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. The power cord must be disconnected 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 how humidity aects the electrostatic voltage levels generated by dierent
activities. A product can be degraded by 700 volts.

●

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-sensitive parts and assemblies with conductive or approved containers
or packaging.

●

Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.

●

Place items on a grounded surface before removing them from their containers.

●

Always be properly grounded when touching a sensitive component or assembly.

●

Avoid contact with pins, leads, or circuitry.

●

Place reusable electrostatic-sensitive parts from assemblies in protective packaging or
conductive foam.

Personal grounding methods and equipment

Use the following equipment to prevent static electricity damage to equipment:

●

Wrist straps are exible straps with a maximum of one-megohm ± 10% resistance in the ground cords.
To provide proper ground, a strap must be worn snugly against bare skin. The ground cord must be
connected to the banana plug connector on the grounding mat or workstation and t snugly into it.

●

Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with
most types of shoes or boots. On conductive 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, observe the following precautions:

●

Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to
the work surface and use properly grounded tools and equipment.

●

Use static-dissipative mats, foot straps, or air ionizers to give added protection.

●

Handle electrostatic-sensitive components, parts, and assemblies by the case or PCB laminate. Handle
them only at static-free work areas.

●

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.

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 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 the surface
with a cloth or swab dampened with clear water.

●

For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed; alcohol will evaporate quickly
without leaving a residue.

●

After cleaning, always wipe the unit with a clean, lint-free cloth.

●

Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and
limit the 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 want to remove a key, use a specially designed key puller to prevent damage to the keys. This tool
is available through many electronics supply outlets.

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

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

●

Cleaning under a key may be done with a swab moistened with isopropyl alcohol and then squeezed out.
Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any
bers or dirt in conned areas. Allow the parts to air dry before reassembly.

Cleaning the monitor

●

Wipe the monitor screen with a towelette designed for cleaning monitors or with a clean cloth
moistened with water. Do not use sprays or aerosols directly on the screen; the liquid may seep into
the housing and damage a component. Never use solvents or 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.

●

Clean the mouse ball by rst removing the retaining plate and the ball from the housing. Pull out any
debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly.

●

To clean the mouse body, follow the procedures in Cleaning the computer case on page 9.

Service considerations

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

Tools and software requirements

To service the computer, you need the following:

●

Torx T-15 screwdriver

●

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

●

Phillips #2 screwdriver

●

Diagnostics software

Screws

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

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

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.

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

household waste. In order to forward them for recycling or proper disposal, please use the public collection

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: 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 CLR_PSWD jumper, and booting once. This will erase the administrator
and power-on passwords. You must restore the jumper to create new passwords.

The computer’s conguration memory (CMOS) stores information about the computer’s conguration.

The CMOS jumper resets CMOS but does not clear the power-on and setup passwords.

CAUTION: Resetting the CMOS 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. See Computer Setup (F10) Utility on page 19 for information on backing up the BIOS settings.

Resetting CMOS resets BIOS settings to default, but does not clear the passwords or aect any of the other
Security settings. On Intel systems with advanced manageability features, resetting CMOS will also partially
unprovision AMT.

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.

NOTE: You will receive POST error messages after clearing CMOS 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.

CAUTION: 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 19 for
information on backing up the CMOS settings.

about the Windows Backup and Restore tools provided, see Help and Support. To access Help and Support,
select Start > Help and Support.

Recovery after a system failure is only as good as your most recent backup.

1. After you successfully set up the computer, create recovery media. This media can be used to reinstall

the original operating system in cases where the hard drive is corrupted or has been replaced. See

Creating recovery media on page 77.

2. As you add hardware and software programs, create system restore points. A system restore point is a

snapshot of certain hard drive contents saved by Windows System Restore at a specic time. A system
restore point contains information that Windows uses, such as registry settings. Windows creates a
system restore point for you automatically during a Windows update and during other system
maintenance (such as a software update, security scanning, or system diagnostics). You can also
manually create a system restore point at any time. For more information and steps for creating specic
system restore points, see Help and Support. To access Help and Support, select Start > Help and

Support.

3. As you add photos, video, music, and other personal les, create a backup of your personal information.

If les are accidentally deleted from the hard drive and they can no longer be restored from the Recycle
Bin, or if les become corrupted, you can restore the les that you backed up. In case of system failure,
you can use the backup les to restore the contents of your computer. See Backing up your information

on page 79.

NOTE: HP recommends that you print the recovery procedures and save them for later use, in case of

system instability.

Creating recovery media

After you successfully set up the computer, create recovery media. The media can be used to reinstall
the original operating system in cases where the hard drive is corrupted or has been replaced.

There are two types of recovery media. To determine which steps to follow for your computer:

Creating recovery media using HP Recovery Manager (select models only)

●

To create recovery discs, your computer must have a DVD writer. Use DVD+R or DVD-R discs (purchased
separately). The discs you use will depend on the type of optical drive you are using.

NOTE: DVD+R DL, DVD-R DL, or DVD±RW disc are not supported.

●

You have the option of creating a recovery USB ash drive instead, using a high-quality USB drive.

●

If you are creating recovery discs, be sure to use high-quality discs. It is normal for the system to reject
defective discs. You will be prompted to insert a new blank disc to try again.

●

The number of discs in the recovery-disc set depends on your computer model (typically 3 to 6 DVDs).
The Recovery Media Creation program tells you the specic number of blank discs needed to make
the set. If you are using a USB ash drive, the program will tell you the size of the drive required to store
all the data (minimum of 8 GB).

NOTE: The process of creating recovery media is lengthy. You can quit the process at any time. The

next time you initiate the process, it resumes where it left o.

NOTE: Do not use media cards for creating recovery media. The system may not be able to boot up from a

media card and you may not be able to run system recovery.

78 Chapter 10 System backup and recovery

5. Select the USB ash drive from the list of media. The program will let you know how much storage is

required to create the recovery drive. If the USB ash drive does not have enough storage capacity, it will
appear grayed out, and you must replace it with a larger USB ash drive. Click Next.

6. Follow the on-screen instructions. When the process is complete, label the USB ash drive and store it in

a secure place.

Creating recovery discs with HP Recovery Disc Creator (select models only)

HP Recovery Disc Creator is a software program that oers an alternative way to create recovery discs on
select models. After you successfully set up the computer, you can create recovery discs using HP Recovery
Disc Creator. The recovery discs allow you to reinstall your original operating system as well as select drivers
and applications if the hard drive becomes corrupted. HP Recovery Disc Creator creates two kinds of recovery
discs:

●
