Working on your thin client

Safety instructions

Prerequisite

Use the following safety guidelines to protect your thin client from potential damage and to ensure your personal safety. Unless otherwise

noted, each procedure included in this document assumes that the following conditions exist:

• You have read the safety information that shipped with your thin client.

• A component can be replaced or, if purchased separately, installed by performing the removal procedure in reverse order.

About this task

WARNING: Disconnect all power sources before opening the thin client cover or panels. After you nish working inside the

computer, replace all covers, panels, and screws before connecting to the electrical outlet.

WARNING: Before working on your thin client, read the safety information that shipped with your thin client. For additional

safety best practices information, see the Regulatory Compliance home page at www.Dell.com/regulatory_compliance.

CAUTION: Many repairs may only be done by a certied service technician. You should only perform troubleshooting and simple

repairs as authorized in your product documentation, or as directed by the online or telephone service and support team.

Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions

that ship with the product.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an

unpainted metal surface at the same time as touching a connector on the back of the thin client.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its

edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.

CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have

connectors with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the

cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a

cable, ensure that both connectors are correctly oriented and aligned.

NOTE: The color of your thin client and certain components may appear dierently than shown in this document.

Before working on your thin client

You must perform the following steps before you work on the thin client:

About this task

NOTE: For more safety best practices, see the Regulatory Compliance home page at www.Dell.com/regulatory_compliance.

Steps

1 Save and close all open les and exit all open applications.

2 Click Start > Power > Shut down to shut down your thin client.

NOTE: For shutdown instructions, see documentation of the respective operating system at www.Dell.com/support.

3 Disconnect your thin client and all the attached devices from their electrical outlets.

4 Disconnect all network cables from your thin client.

5 Disconnect all attached devices and peripherals, such as keyboard, mouse, and external monitor, from your thin client.

6 Working on your thin client

Safety precautions

The safety precautions chapter details the primary steps to be taken before performing any disassembly instructions.

Observe the following safety precautions before you perform any installation or break/x procedures involving disassembly or reassembly:

• Turn o the system and all attached peripherals.

• Disconnect the system and all attached peripherals from AC power.

• Disconnect all network cables, telephone, and telecommunications lines from the system.

• Use an ESD eld service kit when working on thin client to avoid electrostatic discharge (ESD) damage.

• After removing any system component, carefully place the removed component on an anti-static mat.

• Wear shoes with non-conductive rubber soles to reduce the chance of getting electrocuted.

Standby power

Dell products with standby power must be unplugged before you open the case. Systems that incorporate standby power are essentially

powered while turned o. The internal power enables the system to be remotely turned on (wake on LAN) and suspended into a sleep

mode and has other advanced power management features.

Unplugging, pressing and holding the power button for 15 seconds should discharge residual power in the system board. Remove the

battery from the thin client.

Bonding

Bonding is a method for connecting two or more grounding conductors to the same electrical potential. This is done through the use of a

eld service electrostatic discharge (ESD) kit. When connecting a bonding wire, ensure that it is connected to bare metal and never to a

painted or non-metal surface. The anti-static wrist strap should be secure and in full contact with your skin, and ensure that you remove all

jewelry such as watches, bracelets, or rings prior to bonding yourself and the equipment.

Electrostatic discharge—ESD protection

ESD is a major concern when you handle electronic components, especially sensitive components such as expansion cards, processors,

memory DIMMs, and system boards. Very slight charges can damage circuits in ways that may not be obvious, such as intermittent

problems or a shortened product life span. As the industry pushes for lower power requirements and increased density, ESD protection is an

increasing concern.

Due to the increased density of semiconductors used in recent Dell products, the sensitivity to static damage is now higher than in previous

Dell products. For this reason, some previously approved methods of handling parts are no longer applicable.

Two recognized types of ESD damage are catastrophic and intermittent failures.

•Catastrophic—Catastrophic failures represent approximately 20 percent of ESD-related failures. The damage causes an immediate and

complete loss of device functionality. An example of catastrophic failure is a memory DIMM that has received a static shock and

immediately generates a "No POST/No Video" symptom with a beep code emitted for missing or nonfunctional memory.

•Intermittent—Intermittent failures represent approximately 80 percent of ESD-related failures. The high rate of intermittent failures

means that most of the time when damage occurs, it is not immediately recognizable. The DIMM receives a static shock, but the

tracing is merely weakened and does not immediately produce outward symptoms related to the damage. The weakened trace may

take weeks or months to melt, and in the meantime may cause degradation of memory integrity, intermittent memory errors, etc.

