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

SATA Defaults
Computer Setup (F10) Utilities19
Table 3-3 Computer Setup—Storage (continued)
Storage OptionseSATA Port (some models)
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
NOTE: eSATA is not available on USDT systems.
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).
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.
www.hp.com.
NOTE: RAID is not available on USDT systems.
Removable Media Boot
Enables/disables ability to boot the system from removable media. Default is enabled.
Max eSATA Speed (some models)
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.

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.

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.

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.

66Chapter 5 Routine Care, SATA Drive Guidelines, 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 66 before cleaning the
keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in
Computer Case on page 66.
When cleaning debris from under the keys, review all rules in
on page 66 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

●
HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamper-
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.
68Chapter 5 Routine Care, SATA Drive Guidelines, 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
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.
Electrostatic Discharge Information on page 63

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.
70Chapter 5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation
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.
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.
Adherence to the procedures and precautions described in this chapter is essential for proper service.
After completing all necessary removal and replacement procedures, run the Diagnostics utility to
verify that all components operate properly.
NOTE:Not all features listed in this guide are available on all computers.
Preparation for Disassembly
See Routine Care, SATA Drive Guidelines, and Disassembly Preparation on page 63 for initial safety
procedures.
1.Remove/disengage any security devices that prohibit opening the computer.
2.Close any open software applications.
3.Exit the operating system.

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) 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.
Memory79
For proper system operation, the DDR3-SDRAM DIMMs must be:
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.

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
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

Figure 6-7 Installing a DIMM
Access Panel on page 73).
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
on page 80 for more information.
