This information provides general service information for the computer. Adherence to the procedures
and precautions is essential for proper service.
IMPORTANT: When the computer is plugged into an AC power source, DC voltage is always applied to
the system board. You must disconnect the power cord from the power source before opening the
computer to prevent electric shock, 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) might not appear to be affected at all and
can work perfectly throughout a normal cycle. The device might function normally for a while, but it has
been degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.
IMPORTANT: To prevent damage to the device when you are removing or installing internal
components, observe these precautions:
● Keep components in their electrostatic-safe containers until you are ready to install them.
● Before touching an electronic component, discharge static electricity by using the guidelines
described in this section.
● Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
● If you remove a component, place it in an electrostatic-safe container.
Generating static electricity
This table shows how humidity affects the electrostatic voltage levels generated by different activities. A
product can be degraded by 700 V of static electricity.
● 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 static
electricity damage to electronic components.
● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
● Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
● Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
● Place items on a grounded surface before removing them from their container.
● Always be properly grounded when touching a sensitive component or assembly.
● 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 this equipment to prevent static electricity damage to electronic components.
● Wrist straps are flexible straps with a maximum of 1 MΩ ±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 1 MΩ ±10% resistance between the operator and ground.

Chapter 3 Routine care, drive guidelines, and disassembly preparation
● Diagnostics software
Screws
The screws used in the computer are not interchangeable. They could have standard or metric threads
and might be of different lengths.
If you use an incorrect screw during the reassembly process, it can damage the unit. HP strongly
recommends that you keep all screws that you remove during disassembly with the removed part and
then return them to their proper locations.
IMPORTANT: As you remove each subassembly from the computer, place it away from the work area
to prevent damage.
Cables and connectors
Use this information to properly handle cables.
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 route the cables so that they cannot be caught or snagged by parts being removed or
replaced.
IMPORTANT: When servicing this computer, be sure to place cables in their proper location during the
reassembly process. Improper cable placement can damage the computer.
Hard drives
Handle hard drives as delicate, precision components, and avoid all physical shock and vibration. This
advice 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.

The memory sockets on the system board can be populated with up to two industry-standard SODIMMs.
These memory sockets are populated with at least one preinstalled SODIMM. To achieve the maximum
memory support, you can populate the system board with up to 64 GB of memory.
Table 4-3 Memory module specifications
Component Specification
Pins Industry-standard 260-pin containing the mandatory Joint Electronic
Device Engineering Council (JEDEC) specification
Slots 2
Maximum memory 64 GB
Supported 2 Gbit, 4 Gbit, 8 Gbit, and 16 Gbit non-ECC memory technologies single-
sided and double-sided memory modules
NOTE: The system does not operate properly if you install unsupported memory modules. Memory
modules constructed with ×8 and ×16 DDR devices are supported; memory modules constructed with
×4 SDRAM are not supported.
Use this information to correctly populate SODIMM sockets:
There are two SODIMM sockets on the system board, with one socket per channel. The sockets are
labeled DIMM1 and DIMM3. The DIMM1 socket operates in memory channel B. The DIMM3 socket
operates in memory channel A.
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR4-
SDRAM) small outline dual inline memory modules (SODIMMs).
IMPORTANT: 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 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 can cause irreparable damage to the memory
modules or system board.
IMPORTANT: When handling a memory module, be careful not to touch any of the contacts. Doing so
can damage the module.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, use
memory modules with gold-plated metal contacts to prevent corrosion, oxidation, or both, 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, be sure that you are discharged of static electricity by briefly touching a
grounded metal object.
NOTE: System board appearance can vary.
Memory modules (SODIMMs)
27
The system automatically operates in single-channel mode, dual-channel mode, or flex mode, depending
on how the SODIMMs are installed.
● The system operates in single-channel mode if the SODIMM sockets are populated in one channel
only.
● The system operates in a higher-performing dual-channel mode if the memory capacity of the
SODIMM in channel A is equal to the memory capacity of the SODIMM in channel B.
● The system operates in flex mode if the memory capacity of the SODIMM in channel A is not equal
to the memory capacity of the SODIMM 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. If one channel has more memory than the other, assign the
larger amount to channel A.
● In any mode, the maximum operational speed is determined by the slowest SODIMM in the system.
Before replacing the memory modules, follow these steps:
1. Prepare the computer for disassembly (see Preparation for disassembly on page 24).
2. Remove the access panel (see Access panel on page 24).
Replace a memory module:
1. Tilt the fan up and leave it in the upright position.

Solving memory problems
If you encounter memory problems, some common causes and solutions are listed in these tables.
IMPORTANT: Depending on the Management Engine (ME) settings, power can still be supplied to the
DIMMs when the computer is turned off. To avoid damage to the DIMMs or the system board, you must
unplug the computer power cord before attempting to reseat, install, or remove a memory module.
For those systems that support error correction code (ECC) memory, HP does not support mixing ECC
and non-ECC memory. Otherwise, the computer will not boot the operating system.
NOTE: The memory count will be affected by configurations with the ME enabled. The ME uses 8 MB
of system memory in single-channel mode or 16 MB of memory in dual-channel mode to download,
decompress, and execute the ME firmware for Out-of-Band (OOB), third-party data storage, and other
management functions.

