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

There are three supported options: IDE, RAID, and AHCI (default).

CAUTION:

SATA emulation changes may prevent access to existing hard drive data and degrade or corrupt established volumes.

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

RAID - Allows DOS and boot access to RAID volumes. Use this mode with the RAID device driver loaded in the operating system to take advantage of RAID features.

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

NOTE:

The RAID/AHCI device driver must be installed prior to attempting to boot from a RAID/

AHCI volume. If you attempt to boot from a RAID/AHCI volume without the required device driver installed, the system will crash (blue screen). RAID volumes may become corrupted if they are booted to after disabling RAID.

Removable Media Boot

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

Max eSATA Speed

Allows you to choose 1.5 Gbps or 3.0 Gpbs as the maximum eSATA speed. By default, the speed is limited to 1.5 Gbps for maximum reliability.

CAUTION:

Consult your eSATA drive and cable manufacturer before enabling 3.0 Gpbs speed.

Some drive and cable combinations may not run reliably at 3.0 Gpbs.

USB hard drive, USB optical drive, or internal optical drive) 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.

EFI boot sources always have precedence over legacy boot sources.

Legacy Boot Sources: Specify the order in which legacy boot sources (such as a network interface card, internal hard drive, USB optical drive, or internal optical drive) 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:

To drag a device to a preferred place, press Enter . To remove the device from consideration as a bootable device, press F5.

You can use F5 to disable individual boot items, as well as disable EFI boot and/or legacy boot.

NOTE:

Master Boot Record

Security

Enables/disables Master Boot Record (MBR) security.

The MBR contains information needed to successfully boot from a disk and to access the data stored on the disk. Master Boot Record Security may prevent unintentional or malicious changes to the

MBR, such as those caused by some viruses or by the incorrect use of certain disk utilities. It also allows you to recover the "last known good" MBR, should changes to the MBR be detected when the system is restarted.

When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the current bootable disk while in MS-DOS or Windows Safe Mode.

NOTE:

Most operating systems control access to the MBR of the current bootable disk; the BIOS cannot prevent changes that may occur while the operating system is running.

Restores the backup Master Boot Record to the current bootable disk. Default is disabled.

Only appears if all of the following conditions are true:

MBR security is enabled

A backup copy of the MBR has been previously saved

The current bootable disk is the same disk from which the backup copy was saved

CAUTION:

Restoring a previously saved MBR after a disk utility or operating system has modified the MBR, may cause the data on the disk to become inaccessible. Only restore a previously saved

MBR if you are confident that the current bootable disk's MBR has been corrupted or infected with a virus.

POST mode (QuickBoot, Clear Memory, FullBoot, or FullBoot Every x Days).

QuickBoot (default) = Do not clear memory or perform a memory test.

FullBoot = Memory test (count) on cold boot. Clears memory on all boots.

Clear Memory = No memory count on cold boot. Clears memory on all boots.

FullBoot Every x Days = Memory count on 1st cold boot on or after the xth day. No more memory counts until 1st cold boot on or after x days. Clears memory on all boots.

POST messages (enable/disable). Enabling this feature will cause the system to display POST error messages, which are error messages displayed on the monitor during the Power On Self

Test if the BIOS encounters some kind of problem while starting the PC. A POST error message will only display on screen if the computer is capable of booting this far. If the POST detects an error before this point, a beep code is generated instead. Default is disabled.

Press the ESC key for Startup Menu (Enable/Disable). This feature controls the display of the text “Press the ESC key for Startup Menu” during POST. This text does not display on

Windows 8 systems with Fast Boot support. Other text also will not display (for example,

Ownership Tag). Default is enabled.

Option ROM Prompt (enable/disable). Enabling this feature will cause the system to display a message before loading option ROMs. Default is enabled.

After Power Loss (off/on/previous state). Default is Power off. Setting this option to:

Power off—causes the computer to remain powered off when power is restored.

Power on—causes the computer to power on automatically as soon as power is restored.

Previous state—causes the computer to power on automatically as soon as power is restored, if it was on when power was lost.

NOTE:

If you turn off power to the computer using the switch on a power strip, you will not be able to use the suspend/sleep feature or the Remote Management features.

POST Delay (in seconds). Enabling this feature will add a user-specified delay to the POST process. This delay is sometimes needed for hard disks on some PCI cards that spin up very slowly, so slowly that they are not ready to boot by the time POST is finished. The POST delay also gives you more time to select F10 to enter Computer (F10) Setup. Default is None.

Remote Wakeup Boot Source (remote server/local hard drive). Default is Local hard drive.

Factory Recovery Boot Support (Enable/Disable). Provides the ability for the BIOS to redirect the boot to the recovery partition on the user hard drive, if present. Some versions of the recovery software honor the F11 key press even when this feature is disabled by the BIOS.

