Locating internal components
Table 3-1 Internal components
Internal components
(1) Optical disc drive (optional) (3) RTC battery
(2) Memory modules (4) Hard drive
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:
Table 3-2 Memory specications
Component Specication
Memory modules 1.2 volt DDR4-SDRAM memory modules
Compliance Unbuered non-ECC DDR4-2666 MHz SODIMM compliant
Pins Industry-standard 260 pins containing the mandatory Joint Electronic Device
Engineering Council (JEDEC) specication
Support Support CAS latency 19 DDR4 2666 MHz (19-19-19 timing)
Slots 2
Maximum memory 16 GB per memory slot, 32 GB total
Supported 8 Gbit (base) 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 ×8 and ×16 DDR devices are supported; memory modules
constructed with ×4 SDRAM are not supported.
24 Chapter 3 Hardware repair and upgrade
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
Refer to the following table to identify the memory module channel locations.
Table 3-3 Memory module slots
Location System board label Channel
Lower slot SODIMM1 Channel B
Upper slot 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.
Removing and installing memory 25

A Electrostatic discharge
A discharge of static electricity from a nger or other conductor may damage system boards or other static-
sensitive 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.

B 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:
●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.
Computer operating guidelines and routine care 31
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.

Standards and legislation
Standards
Section 508 of the Federal Acquisition Regulation (FAR) standards was created by the US Access Board to
address access to information and communication technology (ICT) for people with physical, sensory, or
cognitive disabilities. The standards contain technical criteria specic to various types of technologies, as well
as performance-based requirements which focus on functional capabilities of covered products. Specic
criteria cover software applications and operating systems, web-based information and applications,
computers, telecommunications products, video and multi-media, and self-contained closed products.
Mandate 376 – EN 301 549
The EN 301 549 standard was created by the European Union within Mandate 376 as the basis for an online
toolkit for public procurement of ICT products. The standard species the functional accessibility
requirements applicable to ICT products and services, together with a description of the test procedures and
evaluation methodology for each accessibility requirement.
Web Content Accessibility Guidelines (WCAG)
Web Content Accessibility Guidelines (WCAG) from the W3C's Web Accessibility Initiative (WAI) helps web
designers and developers create sites that better meet the needs of people with disabilities or age-related
limitations. WCAG advances accessibility across the full range of web content (text, images, audio, and video)
and web applications. WCAG can be precisely tested, is easy to understand and use, and allows web
developers exibility for innovation. WCAG 2.0 has also been approved as ISO/IEC 40500:2012.
WCAG specically addresses barriers to accessing the web experienced by people with visual, auditory,
physical, cognitive, and neurological disabilities, and by older web users with accessibility needs. WCAG 2.0
provides characteristics of accessible content:
●Perceivable (for instance, by addressing text alternatives for images, captions for audio, adaptability of
presentation, and color contrast)
●Operable (by addressing keyboard access, color contrast, timing of input, seizure avoidance, and
navigability)
●Understandable (by addressing readability, predictability, and input assistance)
●Robust (for instance, by addressing compatibility with assistive technologies)
