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 or other conductor can destroy static-sensitive nger
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 at all and can work perfectly aected
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.

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 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 straps with a maximum of one-megohm ± 10% resistance in the ground cords. exible
To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be
connected and snugly into the banana plug connector on the grounding mat or workstation.t
●Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with
most types of shoes or boots. On conductive or dissipative mats, use them on both feet with oors oor
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 power and input signals before inserting and removing connectors or test equipment.o
●Use made of static-safe materials when must directly contact dissipative surfaces.xtures xtures
●Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.
●Use service tools, such as cutters, screwdrivers, and vacuums, that are conductive.eld
12 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
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 into the computer by blocking any vents or air intakes. Do not place the airow
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 Be sure to unplug the computer before cleaning the air vents.airow.
●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 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 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
limit the airow.
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
Case on page 14.
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 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.
●Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed out. Be
careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any
bers conned or dirt in areas. Allow the parts to air dry before reassembly.
Cleaning the monitor

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 cables. These cables must be handled with care to at, exible
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 the computer. Do not remove a hard drive while the o
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.

Memory
Description
8-GB, PC3-12800
4-GB, PC3-12800
2-GB, PC3-12800
The computer comes with low power double data rate 3 synchronous dynamic random access memory
(DDR3L-SDRAM) dual inline memory modules (DIMMs). It also supports standard DDR3-SDRAM 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 32-GB of memory in a high-performing congured
dual channel mode.
DDR3/DDR3L-SDRAM DIMMs
For proper system operation, the DIMMs must be:
●industry-standard 240-pin
●unbuered non-ECC PC3-12800 DDR3/DDR3L-1600 MHz-compliant
●1.5 volt DDR3-SDRAM DIMMs or 1.35 volt DDR3L-SDRAM (Low Power) DIMMs
The DIMMs must also:
●support CAS latency 11 DDR3/DDR3L 1600 MHz (11-11-11 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 p33-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 mode, depending ex
on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory will result in inferior graphics congurations
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 mode if the total memory capacity of the DIMMs in Channel A is not equal ex
to the total memory capacity of the DIMMs in Channel B. In mode, the channel populated with the ex
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
conguration, 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 briey 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.
1. Prepare the computer for disassembly (Preparation for disassembly on page 19).
2. Remove the access panel (Access panel on page 20).
3. Rotate up the internal drive bay housing to access the memory module sockets on the system board.
24 Chapter 4 Removal and replacement procedures – small form factor (SFF) chassis
4. Open both latches of the memory module socket , and insert the memory module into the socket .(1) (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. Refer to Populating DIMM sockets on page 23 for more
information.
5. 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)
6. Repeat steps 4 and 5 to install any additional modules.
7. Replace the access panel.
8. If the computer was on a stand, replace the stand.
9. Reconnect the power cord and turn on the computer.
10. 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.

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, patterns of long and short blinks, accompanied by long and short beeps (where specic
applicable) are used to identify the error. These patterns will make up a two part code:
●Major – the category of the error
●Minor – the error within the categoryspecic

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
Computer Setup. See Computer Setup (F10) Utility on page 63 for information on backing up the CMOS
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 setup password or congured
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
the following steps:
Resetting the password jumper 113

9 HP PC Hardware Diagnostics
To help troubleshoot and diagnose failures, use the UEFI-based hardware diagnostic solution that HP includes
on all products. This tool can even be used if the computer will not boot to the operating system.
Why run HP PC Hardware Diagnostics
The HP PC Hardware Diagnostic tools simplify the process of diagnosing hardware issues and expedite the
support process when issues are found. The tools save time by pinpointing the component that needs to be
replaced.
●Isolate true hardware failures: The diagnostics run outside of the operating system so they eectively
isolate hardware failures from issues that may be caused by the operating system or other software
