3 Routine care, SATA drive guidelines, and
disassembly preparation
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system
board. You must disconnect the power cord from the power source before opening the computer to prevent
system board or component damage.
Electrostatic discharge information
A sudden discharge of static electricity from your nger 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 aected 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.
Generating static
The following table shows how humidity aects the electrostatic voltage levels generated by dierent
activities. A product can be degraded by 700 volts.
●Dierent activities generate dierent amounts of static electricity.
●Static electricity increases as humidity decreases.

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-sensitive 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 containers.
●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:
●Wrist straps are exible straps with a maximum of one-megohm ± 10% resistance in the ground cords.
To provide proper ground, a strap must be worn snugly against bare skin. The ground cord must be
connected to the banana plug connector on the grounding mat or workstation and t snugly into it.
●Heel straps/Toe straps/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 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, observe the following precautions:
●Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the
work surface and use 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 o power and input signals before inserting and removing connectors or test equipment.
●Use xtures made of static-safe materials when xtures must directly contact dissipative surfaces.
●Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.
●Use eld service tools, such as cutters, screwdrivers, and vacuums, that are conductive.
Electrostatic discharge information 13
Recommended materials and equipment

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 airow.
●Never restrict the airow 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 airow.
●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 airow. Be sure to unplug the computer before cleaning the air vents.
●Never operate the computer with the cover or side panel removed.
●Do not stack computers on top of each other or place computers so near each other that they are subject
to each other’s re-circulated or preheated air.
●If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be
provided on the enclosure, and the same operating guidelines listed above will still apply.
●Keep liquids away from the computer and keyboard.
14 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
●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.
Routine care
General cleaning safety precautions
1. Never use solvents or ammable solutions to clean the computer.
2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use
the cloth on the component.
3. Always unplug the computer when cleaning with liquids or damp cloths.
4. Always unplug the computer before cleaning the keyboard, mouse, or air vents.
5. Disconnect the keyboard before cleaning it.
6. Wear safety glasses equipped with side shields when cleaning the keyboard.

Follow all safety precautions in General cleaning safety precautions on page 15 before cleaning the computer.
To clean the computer case, follow the procedures described below:
●To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
●For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping the surface
with a cloth or swab dampened with clear water.
●For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed; alcohol will evaporate quickly
without leaving a residue.
●After cleaning, always wipe the unit with a clean, lint-free cloth.
●Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and
limit the airow.
Cleaning the keyboard
Follow all safety precautions in General cleaning safety precautions on page 15 before cleaning the keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the computer
case on page 15.
When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 15
before following these procedures:
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the
keys.
●Visible debris underneath or between the keys may be removed by vacuuming or shaking.
●Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too
much air pressure can dislodge lubricants applied under the wide keys.
Routine care 15
●If you want to remove a key, use a specially designed key puller to prevent damage to the keys. This tool
is available through many electronics supply outlets.
CAUTION: Never remove a wide, level key (like the space bar) from the keyboard. If these keys are
improperly removed or installed, the keyboard may not function properly.
●Cleaning under a key may be done with a swab moistened with isopropyl alcohol and then squeezed out.
Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any
bers or dirt in conned areas. Allow the parts to air dry before reassembly.
Cleaning the monitor
●Wipe the monitor screen with a towelette designed for cleaning monitors or with a clean cloth
moistened with water. Do not use sprays or aerosols directly on the screen; the liquid may seep into the
housing and damage a component. Never use solvents or ammable liquids on the monitor.
●To clean the monitor body follow the procedures in Cleaning the computer case on page 15.
Cleaning the mouse
Before cleaning the mouse, ensure that the power to the computer is turned o.
●Clean the mouse ball by rst removing the retaining plate and the ball from the housing. Pull out any
debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly.
●To clean the mouse body, follow the procedures in Cleaning the computer case on page 15.
Service considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.
Tools and software requirements
To service the computer, you need the following:
●Torx T-15 screwdriver
●Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
●Phillips #2 screwdriver
●Diagnostics software
Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and may
be of dierent 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 nish. U.S. screws have a silver nish 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.
16 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
Cables and connectors
Most cables used throughout the unit are at, exible 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 computer.
●Avoid dropping drives from any height onto any surface.
●If you are inserting or removing a hard drive, turn o 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.
●Do not use excessive force when inserting a drive.
●Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic elds
such as monitors or speakers.

Memory
Description
Memory modules (PC4-2133-MHz)
16-GB (1 x 16 GB)
16-GB (2 x 8 GB)
4-GB (1 x 4 GB)
The memory module slots on the system board can be populated with up to two industry-standard memory
modules. At least one small outline, dual in-line memory module (SODIMM) is preinstalled. To achieve the
maximum memory support, you can populate the system board with up to 32 GB (16 GB x 2) of memory.
Memory module specications
For proper system operation, the SODIMMs must adhere to the following specications:
●Industry-standard 288-pins
●Unbuered non-ECC PC4-17000 DDR4-2133 MHz-compliant
●1.2 volt DDR4-SDRAM SODIMMs
●Support CAS latency 15 DDR4 2133 MHz (15-15-15 timing)
●Contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specication
The computer supports the following:
●512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
●Single-sided and double-sided SODIMMS
●SODIMMs constructed with x8 and x16 devices
NOTE: To avoid compatibility issues, HP recommends that you use only HP memory modules in this
computer. The system will not operate properly if you install unsupported memory. Memory modules
constructed with x4 SDRAM are not supported.
24 Chapter 4 Removal and replacement procedures – HP Elite Slice base module
Populating memory module slots
There are two memory module slots, one slot per channel. The slots are labeled DIMM1 and DIMM3. The
DIMM1 slot operates in memory channel B. The DIMM3 slot operates in memory channel A.
Item Description System Board Label Slot Color
1 Memory 1 slot, Channel B DIMM1 Black
2 Memory 3 slot, Channel A DIMM3 Black
The system automatically operates in single-channel mode, dual-channel mode, or ex mode, depending on
how the memory modules are installed.
●The system operates in single-channel mode if only one memory module slot is populated.
●The system operates in higher-performing, dual-channel mode if the capacity of the memory modules
in Channel A and Channel B is equal.
●The system operates in ex mode if the capacity of the memory modules in Channel A and Channel B are
not equal. In ex mode, the channel populated with the least amount of memory determines the total
amount of memory that is assigned to dual-channel operation, and the remainder is assigned to single-
channel operation. In ex mode, install the memory module with the larger capacity in the DIMM3 slot
(Channel A).
●In any mode, the maximum operational speed is determined by the slowest memory module in the
system.
Memory 25
Replacing memory modules
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain

