Installing additional memory
The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM)
dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to two 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 high-performing
dual channel mode.
DDR4-SDRAM DIMMs
For proper system operation, the DIMMs must be:
●
Industry-standard 288-pin
●
Unbuffered non-ECC PC4-17000 DDR4-2133 MHz-compliant
●
1.2 volt DDR4-SDRAM DIMMs
The DIMMs must also:
●
Support CAS latency 15 DDR4 2133 MHz (15-15-15 timing)
●
Contain the mandatory JEDEC SPD information
In addition, the computer supports:
●
512-MB, 1GB, and 2-GB 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.
Populating DIMM sockets
There are two DIMM sockets on the system board, with one socket per channel. The sockets are labeled
DIMM1 and DIMM3. Socket DIMM1 operates in memory channel B. Socket DIMM3 operates 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 memory capacity of the DIMM
in Channel A is equal to the memory capacity of the DIMM in Channel B.
●
The system will operate in flex mode if the memory capacity of the DIMM in Channel A is not equal to the
memory capacity of the DIMM 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
Installing additional memory
11
assigned to single channel. If one channel will have more memory than the other, the larger amount
should be assigned to Channel A.
●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
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 on page 41.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the
module.

Battery replacement
The battery that comes with the computer provides power to the real-time clock. When replacing the battery,
use a battery equivalent to the battery originally installed in the computer. The computer comes with a 3-volt
lithium coin cell battery.
WARNING! The computer contains an internal lithium manganese dioxide battery. There is a risk of fire and
burns if the battery is not handled properly. To reduce the risk of personal injury:
Do not attempt to recharge the battery.
Do not expose to temperatures higher than 60°C (140°F).
Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water.
Replace the battery only with the HP spare designated for this product.
CAUTION: Before replacing the battery, it is important to back up the computer CMOS settings. When the
battery is removed or replaced, the CMOS settings will be cleared.
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.
NOTE: The lifetime of the lithium battery can be extended by plugging the computer into a live AC wall
socket. The lithium battery is only used when the computer is NOT connected to AC power.
HP encourages customers to recycle used electronic hardware, HP original print cartridges, and rechargeable
batteries. For more information about recycling programs, go to http://www.hp.com/recycle.

Electrostatic discharge
A discharge of static electricity from a finger or other conductor may damage system boards or other staticsensitive devices. This type of damage may reduce the life expectancy of the device.
Preventing electrostatic damage
To prevent electrostatic damage, observe the following precautions:
●
Avoid hand contact by transporting and storing products in static-safe containers.
●
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
●
Place parts on a grounded surface before removing them from their containers.
●
Avoid touching pins, leads, or circuitry.
●
Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods
There are several methods for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
●
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist
straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the ground cords. To
provide proper ground, wear the strap snug against the skin.
●
Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet when
standing on conductive floors or dissipating floor mats.
●
Use conductive field service tools.
●
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, contact an HP authorized dealer,
reseller, or service provider.
NOTE: For more information on static electricity, contact an HP authorized dealer, reseller, or service
provider.

Computer operating guidelines, routine
care and shipping preparation
Computer operating guidelines and routine care
Follow these guidelines to properly set up and care for the computer and monitor:
42
●
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.
●
Never operate the computer with the access panel or any of the expansion card slot covers 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.
●
Turn off the computer before you do either of the following:
—
Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products may
discolor or damage the finish.
—
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.
