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 flex cables with extreme care; these cables tear
easily.

Tools required 33
 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
off 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.
After removing a hard drive, an optical drive, or a diskette drive, place it in a static-proof bag.
Avoid exposing an internal hard drive to products that have magnetic fields, 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.

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 finger 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 affected 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 affects the electrostatic voltage levels generated by
different activities.

CAUTION: A product can be degraded by as little as 700 V.

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 non-conductive 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 field service tools, such as cutters, screwdrivers, and vacuums.
When fixtures must directly contact dissipative surfaces, use fixtures 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 off power and input signals before inserting or removing connectors or test equipment.

Grounding guidelines 35
 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 flexible 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 floor 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
floors or dissipative floor mats, use foot straps on both feet with a minimum of one megohm resistance
between the operator and ground. To be effective, 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 floor 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 floor mats.

9 Backing up, restoring, and recovering in
Windows 7

Your computer includes tools provided by the operating system and HP to help you safeguard your
information and retrieve it if ever needed.

Creating backups
1. Use HP Recovery Manager to create recovery media immediately after you set up the working computer.
2. As you add hardware and software programs, create system restore points.
3. As you add photos, video, music, and other personal files, create a backup of your system and personal
information.

Creating recovery media to recover the original system

After you successfully set up the computer, you should create recovery discs or a recovery flash drive using
HP Recovery Manager. You will need these recovery discs or recovery flash drive to perform a system recovery
should the hard drive become corrupted. A system recovery reinstalls the original operating system, and then
configures the settings for the default programs.

What you need to know

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
flash drive or the number of blank DVD discs that will be required.
Use DVD-R, DVD+R, DVD-R DL, DVD+R DL discs or a flash drive. Do not use rewriteable discs such as CD
RW, DVDRW, double-layer DVDRW, and BD-RE (rewritable Blu-ray) discs; they are not compatible
with HP Recovery Manager software.
If your computer does not include an integrated optical drive, you can use an optional external optical
drive (purchased separately) to create recovery discs, or you can obtain recovery discs for your computer
from the HP website. If you use an external optical drive, it must be connected directly to a USB port on
the computer, not to a USB port on an external device, such as a USB hub.
Be sure that the computer is connected to AC power before you begin creating the recovery media.
The creation process can take up to an hour or more. Do not interrupt the creation process.
Store the recovery media in a safe location, separate from the computer.
If necessary, you can exit the program before you have finished creating the recovery media. The next
time you open HP Recovery Manager, you will be prompted to continue the process.

Creating backups 81
 Creating the recovery media

1. Select Start and type recovery in the search field. Select HP Recovery Manager from the list. Allow
the action to continue, if prompted.
2. Click Recovery Media Creation.
3. Follow the on-screen instructions to continue.
To recover, see Recovering the original system using HP Recovery Manager on page 84.

Creating system restore points

A system restore point is a snapshot of certain hard drive contents saved by Windows System Restore at a
specific time. A restore point contains information such as registry settings that Windows uses. Restoring to a
previous restore point allows you to reverse changes that have been made to the system since the restore
point was created.
Restoring to an earlier system restore point does not affect data files saved or emails created since the last
restore point, but it does affect software you may have installed.
For example, if you download a photo from a digital camera and then restore the computer to the state it was
on the previous day, the photo remains on the computer.
However, if you install photo viewing software and then restore your computer to the state it was on the
previous day, the software will be uninstalled, and you won't be able to use it.

What you need to know

If you restore to a restore point and then change your mind, you can undo the restoration.
You should create system restore points:
Before you add or change software or hardware
Periodically, whenever the computer is running normally
System Restore also saves shadow copies of files that have been changed since the last restore point
was created. For more information about using shadow copies to restore, see Help and Support.

Creating a system restore point

1. Select Start > Control Panel > System and Security > System.
2. In the left pane, click System Protection.
3. Click the System Protection tab.
4. Click Create, and follow the on-screen instructions.
To restore, see Restoring to a previous system restore point on page 84.

Backing up system and personal information

Your computer stores information that is important to you, such as files, emails, and photos, and you will
want to keep that information even if you download a virus or the system stops working properly. How
completely you are able to recover your files depends on how recent your backup is. As you add new software
and data files, you should create backups on a regular basis.

