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.

Generating static

The following table shows that:

●

Dierent activities generate dierent 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 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.

●

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.

Method Voltage

Antistatic plastic

Carbon-loaded plastic

Metallized laminate

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.

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 airow.

●

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.

●

Keep liquids away from the computer and keyboard.

8 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.

Follow all safety precautions in General cleaning safety precautions on page 9 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 airow.

Cleaning the keyboard

Follow all safety precautions in General cleaning safety precautions on page 9 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 9.

When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 9
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 9

●

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 or dirt in conned areas. Allow the parts to air dry before reassembly.

Cleaning the monitor

●

Wipe the monitor screen with a clean cloth moistened with water or with a towelette designed for
cleaning monitors. 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 9.

Cleaning the mouse

Before cleaning the mouse, ensure that the power to the computer is turned o.

●

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

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.

●

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.

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.

Service considerations 11

NOTE: Batteries, battery packs, and accumulators should not be disposed of together with the general

household waste. In order to forward them to recycling or proper disposal, please use the public collection
system or return them to HP, their authorized partners, or their agents.

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.

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

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

The computer comes with double data rate 4 synchronous dynamic random access memory (DDR3-SDRAM)
dual inline memory modules (DIMMs).

SODIMMs

The memory sockets on the system board can be populated with up to two industry-standard SODIMMs.
These memory sockets are populated with at least one preinstalled SODIMM. To achieve the maximum
memory support, you can populate the system board with up to 8 GB of memory.

DDR3-SDRAM SODIMMs

For proper system operation, the SODIMMs must be:

●

industry-standard 204-pin

●

unbuered non-ECC PC3-12800 DDR3-1600 MHz-compliant

●

1.5 volt DDR3-SDRAM SODIMMs or 1.35 volt DDR3L-SDRAM SODIMMs

The DDR3-SDRAM SODIMMs must also:

●

support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)

●

contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specication

In addition, the computer supports:

●

512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies

●

single-sided and double-sided SODIMMS

●

SODIMMs constructed with x8 and x16 devices; SODIMMs constructed with x4 SDRAM are not supported

NOTE: The system will not operate properly if you install unsupported SODIMMs.

Memory 17

Populating SODIMM sockets

There are two SODIMM sockets on the system board, with one socket per channel. The sockets are labeled
XMM1 and XMM2. The XMM1 socket operates in memory channel A. The XMM2 socket operates in memory
channel B.

Item Description System Board Label Socket Color

1 SODIMM1 socket, Channel A XMM1 Black

2 SODIMM2 socket, Channel B XMM3 White

The system will automatically operate in single channel mode, dual channel mode, or ex mode, depending
on how the SODIMMs are installed.

●

The system will operate in single channel mode if the SODIMM sockets are populated in one channel
only.

●

The system will operate in a higher-performing dual channel mode if the memory capacity of the
SODIMM in Channel A is equal to the memory capacity of the SODIMM in Channel B.

●

The system will operate in ex mode if the memory capacity of the SODIMM in Channel A is not equal to
the memory capacity of the SODIMM 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. If one channel will have more memory than the other, the larger amount
should be assigned to channel A.

●

In any mode, the maximum operational speed is determined by the slowest SODIMM in the system.

Replacing SODIMMs

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
object.

When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the
module.

Computer Setup—Advanced

NOTE: Support for specic Computer Setup options may vary depending on the hardware conguration.

Table 5-5 Computer Setup—Advanced (for advanced users)

Option Heading

Power-On Options Allows you to set:

●

●

NOTE: If you turn o power to the computer using the switch on a power strip, you will not be able to

use the suspend/sleep feature or the Remote Management features.

●

Idle Power Savings—Extended/Normal. Allows certain operating systems to decrease the
processors power consumption when the processor is idle. Default is extended.

Runtime Power Management— Enable/Disable. Allows certain operating systems to reduce
processor voltage and frequency when the current software load does not require the full
capabilities of the processor. Default is enabled.

POST messages (enable/disable). Enabling this feature will cause the system to display POST error
messages, which are error messages displayed on the monitor during the Power On Self Test if the
BIOS encounters some kind of problem while starting the PC. A POST error message will only display
on screen if the computer is capable of booting this far. If the POST detects an error before this
point, a beep code is generated instead. Default is disabled.

After Power Loss (o/on/previous state). Default is Power o. Setting this option to:

◦

Power o—causes the computer to remain powered o when power is restored.

◦

Power on—causes the computer to power on automatically as soon as power is restored.

◦

Previous state—causes the computer to power on automatically as soon as power is restored,
if it was on when power was lost.

POST Delay (in seconds). Enabling this feature will add a user-specied delay to the POST process.
This delay is sometimes needed for hard disks on some PCI cards that spin up very slowly, so slowly
that they are not ready to boot by the time POST is nished. The POST delay also gives you more
time to select F10 to enter Computer (F10) Setup. Default is None.

BIOS Power-On Allows you to set the computer to turn on automatically at a time you specify.

