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. The power cord must be disconnected 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 how humidity affects the electrostatic voltage levels generated by different activities.
A product can be degraded by 700 volts.
●
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-sensitive 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 containers.
●
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 snugly against bare skin. The ground cord must be connected
to the banana plug connector on the grounding mat or workstation and fit snugly into it.
●
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:
24
●
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.

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 computer.
●
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.

Enabling this feature will save the Master Boot Record (MBR) of the system hard drive. If the MBR gets
changed, the user will be prompted to restore the MBR. Default is disabled.
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.
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.

Solving memory problems
If you encounter memory problems, some common causes and solutions are listed in the following table.
CAUTION: Power may still be supplied to the DIMMs when the computer is turned off (depending on
the Management Engine (ME) settings). To avoid damage to the DIMMs or the system board, you must unplug
the computer power cord before attempting to reseat, install, or remove a memory module.
For those systems that support ECC memory, HP does not support mixing ECC and non-ECC memory. Otherwise,
the computer will not boot the operating system.
NOTE: The memory count will be affected by configurations with the Management Engine (ME) enabled. The
ME uses 8MB of system memory in single channel mode or 16MB of memory in dual-channel mode to
download, decompress, and execute the ME firmware for Out-of-Band (OOB), third-party data storage, and other
management functions.
System will not boot or does not function properly after installing additional memory modules.
Cause
Solution
A memory module is not installed in the DIMM1 or XMM1 socket.

POST error messages and diagnostic front
panel LEDs and audible codes
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.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory test. Full
Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish
the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.
NOTE:
For more information on Computer Setup, see Computer Setup (F10) Utility on page 49.

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: administrator password and power-on password. When you establish only an administrator
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 administrator password will give you
access to Computer Setup.
When both passwords are set, the administrator 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 one or both passwords, you can clear all passwords by powering off the system, opening the cover,
temporarily removing the CLR_PSWD jumper, and booting once. This will erase the administrator and power-on
passwords. You must restore the jumper to create new passwords.
The computer’s configuration memory (CMOS) stores information about the computer’s configuration.
The CMOS jumper resets CMOS but does not clear the power-on and setup passwords.
CAUTION: Resetting the CMOS with power removed will reset the BIOS settings to factory defaults. It may be
useful to back up the BIOS settings or save them as custom defaults before resetting them in case they are
needed later. Back up can be performed in Computer Setup or using the BiosConfigUtility tool available from
www.hp.com. See Computer Setup (F10) Utility on page 49 for information on backing up the BIOS settings.
Resetting CMOS resets BIOS settings to default, but does not clear the passwords or affect any of the other
Security settings. On Intel systems with advanced manageability features, resetting CMOS will also partially
unprovision AMT.
CAUTION: Stringent security is a mode where there is no physical bypass of the password function. If enabled,
removing the password jumper will be ignored. To enable this mode, change the security setting Clear Password
Jumper in Password Policies to Ignore.
If you lose or forget the password when in stringent security mode, the system can only be reset by System
Management Command. This is a way for HP Service and Support to provide a secure method to access the BIOS
and command a password reset for a specifically identified unit under the direction of the owner. This scenario
may not be covered under warranty.
To prevent needing a customer service event to restore access to the system, record your configured
administrator and power-on passwords in a safe place away from your computer.
NOTE: You will receive POST error messages after clearing CMOS and rebooting advising you that configuration
changes have occurred. Use Computer Setup to reset any special system setups along with the date and time.
CAUTION: 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 49 for
information on backing up the CMOS settings.

Statement of memory volatility
The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business PCs.
This chapter also provides general instructions for restoring nonvolatile memory that can contain personal data
after the system has been powered off and the hard drive has been removed.
HP Business PC products that use Intel®-based or AMD®-based system boards contain volatile DDR memory.
The amount of nonvolatile memory present in the system depends upon the system configuration. Intel-based
and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped from HP,
assuming that no subsequent modifications have been made to the system and assuming that no applications,
features, or functionality have been added to or installed on the system.
Following system shutdown and removal of all power sources from an HP Business PC system, personal data
can remain on volatile system memory (DIMMs) for a finite period of time and will also remain in nonvolatile
memory. Use the steps below to remove personal data from the PC, including the nonvolatile memory found in
Intel-based and AMD-based system boards.

