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.
IMPORTANT: 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) might not appear to be aected at all and can work perfectly
throughout a normal cycle. The device might 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.
IMPORTANT: To prevent damage to the device when you are removing or installing internal components,
observe these precautions:
Keep components in their electrostatic-safe containers until you are ready to install them.
Before touching an electronic component, discharge static electricity by using the guidelines described in this
section.
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
If you remove a component, place it in an electrostatic-safe container.
Generating static electricity
Note the following:
● Dierent activities generate dierent amounts of static electricity.
● Static electricity increases as humidity decreases.

Packing PCBs in foam-lined box
Multiple electric components can be packaged together in plastic tubes, trays, or polystyrene foam.
NOTE: As little as 700 V can degrade a product.
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 static electricity
damage to electronic components.
● 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.

Computer operating guidelines and routine care
Follow these guidelines to properly set up and care for the computer and monitor:
18 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
● 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 in) 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.
● Never operate the computer with any of the access panels or any of the expansion card slot covers
removed.
● Do not stack computers or place computers so near each other that they are subject to each other’s
recirculated 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 with any type of material.
● Install or enable power management functions of the operating system or other software, including
sleep states.
● To clean the computer, rst turn o the computer.
● Disconnect AC power.
● Disconnect all powered external devices.
● 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.
● In addition to the standard care guidelines, to clean the healthcare model, use any of the following
germicidal wipe formulations to clean all exposed surfaces of the computer. Start with the display
and nish with any exible cables. Allow the computer to air-dry before use. (For more
information, see the directions provided by the manufacturer of the wipes.)
IMPORTANT: Do not use cleaners that contain any petroleum based materials such as benzene,
thinner, or any volatile substance to clean the display screen or cabinet. These chemicals may
damage the display.

Service considerations
Keep these considerations in mind during the disassembly and assembly of the computer.
Tools and software requirements
To service the computer, you need the following tools:
● Torx T-15 screwdriver
● Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
● Phillips P1 screwdriver
● Non-conductive, non-marking pry tool
● Diagnostics software
Screws
The screws used in the computer are not interchangeable. They could 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 and then returned to their proper locations.
IMPORTANT: As you remove each subassembly from the computer, place it 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
ensure that the cables are routed so that they cannot be caught or snagged by parts being removed or
replaced.

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.
SATA hard drive cables
SATA data cable
Always use an HP-approved SATA 6.0 Gbps cable as it is fully backwards compatible with the SATA 1.5 Gbps
drives.
Current HP desktop products ship with SATA 6.0 Gbps 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.
● 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.
● 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.
