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 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.
Generating static
The following table shows how humidity affects the electrostatic voltage levels generated by different
activities. A product can be degraded by 700 volts.
●
●
Different activities generate different amounts of static electricity.
Static electricity increases as humidity decreases.

Electrostatic discharge information 11
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 flexible 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 fit 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 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, 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 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.

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 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.
Operating guidelines 13
●
●
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 flammable 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.

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 airflow.
Cleaning the keyboard
Follow all safety precautions in General cleaning safety precautions on page 14 before cleaning the keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the computer
When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 14
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.
14 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
●
●
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
fibers or dirt in confined 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 flammable liquids on the monitor.
●
Cleaning the mouse
Before cleaning the mouse, ensure that the power to the computer is turned off.
●
●
Clean the mouse ball by first 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.
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 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.
Service considerations 15
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 computer.
●
●
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.
●
●
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.

Memory
Description
16-GB, PC4-17000
8-GB, PC4-17000
4-GB, PC4-17000
2-GB, PC4-17000
The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM)
dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These
memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory
support, you can populate the system board with up to 64 GB of memory configured in a high-performing
dual channel mode.
DDR4-SDRAM DIMMs
For proper system operation, the DIMMs must be:
●
●
●
industry-standard 288-pin
unbuffered non-ECC PC4-17000 DDR4-2133 MHz-compliant
1.2 volt DDR4-SDRAM DIMMs
The DIMMs must also:
●
●
support CAS latency 15 DDR4 2133 MHz (15-15-15 timing)
contain the mandatory JEDEC SPD information
In addition, the computer supports:
●
●
●
512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
single-sided and double-sided DIMMs
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported
NOTE: The system will not operate properly if you install unsupported DIMMs.
Populating DIMM sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled
DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel B. Sockets DIMM3
and DIMM4 operate in memory channel A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending
on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior graphics
performance.
Memory 23
●
●
The system will operate in single channel mode if the DIMM sockets are populated in one channel only.
The system will operate in a higher-performing dual channel mode if the total memory capacity of the
DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The technology and
device width can vary between the channels. For example, if Channel A is populated with two 1 GB
DIMMs and Channel B is populated with one 2 GB DIMM, the system will operate in dual channel mode.
●
The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal
to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated with the
least amount of memory describes the total amount of memory assigned to dual channel and the
remainder is assigned to single channel. For optimal speed, the channels should be balanced so that the
largest amount of memory is spread between the two channels. If one channel will have more memory
than the other, the larger amount should be assigned to Channel A. For example, if you are populating
the sockets with one 2 GB DIMM, and three 1 GB DIMMs, Channel A should be populated with the 2 GB
DIMM and one 1 GB DIMM, and Channel B should be populated with the other two 1 GB DIMMs. With this
configuration, 4 GB will run as dual channel and 1 GB will run as single channel.
●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
Installing DIMMs
CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain
before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to
the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing
memory modules while voltage is present may cause irreparable damage to the memory modules or system
board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important
to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from
having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before beginning
these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal
object.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the
module.
24 Chapter 4 Removal and replacement procedures – Microtower (MT) chassis
3. Open both latches of the memory module socket (1), and insert the memory module into the socket (2).
NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab
on the memory socket.
Populate the black DIMM sockets before the white DIMM sockets.
For maximum performance, populate the sockets so that the memory capacity is spread as equally as
possible between Channel A and Channel B.
4. Push the module down into the socket, ensuring that the module is fully inserted and properly seated.
Make sure the latches are in the closed position (3).
5. Repeat steps 3 and 4 to install any additional modules.
6. Replace the computer access panel.
7. Reconnect the power cord and turn on the computer.
8. Lock any security devices that were disengaged when the access panel was removed.
The computer should automatically recognize the additional memory the next time you turn on the computer.

86 Chapter 6 Troubleshooting without diagnostics
Solving memory problems
If you encounter memory problems, some common causes and solutions are listed in the following table.
CAUTION: Power may still be supplied to the DIMMs when the computer is turned off (depending on the
Management Engine (ME) settings). To avoid damage to the DIMMs or the system board, you must unplug the
computer power cord before attempting to reseat, install, or remove a memory module.
For those systems that support ECC memory, HP does not support mixing ECC and non-ECC memory.
Otherwise, the computer will not boot the operating system.
NOTE: The memory count will be affected by configurations with the Management Engine (ME) enabled. The
ME uses 8MB of system memory in single channel mode or 16MB of memory in dual-channel mode to
download, decompress, and execute the ME firmware for Out-of-Band (OOB), third-party data storage, and
other management functions.
System will not boot or does not function properly after installing additional memory modules.
Cause
Solution
A memory module is not installed in the DIMM1 or XMM1 socket.
Ensure that a memory module is installed in the DIMM1 or XMM1
socket on the system board. This socket must be populated with a
memory module.
Memory module is not the correct type or speed grade for the
system or the new memory module is not seated properly.
Replace module with the correct industry-standard device for the
computer. On some models, ECC and non-ECC memory modules
cannot be mixed.
Out of memory error.
Cause
Solution
You have run out of memory to run the application.
Check the application documentation to determine the memory
requirements.
Memory count during POST is wrong.
Cause
Solution
The memory modules may not be installed correctly.
Check that the memory modules have been installed correctly and
that proper modules are used.
Integrated graphics may use system memory.
No action required.
Insufficient memory error during operation.
Cause
Solution
Too many Terminate and Stay Resident programs (TSRs) are
installed.
Delete any TSRs that you do not need.
You have run out of memory for the application.
Check the memory requirements for the application or add more
memory to the computer.
Solving memory problems 87
Power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps

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: 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.
CAUTION: Pushing the CMOS button will reset CMOS values to factory defaults. It is important to back up the
computer CMOS settings before resetting them in case they are needed later. Back up is easily done through
settings.
Resetting the password jumper
CAUTION: If you enable the stringent security feature in Computer Setup and you forget the setup password
or the power-on password, the computer is inaccessible and can no longer be used.
Enabling the stringent password disables the ability to reset the password by moving the jumper on the
system board.
If you lose or forget the password, the system board must be replaced. This scenario is not covered under
warranty.
To prevent the computer from becoming permanently unusable, record your configured setup password or
power-on password in a safe place away from your computer. Without these passwords, the computer cannot
be unlocked.
To disable the power-on or setup password features, or to clear the power-on or setup passwords, complete