82 Chapter 9 Backing up, restoring, and recovering in Windows 7

Tips for a successful backup
Number backup discs before inserting them into the optical drive.
Store personal files in the Documents, Music, Pictures, and Videos libraries, and back up these folders
periodically.
Save customized settings 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 re-enter your preferences.
To create a screen shot:
1. Display the screen you want to save.
2. Copy the screen image:
To copy only the active window, press alt+prt sc.
To copy the entire screen, press prt sc.
3. Open a word-processing document or graphics editing program, and then select Edit > Paste. The
screen image is added to the document.
4. Save and print the document.

What you need to know

You can back up your information to an optional external hard drive, a flash drive, a network drive, or
discs.
Connect the computer to AC power during backups.
Allow enough time for the backup. Depending on files sizes, it may take more than an hour.
Verify the amount of free space on your backup storage device before you back up.
You should back up:
Before adding or changing software or hardware.
Before the computer is repaired or restored.
On a regular schedule to be sure you have recent copies of personal information.
After you add many filesfor example, if you saved videos from a birthday party.
Before using antivirus software to remove a malicious program.
After adding information that is hard to replace, such as pictures, videos, music, project files, or
data records.

Creating a backup using Windows Backup and Restore

Windows allows you to back up files using Windows Backup and Restore. You can select the level you want to
back up, from individual folders to drives. The backups are compressed to save space. To back up:
1. Select Start > Control Panel > System and Security > Backup and Restore.
2. Follow the on-screen instructions to schedule and create a backup.

NOTE: Windows includes the User Account Control feature to improve the security of the computer. You may
be prompted for your permission or password for tasks such as installing software, running utilities, or
changing Windows settings. See Help and Support for more information.

To restore, see Restoring specific files using Windows Backup and Restore on page 84.

Creating backups 83
 Restore and recovery
Restoring to a previous system restore point
Sometimes installing a software program causes your computer or Windows to behave unpredictably. Usually
uninstalling the software fixes the problems. If uninstalling does not fix the problems, you can restore the
computer to a previous system restore point (created at an earlier date and time).
To restore to a previous system restore point, when the computer was running correctly:
1. Select Start > Control Panel > System and Security > System.
2. In the left pane, click System Protection.
3. Click the System Protection tab.
4. Click System Restore, and follow the on-screen instructions.

Restoring specific files

If files are accidentally deleted from the hard disk and they can no longer be restored from the Recycle Bin, or
if files become corrupt, restoring specific files is useful. Restoring specific files is also useful if you ever
choose to recover the original system using HP Recovery Manager. You can only restore specific files that you
have backed up before.

Restoring specific files using Windows Backup and Restore

Windows allows you to restore files that were backed up using Windows Backup and Restore:
1. Select Start > Control Panel > System and Security > Backup and Restore.
2. Follow the on-screen instructions to restore your backup.

NOTE: Windows includes the User Account Control feature to improve the security of the computer. You may
be prompted for your permission or password for tasks such as installing software, running utilities, or
changing Windows settings. See Help and Support for more information.

Recovering the original system using HP Recovery Manager

HP Recovery Manager software allows you to repair or recover the computer to its original factory state.

What you need to know

HP Recovery Manager recovers only software that was installed at the factory. For software not provided
with this computer, you must either download the software from the manufacturer's website or reinstall
the software from the disc provided by the manufacturer.
A system recovery should be used as a final attempt to correct computer issues. If you have not already
tried restore points (see Restoring to a previous system restore point on page 84) and partial restores
(see Restoring specific files on page 84), try them before using HP Recovery Manager to recover your
system.
A system recovery must be performed if the computer hard drive fails or if all attempts to correct any
functional computer issues fail.

84 Chapter 9 Backing up, restoring, and recovering in Windows 7

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 87. For information on the recovery options that are available using the recovery media, see
Using Windows tools on page 88.
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 89.

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.

Creating recovery media and backups 87

 You can use Windows tools to create system restore points and create backups of personal information,
see Using Windows tools on page 88.
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 CDRW, DVDRW, double-layer DVDRW, 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.

13 Statement of memory volatility

The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business
PCs. 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 PC products that use Intel-based or AMD-based system boards contain volatile DDR memory.

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

Questions and answers 107

 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 BIOS Security to Factory Default.
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.

Using HP Sure Start (select models only)

Select computer models are configured 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 configured and enabled. HP Sure Start is configured and already enabled so that most
users can use the HP Sure Start default configuration. The default configuration can be customized by
advanced users.
