CAUTION: When servicing the computer, be sure that cables are placed in their proper locations during the
reassembly process. Improper cable placement can damage the computer.
Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat
the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid
bending, twisting, or tearing cables. Be sure that cables are routed in such a way that they cannot be caught
or snagged by parts being removed or replaced. Handle ex cables with extreme care; these cables
tear easily.
Tools required 21
Grounding guidelines
Electrostatic discharge damage
Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine
the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many
cases, ESD contains enough power to alter device parameters or melt silicon junctions.
A discharge of static electricity from a nger or other conductor can destroy static-sensitive devices or
microcircuitry. Even if the spark is neither felt nor heard, damage may have occurred.
An electronic device exposed to ESD may not be aected at all and can work perfectly throughout a normal
cycle. Or the device may function normally for a while, and then degrade in the internal layers, reducing its life
expectancy.
CAUTION: To prevent damage to the computer when you are removing or installing internal components,
observe these precautions:
Keep components in their electrostatic-safe containers until you are ready to install them.
Use nonmagnetic tools.
Before touching an electronic component, discharge static electricity by using the guidelines described in this
section.
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
If you remove a component, place it in an electrostatic-safe container.
The following table shows how humidity aects the electrostatic voltage levels generated by dierent
activities.
CAUTION: A product can be degraded by as little as 700 V.

Packaging and transporting guidelines
Follow these grounding guidelines when packaging and transporting equipment:
●
To avoid hand contact, transport products in static-safe tubes, bags, or boxes.
●
Protect ESD-sensitive parts and assemblies with conductive or approved containers or packaging.
●
Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations.
●
Place items on a grounded surface before removing items from their containers.
●
Always be properly grounded when touching a component or assembly.
●
Store reusable ESD-sensitive parts from assemblies in protective packaging or nonconductive foam.
●
Use transporters and conveyors made of antistatic belts and roller bushings. Be sure that mechanized
equipment used for moving materials is wired to ground and that proper materials are selected to avoid
static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
Workstation guidelines
Follow these grounding workstation guidelines:
●
Cover the workstation with approved static-shielding material.
●
Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and
equipment.
●
Use conductive eld service tools, such as cutters, screwdrivers, and vacuums.
●
When xtures must directly contact dissipative surfaces, use xtures made only of static-safe materials.
●
Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and
Styrofoam.
●
Handle ESD-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these
items only at static-free workstations.
●
Avoid contact with pins, leads, or circuitry.
●
Turn o power and input signals before inserting or removing connectors or test equipment.
Service considerations 23
Equipment guidelines
Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.
●
When seated, wear a wrist strap connected to a grounded system. Wrist straps are exible straps with a
minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap
snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips
to connect a wrist strap.
●
When standing, use foot straps and a grounded oor mat. Foot straps (heel, toe, or 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 foot straps on both feet with a minimum of one megohm resistance
between the operator and ground. To be
the skin.
The following grounding equipment is recommended to prevent electrostatic damage:
●
Antistatic tapes
●
Antistatic smocks, aprons, and sleeve protectors
●
Conductive bins and other assembly or soldering aids
●
Nonconductive foam
●
Conductive tabletop workstations with ground cords of one megohm resistance
●
Static-dissipative tables or oor mats with hard ties to the ground
eective, the conductive strips must be worn in contact with
●
Field service kits
●
Static awareness labels
●
Material-handling packages
●
Nonconductive plastic bags, tubes, or boxes
●
Metal tote boxes
●

