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 that:
●
Different activities generate different 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 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:
●
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:
12
●
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.
Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
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
●
Material handling packages
●
Conductive plastic bags
●
Conductive plastic tubes
●
Conductive tote boxes
●
Opaque shielding bags
●
Transparent metallized shielding bags
●
Transparent shielding tubes
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.
6.
Wear safety glasses equipped with side shields when cleaning the keyboard.
Cleaning the Computer Case
Follow all safety precautions in General cleaning safety precautions on page 14 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 it with a cloth
or swab dampened with clear water.
●
For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will evaporate
quickly and not leave 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

Service considerations
15
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 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

Chapter 4 Removal and replacement procedures – Microtower (MT) chassis
Memory
The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM)
dual inline memory modules (DIMMs).
The memory sockets on the system board are populated with at least one preinstalled memory module. 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.
For proper system operation, the DIMMs must adhere to the following specifications:
●
Industry-standard 288-pin
●
Unbuffered non-ECC PC4-19200 DDR4-2400 MHz-compliant
●
1.2 volt DDR4-SDRAM memory modules
●
CAS latency 17 DDR4 2400 MHz (17-17-17 timing)
●
Mandatory JEDEC SPD information
The computer supports the following:
●
512 Mb, 1 Gb, 2 Gb, and 4 Gb non-ECC memory technologies
●
Single-sided and double-sided memory modules
●
Memory modules constructed with x8 and x16 DDR devices; memory modules constructed with x4
SDRAM are not supported
NOTE:
The system does not operate properly if you install unsupported memory modules.
Populating DIMM sockets
There are four memory 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.
●
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
Memory
25
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.
Removing and 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.

Save/Restore MBR of System Hard Drive
NOTE: Windows 10 systems are generally not formatted to include an MBR. Instead they use GUID
Partition Table (GPT) format, which better supports large hard drives.
Enabling this feature will save the Master Boot Record (MBR) of the system hard drive. If the MBR
gets changed, the user will be prompted to restore the MBR. Default is disabled.
The MBR contains information needed to successfully boot from a disk and to access the data stored
on the disk. Master Boot Record Security may prevent unintentional or malicious changes to the
MBR, such as those caused by some viruses or by the incorrect use of certain disk utilities. It also
allows you to recover the "last known good" MBR, should changes to the MBR be detected when the
system is restarted.
NOTE: Most operating systems control access to the MBR of the current bootable disk; the BIOS
cannot prevent changes that may occur while the operating system is running.
Restores the backup Master Boot Record to the current bootable disk. Default is disabled.
Only appears if all of the following conditions are true:
–
MBR security is enabled
–
A backup copy of the MBR has been previously saved
–
The current bootable disk is the same disk from which the backup copy was saved
CAUTION: Restoring a previously saved MBR after a disk utility or operating system has modified
the MBR, may cause the data on the disk to become inaccessible. Only restore a previously saved
MBR if you are confident that the current bootable disk's MBR has been corrupted or infected with a
virus.
●
Save/Restore GPT of System Hard Drive
Enabling this feature will save the GUID Partition Table (GPT) of the system hard drive. If the GPT is
subsequently changed, the user is prompted to choose whether to restore GPT.
●
DriveLock
Allows you to assign or modify a master or user password for hard drives. When this feature is
enabled, the user is prompted to provide one of the DriveLock passwords during POST. If neither is
successfully entered, the hard drive will remain inaccessible until one of the passwords is
successfully provided during a subsequent cold-boot sequence.

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.
110 Chapter 6 Troubleshooting without diagnostics
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.
Power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps

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 nonerror 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, reconfigure 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 75.

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
●

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 off 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 BiosConfigUtility tool
available from www.hp.com. See Computer Setup (F10) Utility on page 75 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 specifically identified 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 configured
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 125
1.
Shut down the operating system properly, then turn off the computer and any external devices, and

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.
6.
How can the BIOS security be reset to factory defaults and data erased?
Questions and answers 149
