Removal and replacement procedures
preliminary requirements

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

Flat-bladed screwdriver

●

Phillips P0 and P1 screwdrivers

●

Torx T8 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
CAUTION: Using excessive force during disassembly and reassembly can damage plastic parts. Use care
when handling the plastic parts. Apply pressure only at the points designated in the maintenance
instructions.

Chapter 4 Removal and replacement procedures preliminary requirements

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.

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 a 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.”

Service considerations

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, and 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.
Use nonmagnetic tools.
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.

Chapter 4 Removal and replacement procedures preliminary requirements

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 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.

Service considerations

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 strips must be worn in contact with
the skin.

The following grounding equipment is recommended to prevent electrostatic damage:
●

Antistatic tapes

●

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

12 Backup and recovery 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

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 116.

Use Windows Backup and Recovery tools to perform the following:
●

Back up individual files and folders

●

Back up your entire hard drive (select models only)

●

Create system repair discs (select models only) with the installed optical drive (select models 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 > 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 117.

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

116 Chapter 12 Backup and recovery in Windows 7

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:
1.

Select Start > All Programs > Productivity and Tools > HP Recovery Disc Creator.

Select Windows disk.

From the drop-down menu, select the drive for burning the recovery media.

Click the Create button to start the burning process.

After the Windows 7 operating system DVD has been created, create the Driver Recovery DVD:
1.

Select Start > All Programs > Productivity and Tools > HP Recovery Disc Creator.

Select Driver disk.

From the drop-down menu, select the drive for burning the recovery media.

Click the Create button to start the burning process.

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 models 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.

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 highquality 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.

15 Backup and Recovery in Ubuntu Linux
Recovery after a system failure is as good as your most recent backup. 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.
Your computer includes tools provided by HP to help you safeguard your information and retrieve it if ever
needed.

Creating backups
1.

Create restore media immediately after you set up the computer. For more information, see Performing
a system recovery on page 131.

As you add files, routinely create a backup of your system and personal information.

Backing up your information
You should back up your computer files on a regular schedule to maintain a current backup. You can manually
back up your information to an optional external drive, a network drive, or discs. Back up your system at the
following times:
●

At regularly scheduled times

●

Before the computer is repaired or restored

●

Before you add or modify hardware or software

To back up your home directory files using Backup Manager Settings:
1.

Select Computer > More Applications > Tools > Backup Manager Settings, and click Backup my home
directory.

Click Storage Destination Location, and then select a location to back up your information.

Click Schedule, and then select a time schedule to perform backups at a regularly scheduled time.
To immediately back up your information, click the Backup Now check box.

Performing a system recovery
Recovery allows you to repair or restore the computer to its original factory state. You can create an HP
Factory Image, using an installed or an external DVD±RW optical drive.
NOTE: Your computer may not come equipped with an internal optical drive. In order to create the HP
Factory Image, you may need to plug in an external optical drive.
CAUTION: Using Recovery completely erases hard drive contents and reformats the hard drive. All files you
have created and any software installed on the computer are permanently removed. The recovery tool
reinstalls the original operating system and HP programs and drivers that were installed at the factory.
Software, drivers, and updates not installed by HP must be manually reinstalled. Personal files must be
restored from a backup.
To restore the computer using the HP Factory Image, you must first create the recovery ISO file and then burn
it to an optical disc.
NOTE:

HP recommends that you create the HP Factory Image in the event of a system failure.

Select Computer > More Applications.

In the left pane, click Tools, and then click Create HP Factory Image in the right pane.

Enter the root password when prompted.

Right-click on the HP_Recovery.iso file and select Open with Brasero.

17 Statement of Volatility
The purpose of this document is to provide general information regarding non-volatile memory in industrystandards based HP Business Notebook PC systems and provide 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 Notebook PC 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 Notebook PC system,
personal data can remain on volatile system memory (DIMMs) for a finite period of time and will also remain
in nonvolatile memory. The steps below will remove personal data from the notebook PC, including the
nonvolatile memory found in Intel-based and AMD-based system boards. Some of these steps are disclosed
in the Maintenance & Service Guides available for HP PC products available on the product support pages at
www.hp.com.
1.

Follow steps (a) through (I) below to restore the nonvolatile memory that can contain personal data.
Restoring or reprogramming nonvolatile memory that does not store personal data is neither necessary
nor recommended.
a.

