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 aected 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.

12 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation

Generating static

The following table shows that:

●

Dierent activities generate dierent amounts of static electricity.

●

Static electricity increases as humidity decreases.

Removing bubble pack from PCB

Packing PCBs in foam-lined box

These are then multi-packaged inside plastic tubes, trays, or Styrofoam.

NOTE: 700 volts can degrade a product.

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 exible 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 t snugly into the banana plug connector on the grounding mat or workstation.

Electrostatic discharge information 13

●

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, 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 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.

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

●

Never restrict the airow 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 airow.

●

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 airow. 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.

airow.

●

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.

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.

Cleaning the Computer Case

Follow all safety precautions in General cleaning safety precautions on page 15 before cleaning the computer.

Operating guidelines 15

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
limit the airow.

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.

●

If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is
available through many electronic supply outlets.

CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are

improperly removed or installed, the keyboard may not function properly.

Service considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.

Power supply fan

The power supply fan is a variable-speed fan based on the temperature in the power supply.

CAUTION: The cooling fan is always on when the computer is in the “On” mode. The cooling fan is o when

the computer is in “Standby,” “Suspend,” or “O” modes.

You must disconnect the power cord from the power source before opening the computer to prevent system
board or component damage.

Tools and software Requirements

To service the computer, you need the following:

●

Torx T-15 screwdriver

●

Torx T-15 screwdriver with small diameter shank (for certain front bezel removal)

●

Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)

●

Phillips #2 screwdriver

●

Diagnostics software

●

Tamper-resistant T-15 wrench

Screws

The screws used in the computer are not interchangeable. They may have standard or metric threads and may
be of dierent 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.

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.

Service considerations 17

●

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 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.

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 re and chemical burn if the battery is

handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose in water or re, or
expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the battery.

SATA hard drive cables

SATA data cable

Always use an HP approved SATA 6.0 Gb/s cable as it is fully backwards compatible with the SATA 1.5 Gb/s
drives.

Current HP desktop products ship with SATA 6.0 Gb/s hard drives.

SATA data cables are susceptible to damage if overexed. Never crease a SATA data cable and never bend it
tighter than a 30 mm (1.18 in) radius.

The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.

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 expansion cards or 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 at ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.

●

Some at ribbon cables come prefolded. Never change the folds on these cables.

●

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 like the drive cage, power supply, or computer cover to push cables down
into the chassis. Always position the cables to lay properly by themselves.

Memory

Description

16-GB, PC4-2400

8-GB, PC4-2400

4-GB, PC4-2400

2-GB, PC4-2400

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
congured in a high-performing dual-channel mode.

For proper system operation, the DIMMs must adhere to the following specications:

●

●

●

Industry-standard 288-pin

Unbuered 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.

26 Chapter 4 Removal and replacement procedures: Small Form Factor

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 ex mode, depending
on how the DIMMs are installed.

NOTE: Single-channel and unbalanced dual-channel memory congurations 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 ex 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 ex 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
conguration, 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.

IMPORTANT: 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
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 modied

the MBR, may cause the data on the disk to become inaccessible. Only restore a previously saved
MBR if you are condent 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.

NOTE: This selection will only appear when at least one drive that supports the DriveLock feature

is attached to the system.

CAUTION: Be aware that these settings take place immediately. A save is not necessary.

CAUTION: Be sure to document the DriveLock password. Losing a DriveLock password will render a

drive permanently locked.
