3 Routine care, SATA drive guidelines, and
disassembly preparation
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system
board. You must disconnect the power cord from the power source before opening the computer to prevent
system board or component damage.
Computer operating guidelines and routine care
Follow the guidelines below to properly set up and care for the computer:
●
HP recommends a 17 mm clearance around the vents on the computer head unit and I/O connectivity
base for heat dissipation.
●
Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
●
Never operate the computer with any access panels 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 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 I/O connectivity base.
●
Never cover the vents on the computer or I/O connectivity base 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.
NOTE: For more information on your retail system care and maintenance, refer to “Retail Point of Sales
Systems - Routine Care and Maintenance” available at http://www.hp.com/support.
Touch screen maintenance
Keep your display and touch sensor clean. The touch sensor requires very little maintenance. HP recommends
that you periodically clean the glass touch sensor surface. Be sure to turn o your display before cleaning.
Typically, an isopropyl alcohol and water solution ratio of 50:50 is the best cleaning agent for your touch
sensor. It is important to avoid using any caustic chemicals on the touch sensor. Do not use any vinegar-based
solutions.
14 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths. Always dampen the cloth and then
clean the sensor. Be sure to spray the cleaning liquid onto the cloth, not the sensor, so that drips do not seep
inside the display or stain the bezel.
MSR maintenance
To clean the MSR (magnetic strip reader), swipe a standard cleaning card through the MSR a couple of times.
You can order a standard cleaning card online. You can also put a thin oil-free cloth around a credit card.
Service considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.
Tools and software requirements
To service the computer, you need the following:
●
Torx T-15 screwdriver
●
Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
●
Phillips #2 screwdriver
●
Phillips #1 screwdriver
●
Diagnostics software
●
Tamper-resistant T-10 screwdriver
Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and may
be of dierent lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP
strongly recommends that all screws removed during disassembly be kept with the part that was removed,
then returned to their proper locations.
CAUTION: As each subassembly is removed from the computer, it should be placed away from the work area
to prevent damage.
Cables and connectors
Most cables used throughout the unit are at, exible cables. These cables must be handled with care to
avoid damage. 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 ensure that the cables are routed in such a way that they cannot be caught or snagged by parts
being removed or replaced.
CAUTION: When servicing this computer, ensure that cables are placed in their proper location during the
reassembly process. Improper cable placement can damage the computer.
Lithium coin cell battery
The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime
of about three years.
MSR maintenance 15
See the appropriate removal and replacement chapter for the chassis you are working on in this guide for
instructions on the replacement procedures.
WARNING! This computer contains a lithium battery. There is a risk of re and chemical burn if the battery is
handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose in water or re, or
expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the battery.
NOTE: Batteries, battery packs, and accumulators should not be disposed of together with the general
household waste. In order to forward them to recycling or proper disposal, please use the public collection
system or return them to HP, their authorized partners, or their agents.
Electrostatic discharge information
A sudden discharge of static electricity from your nger 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) may not appear to be aected at all and can work perfectly
throughout a normal cycle. The device may 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.
Generating static
The following table shows that:
●
Dierent activities generate dierent 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 damage to electric
components and accessories.
16 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
●
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 the following equipment to prevent static electricity damage to equipment:
●
Wrist straps are exible straps with a maximum of one-megohm ± 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 t 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 oors or dissipative oor mats, use them on both feet with
a maximum of one-megohm ± 10% resistance between the operator and ground.

Metallized laminate
Grounding the work area
To prevent static damage at the work area, use the following precautions:
●
Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the
work surface and properly grounded tools and equipment.
●
Use static-dissipative mats, foot straps, or air ionizers to give added protection.
●
Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle
them only at static-free work areas.
●
Turn o power and input signals before inserting and removing connectors or test equipment.
●
Use xtures made of static-safe materials when xtures must directly contact dissipative surfaces.
●
Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.
●
Use eld service tools, such as cutters, screwdrivers, and vacuums, that are conductive.

components operate properly.
NOTE: Not all features listed in this guide are available on all computers.
Preparation for disassembly
See Routine care, SATA drive guidelines, and disassembly preparation on page 14 for initial safety procedures.
1. Remove/disengage any security devices that prohibit opening the computer.
2. Shut down the computer properly through the operating system, then turn o any external devices.
3. Disconnect the power cord from the power outlet.
CAUTION: Regardless of the power-on state, voltage is always present on the system board as long as
the system is plugged into an active AC outlet. You must disconnect the power cord and wait
approximately 30 seconds for the power to drain to avoid damage to the internal components of the
computer.
4. Disconnect all cables from the rear I/O connectors.
CAUTION: The screws used in the computer are of dierent thread sizes and lengths; using the wrong screw
in an application may damage the unit.
NOTE: During disassembly, label each cable as you remove it, noting its position and routing. Keep all
screws with the units removed.
Preparation for disassembly 19
Attaching an I/O connectivity base to the Engage One
You can attach an I/O connectivity base to the bottom of the computer’s stand.
1. Prepare the computer for disassembly (Preparation for disassembly on page 19).
2. Remove the cover on the I/O connectivity base by removing the four screws on the underside of the I/O
connectivity base (1), and then lifting the cover o the I/O connectivity base (2).
3. Connect the USB Type-C power cable to the USB Type-C port on the underside of the stand’s column.
20 Chapter 4 Removal and replacement procedures
4. Place the I/O connectivity base onto the bottom of the stand (1), and then tighten the four screws on the
underside of the I/O connectivity base (2) to secure the I/O connectivity base to the stand. Be sure that
the USB Type-C power cable is routed through the gap between the back of the I/O connectivity base and
the stand.
5. To connect and secure the USB Type-C power cable, attach the cable clip to the cable (1), insert the cable
tie into the hole (2) below the USB Type-C port on the hub, and then slide the cable clip onto the cable tie
and connect the cable to the port (3).
