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 aected 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.

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 airow 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 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 airow. 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.
●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.

●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 26 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 27.
When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 26
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.
●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 conned 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 27.
Routine care 27
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

●To clean the mouse body, follow the procedures in Cleaning the Computer Case on page 27.
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
●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 dierent 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.
28 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
●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. For more information about preventing electrostatic damage, refer to
Electrostatic discharge information on page 23
●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.

Service considerations 29
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 overexed. 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.
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.

8 System backup and recovery
Backing up, restoring, and recovering in Windows 10
This section provides information about the following processes. The information in the section is standard
procedure for most products.
●Creating recovery media and backups
●Restoring and recovering your system
For additional information, refer to Help and Support.
▲Type help in the taskbar search box, and then select Help and Support.
Creating recovery media and backups
The following methods of creating recovery media and backups are available on select products only. Choose
the available method according to your computer model.
●Use HP Recovery Manager to create HP Recovery media after you successfully set up the computer. This
step creates a backup of the HP Recovery partition on the computer. The backup can be used to reinstall
the original operating system in cases where the hard drive is corrupted or has been replaced. For
information on creating recovery media, see Creating HP Recovery media (select products only)
on page 135. For information on the recovery options that are available using the recovery media, see
What you need to know before you get started on page 137.
●Use Windows tools to create system restore points and create backups of personal information.
For more information, see Using Windows tools on page 136.
NOTE: If storage is 32 GB or less, Microsoft System Restore is disabled by default.
Creating HP Recovery media (select products only)
If possible, check for the presence of the Recovery partition and the Windows partition. From the Start menu,
select File Explorer.
●If your computer does not list the Windows partition and the Recovery partition, you can obtain recovery
media for your system from support. See the Worldwide Telephone Numbers booklet included with the
computer. You can also nd contact information on the HP website. Go to http://www.hp.com/support,
select your country or region, and follow the on-screen instructions.
You can use Windows tools to create system restore points and create backups of personal information,
see Using Windows tools on page 136.
●If your computer does list the Recovery partition and the Windows partition, you can use HP Recovery
Manager to create recovery media after you successfully set up the computer. HP Recovery media can be
used to perform system recovery if the hard drive becomes corrupted. System recovery reinstalls the
original operating system and software programs that were installed at the factory and then congures
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.
Backing up, restoring, and recovering in Windows 10 135
◦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 high-
quality 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

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

10 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 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 BiosCongUtility tool
available from www.hp.com. See Computer Setup (F10) Utility on page 89 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 specically identied 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 congured
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:
156 Chapter 10 Password security and resetting CMOS
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