7 POST error messages and diagnostic front
panel LEDs and audible codes
This appendix lists the error codes, error messages, and the various indicator light and audible sequences
that you may encounter during Power-On Self-Test (POST) or computer restart, the probable source of the
problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count and non-
error text messages. If a POST error occurs, the screen will display the error message. To manually switch to
the POST Messages Enabled mode during POST, press any key (except F10, F11, or F12). The default mode is
POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are
determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory test.
Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish the
schedule, recongure the computer to the Full Boot Every x Days mode, using Computer Setup.
NOTE: For more information on Computer Setup, see Computer Setup (F10) Utility on page 52.

Interpreting system validation diagnostic front panel LEDs and
audible codes
During the system validation phase that occurs at system startup, the BIOS validates the functionality of the
following subsystems and conditions:
●AC adapter
●System board power
●Processor failure
●BIOS corruption
●Memory failure
●Graphics failure
●System board failure
●BIOS authentication failure
If an error is detected, specic patterns of long and short blinks, accompanied by long and short beeps (where
applicable) are used to identify the error. These patterns will make up a two part code:
92 Chapter 7 POST error messages and diagnostic front panel LEDs and audible codes
●Major – the category of the error
●Minor – the specic error within the category
NOTE: Single beep/blink codes are not used.
Number of long beeps/blinks Error category
1 Not used
2 BIOS
3 Hardware
4 Thermal
5 System board
Patterns of blink/beep codes are determined by using the following parameters:
●1 second pause occurs after the last major blink.
●2 second pause occurs after the last minor blink.
●Beep error code sequences occur for the rst 5 iterations of the pattern and then stop.
●Blink error code sequences continue until the computer is unplugged or the power button is pressed.
NOTE: Not all diagnostic lights and audible codes are available on all models.
The red LED blinks to represent the major error category (long blinks). The white LED blinks to represent the
minor error category (short blinks). For example, ‘3.5’ indicates 3 long red blinks and 5 short white blinks to
communicate the processor is not detected.

8 Password security and resetting CMOS
This computer supports security password features, which can be established through the Computer Setup
Utilities menu.
This computer supports two security password features that are established through the Computer Setup
Utilities menu: administrator password and power-on password. When you establish only an administrator
password, any user can access all the information on the computer except Computer Setup. When you
establish only a power-on password, the power-on password is required to access Computer Setup and any
other information on the computer. When you establish both passwords, only the administrator password will
give you access to Computer Setup.
When both passwords are set, the administrator password can also be used in place of the power-on
password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget one or both passwords, you can clear all passwords by powering o the system, opening the
cover, temporarily removing the PSWD jumper, and booting once. This will erase the administrator and
power-on passwords. You must restore the jumper to create new passwords.
CAUTION: Pushing the CMOS button with power removed will reset the BIOS settings to factory defaults. It
may be useful to back up the BIOS settings or save them as custom defaults before resetting them in case
they are needed later. Back up can be performed in Computer Setup or using the BiosCongUtility tool
available from www.hp.com. See Computer Setup (F10) Utility on page 52 for information on backing up the
BIOS settings.
Resetting the password jumper
CAUTION: Stringent security is a mode where there is no physical bypass of the password function. If
enabled, removing the password jumper will be ignored. To enable this mode, change the security setting
Clear Password Jumper in Password Policies to Ignore.
If you lose or forget the password when in stringent security mode, the system can only be reset by System
Management Command. This is a way for HP Service and Support to provide a secure method to access the
BIOS and command a password reset for a specically identied unit under the direction of the owner. This
scenario may not be covered under warranty.
To prevent needing a customer service event to restore access to the system, record your congured
administrator and power-on passwords in a safe place away from your computer.
To disable the power-on or administrator password features, or to clear the power-on or administrator
passwords, complete the following steps:
Resetting the password jumper 95
1. Shut down the operating system properly, then turn o the computer and any external devices, and
disconnect the power cord from the power outlet.
2. With the power cord disconnected, press the power button again to drain the system of any residual

10 System backup and recovery
Backing up, restoring, and recovering in Windows 10
This section provides information about the following processes. The information in the section is standard
procedure for most products.
●Creating recovery media and backups
●Restoring and recovering your system
For additional information, refer to Help and Support.
▲Type help in the taskbar search box, and then select Help and Support.
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 101. For information on the recovery options that are available using the recovery media, see
What you need to know before you get started on page 103.
●Use Windows tools to create system restore points and create backups of personal information.
For more information, see Using Windows tools on page 102.
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.
●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 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.
You can use Windows tools to create system restore points and create backups of personal information,
see Using Windows tools on page 102.
●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 congures
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.
Backing up, restoring, and recovering in Windows 10 101
○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
