 3 Routine care, SATA drive guidelines, and
disassembly preparation

This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.

CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system
board. You must disconnect the power cord from the power source before opening the computer to prevent
system board or component damage.

Electrostatic discharge information

A sudden discharge of static electricity from your finger 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 affected 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.

12 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation

Generating static
The following table shows that:
● Different activities generate different amounts of static electricity.
● Static electricity increases as humidity decreases.

Relative Humidity

Event 55% 40% 10%

Walking across carpet 7,500 V 15,000 V 35,000 V

Walking across vinyl floor 3,000 V 5,000 V 12,000 V

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

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

These are then multi-packaged inside plastic tubes, trays, or Styrofoam.

NOTE: 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 damage to electric
components and accessories.
● 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.
● Avoid contact with pins, leads, or circuitry.
● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
foam.

Electrostatic discharge information 13

 Personal grounding methods and equipment
Use the following equipment to prevent static electricity damage to equipment:
● Wrist straps are flexible 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 fit 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 floors or dissipative floor mats, use them on both feet with
a maximum of one-megohm ± 10% resistance between the operator and ground.

Static Shielding Protection Levels

Method Voltage

Antistatic plastic 1,500

Carbon-loaded plastic 7,500

Metallized laminate 15,000

Grounding the work area

To prevent static damage at the work area, use the following 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 off power and input signals before inserting and removing connectors or test equipment.
● Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces.
● Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.
● Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.

Recommended materials and equipment

Materials and equipment that are recommended for use in preventing static electricity include:
● Antistatic tape
● Antistatic smocks, aprons, or sleeve protectors
● Conductive bins and other assembly or soldering aids
● Conductive foam
● Conductive tabletop workstations with ground cord of one-megohm +/- 10% resistance
● Static-dissipative table or floor mats with hard tie to ground
● Field service kits
● Static awareness labels
● Wrist straps and footwear straps providing one-megohm +/- 10% resistance

● Opaque shielding bags
● Transparent metallized shielding bags
● Transparent shielding tubes

Operating guidelines
To prevent overheating and to help prolong the life of the computer:
● Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
● Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented sides
of the computer and above the display to permit the required airflow.
● Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
● Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign matter
can block the vents and limit the airflow. Be sure to unplug the computer before cleaning the air vents.
● Never operate the computer with the cover or side panel removed.
● Do not stack computers on top of each other or place computers so near each other that they are subject
to each other’s re-circulated or preheated air.
● If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be
provided on the enclosure, and the same operating guidelines listed above will still apply.
● Keep liquids away from the computer and keyboard.
● Never cover the ventilation slots with any type of material.
● Install or enable power management functions of the operating system or other software, including
sleep states.

Routine care
General cleaning safety precautions
1. Never use solvents or flammable solutions to clean the computer.
2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use
the cloth on the component.
3. Always unplug the computer when cleaning with liquids or damp cloths.
4. Always unplug the computer before cleaning the keyboard, mouse, or air vents.
5. Disconnect the keyboard before cleaning it.
6. Wear safety glasses equipped with side shields when cleaning the keyboard.

Operating guidelines 15
 Cleaning the Computer Case
Follow all safety precautions in General cleaning safety precautions on page 15 before cleaning the computer.
To clean the computer case, follow the procedures described below:
● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth
or swab dampened with clear water.
● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will evaporate
quickly and not leave a residue.
● After cleaning, always wipe the unit with a clean, lint-free cloth.
● Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and
limit the airflow.

Cleaning the keyboard

Follow all safety precautions in General cleaning safety precautions on page 15 before cleaning the keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the Computer
Case on page 16.
When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 15
before following these procedures:

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the
keys.

● Visible debris underneath or between the keys may be removed by vacuuming or shaking.
● Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too
much air pressure can dislodge lubricants applied under the wide keys.
● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is
available through many electronic supply outlets.

CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are
improperly removed or installed, the keyboard may not function properly.

● Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed out. Be
careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any
fibers or dirt in confined areas. Allow the parts to air dry before reassembly.

Cleaning the display

Wipe the screen with a clean cloth moistened with water or with a towelette designed for cleaning displays.
Do not use sprays or aerosols directly on the screen; the liquid may seep into the housing and damage a
component. Never use solvents or flammable liquids on the display.

Cleaning the mouse

Before cleaning the mouse, ensure that the power to the computer is turned off.
● Clean the mouse ball by first removing the retaining plate and the ball from the housing. Pull out any
debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly.
● To clean the mouse body, follow the procedures in Cleaning the Computer Case on page 16.

16 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation

Service considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.