The value you choose is allocated permanently to graphics and is unavailable to the operating system. For example, if you set this value to 512M on a system with 2 GB of RAM, the system always allocates 512 MB for graphics and the other 1.5 GB for use by the BIOS and operating system. Default is Auto which sets memory allocation to 512

MB.

If you select Force, the UMA Frame Buffer Size option displays, which lets you set the UMA memory size allocation between 32 MB and 1 GB.

Internal Speaker (does not affect external speakers). Default is enabled.

NIC PXE Option ROM Download (PXE, iSCSI, disabled). The BIOS contains an embedded

NIC option ROM to allow the unit to boot through the network to a PXE server. This is typically used to download a corporate image to a hard drive. The NIC option ROM takes up memory space below 1MB commonly referred to as DOS Compatibility Hole (DCH) space. This space is limited. This F10 option will allow users to disable the downloading of this embedded NIC option ROM thus giving more DCH space for additional PCI cards which may need option

ROM space. The default will be to have the NIC option-ROM-enabled. Default is PXE.

SATA RAID Option ROM Download (enable/disable). The BIOS contains an embedded SATA

RAID option ROM for RAID support. This can be temporarily disabled to save DCH space.

Note that with the option ROM disabled, users will be unable to boot to hard drives in the system while running in RAID mode. Default is disabled.

Multi-Processor (enable/disable). Use this option to disable multi-processor support under the

OS. Default is enabled.

Hyper threading (enable/disable). Use this option to disable processor hyper-threading.

Watchdog Timer (enable/disable). Allows you to set amount of time for a operating system and BIOS watchdog alert to be sent if the timers are not deactivated. BIOS watchdog is deactivated by BIOS and would indicate that a halt occurred during execution if the alert is sent to the management console. An operating system alert is deactivated by the operating system image and would indicate that a hang occurred during its initialization. Default is enabled.

Recovering the Configuration Settings

This method of recovery requires that you first perform the Save to Removable Media command with the Computer Setup (F10) Utility before Restore is needed. (See

Computer Setup—File on page 12 in the Computer Setup—File table.)

NOTE:

It is recommended that you save any modified computer configuration settings to a USB flash media device and save the device for possible future use.

To restore the configuration, insert the USB flash media device with the saved configuration and perform the Restore from Removable Media command with the Computer Setup (F10) Utility.

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.

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.

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.

Never use solvents or flammable solutions to clean the computer.

2.

48 Chapter 5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation

Cleaning the Computer Case

Follow all safety precautions in

General Cleaning Safety Precautions on page 48

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 48

before cleaning the keyboard.

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

Cleaning the

Computer Case on page 49

.

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

General Cleaning Safety Precautions on page 48 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.

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 49 .

Routine Care 49

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

Cleaning the Computer Case on page 49 .

Service Considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and assembly of the computer.

Power Supply Fan

The power supply fan is a variable-speed fan based on the temperature in the power supply.

CAUTION:

The cooling fan is always on when the computer is in the “On” mode. The cooling fan is off when the computer is in “Standby,” “Suspend,” or “Off” modes.

You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.

Tools and Software Requirements

To service the computer, you need the following:

Torx T-15 screwdriver (HP screwdriver with bits, PN 161946-001)

Torx T-15 screwdriver with small diameter shank (for certain front bezel removal)

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

Phillips #2 screwdriver

Diagnostics software

HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamperresistant bits (Smart Cover FailSafe Key, PN 166527-002)

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:

Metric screws have a black finish. U.S. screws have a silver finish 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.

50 Chapter 5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation

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 45

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.

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.

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.

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.

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.

52 Chapter 5 Routine Care, SATA Drive Guidelines, and Disassembly Preparation

When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.

Some flat 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.

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.

671613-001

671612-001

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-

SDRAM) dual inline memory modules (DIMMs).

DIMMs

The memory sockets on the system board can be populated with up to four 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 32-GB of memory configured in a highperforming dual channel mode.

DDR3-SDRAM DIMMs

CAUTION:

This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system board, it can cause the physical damage to the DIMM or invoke system malfunction.

For proper system operation, the DDR3-SDRAM DIMMs must be:

● industry-standard 240-pin

● unbuffered non-ECC PC3-PC12800 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, 2-Gbit, 4-Gbit, and 8-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.

60 Chapter 6 Removal and Replacement Procedures Microtower (MT) Chassis

Populating DIMM Sockets

There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.

The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed.

NOTE:

Single channel and unbalanced dual channel memory configurations 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 total memory capacity of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The technology and device width can vary between the channels. For example, if Channel A is populated with two 1-GB DIMMs and Channel B is populated with one 2-GB DIMM, the system will operate in dual channel mode.

The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs 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. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels. If one channel will have more memory than the other, the larger amount should be assigned to Channel

A. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB DIMMs,

Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as dual channel and 1-GB will run as single channel.

In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

Memory 61

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 briefly touching a grounded metal object. For more information, refer to

Electrostatic Discharge Information on page 45

.

