4 Removal and replacement procedures
preliminary requirements
Tools required
You will need the following tools to complete the removal and replacement procedures:
●Phillips P0 screwdriver
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
30 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 ex 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
o 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 elds, such as monitors or speakers.
Avoid exposing an internal hard drive to products that have magnetic elds, 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 31
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 nger 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 aected 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 aects the electrostatic voltage levels generated by dierent
activities.
CAUTION: A product can be degraded by as little as 700 V.
Typical electrostatic voltage levels
Relative humidity
Event 10% 40% 55%
Walking across carpet 35,000 V 15,000 V 7,500 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 eld service tools, such as cutters, screwdrivers, and vacuums.
●When xtures must directly contact dissipative surfaces, use xtures 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 o power and input signals before inserting or removing connectors or test equipment.
Grounding guidelines 33
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 exible 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 oor 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
oors or dissipative oor mats, use foot straps on both feet with a minimum of one megohm resistance
between the operator and ground. To be eective, the conductive must be worn in contact with the skin.
The following grounding equipment is recommended to prevent electrostatic damage:
●Antistatic tape
●Antistatic smocks, aprons, and sleeve protectors
●Conductive bins and other assembly or soldering aids
●Nonconductive foam
●Conductive tabletop workstations with ground cords of one megohm resistance
●Static-dissipative tables or oor mats with hard ties to the ground
●Field service kits
●Static awareness labels
●Material-handling packages
●Nonconductive plastic bags, tubes, or boxes
●Metal tote boxes
●Electrostatic voltage levels and protective materials
The following table lists the shielding protection provided by antistatic bags and oor mats.
Material Use Voltage protection level
Antistatic plastics Bags 1,500 V
Carbon-loaded plastic Floor mats 7,500 V
Metallized laminate Floor mats 5,000 V

13 Backing up and recovering Windows 7
Your computer includes HP and Windows tools to help you safeguard your information and retrieve it if you
ever need to. These tools will help you return your computer to a proper working state, all with simple steps.
This section provides information about the following processes:
●Creating recovery media and backups
●Restoring and recovering your system
Creating recovery media and backups
Recovery after a system failure is only as good as your most recent backup.
1. After you successfully set up the computer, create HP Recovery media. This step creates a Windows 7
operating system DVD and a Driver Recovery DVD. The Windows DVD can be used to reinstall the original
operating system in cases where the hard drive is corrupted or has been replaced. The Driver Recovery
DVD installs specic drivers and applications. See Creating recovery media with HP Recovery Disc
Creator on page 109.
2. Use Windows Backup and Recovery tools to perform the following:
●Back up individual les and folders
●Back up your entire hard drive (select models only)
●Create system repair discs (select models only) with the installed optical drive (select models only)
or an optional external optical drive
●Create system restore points
NOTE: This guide describes an overview of backing up, restoring, and recovering options. For more details
about the tools provided, see Help and Support. To access Help and Support, select Start > Help and Support.
NOTE: HP recommends that you print the recovery procedures and save them for later use, in case of
system instability.
In case of system failure, you can use the backup les to restore the contents of your computer. See Backing
up your information on page 110.
Guidelines
●When creating recovery media or backing up to discs, use any of the following types of discs (purchased
separately): DVD+R, DVD+R DL, DVD-R, DVD-R DL, or DVD±RW. The discs you use will depend on the type
of optical drive you are using.
●Be sure that the computer is connected to AC power before you start the recovery media creation
process or the backup process.
Creating recovery media with HP Recovery Disc Creator
HP Recovery Disc Creator is a software program that oers an alternative way to create recovery media. After
you successfully set up the computer, you can create recovery media using HP Recovery Disc Creator. This
recovery media allows you to reinstall your original operating system as well as select drivers and
Creating recovery media and backups 109
applications if the hard drive becomes corrupted. HP Recovery Disc Creator can create two kinds of recovery

You should create system repair media and your initial backup immediately after initial system setup. As you
add new software and data les, you should continue to back up your system on a regular basis to maintain a
reasonably current backup. You should also create Windows system repair media (select models only) which
can be used to start up (boot) the computer and repair the operating system in case of system instability or
failure. Your initial and subsequent backups allow you to restore your data and settings if a failure occurs.
You can back up your information to an optional external hard drive, a network drive, or discs.
Note the following when backing up:
●Store personal les in the Documents library, and back it up regularly.
●Back up templates that are stored in their associated directories.
●Save customized settings that appear in a window, toolbar, or menu bar by taking a screen shot of your
settings. The screen shot can be a time-saver if you have to reset your preferences.
●When backing up to discs, number each disc after removing it from the drive.

16 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 o 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 conguration. Intel-
based and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped from
HP, assuming that no subsequent modications 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 nite 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

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 dierent from a legacy BIOS?
The Unied Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface
between the platform rmware 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
conguration settings and to change the conguration 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 conguration 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 rmware 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 ash memory chip. A utility is required to write to the chip.
4. What kind of conguration 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 conguration
data.
6. How can the BIOS security be reset to factory defaults and data erased?
Questions and answers 121
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 Conguration, and then follow the on-screen
instructions.
c. At the Secure Boot Conguration 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 congured 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 congured and enabled. HP Sure Start is congured and already enabled so that most
users can use the HP Sure Start default conguration. The default conguration 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.
