4 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.
30 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 ex cables with extreme care; these cables
tear easily.
Drive handling
CAUTION: Drives are fragile components that must be handled with care. To prevent damage to the
computer, damage to a drive, or loss of information, observe these precautions:
Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the computer is
o or in Hibernation, turn the computer on, and then shut it down through the operating system.
Before handling a drive, be sure that you are discharged of static electricity. While handling a drive, avoid
touching the connector.
Before removing a diskette drive or optical drive, be sure that a diskette or disc is not in the drive and be sure
that the optical drive tray is closed.
Handle drives on surfaces covered with at least one inch of shock-proof foam.
Avoid dropping drives from any height onto any surface.
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 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.”
Service considerations 31
Grounding guidelines
Electrostatic discharge damage
Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine
the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many
cases, ESD contains enough power to alter device parameters or melt silicon junctions.
A discharge of static electricity from a nger or other conductor can destroy static-sensitive devices or
microcircuitry. Even if the spark is neither felt nor heard, damage may have occurred.
An electronic device exposed to ESD may not be aected at all and can work perfectly throughout a normal
cycle. Or the device may function normally for a while, 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 aects the electrostatic voltage levels generated by dierent
activities.
CAUTION: A product can be degraded by as little as 700 V.
Typical electrostatic voltage levels
Relative humidity
Event 10% 40% 55%
Walking across carpet 35,000 V 15,000 V 7,500 V

32 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 eld service tools, such as cutters, screwdrivers, and vacuums.
●When xtures must directly contact dissipative surfaces, use xtures made only of static-safe materials.
●Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and
Styrofoam.
●Handle ESD-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these
items only at static-free workstations.
●Avoid contact with pins, leads, or circuitry.
●Turn o power and input signals before inserting or removing connectors or test equipment.
Service considerations 33
Equipment guidelines
Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.
●When seated, wear a wrist strap connected to a grounded system. Wrist straps are exible straps with a
minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap
snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips
to connect a wrist strap.
●When standing, use foot straps and a grounded oor mat. Foot straps (heel, toe, or boot straps) can be
used at standing workstations and are compatible with most types of shoes or boots. On conductive
oors or dissipative oor mats, use foot straps on both feet with a minimum of one megohm resistance
between the operator and ground. To be eective, the conductive 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 oor mats with hard ties to the ground
●Field service kits
●Static awareness labels
●Material-handling packages
●Nonconductive plastic bags, tubes, or boxes
●Metal tote boxes
●Electrostatic voltage levels and protective materials
The following table lists the shielding protection provided by antistatic bags and oor mats.
Material Use Voltage protection level
Antistatic plastic Bags 1,500 V
Carbon-loaded plastic Floor mats 7,500 V
Metallized laminate Floor mats 5,000 V

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 specic drivers and applications. See Creating recovery media with HP Recovery Disc
Creator on page 116.
2. Use Windows Backup and Recovery tools to perform the following:
●Back up individual les 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.

124 Chapter 14 Backup and recovery in Windows 10
You can use Windows tools to create system restore points and create backups of personal information,
see Using Windows tools on page 125.
●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 congures
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 ash 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 nd 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 nished creating all of the recovery DVDs.
HP Recovery Manager will nish burning the current DVD. The next time you start HP Recovery
Manager, you will be prompted to continue.

17 Statement of Volatility
The purpose of this document is to provide general information regarding non-volatile memory in industry-
standards 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 o 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 conguration.
Intel-based and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped
from HP assuming that no subsequent modications 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 nite 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.
b. Select the File menu, then Restore Defaults.
c. Select the System Conguration menu, then Restore Security Defaults.
d. 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.
e. 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 conrm and return to the prior menu. Repeat this
procedure if more than one hard drive has a DriveLock password.
f. 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.
g. Select the File menu, then Reset BIOS Security to factory default. Click yes at the warning
message.
h. Select the File menu, then Save Changes and Exit.
i. Reboot the system. If the system has a Trusted Platform Module (TPM) and/or ngerprint 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 Conguration,
141
then AMT Options. Then select Uncongure AMT on next boot. Select Save then Yes. Select the
File menu, and then select Save Changes and Exit. Reboot the system and conrm that you want
to uncongure AMT.
j. If the optional Intel® Anti-Theft Technology (AT) was activated, contact the provider to deactivate
it.
k. If the optional Absolute® Software Computrace® management and tracking service was activated
on the notebook PC, contact the provider to deactivate it.
l. Remove all power and system batteries for at least 24 hours.
2. 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.
b. 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.
b. Select File, then select Restore defaults.
c. Follow the on-screen instructions.
d. Select File, save changes and exit, then press Enter.
2. What kind of conguration data is stored on the DIMM Serial Presence Detect (SPD) memory
module? How would this data be written?
The DIMM SPD memory contains information about the memory module such as size, serial number,
data width, speed/timing, voltage and thermal information. This information is written by the module
manufacturer and stored on an EEPROM. This EEPROM cannot be written to when the memory module is
installed in a PC. Third party tools do exist that can write to the EEPROM when the memory module is
not installed in a PC. There are various third party tools available to read SPD memory.
3. 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.
4. In some PC systems, the Firmware Hub for System BIOS is a ash memory chip so that updates can
be written by the customer. Is this true for these BIOS chips?
Yes, they are ash memory chips.
5. 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 conguration data.
6. Does resetting the CMOS conguration 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 conguration defaults to their factory settings. To return these system
data and conguration defaults to factory settings, refer to question and answer 1 and follow the
instructions for returning the BIOS settings to factory defaults.
