Advanced (for advanced users) (continued)
VGA Configuration Displayed only if there is an add-in video card in the system. Allows you to specify which VGA
controller will be the “boot” or primary VGA controller.
AMT Configuration 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.)

5 Routine Care, SATA Drive Guidelines,
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.

68 Chapter 5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation
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.
Cleaning the Computer Case
Follow all safety precautions in General Cleaning Safety Precautions on page 69 before cleaning the
computer.
Operating Guidelines 69
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 69 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 69.
When cleaning debris from under the keys, review all rules in General Cleaning Safety Precautions
on page 69 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 69.
70 Chapter 5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation
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 69.
Service Considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.
Power Supply Fan
The power supply fan is a variable-speed fan based on the temperature in the power supply.
CAUTION: The cooling fan is always on when the computer is in the “On” mode. The cooling fan is
off when the computer is in “Standby,” “Suspend,” or “Off” modes.
You must disconnect the power cord from the power source before opening the computer to prevent
system board or component damage.
Tools and Software Requirements
To service the computer, you need the following:
●Torx T-15 screwdriver (HP screwdriver with bits, PN 161946-001)
●Torx T-15 screwdriver with small diameter shank (for certain front bezel removal)
●Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
●Phillips #2 screwdriver
●Diagnostics software
●HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamper-
resistant bits (Smart Cover FailSafe Key, PN 166527-002)
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.
Service Considerations 71
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 Electrostatic Discharge Information on page 66
●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.
Lithium Coin Cell Battery
The battery that comes with the computer provides power to the real-time clock and has a minimum
lifetime of about three years.
See the appropriate removal and replacement chapter for the chassis you are working on in this
guide for instructions on the replacement procedures.
WARNING! This computer contains a lithium battery. There is a risk of fire and chemical burn if the
battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose
in water or fire, or expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the
battery.
NOTE: Batteries, battery packs, and accumulators should not be disposed of together with the
general household waste. In order to forward them to recycling or proper disposal, please use the
public collection system or return them to HP, their authorized partners, or their agents.

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.
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.
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.
●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.
SATA Hard Drives 73
●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.

4-GB, PC3-12800 671613-001
2-GB, PC3-12800 671612-001
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 16-GB of memory configured in a
high-performing dual channel mode.
DDR3-SDRAM DIMMs
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The
processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system
board, it can cause the physical damage to the DIMM or invoke system malfunction.
82 Chapter 6 Removal and Replacement Procedures Convertible Minitower (CMT) Chassis
For proper system operation, the DDR3-SDRAM DIMMs must be:
●industry-standard 240-pin
●unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
●1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
●support CAS latency 11 DDR3 1600 MHz (11-11-11 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
NOTE: The system will not operate properly if you install unsupported DIMMs.
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
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 1-GB DIMMs 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. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-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.
Memory 83
Installing DIMMs
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. For more information, refer to Electrostatic Discharge Information on page 66.
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 75).
2. Remove the computer access panel (Access Panel on page 76).
3. Open both latches of the memory module socket (1), and insert the memory module into the
socket (2).
Figure 6-7 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module
with the tab on the memory socket.
Populate the black DIMM sockets before the white DIMM sockets.
For maximum performance, populate the sockets so that the memory capacity is spread as
equally as possible between Channel A and Channel B. Refer to Populating DIMM Sockets
on page 83 for more information.
84 Chapter 6 Removal and Replacement Procedures Convertible Minitower (CMT) Chassis
4. Push the module down into the socket, ensuring that the module is fully inserted and properly
seated. Make sure the latches are in the closed position (3).
5. Repeat steps 3 and 4 to install any additional modules.
6. Replace the computer access panel.
7. Reconnect the power cord and turn on the computer.

Memory
Description Spare part number

4-GB, PC3-12800 671613-001
2-GB, PC3-12800 671612-001
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 16-GB of memory configured in a
high-performing dual channel mode.
DDR3-SDRAM DIMMs
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The
processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system
board, it can cause the physical damage to the DIMM or invoke system malfunction.
For proper system operation, the DDR3-SDRAM DIMMs must be:
●industry-standard 240-pin
●unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
●1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
●support CAS latency 11 DDR3 1600 MHz (11-11-11 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
NOTE: The system will not operate properly if you install unsupported DIMMs.
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
128 Chapter 7 Removal and Replacement Procedures Microtower (MT) Chassis
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 1-GB DIMMs 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. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-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.
Installing DIMMs
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. For more information, refer to Electrostatic Discharge Information on page 66.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

Figure 7-6 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module
with the tab on the memory socket.
Populate the black DIMM sockets before the white DIMM sockets.
For maximum performance, populate the sockets so that the memory capacity is spread as
equally as possible between Channel A and Channel B. Refer to Populating DIMM Sockets
on page 128 for more information.
4. Push the module down into the socket, ensuring that the module is fully inserted and properly