Troubleshooting
Basic troubleshooting
If the thin client is experiencing operating problems or will not power on, review the following items.
Table 9-5 Power-on troubleshooting
Issue Procedures
The thin client unit is experiencing operating
problems.
The thin client unit does not power on. 1. Verify that the power supply is good by installing it on a known working unit and
The thin client unit powers on and displays a
splash screen, but does not connect to the
server.
No link or activity on the network RJ-45 LEDs
or the LEDs do not illuminate blinking green
after powering on the thin client unit. (The
network LEDs are located inside the RJ-45
connector on the top, rear panel of the thin
client. Indicator lights are visible when the
connector is installed.)
Ensure that the following connectors are securely plugged into the thin client unit:
Power connector, keyboard, mouse, network RJ-45 connector, display
testing it. If the power supply does not work on the test unit, replace the power
supply.
2. If the unit does not work properly with the replaced power supply, have the unit
serviced.
1. Verify that the network is operating and the network cable is working properly.
2. Verify that the unit is communicating with the server by having the System
Administrator ping the unit from the server:
–
If the thin client pings back, then the signal was accepted and the unit is
working. This indicates a conguration issue.
–
If the thin client does not ping back and the thin client does not connect to
the server, re-image the unit.
1. Verify that the network is not down.
2. Make sure the RJ-45 cable is good by installing the RJ-45 cable onto a known
working device—if a network signal is detected then the cable is good.
3. Verify the power supply is good by replacing the power cable to the unit with a
known working power supply cable and testing it.
4. If network LEDs still do not light and you know the power supply is good, then
re-image the unit.
5. If network LEDs still do not light, run the IP conguration procedure.
6. If network LEDs still do not light, have the unit serviced.
A newly connected unknown USB peripheral
does not respond or USB peripherals
connected prior to the newly connected USB
peripheral will not complete their device
actions.
Video does not display. 1. Verify that the monitor brightness is set to a readable level.
An unknown USB peripheral may be connected and disconnected to a running
platform as long as you do not reboot the system. If problems occur, disconnect the
unknown USB peripheral and reboot the platform.
2. Verify the monitor is good by connecting it to a known working computer and
ensure its front LED turns green (assuming the monitor is Energy Star
compliant). If the monitor is defective, replace it with a working monitor and
repeat testing.
3. Re-image the thin client unit and power on the monitor again.
4. Test the thin client unit on a known working monitor. If the monitor does not
display video, replace the thin client unit.

10 HP ThinUpdate
HP ThinUpdate allows you to download images and add-ons from HP, capture an HP thin client image, and
create bootable USB ash drives for image deployment. You can download it from http://www.hp.com/
support (search for the Thin Client model and click on the Drivers & software section of the support page for
that model. For information on using this software, refer to the Manuals section).
NOTE: HP recommends periodically going to the website to check for application updates.
●
The Image Downloads feature lets you download an image from HP to either local storage or a USB ash
drive. The USB ash drive option creates a bootable USB ash drive that can be used to deploy the image
to other thin clients.
●
The Image Capture feature lets you capture an image from an HP thin client and save it to a USB ash
drive, which can be used to deploy the image to other thin clients.
●
The Add-on Downloads feature lets you download add-ons from HP to either local storage or a USB ash
drive.
●
The USB Drive Management feature lets you do the following:
–
Create a bootable USB ash drive from an image le on local storage
–
Copy a Windows operating system image (.ibr le) from a USB ash drive to local storage
–
Restore a USB ash drive layout
You can use a bootable USB ash drive created with HP ThinUpdate to deploy an HP thin client image to
another HP thin client of the same model with the same operating system.
System requirements
To create a recovery device for the purpose of reashing or restoring the software image on the ash, you will
need the following:
●
One or more HP thin clients.
●
USB ash device in the following size or larger:
–
ThinPro: 8 GB
–
Windows 10 IoT (if using the USB format): 32 GB
NOTE: Optionally, you can use the tool on a Windows computer.
This restore method will not work with all USB ash devices. USB ash devices that do not show up as
removable drive in Windows do not support this restore method. USB ash devices with multiple partitions
generally do not support this restore method. The range of USB ash devices available on the market is
constantly changing. Not all USB ash devices have been tested with the HP Thin Client Imaging Tool.

13 Statement of memory volatility
The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business
PCs. This chapter also provides general instructions for restoring nonvolatile memory that can contain
personal data after the system has been powered o and the solid-state drive has been removed.
HP Business PC products that use Intel®-based or AMD®-based system boards contain volatile DDR memory.
The amount of nonvolatile memory present in the system depends upon the system
based and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped from
HP, assuming that no subsequent modications have been made to the system and assuming that no
applications, features, or functionality have been added to or installed on the system.
Following system shutdown and removal of all power sources from an HP Business PC system, personal data
can remain on volatile system memory (DIMMs) for a nite period of time and will also remain in nonvolatile
memory. Use the steps below to remove personal data from the PC, including the nonvolatile memory found
in Intel-based and AMD-based system boards.
NOTE: If your tablet has a keyboard base, connect to the keyboard base before beginning steps in this
chapter.
