Configuration

Description

Lists all installed BIOS-controlled storage devices.

When a device is selected, detailed information and options are displayed. The following options may be presented:

Hard Disk: Size, model, firmware, serial number, connector color, SMART, emulation type.

Emulation type has the following choices:

None (prevents BIOS data accesses and disables it as a boot device)

Hard Disk (treated as a hard disk)

Translation Mode (ATA disks only)

Lets you select the translation mode to be used for the device. This enables the BIOS to access disks partitioned and formatted on other systems and may be necessary for users of older versions of

UNIX (e.g., SCO UNIX version 3.2). Options are Automatic, Bit-Shift, LBA Assisted, User, and Off.

User mode allows you to specify the parameters (logical cylinders, heads, and sectors per track) used by the BIOS to translate disk I/O requests (from the operating system or an application) into terms the hard drive can accept. Logical cylinders may not exceed 1024. The number of heads may not exceed 256. The number of sectors per track may not exceed 63. These fields are only visible and changeable when the drive translation mode is set to User.

CAUTION:

Ordinarily, the translation mode selected automatically by the BIOS should not be changed. If the selected translation mode is not compatible with the translation mode that was active when the disk was partitioned and formatted, the data on the disk will be inaccessible.

CD-ROM: Model, firmware, serial number, connector color. No emulation options available.

Boot Order

Removable Media Boot

Enables/disables ability to boot the system from removable media.

SATA Emulation

Allows you to choose how the SATA controller and devices are accessed by the operating system.

There are two supported options: AHCI and IDE.

AHCI (default option) - Allows operating systems with AHCI device drivers loaded to take advantage of more advanced features of the SATA controller.

IDE - This is the most backwards-compatible setting of the two options. Operating systems usually do not require additional driver support in IDE mode.

NOTE:

The AHCI device driver must be installed prior to attempting to boot from an AHCI volume. If you attempt to boot from an AHCI volume without the required device driver installed, the system will crash (blue screen).

Allows you to execute self-tests on ATA hard drives capable of performing the Drive Protection

System (DPS) self-tests.

NOTE:

This selection will only appear when at least one drive capable of performing the DPS selftests is attached to the system.

Allows you to:

● Specify the order in which attached devices (such as a USB flash media device, hard drive, optical drive, or network interface card) are checked for a bootable operating system image.

Each device on the list may be individually excluded from or included for consideration as a bootable operating system source.

Specify the order of attached hard drives. The first hard drive in the order will have priority in the boot sequence and will be recognized as drive C (if any devices are attached).

NOTE:

MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating system has started.

Shortcut to Temporarily Override Boot Order

To boot one time from a device other than the default device specified in Boot Order, restart the computer and press F9 before the computer boots to the operating system. After POST is completed, a list of bootable devices is displayed. Use the arrow keys to select the preferred bootable device and press Enter . The computer then boots from the selected non-default device for this one time.

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.

SATA Hard Drives

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.

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.

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

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.

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

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.

Routine Care

General Cleaning Safety Precautions

1.

Cleaning the Computer Case

Follow all safety precautions in

General Cleaning Safety Precautions on page 29

before cleaning the computer.

To clean the computer case, follow the procedures described below:

● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.

● 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 airflow.

Cleaning the Keyboard

Follow all safety precautions in

General Cleaning Safety Precautions on page 29

before cleaning the keyboard.

To clean the tops of the keys or the keyboard body, follow the procedures described in

Cleaning the

.

When cleaning debris from under the keys, review all rules in

General Cleaning Safety Precautions on page 29 before following these procedures:

Routine Care

29

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 Computer Case on page 29 .

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.

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

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

Electrostatic Discharge Information on page 26

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.

See the appropriate removal and replacement chapter for the chassis you are working on in this guide for instructions on the replacement procedures.

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.
