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 finger 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 affected 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:
●
Different activities generate different 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 flexible 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 fit 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 floors or dissipative floor 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 off 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 airflow.
●
Never restrict the airflow 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 airflow.
●
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 airflow. 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.
12 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.

Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and
may be of different 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: As each subassembly is removed from the computer, it should be placed away from the work
area to prevent damage.
Cables and connectors
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
14 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
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 off 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 fields
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.

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 overflexed. 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.
●
Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the
parts are moved.
●
When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.
●
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.

Memory
Description
8-GB, PC3-12800, SODIMM
4-GB, PC3-12800, SODIMM
2-GB, PC3-12800, SODIMM
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-SDRAM)
small outline dual inline memory modules (SODIMMs).
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 16 GB of memory.
DDR3L-SDRAM SODIMMs
For proper system operation, the SODIMMs must be:
●
industry-standard 204-pin
●
unbuffered non-ECC PC3-12800 DDR3L-1333 MHz-compliant
●
1.35 volt DDR3L-SDRAM SODIMMs
The DDR3L-SDRAM SODIMMs must also:
●
support CAS latency 11 DDR3L 1333 MHz (11-11-11 timing)
●
contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
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 21
Populating SODIMM sockets
There are two SODIMM sockets on the system board, with one socket per channel. The sockets are labeled
DIMM1 and DIMM2. The DIMM1 socket operates in memory channel B. The DIMM2 socket operates in memory
channel A.
Item Description System Board Label Socket Color
1 SODIMM1 socket, Channel B DIMM1 Black
2 SODIMM2 socket, Channel A DIMM2 Black
The system will automatically operate in single channel mode, dual channel mode, or flex 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 flex 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 flex 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.
22 Chapter 4 Removal and replacement procedures
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 briefly 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.

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

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 configured setup password or
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

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 effectively
isolate hardware failures from issues that may be caused by the operating system or other software
components.
●
Failure ID: When a failure is detected that requires hardware replacement, a 24-digit Failure ID is
generated. This ID can then be provided to the call agent, who will either schedule support or provide
replacement parts.
How to access and run HP PC Hardware Diagnostics
You can run the diagnostics from one of three places, depending on your preference and the health of the
computer.
1. Turn on the computer and press Esc repeatedly until the BIOS Boot Menu appears.
2. Press F2 or select Diagnostics (F2).
Pressing F2 signals the system to search for the diagnostics in the following locations:
a. A connected USB drive (to download the diagnostics tools to a USB drive, see the instructions in
Downloading HP PC Hardware Diagnostics (UEFI) to a USB device on page 91)
b. The hard disk drive
c. A core set of diagnostics in the BIOS (for memory and hard disk drive) that are accessible only if
the USB or hard disk drive versions are not detected