Bus Options Allows you to enable or disable:

●

PCI SERR# Generation. Default is enabled.

40 Chapter 5 Computer Setup (F10) Utility

Table 5-5 Computer Setup—Advanced (for advanced users) (continued)

●

PCI VGA Palette Snooping, which sets the VGA palette snooping bit in PCI conguration space; only
needed when more than one graphics controller is installed. Default is disabled.

Device Options Allows you to set:

●

Num Lock State at Power-On (o/on). Default is o.

●

Multi-Processor (enable/disable). Use this option to disable multi-processor support under the OS.
Default is enabled.

●

NIC PXE Option ROM Download. The BIOS contains an embedded NIC option ROM to allow the unit to
boot through the network to a PXE server. This is typically used to download a corporate image to a
hard drive. The NIC option ROM takes up memory space below 1MB commonly referred to as DOS
Compatibility Hole (DCH) space. This space is limited. This F10 option will allow users to disable the
downloading of this embedded NIC option ROM thus giving more DCH space for additional PCI cards
which may need option ROM space. The default will be to have the NIC option-ROM-enabled.

Recovering the Conguration Settings

This method of recovery requires that you rst perform the Save to Removable Media command with the
Computer Setup (F10) Utility before Restore is needed. (See Computer Setup—File on page 36 in the
Computer Setup—File table.)

NOTE: It is recommended that you save any modied computer conguration settings to a USB ash media

device and save the device for possible future use.

To restore the conguration, insert the USB ash media device with the saved conguration and perform the
Restore from Removable Media command with the Computer Setup (F10) Utility. (See Computer Setup—File

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, recongure 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 34.

POST numeric codes and text messages

This section covers those POST errors that have numeric codes associated with them. The section also
includes some text messages that may be encountered during POST.

NOTE: The computer will beep once after a POST text message is displayed on the screen.

8 Password security and resetting BIOS

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 BIOS 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 BiosCongUtility tool
available from www.hp.com.

Resetting the password/BIOS 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 specically identied 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 congured
administrator and power-on passwords in a safe place away from your computer.

Resetting the password jumper will reset BIOS values to factory defaults. It is important to back up the
computer BIOS 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 34 for information on backing up the BIOS
settings.

NOTE: You will receive POST error messages after clearing BIOS and rebooting advising you that

conguration changes have occurred. Use Computer Setup to reset any special system setups along with the
date and time.

On Intel systems with advanced manageability features, resetting the BIOS will also partially unprovision AMT.

To disable the power-on or administrator password features, or to clear the power-on password,
administrator password, or BIOS, complete the following steps:

78 Chapter 8 Password security and resetting BIOS

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

power.

WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to

disconnect the power cord from the wall outlet, and allow the internal system components to cool
before touching.

CAUTION: When the computer is plugged in, the power supply always has voltage applied to the

system board even when the unit is turned o. Failure to disconnect the power cord can result in
damage to the system.

Static electricity can damage the electronic components of the computer or optional equipment. Before
beginning these procedures, ensure that you are discharged of static electricity by briey touching a
grounded metal object. See the Safety & Regulatory Information guide for more information.

3. Remove the access panel.

4. Locate the header and jumper.

NOTE: The password jumper is blue so that it can be easily identied. For assistance locating the

password jumper and other system board components, see the system board components image at

System board callouts on page 25.

5. Remove the jumper from pins 1 and 2.

6. Place the jumper on either pin 1 or 2, but not both, so that it does not get lost.

7. Replace the access panel and reconnect the external equipment.

8. Plug in the computer and turn on power. Allow the operating system to start. This clears the current

passwords and disables the password features.

9. Shut down the computer, unplug the power, and disconnect the external equipment.

10. Remove the access panel.

11. Place the jumper on pins 1 and 2.

12. Replace the access panel.

13. Reconnect the external equipment and plug in the computer.

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.

82 Chapter 10 System backup and recovery

◦

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 high­quality 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
for your computer from HP. See the Worldwide Telephone Numbers booklet included with the

B Statement of Volatility

HP conrms that commercial desktop systems contain DDR3 volatile memory (memory amount depends on
the customer conguration). In addition, the motherboard in the condition originally shipped without
subsequent modication or the addition or installation of any applications, features, or functionality,
contains the following nonvolatile memory: Real Time Clock battery backed-up conguration memory (256
Bytes), DIMM Serial Presence Detect (SPD)
programmable), Serial Peripheral Interface (SPI) ROM for System BIOS (8M Bytes) and Serial Peripheral
Interface (SPI) ROM for System FireBird (Sure Start) (8M Bytes) and Super I/O’s: masked keyboard ROM (overall
2K Bytes). In addition, these units contain a Trusted Platform Module (TPM) that contains 16K Bytes of non­volatile memory for user data. The volatile memory will not hold any user data once power has been removed
for 30 seconds or longer.

To restore the non-volatile memory:

1. Download the latest BIOS (system ROM) from the HP website.

2. Follow the instructions to ash the BIOS that are found on the website.