Tools and software requirements

To service the computer, you need the following:
● Torx T-15 screwdriver
● Torx T-15 screwdriver with small diameter shank (for certain front bezel removal)
● Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
● Phillips #2 screwdriver
● Diagnostics software
● Tamper-resistant T-15 wrench

Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and may
be of different lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP
strongly recommends that all screws removed during disassembly be kept with the part that was removed,
then returned to their proper locations.

CAUTION: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard drives only.
CAUTION: As each subassembly is removed from the computer, it should be placed away from the work area
to prevent damage.

Cables and connectors

Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to
avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from
the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the
cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts
being removed or replaced.

CAUTION: When servicing this computer, ensure that cables are placed in their proper location during the
reassembly process. Improper cable placement can damage the computer.

Hard drives
Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This applies
to failed drives as well as replacement spares.
● If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging

Utilities Hard Drive Utilities

● Save/Restore MBR of System Hard Drive

NOTE: Windows 10 systems are generally not formatted to include an MBR. Instead they use GUID
Partition Table (GPT) format, which better supports large hard drives.

Enabling this feature will save the Master Boot Record (MBR) of the system hard drive. If the MBR
gets changed, the user will be prompted to restore the MBR. Default is disabled.

The MBR contains information needed to successfully boot from a disk and to access the data stored
on the disk. Master Boot Record Security may prevent unintentional or malicious changes to the
MBR, such as those caused by some viruses or by the incorrect use of certain disk utilities. It also
allows you to recover the "last known good" MBR, should changes to the MBR be detected when the
system is restarted.

NOTE: Most operating systems control access to the MBR of the current bootable disk; the BIOS
cannot prevent changes that may occur while the operating system is running.

Restores the backup Master Boot Record to the current bootable disk. Default is disabled.

Only appears if all of the following conditions are true:

– MBR security is enabled

– A backup copy of the MBR has been previously saved

– The current bootable disk is the same disk from which the backup copy was saved

CAUTION: Restoring a previously saved MBR after a disk utility or operating system has modified
the MBR, may cause the data on the disk to become inaccessible. Only restore a previously saved
MBR if you are confident that the current bootable disk's MBR has been corrupted or infected with a
virus.

● Save/Restore GPT of System Hard Drive

Enabling this feature will save the GUID Partition Table (GPT) of the system hard drive. If the GPT is
subsequently changed, the user is prompted to choose whether to restore GPT.

● DriveLock

Allows you to assign or modify a master or user password for hard drives. When this feature is
enabled, the user is prompted to provide one of the DriveLock passwords during POST. If neither is
successfully entered, the hard drive will remain inaccessible until one of the passwords is
successfully provided during a subsequent cold-boot sequence.

Computer Setup (F10) Utilities 67

 Table 5-2 Computer Setup—Security (continued)

Option Description

NOTE: This selection will only appear when at least one drive that supports the DriveLock feature
is attached to the system.

CAUTION: Be aware that these settings take place immediately. A save is not necessary.

CAUTION: Be sure to document the DriveLock password. Losing a DriveLock password will render a
drive permanently locked.

 6 Using HP PC Hardware Diagnostics (UEFI)

HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run diagnostic
tests to determine whether the computer hardware is functioning properly. The tool runs outside the
operating system so that it can isolate hardware failures from issues that are caused by the operating system
or other software components.
When HP PC Hardware Diagnostics (UEFI) detects a failure that requires hardware replacement, a 24-digit
Failure ID code is generated. This ID code can then be provided to support to help determine how to correct
the problem.

NOTE: To start diagnostics on a convertible computer, your computer must be in notebook mode and you
must use the keyboard attached.

To start HP PC Hardware Diagnostics (UEFI), follow these steps:

1. Turn on or restart the computer, and quickly press esc.
2. Press f2.
The BIOS searches three places for the diagnostic tools, in the following order:
a. Connected USB drive

NOTE: To download the HP PC Hardware Diagnostics (UEFI) tool to a USB drive, see Downloading
HP PC Hardware Diagnostics (UEFI) to a USB device on page 74.

b. Hard drive
c. BIOS
3. When the diagnostic tool opens, select the type of diagnostic test you want to run, and then follow the
on-screen instructions.

NOTE: If you need to stop a diagnostic test, press esc.

Click the question mark icon in the taskbar.

IMPORTANT: If you will be performing recovery procedures on a tablet, the tablet battery must be at least
70% charged before you start the recovery process.
IMPORTANT: For a tablet with a detachable keyboard, connect the keyboard to the keyboard dock before
beginning any recovery process.

