4 Removal and replacement procedures
preliminary requirements
Use this information to properly prepare to disassemble and reassemble the computer.
Tools required
You need the following tools to complete the removal and replacement procedures:
● Tweezers
● Nonconductive, nonmarking pry tool
● Magnetic Phillips P1 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
Using excessive force during disassembly and reassembly can damage plastic parts.
Cables and connectors
Handle cables with extreme care to avoid damage.
IMPORTANT: 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.
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 so that they cannot be caught or snagged as you remove or replace parts. Handle ex cables with
extreme care; these cables tear easily.
Drive handling
Note the following guidelines when handling drives.
Tools required 25
Page 34
IMPORTANT: Drives are fragile components. Handle them 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 an optical drive, be sure that a disc is not in the drive, and be sure that the optical drive tray
is closed.
Handle drives on surfaces covered with at least 2.54 cm (1 inch) of shock-proof foam.
Avoid dropping drives from any height onto any surface.
After removing a hard drive or an optical drive, place it in a static-proof bag.
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.”
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, screw drivers, 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 polystyrene foam.
● 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.
Electrostatic discharge information
A sudden discharge of static electricity from your nger 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) might not appear to be aected at all and can work perfectly
throughout a normal cycle. The device might 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.
26 Chapter 4 Removal and replacement procedures preliminary requirements
Page 35
IMPORTANT: To prevent damage to the device when you remove or install 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
Personal grounding methods and equipment on page 28.
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.
Generating static electricity
Follow these static electricity guidelines.
● Dierent activities generate dierent amounts of static electricity.
● Static electricity increases as humidity decreases.

Packing PCBs in foam-lined box
Multiple electric components can be packaged together in plastic tubes, trays, or polystyrene foam.
NOTE: As little as 700 V can degrade a product.
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 static electricity
damage to electronic components.
● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.

Page 36
● 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
Using certain equipment can prevent static electricity damage to electronic components.
● Wrist straps are exible straps with a maximum of 1 MΩ ±10% resistance in the ground cords. To
provide proper ground, a strap must be worn snug against bare skin. The ground cord must be
connected and t snugly into the banana plug connector on the grounding mat or workstation.
● Heel straps/Toe straps/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 them on both feet with
a maximum of 1 MΩ ±10% resistance between the operator and ground.

Questions and answers
Use this section to answer your questions about nonvolatile memory.
1. How can the BIOS settings be restored (returned to factory settings)?
IMPORTANT: The restore defaults feature does not securely erase any data on your hard drive. See
question and answer 6 for steps to securely erase data.
The restore defaults feature 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 quickly press esc.
b. Select Main, and then select Apply Factory Defaults and Exit.
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 replaces 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 runtime environment that supports a Graphic User Interface (GUI). In this environment,
you can use either a pointing device (touch screen, 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 runtime 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 is the UEFI BIOS located?
The UEFI BIOS is located on a ash memory chip. You must use a utility 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 and timing, voltage, and thermal information. This information is written by the
module manufacturer and stored on an EEPROM. You cannot write to this EEPROM when the memory
module is installed in a computer. Third-party tools do exist that can write to the EEPROM when the
memory module is not installed in a computer. 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 computer
conguration data.
6. How can the BIOS security be reset to factory defaults and erase the data?
74 Chapter 10 Statement of memory volatility
Page 83
IMPORTANT: Resetting results in the loss of information.
These steps do 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 quickly press esc.
b. Select Main, and then select Reset Security to Factory Defaults.
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, disabling Secure Boot does not clear the keys. You
must also select to clear the Custom Secure Boot Keys. Use the same Secure Boot access procedure that
you used to create the Custom Secure Boot Keys, but select to clear or delete all Secure Boot Keys.
a. Turn on or restart the computer, and then quickly press esc.
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 products 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. Advanced users can customize the default conguration.

Questions and answers
Use this section to answer your questions about nonvolatile memory.
1. How can the BIOS settings be restored (returned to factory settings)?
IMPORTANT: The restore defaults feature does not securely erase any data on your hard drive. See
question and answer 6 for steps to securely erase data.
The restore defaults feature 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 quickly press esc.
b. Select Main, and then select Apply Factory Defaults and Exit.
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 replaces 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 runtime environment that supports a Graphic User Interface (GUI). In this environment,
you can use either a pointing device (touch screen, 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 runtime 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 is the UEFI BIOS located?
The UEFI BIOS is located on a ash memory chip. You must use a utility 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 and timing, voltage, and thermal information. This information is written by the
module manufacturer and stored on an EEPROM. You cannot write to this EEPROM when the memory
module is installed in a computer. Third-party tools do exist that can write to the EEPROM when the
memory module is not installed in a computer. 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 computer
conguration data.
6. How can the BIOS security be reset to factory defaults and erase the data?
80 Chapter 11 Statement of memory volatility
Page 89
IMPORTANT: Resetting results in the loss of information.
These steps do 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 quickly press esc.
b. Select Main, and then select Reset Security to Factory Defaults.
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, disabling Secure Boot does not clear the keys. You
must also select to clear the Custom Secure Boot Keys. Use the same Secure Boot access procedure that
you used to create the Custom Secure Boot Keys, but select to clear or delete all Secure Boot Keys.
a. Turn on or restart the computer, and then quickly press esc.
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 products 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. Advanced users can customize the default conguration.
