What does it mean when the power button light is flashing red?

A flashing red light on the power button indicates there is a problem with the computer and it is displaying a diagnostic code. You should refer to the Maintenance and Service Guide to interpret the specific code. Under normal operation, the power button light is white when the power is on. (Page 10)

How much RAM can the HP EliteDesk 800 G3 SFF support, and what type does it use?

The computer supports up to 64 GB of memory configured in dual-channel mode. It uses DDR4-SDRAM DIMMs that must be unbuffered non-ECC PC4-19200 DDR4-2400 MHz-compliant, 1.2 volt modules with 288-pin industry-standard configuration. Single-channel and unbalanced dual-channel memory configurations will result in inferior graphics performance. (Page 25)

What precautions should I take before adding or removing memory modules?

You must disconnect the power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules. Voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet, and adding or removing modules while voltage is present may cause irreparable damage to the memory modules or system board. You should also ensure you are discharged of static electricity by briefly touching a grounded metal object before handling memory. (Page 26)

How do I clean the computer case safely?

For 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 and rinse with a damp cloth, and for stubborn stains use isopropyl (rubbing) alcohol, which evaporates quickly and leaves no residue. Always unplug the computer when cleaning with liquids or damp cloths, and never use solvents or flammable solutions. (Page 15)

Which SATA connector should the primary hard drive be connected to on the system board?

The primary Serial ATA (SATA) hard drive must be connected to the dark blue primary SATA connector on the system board labeled SATA0. Secondary hard drives and optical drives should be connected to one of the light blue SATA connectors on the system board, labeled SATA1, SATA2, and SATA3. (Page 32)

What are the operating guidelines to prevent overheating the computer?

Keep the computer on a sturdy, level surface and leave a 10.2-cm (4-inch) clearance on all vented sides and above the monitor to permit required airflow. Never restrict airflow by blocking any vents or air intakes, and never operate the computer with the cover or side panel removed. You should also occasionally clean the air vents and keep liquids away from the computer and keyboard. (Page 14)

What tools do I need to service the HP EliteDesk 800 G3 SFF?

To service the computer, you need a Torx T-15 screwdriver, a Torx T-15 screwdriver with a small diameter shank for certain front bezel removal, a flat-bladed screwdriver, and a Phillips #2 screwdriver. You will also need diagnostics software and a tamper-resistant T-15 wrench. (Page 16)

Is it safe to replace the power supply with a third-party unit?

No — only the power supply provided with the computer, a replacement power supply provided by HP, or a power supply purchased as an accessory from HP should be used with the computer. Using a non-HP power supply may create potential safety issues. Additionally, voltage is always present on the system board when the computer is plugged in, so the power cord must be disconnected before opening the computer. (Page 49)

What should I do after installing a new processor into the system board?

After installing a new processor onto the system board, you must always update the system ROM to ensure that the latest version of the BIOS is being used on the computer. The latest system BIOS can be found at http://www8.hp.com/us/en/support-drivers.html. Additionally, the heat sink must be installed within 24 hours of installing the processor to prevent damage to the processor's solder connections. (Page 53)

How can I prevent overheating of my computer?

Operate the PC on a sturdy surface with at least a 4-inch clearance around all vented sides and above the monitor. Do not block any vents or air intakes and allow for proper airflow through the case (Page 15).

What are common POST error codes?

Refer to Page 109 of the guide which includes specific numeric POST codes along with descriptions and resolutions for each code encountered during system validation (Page 109).

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. Static Shielding Protection Levels Method Voltage Antistatic plastic Carbon-loaded plastic Metallized laminate 1,500 7,500 15,000 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.

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. 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 computer. ● 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. ● 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.

Memory The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM) dual inline memory modules (DIMMs). The memory sockets on the system board are populated with at least one preinstalled memory module. To achieve the maximum memory support, you can populate the system board with up to 64 GB of memory configured in a high-performing dual-channel mode. For proper system operation, the DIMMs must adhere to the following specifications: ● Industry-standard 288-pin ● Unbuffered non-ECC PC4-19200 DDR4-2400 MHz-compliant ● 1.2 volt DDR4-SDRAM memory modules ● CAS latency 17 DDR4 2400 MHz (17-17-17 timing) ● Mandatory JEDEC SPD information The computer supports the following: ● 512 Mb, 1 Gb, 2 Gb, and 4 Gb non-ECC memory technologies ● Single-sided and double-sided memory modules ● Memory modules constructed with x8 and x16 DDR devices; memory modules constructed with x4 SDRAM are not supported

