Tools required

You will need the following tools to complete the removal and replacement procedures:

●

Flat-bladed screwdriver

●

Magnetic screwdriver

●

Phillips P0 and P1 screwdrivers

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

Tools required 25

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.”

26 Chapter 4 Removal and replacement procedures preliminary requirements

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 aected 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 aects the electrostatic voltage levels generated by dierent
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

Walking across vinyl oor 12,000 V 5,000 V 3,000 V

Motions of bench worker 6,000 V 800 V 400 V

Removing bubble pack from PCB 26,500 V 20,000 V 7,000 V

Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V

Grounding guidelines 27

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.

28 Chapter 4 Removal and replacement procedures preliminary requirements

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 eective, 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

During the system validation phase that occurs at system startup, the BIOS validates the functionality of the
following subsystems and conditions:

●

AC adapter

●

System board power

●

Processor failure

●

BIOS corruption

●

Memory failure

●

Graphics failure

●

System board failure

●

BIOS authentication failure

If an error is detected, specic patterns of long and short blinks, accompanied by long and short beeps (where
applicable) are used to identify the error. These patterns will make up a two part code:

●

Major – the category of the error

●

Minor – the specic error within the category

NOTE: Single beep/blink codes are not used.

Number of long beeps/blinks Error category

1 Not used

2 BIOS

3 Hardware

4 Thermal

Patterns of blink/beep codes are determined by using the following parameters:

●

1 second pause occurs after the last major blink.

●

2 second pause occurs after the last minor blink.

●

Beep error code sequences occur for the rst 5 iterations of the pattern and then stop.

●

Blink error code sequences continue until the computer is unplugged or the power button is pressed.

NOTE: Not all diagnostic lights and audible codes are available on all models.

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 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 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
conguration settings and to change the conguration 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 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 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 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/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 conguration
data.

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