When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.

When installing drives, follow these guidelines:

The primary Serial ATA (SATA) hard drive must be connected to the dark blue primary SATA connector on the system board labeled SATA0. If you are adding a second hard drive, connect it to the light blue connector on the system board labeled SATA1.

Connect the first SATA optical drive to the white SATA connector on the system board labeled

SATA2. If you are adding a second optical drive connect it to the black SATA connector on the system board labeled ESATA. If the ESATA connector is already populated, connect the second optical drive to the light blue connector on the system board labeled SATA1.

Connect an optional eSATA adapter cable to the black SATA connector on the system board labeled ESATA.

Connect a media card reader USB cable to the USB connector on the system board labeled

MEDIA.

The power cable for the SATA optical drives is a two-headed cable this is plugged into the system board with the first connector routed to the top 5.25-inch bay and the second connector routed to the bottom 5.25-inch bay.

The power cable for the SATA hard drives is a two-headed cable this is plugged into the system board with the first connector routed to the bottom 3.5-inch bay and the second connector routed to the top 3.5-inch bay.

The system does not support Parallel ATA (PATA) optical drives or PATA hard drives.

You must install guide screws to ensure the drive will line up correctly in the drive cage and lock in place. HP has provided extra guide screws for the drive bays (four 6-32 isolation mounting guide screws and eight M3 metric guide screws), installed on the side of the drive bays. The 6-32 isolation mounting screws are required for a secondary hard drive. All other drives (except the primary hard drive) use M3 metric screws. The HP-supplied metric screws are black and the HPsupplied isolation mounting screws are silver and blue. If you are replacing the primary hard drive, you must remove the four silver and blue 6-32 isolation mounting guide screws from the old hard drive and install them in the new hard drive.

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-

SDRAM) dual inline memory modules (DIMMs).

DIMMs

The memory sockets on the system board can be populated with up to four 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 32-GB of memory configured in a highperforming dual channel mode.

DDR3-SDRAM DIMMs

CAUTION:

This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system board, it can cause the physical damage to the DIMM or invoke system malfunction.

For proper system operation, the DDR3-SDRAM DIMMs must be:

● industry-standard 240-pin

● unbuffered non-ECC PC3-PC12800 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, 2-Gbit, 4-Gbit, and 8-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 105

Populating DIMM Sockets

There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.

The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed.

NOTE:

Single channel and unbalanced dual channel memory configurations 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 total memory capacity of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The technology and device width can vary between the channels. For example, if Channel A is populated with two 1-GB DIMMs and Channel B is populated with one 2-GB DIMM, the system will operate in dual channel mode.

The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs 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. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels. If one channel will have more memory than the other, the larger amount should be assigned to Channel

A. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB DIMMs,

Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as dual channel and 1-GB will run as single channel.

In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

106 Chapter 7 Removal and Replacement Procedures Small Form Factor (SFF) Chassis

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 briefly touching a grounded metal object. For more information, refer to

Electrostatic Discharge Information on page 45 .

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 99 ).

2.

Remove the access panel (

Access Panel on page 100 ).

3.

Figure 7-6

Installing a DIMM

NOTE:

A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket.

Populate the black DIMM sockets before the white DIMM sockets.

For maximum performance, populate the sockets so that the memory capacity is spread as equally

as possible between Channel A and Channel B. Refer to Populating DIMM Sockets on page 106

for more information.

5.

Push the module down into the socket, ensuring that the module is fully inserted and properly seated. Make sure the latches are in the closed position (3).

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 – UEFI

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

- UEFI

To access the UEFI diagnostics:

1.

Restart or turn on the computer and press Esc repeatedly until the BIOS boot menu appears.

2.

Press F2 or select Diagnostics (F2).

10 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.

NOTE:

For more information on Computer Setup, see

Computer Setup (F10) Utility on page 10

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.

11 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 Computer Setup (F10) Utility on page 10 for information on

backing up the CMOS settings.

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.

Resetting the Password Jumper 199

To disable the power-on or setup password features, or to clear the power-on or setup passwords, complete the following steps:

1.

Shut down the operating system properly, then turn off the computer and any external devices, and disconnect the power cord from the power outlet.

2.

With the power cord disconnected, press the power button again to drain the system of any residual power.

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:

When the computer is plugged in, the power supply always has voltage applied to the system board even when the unit is turned off. Failure to disconnect the power cord can result in damage to the system.

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 Safety & Regulatory Information guide for more information.

3.

Remove the access panel.

4.

Locate the header and jumper.

NOTE:

The password jumper is green so that it can be easily identified. For assistance locating the password jumper and other system board components, see the Illustrated Parts & Service Map

(IPSM). The IPSM can be downloaded from http://www.hp.com/support .

5.

Remove the jumper from pins 1 and 2. Place the jumper on either pin 1 or 2, but not both, so that it does not get lost.

6.

Replace the computer cover or access panel.

7.
