Service considerations
The following sections include some of the considerations that you must keep in mind during disassembly
and assembly procedures.
NOTE: As you remove each subassembly from the computer, place the subassembly (and all accompanying
screws) away from the work area to prevent damage.
Plastic parts
CAUTION: Using excessive force during disassembly and reassembly can damage plastic parts. Use care
when handling the plastic
28 Chapter 4 Removal and replacement procedures preliminary requirements
Cables and connectors
CAUTION: When servicing the computer, be sure that cables are placed in their proper locations during
the reassembly process. Improper cable placement can damage the computer.
Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat
the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid
bending, twisting, or tearing cables. Be sure that cables are routed in such a way that they cannot be caught
or snagged by parts being removed or replaced. Handle flex cables with extreme care; these cables tear
easily.
Drive handling
CAUTION: Drives are fragile components that must be handled with care. To prevent damage to
the computer, damage to a drive, or loss of information, observe these precautions:
Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the computer is
off or in Hibernation, turn the computer on, and then shut it down through the operating system.
Before handling a drive, be sure that you are discharged of static electricity. While handling a drive, avoid
touching the connector.
Before removing a diskette drive or optical drive, be sure that a diskette or disc is not in the drive and be sure
that the optical drive tray is closed.
Handle drives on surfaces covered with at least one inch of shock-proof foam.
Avoid dropping drives from any height onto any surface.
Avoid exposing an internal hard drive to products that have magnetic fields, such as monitors or speakers.
Avoid exposing an internal hard drive to products that have magnetic fields, such as monitors or speakers.
Avoid exposing a drive to temperature extremes or liquids.
If a drive must be mailed, place the drive in a bubble pack mailer or other suitable form of protective
packaging and label the package “FRAGILE.”
Service considerations 29
Grounding guidelines
Electrostatic discharge damage
Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine
the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many
cases, ESD contains enough power to alter device parameters or melt silicon junctions.
A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or
microcircuitry. Even if the spark is neither felt nor heard, damage may have occurred.
An electronic device exposed to ESD may not be affected at all and can work perfectly throughout a normal
cycle. Or the device may function normally for a while, then degrade in the internal layers, reducing its life
expectancy.
CAUTION: To prevent damage to the computer when you are removing or installing internal components,
observe these precautions:
Keep components in their electrostatic-safe containers until you are ready to install them.
Before touching an electronic component, discharge static electricity by using the guidelines described in this
section.
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
If you remove a component, place it in an electrostatic-safe container.
The following table shows how humidity affects the electrostatic voltage levels generated by different
activities.
CAUTION: A product can be degraded by as little as 700 V.

Packaging and transporting guidelines
Follow these grounding guidelines when packaging and transporting equipment:
●
●
●
●
●
●
●
To avoid hand contact, transport products in static-safe tubes, bags, or boxes.
Protect ESD-sensitive parts and assemblies with conductive or approved containers or packaging.
Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations.
Place items on a grounded surface before removing items from their containers.
Always be properly grounded when touching a component or assembly.
Store reusable ESD-sensitive parts from assemblies in protective packaging or nonconductive foam.
Use transporters and conveyors made of antistatic belts and roller bushings. Be sure that mechanized
equipment used for moving materials is wired to ground and that proper materials are selected to avoid
static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
Workstation guidelines
Follow these grounding workstation guidelines:
●
●
Cover the workstation with approved static-shielding material.
Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and
equipment.
●
●
●
Use conductive field service tools, such as cutters, screwdrivers, and vacuums.
When fixtures must directly contact dissipative surfaces, use fixtures made only of static safe materials.
Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and
Styrofoam.
●
Handle ESD-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these
items only at static-free workstations.
●
●
Avoid contact with pins, leads, or circuitry.
Turn off power and input signals before inserting or removing connectors or test equipment.
Grounding guidelines 31
Equipment guidelines
Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.
●
When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a
minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap
snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips
to connect a wrist strap.
●
When standing, use foot straps and a grounded floor mat. Foot straps (heel, toe, or 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 foot straps on both feet with a minimum of one megohm resistance
between the operator and ground. To be effective, the conductive must be worn in contact with the skin.
The following grounding equipment is recommended to prevent electrostatic damage:
●
●

