Table 3-3 Computer Setup—Storage (continued)
Storage OptionseSATA 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
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.

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:

●
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.

●Measure boot variables/devices to PCR1 - Typically, the computer measures the boot path
and saves collected metrics to PCR5 (a register in the Embedded Security Device). Bitlocker
tracks changes to any of these metrics, and forces the user to re-authenticate if it detects
any changes. Enabling this feature lets you set Bitlocker to ignore detected changes to boot
path metrics, thereby avoiding re-authentication issues associated with USB keys inserted in
a port. Default is enabled.
OS management of Embedded Security Device (enable/disable) - This option allows the user to
limit OS control of the Embedded Security Device. Default is enabled. This option is automatically
disabled if Trusted Execution Technology is enabled.
●Reset of Embedded Security Device through OS (enable/disable) - This option allows the
user to limit the operating system ability to request a Reset to Factory Settings of the
Embedded Security Device. Default is disabled.
NOTE: To enable this option, a Setup password must be set.
No PPI provisioning (Windows 8 only) - This option lets you set Windows 8 to bypass the PPI
●
(Physical Presence Interface) requirement and directly enable and take ownership of the
TPM on first boot. You cannot change this setting after TPM is owned/initialized, unless the
TPM is reset. Default is disabled for non-Windows 8 systems, and enabled for Windows 8.
●Allow PPI policy to be changed by OS. Enabling this option allows the operating system to
execute TPM operations without Physical Presence Interface. Default is disabled.
NOTE: To enable this option, a Setup password must be set.

FullBoot Every x Days = Memory count on 1st cold boot on or after the xth day. No
◦
more memory counts until 1st cold boot on or after x days. Clears memory on all boots.
POST messages (enable/disable). Enabling this feature will cause the system to display
●
POST error messages, which are error messages displayed on the monitor during the Power
On Self Test if the BIOS encounters some kind of problem while starting the PC. A POST
error message will only display on screen if the computer is capable of booting this far. If the
POST detects an error before this point, a beep code is generated instead. Default is
disabled.
Press the ESC key for Startup Menu (Enable/Disable). This feature controls the display of
●
the text “Press the ESC key for Startup Menu” during POST. This text does not display on
Windows 8 systems with Fast Boot support. Other text also will not display (for example,
Ownership Tag). Default is enabled.
Option ROM Prompt (enable/disable). Enabling this feature will cause the system to display
●
a message before loading option ROMs. Default is enabled.
●After Power Loss (off/on/previous state). Default is Power off. Setting this option to:
Power off—causes the computer to remain powered off when power is restored.
◦
Power on—causes the computer to power on automatically as soon as power is
◦
restored.

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.
BIOS Power-OnAllows you to set the computer to turn on automatically at a time you specify.

●
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.

AMT ConfigurationAllows you to set:
controller will be the “boot” or primary VGA controller.
●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 9 in the Computer Setup—File table.)

6Routine 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.

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.

●
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 45 before cleaning the
keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in
Computer Case on page 45.
When cleaning debris from under the keys, review all rules in
on page 45 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
●

●
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.
Service Considerations47
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.

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 one 1-GB DIMM and Channel B is populated with one 2-GB DIMM, the system
will operate in dual channel mode.
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is
●
not equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel
Memory53
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 one 1-GB
DIMM, Channel A should be populated with the 2-GB DIMM, and Channel B should be
populated with the 1-GB DIMM. With this configuration, 2 GB will run as dual channel and 1 GB
will run as single channel.
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
●
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
Removing Memory Modules
CAUTION:You must disconnect the power cord and wait approximately 30 seconds for the power
to drain before adding or removing memory modules. Regardless of the power-on state, voltage is
always supplied to the memory modules as long as the computer is plugged into an active AC outlet.
Adding or removing memory modules while voltage is present may cause irreparable damage to the
memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or
oxidation resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.

Cable Management
Always follow good cable management practices when working inside the computer.
Keep cables away from major heat sources like the heat sink.
●
Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these
●
are not designed to take excessive pressure on them.
Some flat ribbon cables come prefolded. Never change the folds on these cables.
●
Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
●
Never crease a SATA data cable.
●
Do not rely on components like the drive cage, power supply, or computer cover to push cables
●
down into the chassis. Always position the cables to lay properly by themselves.
When removing the power supply power cable from the P1 connector on the system board, always
follow these steps:
1.Squeeze on the top of the retaining latch attached to the cable end of the connector (1).
2.Grasp the cable end of the connector and pull it straight up (2).
CAUTION:Always pull the connector - NEVER pull on the cable. Pulling on the cable could
damage the cable and result in a failed power supply.