The more dicult type of damage to recognize and troubleshoot is the intermittent (also called latent or "walking wounded") failure.

Perform the following steps to prevent ESD damage:

• Use a wired anti-static wrist strap that is properly grounded. The use of wireless anti-static wrist straps is no longer allowed because

they do not provide adequate protection. Touching the chassis before handling parts does not ensure adequate ESD protection on parts

with increased sensitivity to ESD damage.

Working on your thin client 7

• Handle all static-sensitive components in a static-safe area. If possible, use anti-static oor pads and workbench pads.

• When unpacking a static-sensitive component from its shipping carton, do not remove the component from the anti-static packing

material until you are ready to install the component. Before unwrapping the anti-static packaging, ensure that you discharge static

electricity from your body.

• Before transporting a static-sensitive component, place it in an anti-static container or packaging.

ESD eld service kit

The unmonitored Field Service kit is the most commonly used service kit. Each Field Service kit includes three main components: anti-static

mat, anti-static wrist strap, and bonding wire.

Components of an ESD eld service kit

The components of an ESD eld service kit are:

•Anti-static mat—The anti-static mat is dissipative and parts can be placed on it during service procedures. When using an anti-static

mat, your anti-static wrist strap should be snug and the bonding wire should be connected to the mat and to any bare metal on the

system being worked on. Once deployed properly, service parts can be removed from the ESD bag and placed directly on the mat.

ESD-sensitive items are safe in your hand, on the ESD mat, in the system, or inside a bag.

•Anti-static wrist strap and bonding wire—The anti-static wrist strap and bonding wire can be either directly connected between your

wrist and bare metal on the hardware if the ESD mat is not required, or connected to the anti-static mat to protect hardware that is

temporarily placed on the mat. The physical connection of the anti-staticwrist strap and bonding wire between your skin, the ESD mat,

and the hardware is known as bonding. Use only Field Service kits with an anti-static wrist strap, mat, and bonding wire. Never use

wireless anti-static wrist straps. Always be aware that the internal wires of a anti-static wrist strap are prone to damage from normal

wear and tear, and must be checked regularly with a anti-static wrist strap tester in order to avoid accidental ESD hardware damage. It

is recommended to test the anti-static wrist strap and bonding wire at least once per week.

•ESD wrist strap tester—The wires inside of an ESD strap are prone to damage over time. When using an unmonitored kit, it is a best

practice to regularly test the strap prior to each service call, and at a minimum, test once per week. A wrist strap tester is the best

method for doing this test. If you do not have your own wrist strap tester, check with your regional oce to nd out if they have one.

To perform the test, plug the wrist-strap's bonding-wire into the tester while it is strapped to your wrist and push the button to test. A

green LED is lit if the test is successful; a red LED is lit and an alarm sounds if the test fails.

•Insulator Elements —It is critical to keep ESD sensitive devices, such as plastic heat sink casings, away from internal parts that are

insulators and often highly charged.

•Working Environment – Before deploying the ESD Field Service kit, assess the situation at the customer location. For example,

deploying the kit for a server environment is dierent than for a desktop or portable environment. Servers are typically installed in a rack

within a data center; desktops or portables are typically placed on oce desks or cubicles. Always look for a large open at work area

that is free of clutter and large enough to deploy the ESD kit with additional space to accommodate the type of system that is being

repaired. The workspace should also be free of insulators that can cause an ESD event. On the work area, insulators such as Styrofoam

and other plastics should always be moved at least 12 inches or 30 centimeters away from sensitive parts before physically handling any

hardware components

•ESD Packaging – All ESD-sensitive devices must be shipped and received in static-safe packaging. Metal, static-shielded bags are

preferred. However, you should always return the damaged part using the same ESD bag and packaging that the new part arrived in.

The ESD bag should be folded over and taped shut and all the same foam packing material should be used in the original box that the

new part arrived in. ESD-sensitive devices should be removed from packaging only at an ESD-protected work surface, and parts should

never be placed on top of the ESD bag because only the inside of the bag is shielded. Always place parts in your hand, on the ESD mat,

in the system, or inside an anti-static bag.

