Disassembly preparation and SATA drive
guidelines
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.

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.
Personal grounding methods and equipment
Use the following equipment to prevent static electricity damage to equipment:
16
Chapter 3 Disassembly preparation and SATA drive guidelines
●
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.

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

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 monitor 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 covers or panels removed.
●
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 on the monitor with any type of material.
●
Install or enable power management functions of the operating system or other software, including
sleep states.

Chapter 3 Disassembly preparation and SATA drive guidelines
Tools and software requirements
To service the computer, you need the following:
●
Torx T-15 screwdriver
●
Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
●
Phillips #1 screwdriver
●
Diagnostics software
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
and label the package “Fragile: Handle With Care.”
●
Do not remove hard drives from the shipping package for storage. Keep hard drives in their protective
packaging until they are actually mounted in the CPU.
●
Avoid dropping drives from any height onto any surface.
●
If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard drive while the
computer is on or in standby mode.
●
Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid
touching the connector.
Service considerations
19
●
Do not use excessive force when inserting a drive.
●
Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields
such as monitors or speakers.
Lithium coin cell battery
The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime
of about three years.
See the appropriate removal and replacement chapter for the chassis you are working on in this guide for
instructions on the replacement procedures.
WARNING! This computer contains a lithium battery. There is a risk of fire and chemical burn if the battery is
handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose in water or fire, or
expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the battery.
NOTE: Batteries, battery packs, and accumulators should not be disposed of together with the general
household waste. In order to forward them to recycling or proper disposal, please use the public collection
system or return them to HP, their authorized partners, or their agents.

Chapter 3 Disassembly preparation and SATA drive guidelines
SMART ATA drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal Computers
have built-in drive failure prediction that warns the user or network administrator of an impending failure or
crash of the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as
reallocated sector count, spin retry count, and calibration retry count. If the drive determines that a failure is
imminent, it generates a fault alert.
Cable management
Always follow good cable management practices when working inside the computer.
●
Keep cables away from major heat sources like the heat sink.
●
Do not jam cables on top of memory modules. Printed circuit cards like these are not designed to take
excessive pressure on them.
●
Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the parts
are moved.
●
When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.
●
Do not bend any cable sharply. A sharp bend can break the internal wires.
●
Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
●
Never crease a SATA data cable.
●
Do not rely on components to push cables down into the chassis. Always position the cables to lay
properly by themselves.

2.
Select Network and Internet, and then select Network and Sharing Center.
3.
Select Troubleshoot problems, and then select the network you want to repair.
Current network security codes are unavailable
If you are prompted for a security code (or network key) or a name (SSID) when connecting to a WLAN, the
network is protected by security. The SSID and security code are alphanumeric codes that you enter into your
Sprout to identify your Sprout to the network. You must have the current codes to connect to a secure
network.
●
For a network connected to your personal wireless router, review the router user guide for instructions
on setting up the same codes on both the router and the WLAN device.
●
For a private network, such as a network in an office or at a public Internet chat room, contact the
network administrator to obtain the codes, and then enter the codes when you are prompted to do so.
Some networks change the SSID or network keys used in their routers or access points on a regular basis
to improve security. You must change the corresponding code in your Sprout accordingly.
If you are provided with a new wireless network key and SSID for a network, and if you have previously
connected to that network, follow the steps below to reconnect to the network:
1.
Right-click the network status icon at the far right of the taskbar.
A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs are active,
several will be displayed.
2.
Right-click the network, and then select Properties.
NOTE: If the network you want is not listed, check with the network administrator to be sure that the
router or access point is operating.
3.
Select the Security tab, and then enter the correct wireless encryption data into the Network security
key box.
4.
Select OK to save these settings.
Cannot connect to the wireless router
If you are trying to connect to the wireless router and are unsuccessful, reset the wireless router by removing
power from the router for 10 to 15 seconds.
If Sprout still cannot connect to a WLAN, restart the wireless router. For details, see the router manufacturer's
instructions.

IMPORTANT: For a tablet with a detachable keyboard, connect the tablet to the keyboard base 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 86. For information on the recovery options that are available using the recovery media, see
Using Windows tools on page 87.
●
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 87.
NOTE: If storage is 32 GB or less, Microsoft System Restore is disabled by default.
●
On select products, use the HP Cloud Recovery Download Tool to create a bootable USB drive for your HP
recovery media. Go to https://support.hp.com/us-en/document/c05115630?openCLC=true, select your
country or region, and follow the on-screen instructions.
Creating recovery media and backups
85
Creating HP Recovery media (select products only)
If possible, check for the presence of the Recovery partition and the Windows partition. Right-click 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. You can 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.
You can use Windows tools to create system restore points and create backups of personal information,
see Using Windows tools on page 87.
●
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 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. You can 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.

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: setup password and power-on password. When you establish only a setup 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 setup password will give you access to Computer
Setup.
When both passwords are set, the setup 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 the password for the computer, you can clear that password so you can gain access to the
information on the computer by resetting the password jumper.

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
chapter.

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.
2.
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.
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.
118 Appendix B Statement of memory volatility
6.
How can the BIOS security be reset to factory defaults and data erased?
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.
7.
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.

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