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.

The following table shows that:
●
Dierent activities generate dierent amounts of static electricity.
●
Static electricity increases as humidity decreases.

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.
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.

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 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 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 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.
●
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.

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.
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 (DDR4-SDRAM)
dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to two 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 16-GB of memory congured in a high-performing
dual channel mode.
DDR3-SDRAM DIMMs
For proper system operation, the DDR3-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuered non-ECC PC3-12800 DDR3-1600 MHz-compliant
●
1.35 volt or 1.5 volt DDR3/DDR3L-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
●
support CAS latency 11 DDR3 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 x4 SDRAM are not supported
NOTE: The system will not operate properly if you install unsupported DIMMs.
Memory 17
Populating DIMM sockets
There are two DIMM sockets on the system board, with one socket per channel. The sockets are labeled
DIMM1 and DIMM3. Socket DIMM1 operates in memory channel B. Socket DIMM3 operates in memory channel
A.
The system will automatically operate in single channel mode, dual channel mode, or ex mode, depending
on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory congurations will result in inferior graphics
performance.
●
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 memory capacity of the DIMM
in Channel A is equal to the memory capacity of the DIMM in Channel B.
●
The system will operate in ex mode if the memory capacity of the DIMM in Channel A is not equal to the
memory capacity of the DIMM 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 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
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 14).
2. Remove the access panel (Access panel on page 15).
3. Rotate up the internal drive bay housing to access the memory module sockets on the system board.
4. Open both latches of the memory module socket (1), and insert the memory module into the socket (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.