Memory
Description Spare part number
8-GB, PC3-12800 689375-001
4-GB, PC3-12800 671613-001
2-GB, PC3-12800 671612-001
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 16-GB of memory configured in a
high-performing dual channel mode.
DDR3-SDRAM DIMMs
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The
processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system
board, it can cause the physical damage to the DIMM or invoke system malfunction.
For proper system operation, the DDR3-SDRAM DIMMs must be:
●industry-standard 240-pin
●unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
●1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
●support CAS latency 11 DDR3 1600 MHz (11-11-11 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
NOTE: The system will not operate properly if you install unsupported DIMMs.
Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
Memory 169
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 1-GB DIMMs 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. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-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.
Installing DIMMs
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. For more information, refer to Electrostatic Discharge Information on page 66.
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 163).
2. Remove the access panel (Access Panel on page 164).
3. Rotate up the internal drive bay housing to access the memory module sockets on the system
board.
170 Chapter 8 Removal and Replacement Procedures Small Form Factor (SFF) Chassis
4. Open both latches of the memory module socket (1), and insert the memory module into the
socket (2).
Figure 8-6 Installing a DIMM
NOTE: A memory module can be installed in only one way. Match the notch on the module
with the tab on the memory socket.
Populate the black DIMM sockets before the white DIMM sockets.
For maximum performance, populate the sockets so that the memory capacity is spread as
equally as possible between Channel A and Channel B. Refer to Populating DIMM Sockets
on page 169 for more information.
5. Push the module down into the socket, ensuring that the module is fully inserted and properly
seated. Make sure the latches are in the closed position (3).
6. Repeat steps 4 and 5 to install any additional modules.
7. Replace the access panel.
8. If the computer was on a stand, replace the stand.
9. Reconnect the power cord and turn on the computer.
10. Lock any security devices that were disengaged when the access panel was removed.
The computer should automatically recognize the additional memory the next time you turn on the
computer.

4-GB, PC3-12800, SODIMM 689373-001
2-GB, PC3-12800, SODIMM 689372-001
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) small outline dual inline memory modules (SODIMMs).
SODIMMs
The memory sockets on the system board can be populated with up to two industry-standard
SODIMMs. These memory sockets are populated with at least one preinstalled SODIMM. To achieve
the maximum memory support, you can populate the system board with up to 8-GB of memory.
DDR3-SDRAM SODIMMs
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The
processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system
board, it can cause the physical damage to the SODIMM or invoke system malfunction.
For proper system operation, the SODIMMs must be:
●industry-standard 204-pin
●unbuffered non-ECC PC3-12800 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:
●512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
●single-sided and double-sided SODIMMS
●SODIMMs constructed with x8 and x16 devices; SODIMMs constructed with x4 SDRAM are not
supported
NOTE: The system will not operate properly if you install unsupported SODIMMs.
214 Chapter 9 Removal and Replacement Procedures Ultra-Slim Desktop (USDT) Chassis
Populating SODIMM Sockets
There are two SODIMM sockets on the system board, with one socket per channel. The sockets are
labeled XMM1 and XMM3. The XMM1 socket operates in memory channel A. The XMM3 socket
operates in memory channel B.
Figure 9-7 SODIMM Socket Locations
Table 9-1 SODIMM Socket Locations
Item Description System Board Label Socket Color
1 SODIMM1 socket, Channel B XMM1 Black
2 SODIMM3 socket, Channel A XMM3 Black
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the SODIMMs are installed.
●The system will operate in single channel mode if the SODIMM sockets are populated in one
channel only.
●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.
●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.
●In any mode, the maximum operational speed is determined by the slowest SODIMM in the
system.
Memory 215
Installing SODIMMs
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. For more information, refer to Electrostatic Discharge Information on page 66.

12 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 16 for information on
backing up the CMOS settings.
305
Resetting the Password Jumper
CAUTION: If you enable the stringent security feature in Computer Setup and you forget the setup
password or the power-on password, the computer is inaccessible and can no longer be used.
Enabling the stringent password disables the ability to reset the password by moving the jumper on
the system board.
If you lose or forget the password, the system board must be replaced. This scenario is not covered
under warranty.
To prevent the computer from becoming permanently unusable, record your configured setup
password or power-on password in a safe place away from your computer. Without these passwords,
the computer cannot be unlocked.
To disable the power-on or setup password features, or to clear the power-on or setup passwords,
complete the following steps:
1. Shut down the operating system properly, then turn off the computer and any external devices,
and disconnect the power cord from the power outlet.
2. With the power cord disconnected, press the power button again to drain the system of any
residual power.
WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be
sure to disconnect the power cord from the wall outlet, and allow the internal system
components to cool before touching.
CAUTION: When the computer is plugged in, the power supply always has voltage applied to
the system board even when the unit is turned off. Failure to disconnect the power cord can
result in damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment.
Before beginning these procedures, ensure that you are discharged of static electricity by briefly
touching a grounded metal object. See the Safety & Regulatory Information guide for more
information.
3. Remove the computer cover or access panel.
4. Locate the header and jumper.
NOTE: The password jumper is green so that it can be easily identified. For assistance
locating the password jumper and other system board components, see the Illustrated Parts &
Service Map (IPSM). The IPSM can be downloaded from http://www.hp.com/support.
5. Remove the jumper from pins 1 and 2. Place the jumper on either pin 1 or 2, but not both, so
that it does not get lost.
6. Replace the computer cover or access panel.
7. Reconnect the external equipment.
8. Plug in the computer and turn on power. Allow the operating system to start. This clears the
current passwords and disables the password features.
9. To establish new passwords, repeat steps 1 through 4, replace the password jumper on pins 1
and 2, then repeat steps 6 through 8. Establish the new passwords in Computer Setup.

13 HP PC Hardware Diagnostics
To help troubleshoot and diagnose failures, use the UEFI-based hardware diagnostic solution that HP
includes on all products. This tool can even be used if the computer will not boot to the operating
system.
Why run HP PC Hardware Diagnostics – UEFI
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 -
UEFI
To access the UEFI diagnostics:
1. Restart or turn on the computer and press Esc repeatedly until the BIOS boot menu appears.
2. Press F2 or select Diagnostics (F2).
