4 Serial ATA (SATA) Drive Guidelines

and Features

NOTE: HP only supports the use of SATA hard drives on these models of computer. No Parallel

ATA (PATA) drives are supported.

SATA Hard Drives

Serial ATA Hard Drive Characteristics

Number of pins/conductors in data cable 7/7

Number of pins in power cable 15

Maximum data cable length 39.37 in (100 cm)

Data interface voltage differential 400-700 mV

Drive voltages 3.3 V, 5 V, 12 V

Jumpers for configuring drive N/A

Data transfer rate 3.0 Gb/s

SATA Hard Drive Cables

SATA Data Cable

Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA

1.5 Gb/s drives.

Current HP desktop products ship with SATA 3.0 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.

12 Chapter 4 Serial ATA (SATA) Drive Guidelines and Features

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.

Hard Drive Capacities

The combination of the file system and the operating system used in the computer determines the maximum usable size of a drive partition. A drive partition is the largest segment of a drive that may be properly accessed by the operating system. A single hard drive may therefore be subdivided into a number of unique drive partitions in order to make use of all of its space.

Because of the differences in the way that drive sizes are calculated, the size reported by the operating system may differ from that marked on the hard drive or listed in the computer specification. Drive size calculations by drive manufacturers are bytes to the base 10 while calculations by Microsoft are bytes to the base 2.

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.

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.

●

Electrostatic Discharge Information 15

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.

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.

●

Use fixtures made of static-safe materials when fixtures must directly contact dissipative

●

surfaces.

Keep work area free of nonconductive materials such as ordinary plastic assembly aids and

●

Styrofoam.

Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.

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 removed.

●

Do not place computers so near each other that they are subject to each other’s re-circulated or

●

preheated air.

Keep liquids away from the computer and keyboard.

●

Operating Guidelines 17

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.

General Cleaning Safety Precautions

18 Chapter 5 Identifying the Chassis, Routine Care, and Disassembly Preparation

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 fibers or dirt in confined 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 flammable liquids on the monitor.

To clean the monitor body follow the procedures in

●

Cleaning the Mouse

Before cleaning the mouse, ensure that the power to the computer is turned off.

Clean the mouse ball by first 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

●

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 (HP screwdriver with bits, PN 161946-001)

●

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

●

Phillips #2 screwdriver

●

Cleaning the Computer Case on page 18.

● Diagnostics software

● HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamper-

resistant bits (Smart Cover FailSafe Key, PN 166527-002)

Service Considerations 19

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

Most cables used throughout the unit are flat, flexible 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 CPU.

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. For more information about preventing electrostatic damage, refer to

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.

Electrostatic Discharge Information on page 15

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.

20 Chapter 5 Identifying the Chassis, Routine Care, and Disassembly Preparation

WARNING! This computer contains a lithium battery. There is a risk of fire and chemical burn if the

battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose in water or fire, 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 the

general household waste. In order to forward them to recycling or proper disposal, please use the public collection system or return them to HP, their authorized partners, or their agents.

A POST Error Messages

This appendix lists the error codes, error messages, and the various indicator light and audible sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable source of the problem, and steps you can take to resolve the error condition.

POST Message Disabled suppresses most system messages during POST, such as memory count and non-error text messages. If a POST error occurs, the screen will display the error message. To manually switch to the POST Messages Enabled mode during POST, press any key (except F10,

F11, or F12). The default mode is POST Message Disabled.

The speed at which the computer loads the operating system and the extent to which it is tested are determined by the POST mode selection.

Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory test. Full Boot runs all of the ROM-based system tests and takes longer to complete.

Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish the schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.

POST Numeric Codes and Text Messages

This section covers those POST errors that have numeric codes associated with them. The section also includes some text messages that may be encountered during POST.

NOTE: The computer will beep once after a POST text message is displayed on the screen.

Resetting the CMOS Jumper

1. Turn off the computer and any external devices, and disconnect the power cord from the power

outlet. The power must be disconnected from the system to clear CMOS.

2. Disconnect all external equipment connected to the computer.

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 before touching.

CAUTION: Static electricity can damage the electronic components of the computer or optional

equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. See the Hardware Reference Guide for more information.

3. Disassemble the computer until you can gain access to the system board.

CAUTION: Resetting CMOS will restore the computer to factory defaults and will erase any

customized information including passwords, asset numbers, and special settings.

4. Locate the header and jumper labeled CMOS+PW.

NOTE: Be sure you have disconnected the AC power cord from the wall outlet. The CMOS will

not clear if the power cord is connected.

NOTE: For assistance locating the CMOS jumper and other system board components, see

the Illustrated Parts & Service Map (IPSM). You can download the IPSM from

http://www.hp.com/support.

5. Put the jumper on pins 2 and 4. This clears CMOS.

6. Put the jumper back on the original pins.

7. Replace the access panel.

8. Reconnect the external devices.

9. Plug in the computer and turn on power.

NOTE: Use Computer Setup to reset any special system setups along with the date and time.

C Power Cord Set Requirements

The power supplies on some computers have external power switches. The voltage select switch feature on the computer permits it to operate from any line voltage between 100-120 or 220-240 volts AC. Power supplies on those computers that do not have external power switches are equipped with internal switches that sense the incoming voltage and automatically switch to the proper voltage.

The power cord set received with the computer meets the requirements for use in the country where you purchased the equipment.

Power cord sets for use in other countries must meet the requirements of the country where you use the computer.

General Requirements

The requirements listed below are applicable to all countries:

1. The power cord must be approved by an acceptable accredited agency responsible for

evaluation in the country where the power cord set will be installed.

2. The power cord set must have a minimum current capacity of 10A (7A Japan only) and a

nominal voltage rating of 125 or 250 volts AC, as required by each country’s power system.

3. The diameter of the wire must be a minimum of 0.75 mm

must be between 1.8 m (6 feet) and 3.6 m (12 feet).

The power cord should be routed so that it is not likely to be walked on or pinched by items placed upon it or against it. Particular attention should be paid to the plug, electrical outlet, and the point where the cord exits from the product.

WARNING! Do not operate this product with a damaged power cord set. If the power cord set is

damaged in any manner, replace it immediately.
