Removing and installing memory
The memory slots on the system board can be populated with up to two industry-standard small outline dual
inline memory modules (SODIMMs). These memory slots are populated with at least one preinstalled memory
module. A metal shield protects the memory modules.
Memory module specications
For proper system operation, the memory modules must meet the following qualications:
Component Specication
Memory modules 1.2 volt DDR4-SDRAM memory modules
Compliance Unbuered non-ECC PC4-17000 DDR4-2400 MHz-compliant
Pins Industry-standard 260 pins containing the mandatory Joint Electronic Device
Engineering Council (JEDEC) specication
Support Support CAS latency 15 DDR4 2400 MHz (15-15-15 timing)
Slots 2
Maximum Memory 16 GB per memory slot, 32 GB total
Supported 1 Gbit, 2 Gbit, and 4 Gbit non-ECC memory technologies single-sided and double-sided
SODIMMs
Note The system will not operate properly if you install unsupported SODIMM
memory. SODIMMs constructed with x8 and x16 DDR devices are supported; memory
modules constructed with x4 SDRAM are not supported.
30 Chapter 3 Hardware repair and upgrade
Page 37
HP oers upgrade memory for this computer and advises that the consumer purchase it to avoid
compatibility issues with unsupported third-party memory.
Populating memory module slots
The system will automatically operate in single channel mode, dual channel mode, or ex mode, depending
on how the memory modules are installed. Refer to the following table to identify the memory module
channel locations.
Location System board label Channel
Lower Socket SODIMM1 Channel B
Upper Socket SODIMM3 Channel A
The system will automatically operate in single channel mode, dual channel mode, or ex mode, depending
on how the memory modules are installed.
●
The system will operate in single channel mode if the memory module slots are populated in one
channel only.
●
The system will operate in a higher-performing dual channel mode if the memory capacity of the
memory module in Channel A is equal to the memory capacity of the memory module in Channel B.
●
The system will operate in ex mode if the memory capacity of the memory module in Channel A is not
equal to the memory capacity of the memory module 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. 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 memory module in the
system.

A 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
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 in) 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 any of the access panels or any of the expansion card slot covers
removed.
●
Do not stack computers or place computers so near each other that they are subject to each other’s
recirculated 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 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 any 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.
–
Wipe the screen with a soft, clean antistatic cloth. For more diicult cleaning situations, use a
50/50 mix of water and Isopropyl alcohol. Spray the cleaner onto a cloth and use the damp cloth to
gently wipe the screen surface. Never spray the cleaner directly on the screen surface. It may run
behind the bezel and damage the electronics.
–
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.
●
Do not use cleaners that contain any petroleum based materials such as benzene, thinner, or any
volatile substance to clean the screen or cabinet. These chemicals may damage the computer.

Optical disc drive precautions
Be sure to observe the following guidelines while operating or cleaning the optical disc drive.
●
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.
CAUTION: 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.