Enter BIOS (F10) Setup by powering on the system and pressing F10 when prompted near the
bottom of the display, or press the ESC key to display the start up menu, then press F10 . If the
system has a BIOS administrator password, enter the password at the prompt.

Select the File menu, then Restore Defaults.

Select the System Configuration menu, then Restore Security Defaults.

If an asset or ownership tag is set, select the Security menu and scroll down to the Utilities menu.
Select System IDs, and then select the tag that has been set. Press the spacebar once to clear the
tag, then press Enter to return to the prior menu.

If a DriveLock password is set, select the Security menu, scroll down to DriveLock, then select
DriveLock password. Select the desired hard drive. Click Disable protection, enter the existing
master DriveLock password, then press Enter to confirm and return to the prior menu. Repeat this
procedure if more than one hard drive has a DriveLock password.

If an Automatic DriveLock password is set, select the Security menu, scroll down to Automatic
DriveLock, then select the desired hard drive and disable protection. Repeat this procedure if more
than one hard drive has an Automatic DriveLock password.

Select the File menu, then Reset BIOS Security to factory default. Click yes at the warning
message.

Select the File menu, then Save Changes and Exit.

Reboot the system. If the system has a Trusted Platform Module (TPM) and/or fingerprint sensor,
one or two prompts will appear. One to clear the TPM and the other to Reset Fingerprint Sensor;
press F1 to accept or F2 to reject.
If the HP notebook model number ends in a ‘p’ or ‘w’ and includes Intel® Centrino with VProTM,
reboot the PC and enter BIOS Setup by pressing F10 when prompted. Select System Configuration,

141

then AMT Options. Then select Unconfigure AMT on next boot. Select Save then Yes. Select the
File menu, and then select Save Changes and Exit. Reboot the system and confirm that you want
to unconfigure AMT.

If the optional Intel® Anti-Theft Technology (AT) was activated, contact the provider to deactivate
it.

If the optional Absolute® Software Computrace® management and tracking service was activated
on the notebook PC, contact the provider to deactivate it.

Remove all power and system batteries for at least 24 hours.

Remove and retain the storage drive or clear the contents of the drive.
a.

Hard Disk Drive (HDD)
Clear the HDD contents by using the HP Disk Sanitizer® utility or a third party application that,
ideally, is U.S. Department of Defense (DOD) 5220.22-M approved.
To run HP Disk Sanitizer, enter BIOS Setup by powering on the system and pressing F10 when
prompted near the bottom of the display, or press ESC to display the start up menu, then press
F10. Select the Security menu and scroll down to the Utilities menu. Select Disk Sanitizer and
select the desired drive. For a higher level of protection, select Optimum.
NOTE: This process will take a long time, and the amount of time varies based on the hard drive
capacity.

Solid State Drive (SSD)
Clear the SSD contents by using the BIOS Setup Secure Erase command option, or by using a third
party utility designed to erase data from an SSD. To run Secure Erase, enter BIOS Setup by
powering on the system and pressing F10 when prompted near the bottom of the display. Select
the Security menu and scroll down to the Utilities menu. Select Secure Erase and select the
desired hard drive.

Questions and answers
1.

How can the BIOS settings be restored (returned to factory settings)?
a.

Turn on or restart the computer and press F10 when prompted near the bottom of the display.

Select File, then select Restore defaults.

Follow the on-screen instructions.

Select File, save changes and exit, then press Enter.

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. There are various third party tools available to read SPD memory.

Does the “Firmware Hub for System BIOS” contain the BIOS program? Is this chip writable, and if so
how?
The Firmware Hub does contain the BIOS program and is writable. A utility is required to perform the
write function.

In some PC systems, the Firmware Hub for System BIOS is a flash memory chip so that updates can
be written by the customer. Is this true for these BIOS chips?
Yes, they are flash memory chips.

What is meant by “Restore the nonvolatile memory found in Intel-based system boards”?
This relates to clearing the Real Time Clock (RTC) CMOS memory that contains PC configuration data.

Does resetting the CMOS configuration memory return the PC back to factory defaults?
The process of resetting the CMOS will return certain system settings to factory default but will not reset
many of the system data and configuration defaults to their factory settings. To return these system
data and configuration defaults to factory settings, refer to question and answer 1 and follow the
instructions for returning the BIOS settings to factory defaults.
