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.

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.

Tools required 19

Drive handling

IMPORTANT: 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 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 one 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

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.

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) may not appear to be aected at all and can work perfectly
throughout a normal cycle. The device may 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.

20 Chapter 4 Removal and replacement procedures preliminary requirements

IMPORTANT: To prevent damage to the device 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.

Generating static electricity

Note the following:

● Dierent activities generate dierent amounts of static electricity.

● Static electricity increases as humidity decreases.

Electronic components are multi-packaged inside plastic tubes, trays, or Styrofoam.

NOTE: As little as 700 volts 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.

● 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 21

● 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

Use the following equipment to prevent static electricity damage to electronic components:

● Wrist straps are exible straps with a maximum of one-megohm ± 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 one-megohm ± 10% resistance between the operator and ground.

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 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 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 (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 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 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 data erased?

64 Chapter 10 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 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, 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 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 models 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. The default conguration can be customized by
advanced users.

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