8 HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run diagnostic
tests to determine whether the computer hardware is functioning properly. The tool runs outside
the operating system so that it can isolate hardware failures from issues that are caused by the operating
system or other software components.
When HP PC Hardware Diagnostics (UEFI) detects a failure that requires hardware replacement, a 24-digit
Failure ID is generated. This ID can then be provided to support to help determine how to correct the problem.
NOTE: To start diagnostics on a convertible computer, your computer must be in notebook mode and you
must use the keyboard attached.
To start HP PC Hardware Diagnostics (UEFI), follow these steps:
1. Turn on or restart the computer, quickly press esc.

Creating recovery media and backups
The following methods of creating recovery media and backups are available on select products only. Choose
the available method according to your computer model.
●
Use HP Recovery Manager to create HP Recovery media after you successfully set up the computer. This
step creates a backup of the HP Recovery partition on the computer. The backup can be used to reinstall
the original operating system in cases where the hard drive is corrupted or has been replaced. For
information on creating recovery media, see Creating HP Recovery media (select products only)
on page 73. For information on the recovery options that are available using the recovery media, see
●
Use Windows tools to create system restore points and create backups of personal information.

You can use Windows tools to create system restore points and create backups of personal information,
●
If your computer does list the Recovery partition and the Windows partition, you can use HP Recovery
Manager to create recovery media after you successfully set up the computer. HP Recovery media can be
used to perform system recovery if the hard drive becomes corrupted. System recovery reinstalls
the original operating system and software programs that were installed at the factory and then
configures the settings for the programs. HP Recovery media can also be used to customize the system
or restore the factory image if you replace the hard drive.
◦
◦
◦
Only one set of recovery media can be created. Handle these recovery tools carefully, and keep
them in a safe place.
HP Recovery Manager examines the computer and determines the required storage capacity for
the media that will be required.
To create recovery discs, your computer must have an optical drive with DVD writer capability, and
you must use only high-quality blank DVD-R, DVD+R, DVD-R DL, or DVD+R DL discs. Do not use
rewritable discs such as CD±RW, DVD±RW, double-layer DVD±RW, or BD-RE (rewritable Blu-ray)
discs; they are not compatible with HP Recovery Manager software. Or, instead, you can use a high-
quality blank USB flash drive.
◦
If your computer does not include an integrated optical drive with DVD writer capability, but you
would like to create DVD recovery media, you can use an external optical drive (purchased
separately) to create recovery discs. If you use an external optical drive, it must be connected
directly to a USB port on the computer; the drive cannot be connected to a USB port on an external
device, such as a USB hub. If you cannot create DVD media yourself, you can obtain recovery discs
for your computer from HP. See the Worldwide Telephone Numbers booklet included with

12 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.

Questions and answers
1. How can the BIOS settings be restored (returned to factory settings)?
IMPORTANT: Restore defaults does not securely erase any data on your hard drive. See question and
answer 6 for steps to securely erase data.
Restore defaults does not reset the Custom Secure Boot keys. See question and answer 7 for
information about resetting the 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 Main, and then select Restore defaults.
c. Follow the on-screen instructions.
d. Select Main, select Save Changes and Exit, and then follow the on-screen instructions.
2. 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
module? How would this data be written?
The DIMM SPD memory contains information about the memory module, such as size, serial number,
data width, speed/timing, voltage, and thermal information. This information is written by the module
manufacturer and stored on an EEPROM. This EEPROM cannot be written to when the memory module is
installed in a PC. Third-party tools do exist that can write to the EEPROM when the memory module 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?
86 Chapter 12 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.
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 Main, and then select Reset BIOS Security to Factory Default.
c. Follow the on-screen instructions.
d. Select Main, select Save Changes and Exit, and then follow the on-screen instructions.
7. 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
instructions.
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 models only)
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. Select Drivers & Downloads, and then follow the on-screen instructions.