Note:

The system does not operate properly if you install unsupported memory modules. Populating DIMM sockets There are four memory 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 Memory 25

Table 5-2 Computer Setup—Security (continued) Option Description Security Configuration TPM Embedded Security ● TPM Specification Version Displays the current TPM version. ● TPM Device Lets you set the Trusted Platform Module as available or hidden. ● TPM State Select to enable the TPM. ● ClearTPM Select to reset the TPM to an unowned state. After the TPM is cleared, it is also turned off. To temporarily suspend TPM operations, turn the TPM off instead of clearing it.

Caution:

Clearing the TPM resets it to factory defaults and turns it off. You will lose all created keys and data protected by those keys. Utilities Hard Drive Utilities ● Save/Restore MBR of System Hard Drive

Note:

Windows 10 systems are generally not formatted to include an MBR. Instead they use GUID Partition Table (GPT) format, which better supports large hard drives. Enabling this feature will save the Master Boot Record (MBR) of the system hard drive. If the MBR gets changed, the user will be prompted to restore the MBR. Default is disabled. 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.

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. ● Save/Restore GPT of System Hard Drive Enabling this feature will save the GUID Partition Table (GPT) of the system hard drive. If the GPT is subsequently changed, the user is prompted to choose whether to restore GPT. ● DriveLock Allows you to assign or modify a master or user password for hard drives. When this feature is enabled, the user is prompted to provide one of the DriveLock passwords during POST. If neither is successfully entered, the hard drive will remain inaccessible until one of the passwords is successfully provided during a subsequent cold-boot sequence. 72 Chapter 5 Computer Setup (F10) Utility

8 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: administrator password and power-on password. When you establish only an administrator 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 administrator password will give you access to Computer Setup. When both passwords are set, the administrator 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 one or both passwords, you can clear all passwords by powering off the system, opening the cover, temporarily removing the PSWD jumper, and booting once. This will erase the administrator and power-on passwords. You must restore the jumper to create new passwords.

Caution:

Pushing the CMOS button with power removed will reset the BIOS settings to factory defaults. It may be useful to back up the BIOS settings or save them as custom defaults before resetting them in case they are needed later. Back up can be performed in Computer Setup or using the BiosConfigUtility tool available from www.hp.com. See Computer Setup (F10) Utility on page 67 for information on backing up the BIOS settings. Resetting the password jumper

Caution:

Stringent security is a mode where there is no physical bypass of the password function. If enabled, removing the password jumper will be ignored. To enable this mode, change the security setting Clear Password Jumper in Password Policies to Ignore. If you lose or forget the password when in stringent security mode, the system can only be reset by System Management Command. This is a way for HP Service and Support to provide a secure method to access the BIOS and command a password reset for a specifically identified unit under the direction of the owner. This scenario may not be covered under warranty. To prevent needing a customer service event to restore access to the system, record your configured

administrator and power-on passwords in a safe place away from your computer. To disable the power-on or administrator password features, or to clear the power-on or administrator passwords, complete the following steps: Resetting the password jumper 117

You can use Windows tools to create system restore points and create backups of personal information, see Using Windows tools on page 123. ● If your computer does list the Recovery partition and the Windows partition, you can use HP Recovery Manager to create recovery media after you successfully set up the computer. HP Recovery media can be used to perform system recovery if the hard drive becomes corrupted. System recovery reinstalls the original operating system and software programs that were installed at the factory and then configures

the settings for the programs. HP Recovery media can also be used to customize the system or restore the factory image if you replace the hard drive. – Only one set of recovery media can be created. Handle these recovery tools carefully, and keep them in a safe place. – HP Recovery Manager examines the computer and determines the required storage capacity for the media that will be required. – To create recovery discs, your computer must have an optical drive with DVD writer capability, and you must use only high-quality blank DVD-R, DVD+R, DVD-R DL, or DVD+R DL discs. Do not use rewritable discs such as CD±RW, DVD±RW, double-layer DVD±RW, or BD-RE (rewritable Blu-ray) discs; they are not compatible with HP Recovery Manager software. Or, instead, you can use a high- quality blank USB flash drive. – If your computer does not include an integrated optical drive with DVD writer capability, but you would like to create DVD recovery media, you can use an external optical drive (purchased separately) to create recovery discs. If you use an external optical drive, it must be connected directly to a USB port on the computer; the drive cannot be connected to a USB port on an external device, such as a USB hub. If you cannot create DVD media yourself, you can obtain recovery discs for your computer from HP. See the Worldwide Telephone Numbers booklet included with the computer. You can also find contact information on the HP website. Go to http://www.hp.com/ support, select your country or region, and follow the on-screen instructions. – Be sure that the computer is connected to AC power before you begin creating the recovery media. – The creation process can take an hour or more. Do not interrupt the creation process. – If necessary, you can exit the program before you have finished creating all of the recovery DVDs. HP Recovery Manager will finish burning the current DVD. The next time you start HP Recovery Manager, you will be prompted to continue. To create HP Recovery media:

