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

● Torx T5 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 17

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.

● 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 aected 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.

18 Chapter 4 Removal and replacement procedures preliminary requirements

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 20.

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.

● Dierent activities generate dierent 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.

● Protect all electrostatic 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 container.

● Always be properly grounded when touching a sensitive component or assembly.

Electrostatic discharge information 19

● 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.

Grounding the work area

To prevent static damage at the work area, follow these precautions.

● Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the

work surface and properly grounded tools and equipment.

● Use static-dissipative mats, foot straps, or air ionizers to give added protection.

● Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle

them only at static-free work areas.

● Turn o power and input signals before inserting and removing connectors or test equipment.

● Use xtures made of static-safe materials when xtures must directly contact dissipative surfaces.

● Keep work area free of nonconductive materials such as ordinary plastic assembly aids and polystyrene

foam.

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 dierent from a legacy BIOS?

The Unied 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
conguration settings and to change the conguration 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 conguration 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 conguration 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
conguration data.

6. How can the BIOS security be reset to factory defaults and erase the data?

Questions and answers 51

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 Conguration, and then follow the on-screen

instructions.

c. At the Secure Boot Conguration 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 congured 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 congured and enabled. HP
Sure Start is congured and already enabled so that most users can use the HP Sure Start default
conguration. Advanced users can customize the default conguration.

To access the latest documentation on HP Sure Start, go to http://www.hp.com/support.