Creating recovery media and backups

The following methods of creating recovery media and backups are available on select products only. Choose
the available method according to your computer model.
● Use HP Recovery Manager to create HP Recovery media after you successfully set up the computer. This
step creates a backup of the HP Recovery partition on the computer. The backup can be used to reinstall
the original operating system in cases where the hard drive is corrupted or has been replaced. For
information on creating recovery media, see Creating HP Recovery media (select products only)
on page 102. For information on the recovery options that are available using the recovery media, see
Using Windows tools on page 103.
● Use Windows tools to create system restore points and create backups of personal information.
For more information, see Recovering using HP Recovery Manager on page 104.

NOTE: If storage is 32 GB or less, Microsoft System Restore is disabled by default.

Creating HP Recovery media (select products only)

If possible, check for the presence of the Recovery partition and the Windows partition. From the Start menu,
select File Explorer, and then select This PC.
● If your computer does not list the Windows partition and the Recovery partition, you can obtain recovery
media for your system from support. See the Worldwide Telephone Numbers booklet included with the
computer. You can also find contact information on the HP website. Go to http://www.hp.com/support,
select your country or region, and follow the on-screen instructions.

102 Chapter 8 Backing up, restoring, and recovering

 You can use Windows tools to create system restore points and create backups of personal information,
see Using Windows tools on page 103.
● If your computer does list the Recovery partition and the Windows partition, you can use HP Recovery
Manager to create recovery media after you successfully set up the computer. HP Recovery media can be
used to perform system recovery if the hard drive becomes corrupted. System recovery reinstalls the
original operating system and software programs that were installed at the factory and then configures
the settings for the programs. HP Recovery media can also be used to customize the system or restore
the factory image if you replace the hard drive.
– Only one set of recovery media can be created. Handle these recovery tools carefully, and keep
them in a safe place.
– HP Recovery Manager examines the computer and determines the required storage capacity for
the media that will be required.
– To create recovery discs, your computer must have an optical drive with DVD writer capability, and
you must use only high-quality blank DVD-R, DVD+R, DVD-R DL, or DVD+R DL discs. Do not use
rewritable discs such as CD±RW, DVD±RW, double-layer DVD±RW, or BD-RE (rewritable Blu-ray)
discs; they are not compatible with HP Recovery Manager software. Or, instead, you can use a high-
quality blank USB flash drive.
– If your computer does not include an integrated optical drive with DVD writer capability, but you
would like to create DVD recovery media, you can use an external optical drive (purchased
separately) to create recovery discs. If you use an external optical drive, it must be connected
directly to a USB port on the computer; the drive cannot be connected to a USB port on an external
device, such as a USB hub. If you cannot create DVD media yourself, you can obtain recovery discs
for your computer from HP. See the Worldwide Telephone Numbers booklet included with the
computer. You can also find contact information on the HP website. Go to http://www.hp.com/
support, select your country or region, and follow the on-screen instructions.
– Be sure that the computer is connected to AC power before you begin creating the recovery media.
– The creation process can take an hour or more. Do not interrupt the creation process.
– If necessary, you can exit the program before you have finished creating all of the recovery DVDs.
HP Recovery Manager will finish burning the current DVD. The next time you start HP Recovery
Manager, you will be prompted to continue.
To create HP Recovery media:

IMPORTANT: For a tablet with a detachable keyboard, connect the keyboard to the keyboard dock before
beginning these steps.

1. Type recovery in the taskbar search box, and then select HP Recovery Manager.

2. Select Create recovery media, and then follow the on-screen instructions.
If you ever need to recover the system, see Recovering using HP Recovery Manager on page 104.

Backing up, restoring, and recovering in 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

106 Chapter 8 Backing up, restoring, and recovering

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 specific drivers and applications. See Creating recovery media with HP Recovery Disc
Creator on page 107.
2. Use Windows Backup and Recovery tools to perform the following:
● Back up individual files and folders
● Back up your entire hard drive (select products only)
● Create system repair discs (select products only) with the installed optical drive (select products
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, and then select
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 files to restore the contents of your computer. See Backing
up your information on page 108.

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 offers 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
applications if the hard drive becomes corrupted. HP Recovery Disc Creator can create two kinds of recovery
DVDs:
● Windows 7 operating system DVD—Installs the operating system without additional drivers or
applications.
● Driver Recovery DVD—Installs specific drivers and applications only, in the same way that the HP
Software Setup utility installs drivers and applications.

Creating recovery media

NOTE: The Windows 7 operating system DVD can be created only once. Thereafter, the option to create that
media will not be available after you create a Windows DVD.

To create the Windows DVD:

Backing up your information

You should create system repair media and your initial backup immediately after initial system setup. As you
add new software and data files, 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 products 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 files 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.

