Upgrading system 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 32 GB of memory
congured in a high-performing dual-channel mode.
For proper system operation, the DIMMs must adhere to the following specications:
● Industry-standard 288-pin
● Unbuered non-ECC PC4-21300 DDR4-2666 MHz-compliant
● 1.2 volt DDR4-SDRAM memory modules
● CAS latency 15 DDR4 2133 MHz (15-15-15 timing)
● Mandatory JEDEC SPD information
The computer supports the following:
● 512 Mb, 1 Gb, 2 Gb, 4 Gb, and 8 Gb non-ECC memory technologies
● Single-sided and double-sided memory modules
● Memory modules constructed with ×8 and ×16 DDR devices; memory modules constructed with ×4
SDRAM are not supported
NOTE: The system does not operate properly if you install unsupported memory modules.
Installing a memory module
There are two memory 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 ex mode, depending
on how the DIMMs are installed.
NOTE: Single-channel and unbalanced dual-channel memory congurations 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 ex 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 ex 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
14 Chapter 2 Hardware upgrades
DIMM and one 1 GB DIMM, and Channel B should be populated with the other two 1 GB DIMMs. With this
conguration, 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.
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-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
object. For more information, refer to Electrostatic discharge on page 42.
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. See Preparing for disassembly on page 6.

The battery installed on the computer provides power to the real-time clock. When replacing the battery, use
a battery equivalent to the battery originally installed on the computer. The computer has a 3-volt lithium
coin cell battery installed.
WARNING! The computer contains an internal lithium manganese dioxide battery. There is a risk of re 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 re or water.
Replace the battery only with the HP spare designated for this product.
IMPORTANT: 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 briey 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.

B Electrostatic discharge
A discharge of static electricity from a nger 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 exible 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 oors or dissipating oor mats.
● Use conductive eld service tools.
● Use a portable eld 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.

care and shipping preparation
Computer operating guidelines and routine care
Follow these guidelines to properly set up and care for the computer and monitor:
● 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 airow.
● Never restrict the airow 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 airow.
● 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 o 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 nish.
● 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 airow.

Optical drive precautions
Be sure to observe the following guidelines while operating or cleaning the optical drive.
Operation
● Do not move the drive during operation. This may cause it to malfunction during reading.
● Avoid exposing the drive to sudden changes in temperature, as condensation may form inside the unit. If
the temperature suddenly changes while the drive is on, wait at least one hour before you turn o the
power. If you operate the unit immediately, it may malfunction while reading.
● Avoid placing the drive in a location that is subject to high humidity, extreme temperatures, mechanical
vibration, or direct sunlight.
Cleaning
● Clean the panel and controls with a soft, dry cloth or a soft cloth lightly moistened with a mild detergent
solution. Never spray cleaning uids directly on the unit.
● Avoid using any type of solvent, such as alcohol or benzene, which may damage the nish.
Safety
If any object or liquid falls into the drive, immediately unplug the computer and have it checked by an
authorized HP service provider.
Shipping preparation
Follow these suggestions when preparing to ship the computer:
1. Back up the hard drive les to an external storage device. Be sure that the backup media is not exposed
to electrical or magnetic impulses while stored or in transit.