a unique identifier used to determine if the device has been previously connected. If the
user previously selected
Always Connect for a device, it is automatically connected to the
PCI-Express bus when attached.
● PCIe and DisplayPort – Secure Connect: Offers enhanced protection for authenticating
a previously connected Thunderbolt device beyond relying on its identifier. The device is
provisioned with a key when initially connected, and on subsequent connections a challenge-
response is implemented to verify the device before it is connected to the PCI-express bus.
● DisplayPort™ only: Permits only USB and DisplayPort functionality to be available via the Type-C
Thunderbolt port. PCI-Express will not be connected from the Thunderbolt device to the internal
PCI-express interface, thus any Thunderbolt device that requires PCI-Express will not function

POST error messages7
This section 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 POST mode selection determines the speed at which the computer loads the operating system and
the extent to which it is tested.
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.
You can enable Full Boot to run every 1 to 30 days on a regularly scheduled basis. To establish the

during POST that might not have an error code or text message associated with them.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the
system board. To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure
to disconnect the power cord from the AC outlet and allow the internal system components to cool
before touching.
During the system validation phase that occurs at system startup, the BIOS validates the functionality of
the following subsystems and conditions:
● AC adapter
● System board power
● Processor failure
● BIOS corruption
● Memory failure

● Graphics failure
● System board failure
● BIOS authentication failure
If an error is detected, specific patterns of long and short blinks, accompanied by long and short beeps
(where applicable) are used to identify the error. These patterns make up a two-part code:
● Major: The category of the error
● Minor: The specific error within the category
NOTE: Single beep and blink codes are not used.
Table 7-2
Beep pattern error identification
Number of long beeps/blinks Error category

5 System board
Patterns of blink/beep codes are determined by using the following parameters:
● 1-second pause occurs after the last major blink.
● 2-second pause occurs after the last minor blink.
● Beep error code sequences occur for the first five iterations of the pattern and then stop.
● Blink error code sequences continue until the computer is unplugged or the power button is
pressed.
NOTE: Not all diagnostic lights and audible codes are available on all models.

For general information regarding nonvolatile memory in HP business computers, and to restore
nonvolatile memory that can contain personal data after the system has been turned off and the hard
drive has been removed, use these instructions.
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, with the following assumptions:
● No subsequent modifications were made to the system.
● No applications, features, or functionality were 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 also
remains in nonvolatile memory. Use the following steps 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

b. Select Main, and then select Apply Factory Defaults and Exit.
c. Follow the on-screen instructions.
d. Select Main, select Save Changes and Exit, and then follow the on-screen instructions.
2. 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 replaces 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 runtime environment that supports a Graphic User Interface (GUI). In this
environment, you can use either a pointing device (touch screen, 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 runtime
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.
3. Where is the UEFI BIOS located?
The UEFI BIOS is located on a flash memory chip. You must use a utility to write to the chip.
4. 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 and timing, voltage, and thermal information. This information is written
by the module manufacturer and stored on an EEPROM. You cannot write to this EEPROM 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.
5. What is meant by “Restore the nonvolatile memory found in Intel-based system boards”?
114
Chapter 11 Statement of memory volatility
This message relates to clearing the Real Time Clock (RTC) CMOS memory that contains computer
configuration data.
6. How can the BIOS security be reset to factory defaults and erase the data?
IMPORTANT: Resetting results in the loss of information.
These steps do not reset Custom Secure Boot Keys. See question and answer 7 for information
about resetting the keys.
a. Turn on or restart the computer, and then quickly press esc.
b. Select Main, and then select Reset Security to Factory Defaults.
c. Follow the on-screen instructions.
d. Select Main, select Save Changes and Exit, and then follow the on-screen instructions.
7. How can the Custom Secure Boot Keys be reset?
Secure Boot is a feature to ensure that only authenticated code can start on a platform. If you
enabled Secure Boot and created Custom Secure Boot Keys, disabling Secure Boot does not clear
the keys. You must also select to clear the Custom Secure Boot Keys. Use the same Secure Boot
access procedure that you used to create the Custom Secure Boot Keys, but select to clear or
delete all Secure Boot Keys.
a. Turn on or restart the computer, and then quickly press esc.
b. Select the Security menu, select Secure Boot Configuration, and then follow the on-screen
instructions.
c. At the Secure Boot Configuration window, select Secure Boot, select Clear Secure Boot Keys,
and then follow the on-screen instructions to continue.
Using HP Sure Start (select products only)
Select computer models are configured with HP Sure Start, a technology that continuously monitors
your computer's BIOS for attacks or corruption.
If the BIOS becomes corrupted or is attacked, HP Sure Start restores the BIOS to its previously safe
state, without user intervention. Those select computer models ship with HP Sure Start configured and
enabled. HP Sure Start is configured and already enabled so that most users can use the HP Sure Start
default configuration. Advanced users can customize the default configuration.

Power cord set requirements12
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 of 100 V
AC to 120 V AC or 220 V AC to 240 V 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
These requirements 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 10 A (7 A Japan only) and a nominal
voltage rating of 125 V AC or 250 V AC, as required by each country’s power system.
3. The diameter of the wire must be a minimum of 0.75 mm
2
or 18 AWG, and the length of the cord must
be between 1.8 m (6 ft) and 3.6 m (12 ft).
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.
Japanese power cord requirements
For use in Japan, use only the power cord received with this product.
IMPORTANT: Do not use the power cord received with this product on any other products.

This system uses an active power factor-corrected power supply. This allows the system to pass the CE mark requirements for
use in the countries of the European Union. The active power factor-corrected power supply also has the added benefit of not
requiring an input-voltage range select switch.
NOTE: Operating temperature is derated 1.0°C per 300 m (1000 ft) to 3000 m (10,000 ft) above sea
level; no direct sustained sunlight. Maximum rate of change is 10°C/Hr. The upper limit might be limited
by the type and number of options installed.