Statement of memory volatility The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business computers. This chapter also provides general instructions for restoring nonvolatile memory that can contain personal data after the system has been powered off and the hard drive has been removed. HP Business computer products that use Intel®-based or AMD®-based system boards contain volatile DDR memory. The amount of nonvolatile memory present in the system depends upon the system configuration.

Intel-based and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped from HP, assuming that no subsequent modifications have been made to the system and assuming that no applications, features, or functionality have been added to or installed on the system. Following system shutdown and removal of all power sources from an HP Business computer system, personal data can remain on volatile system memory (DIMMs) for a finite period of time and will also remain in nonvolatile memory. Use the steps below to remove personal data from the computer, including the nonvolatile memory found in Intel-based and AMD-based system boards.

Note:

If your tablet has a keyboard base, connect to the keyboard base before beginning steps in this chapter. Current BIOS steps

Follow steps (a) through (l) below to restore the nonvolatile memory that can contain personal data.

Restoring or reprogramming nonvolatile memory that does not store personal data is neither necessary nor recommended. a. Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu” message is displayed at the bottom of the screen.

Note:

If the system has a BIOS administrator password, enter the password at the prompt. b. Select Main, select Apply Factory Defaults and Exit, and then select Yes to load defaults. The computer will reboot. c. During the reboot, press esc while the “Press the ESC key for Startup Menu” message is displayed at the bottom of the screen.

Note:

If the system has a BIOS administrator password, enter the password at the prompt. d. Select the Security menu, select Restore Security Settings to Factory Defaults, and then select Yes to restore security level defaults. The computer will reboot. e. During the reboot, press esc while the “Press the ESC key for Startup Menu” message is displayed at the bottom of the screen.

What is a UEFI BIOS, and how is it different from a legacy BIOS?

The Unified Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface between the platform firmware and an operating system (OS). It is a replacement for the older BIOS architecture, but supports much of the legacy BIOS functionality. Like the legacy BIOS, the UEFI BIOS provides an interface to display the system information and configuration settings and to change the configuration of your computer before an OS is loaded. BIOS provides a secure run-time environment that supports a Graphic User Interface (GUI). In this environment, you can use either a pointing device (Touchscreen, TouchPad, pointing stick, or USB mouse) or the keyboard to navigate and make menu and configuration selections. The UEFI BIOS also contains basic system diagnostics. The UEFI BIOS provides functionality beyond that of the legacy BIOS. In addition, the UEFI BIOS works to initialize the computer’s hardware before loading and executing the OS; the run-time environment allows the loading and execution of software programs from storage devices to provide more functionality, such as advanced hardware diagnostics (with the ability to display more detailed system information) and advanced firmware management and recovery software. HP has provided options in Computer Setup (BIOS) to allow you to run in legacy BIOS, if required by the operating system. Examples of this requirement would be if you upgrade or downgrade the OS.

Where does the UEFI BIOS reside?

The UEFI BIOS resides on a flash memory chip. A utility is required to write to the chip.

What kind of configuration data is stored on the DIMM Serial Presence Detect (SPD) memory

module? How would this data be written? The DIMM SPD memory contains information about the memory module, such as size, serial number, data width, speed/timing, voltage, and thermal information. This information is written by the module manufacturer and stored on an EEPROM. This EEPROM cannot be written to when the memory module is installed in a computer. Third-party tools do exist that can write to the EEPROM when the memory module is not installed in a computer. Various third-party tools are available to read SPD memory.

What is meant by “Restore the nonvolatile memory found in Intel-based system boards”?

This message relates to clearing the Real Time Clock (RTC) CMOS memory that contains computer configuration data.

How can the BIOS security be reset to factory defaults and data erased?