Interpreting system validation diagnostic front panel LEDs and

audible codes
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, specific 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 specific error within the category

NOTE: Single beep/blink codes are not used.

10 Password security and resetting CMOS

This computer supports security password features, which can be established through the Computer Setup
Utilities menu.
This computer supports two security password features that are established through the Computer Setup
Utilities menu: administrator password and power-on password. When you establish only an administrator
password, any user can access all the information on the computer except Computer Setup. When you
establish only a power-on password, the power-on password is required to access Computer Setup and any
other information on the computer. When you establish both passwords, only the administrator password will
give you access to Computer Setup.
When both passwords are set, the administrator password can also be used in place of the power-on
password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget one or both passwords, you can clear all passwords by powering off the system, opening the
cover, temporarily removing the PSWD jumper, and booting once. This will erase the administrator and
power-on passwords. You must restore the jumper to create new passwords.

CAUTION: Pushing the CMOS button with power removed will reset the BIOS settings to factory defaults. It
may be useful to back up the BIOS settings or save them as custom defaults before resetting them in case
they are needed later. Back up can be performed in Computer Setup or using the BiosConfigUtility tool
available from www.hp.com. See Computer Setup (F10) Utility on page 62 for information on backing up the
BIOS settings.

Resetting the password jumper

CAUTION: Stringent security is a mode where there is no physical bypass of the password function. If
enabled, removing the password jumper will be ignored. To enable this mode, change the security setting
Clear Password Jumper in Password Policies to Ignore.
If you lose or forget the password when in stringent security mode, the system can only be reset by System
Management Command. This is a way for HP Service and Support to provide a secure method to access the
BIOS and command a password reset for a specifically identified unit under the direction of the owner. This
scenario may not be covered under warranty.
To prevent needing a customer service event to restore access to the system, record your configured
administrator and power-on passwords in a safe place away from your computer.

To disable the power-on or administrator password features, or to clear the power-on or administrator
passwords, complete the following steps:

Resetting the password jumper 119

 1. Shut down the operating system properly, then turn off the computer and any external devices, and
disconnect the power cord from the power outlet.
2. With the power cord disconnected, press the power button again to drain the system of any residual
power.

WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to
disconnect the power cord from the wall outlet, and allow the internal system components to cool
before touching.
CAUTION: When the computer is plugged in, the power supply always has voltage applied to the
system board even when the unit is turned off. Failure to disconnect the power cord can result in
damage to the system.
Static electricity can damage the electronic components of the computer or optional equipment. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. See the Safety & Regulatory Information guide for more information.

3. Remove the access panel.

4. Locate the header and jumper.

NOTE: The password jumper is green so that it can be easily identified. For assistance locating the
password jumper and other system board components, see the system board components image at
System board callouts on page 53.

5. Remove the jumper from pins 1 and 2.

6. Place the jumper on either pin 1 or 2, but not both, so that it does not get lost.
7. Replace the access panel and reconnect the external equipment.
8. Plug in the computer and turn on power. Allow the operating system to start. This clears the current
passwords and disables the password features.
9. Shut down the computer, unplug the power, and disconnect the external equipment.
10. Remove the access panel.
11. Place the jumper on pins 1 and 2.
12. Replace the access panel.
13. Reconnect the external equipment and plug in the computer.

120 Chapter 10 Password security and resetting CMOS

Clearing and resetting the BIOS
The CMOS button resets BIOS settings to default, but does not clear the passwords or affect any of the other

 B Statement of memory volatility

The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business
computers. This chapter also provides general instructions for restoring nonvolatile memory that can contain
personal data after the system has been powered off and the hard drive has been removed.
HP Business computer 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 configuration.
Intel-based and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped
from HP, assuming that no subsequent modifications 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 computer system,
personal data can remain on volatile system memory (DIMMs) for a finite period of time and will also remain
in nonvolatile memory. Use the steps below to remove personal data from the computer, including the
nonvolatile memory found in Intel-based and AMD-based system boards.

NOTE: If your tablet has a keyboard base, connect to the keyboard base before beginning steps in this

 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 different from a legacy BIOS?
The Unified Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface
between the platform firmware 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
configuration settings and to change the configuration 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 configuration 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 firmware 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 flash memory chip. A utility is required to write to the chip.
4. What kind of configuration 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
configuration data.
6. How can the BIOS security be reset to factory defaults and data erased?

128 Appendix B 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 Configuration, and then follow the on-screen
instructions.
c. At the Secure Boot Configuration window, select Secure Boot, select Clear Secure Boot Keys, and
then follow the on-screen instructions to continue.