What is a UEFI BIOS, and how is it different from a legacy BIOS?
The Unified Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface between
the platform firmware and an operating system (OS). It is a replacement for the older BIOS architecture, but
supports much of the legacy BIOS functionality.
Like the legacy BIOS, the UEFI BIOS provides an interface to display the system information and
configuration settings and to change the configuration of your computer before an OS is loaded. BIOS
provides a secure run-time environment that supports a Graphic User Interface (GUI). In this environment,
you can use either a pointing device (Touchscreen, TouchPad, pointing stick, or USB mouse) or the keyboard
to navigate and make menu and configuration selections. The UEFI BIOS also contains basic system
diagnostics.
The UEFI BIOS provides functionality beyond that of the legacy BIOS. In addition, the UEFI BIOS works to
initialize the computer’s hardware before loading and executing the OS; the run-time environment allows
the loading and execution of software programs from storage devices to provide more functionality, such
as advanced hardware diagnostics (with the ability to display more detailed system information) and
advanced firmware management and recovery software.
HP has provided options in Computer Setup (BIOS) to allow you to run in legacy BIOS, if required by the
operating system. Examples of this requirement would be if you upgrade or downgrade the OS.
3.
Where does the UEFI BIOS reside?
The UEFI BIOS resides on a flash memory chip. A utility is required to write to the chip.
4.
What kind of configuration data is stored on the DIMM Serial Presence Detect (SPD) memory board? How
would this data be written?
The DIMM SPD memory contains information about the memory board, such as size, serial number, data
width, speed/timing, voltage, and thermal information. This information is written by the board
manufacturer and stored on an EEPROM. This EEPROM cannot be written to when the memory board is
installed in a PC. Third-party tools do exist that can write to the EEPROM when the memory board is not
installed in a PC. Various third-party tools are available to read SPD memory.
5.
What is meant by “Restore the nonvolatile memory found in Intel-based system boards”?
This message relates to clearing the Real Time Clock (RTC) CMOS memory that contains PC
configuration data.
6.
How can the BIOS security be reset to factory defaults and data erased?
112 Appendix B Statement of memory volatility
IMPORTANT:
Resetting will result in the loss of information.
These steps will not reset Custom Secure Boot Keys. See question and answer 7 for information about
resetting the keys.

How can the Custom Secure Boot Keys be reset?
Secure Boot is a feature to ensure that only authenticated code can start on a platform. If you enabled
Secure Boot and created Custom Secure Boot Keys, simply disabling Secure Boot will not clear the keys.
You must also select to clear the Custom Secure Boot Keys. Use the same Secure Boot access procedure
you used to create the Custom Secure Boot Keys, but make the selection to clear or delete all Secure Boot
Keys.
a.
Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu”
message is displayed at the bottom of the screen.
b.
Select the Security menu, select Secure Boot Configuration, and then follow the on-screen

c.
At the Secure Boot Configuration window, select Secure Boot, select Clear Secure Boot Keys, and then
follow the on-screen instructions to continue.
Using HP Sure Start
Select computer models are configured with HP Sure Start, a technology that continuously monitors your
computer's BIOS for attacks or corruption. If the BIOS becomes corrupted or is attacked, HP Sure Start restores
the BIOS to its previously safe state, without user intervention. Those select computer models ship with HP Sure
Start configured and enabled. HP Sure Start is configured and already enabled so that most users can use the HP
Sure Start default configuration. The default configuration can be customized by advanced users.
To access the latest documentation on HP Sure Start, go to http://www.hp.com/support, and select your country.