•Transporting Sensitive Components – When transporting ESD sensitive components such as replacement parts or parts to be

returned to Dell, it is critical to place these parts in anti-static bags for safe transport.

ESD protection summary

It is recommended that all eld service technicians use the traditional wired ESD grounding anti-static wrist strap and protective anti-static

mat at all times when servicing Dell products. In addition, it is critical that technicians keep sensitive parts separate from all insulator parts

while performing service and that they use anti-static bags for transporting sensitive components.

8Working on your thin client

Transporting sensitive components

When transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in

anti-static bags for safe transport.

Lifting equipment

Adhere to the following guidelines when lifting heavy weight equipment:

CAUTION: Do not lift greater than 50 pounds. Always obtain additional resources or use a mechanical lifting device.

1 Get a rm balanced footing. Keep your feet apart for a stable base, and point your toes out.

2 Tighten stomach muscles. Abdominal muscles support your spine when you lift, osetting the force of the load.

3 Lift with your legs, not your back.

4 Keep the load close. The closer it is to your spine, the less force it exerts on your back.

5 Keep your back upright, whether lifting or setting down the load. Do not add the weight of your body to the load. Avoid twisting your

body and back.

6 Follow the same techniques in reverse to set the load down.

After working on your thin client

About this task

Troubleshooting your system

You can troubleshoot the thin client by using indicators such as diagnostic lights and error messages during the operation of the device.

Additionally, you can use Enhanced Pre-Boot System Assessment (ePSA) diagnostics to carry out complete diagnosis and troubleshooting

of thin clients.

Topics:

• Enhanced Pre-Boot System Assessment diagnostics

• Running the ePSA diagnostics

• Battery status LED

• Diagnostic LED

• Power behavior

Enhanced Pre-Boot System Assessment diagnostics

The Enhanced Pre-Boot System Assessment (ePSA) diagnostics, also known as system diagnostics performs a complete check of your

hardware. The ePSA is embedded with the BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set

of options for particular devices or device groups, enabling you to:

• Run tests automatically or in an interactive mode

• Repeat tests

• Display or save test results

• Run thorough tests to introduce additional test options to provide extra information about the failed devices

• View status messages that inform you if tests are completed successfully

• View error messages that inform you of problems encountered during testing

CAUTION: Use the system diagnostics that comes with your software to test only your thin client. Using this program with other

thin clients may cause invalid results or error messages.

NOTE: Some tests for specic devices require user interaction. Always ensure that you are present at the thin client terminal

when the diagnostic tests are performed.

Running the ePSA diagnostics

1 Start up the thin client.

2 As the thin client boots, press the F12 key.

The boot menu screen is displayed.

76 Troubleshooting your system

3 On the boot menu screen, select the Diagnostics option.

The Enhanced Pre-boot System Assessment window is displayed.

4 Click the arrow key at the bottom-left corner.

The Diagnostics front page is displayed.

5 Press the arrow in the lower-right corner to go to the page listing.

The detected items are listed.

6 To run a diagnostic test on a specic device, press Esc and click Yes to stop the diagnostic test.

7 Select the device from the left pane, and click Run Tests.

If there are any issues, error codes are displayed. Note the error code and validation number, and contact Dell.

AC Adapter O S4/S5 Fully Charged

Battery Amber S0 < = 10%

Battery O S0 > 10%

Battery O S4/S5 0-100%

•S0 (ON)—System is turned on.

•S4—The system consumes the least power compared to all other sleep states. The system is almost at an OFF state, expect for a

trickle power. The context data is written to hard drive.

•S5 (OFF)—The system is in a shutdown state.

Diagnostic LED

This section details the diagnostic features of the battery LED.

Instead of beep codes, errors are indicated via the bicolor Battery Charge/Status LED. A specic blink pattern is followed by ashing a

pattern of ashes in amber, followed by white. The pattern then repeats.

NOTE: The diagnostic pattern consists of a two-digit number being represented by a rst group of LED blinks (1 through 9) in

amber, followed by a 1.5 second pause with the LED o, and then a second group of LED blinks (1 through 9) in white. This is

then followed by a three second pause, with the LED o, before repeating over again. Each LED blink takes 0.5 seconds.

The system will not shut down when displaying the Diagnostic Error Codes.

Diagnostic Error Codes always supersede any other use of the LED. For instance, on Laptops, battery codes for Low Battery or Battery

Failure situations will not be displayed when Diagnostic Error Codes are being displayed.
