Working on your computer

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/fix procedures involving disassembly or reassembly:

• Turn off the system and all attached peripherals

• Disconnect the system and all attached peripherals from AC power, and then remove the battery

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

• Use a wrist grounding strap and mat when working inside any computer system to avoid electrostatic discharge (ESD) damage.

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

• Wear shoes with nonconductive rubber soles to help reduce the chance of being shocked or seriously injured in an electrical accident

Standby power

Dell products with standby power must be completely unplugged before you open the case. Systems that incorporate standby power are
essentially powered while turned off. 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.

After unplugging the system and before removing components, wait approximately 30 to 45 seconds to allow the charge to drain from the
circuits. Remove the battery from portable computers.

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
Field Service Electrostatic discharge (ESD) kit. When connecting a bonding wire, always ensure that it is connected to bare metal and
never to a painted or non-metal surface. The wrist strap should be secure and in full contact with your skin, and be sure to always 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

4

Field Service Information 19

• 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 difficult type of damage to recognize and troubleshoot is the intermittent (also called latent or "walking wounded") failure. The
following image shows an example of intermittent damage to a memory DIMM trace. Although the damage is done, the symptoms may not
become an issue or cause permanent failure symptoms for some time after the damage occurs.

Perform the following steps to prevent ESD damage:

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

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

• Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor 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, be sure to discharge static
electricity from your body.

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

ESD field service kit

The unmonitored Field Service kit is the most commonly used. Each Field Service kit includes three main components: anti-static mat,
wrist strap, and bonding wire.

Components of an ESD field service kit

The components of ESD field service kit are:

• Anti-Static Mat – The anti-static mat is dissipative and should be used to safely place parts on during service procedures. When using
an anti-static mat, your wrist strap should be snug and the bonding wire should be connected to the mat and to 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.
Remember, the only safe place for ESD-sensitive items are in your hand, on the ESD mat, in the system, or inside a bag.

• Wrist Strap and Bonding Wire – The 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 wrist strap and bonding wire between your skin, the ESD mat, and the hardware is
known as bonding. Use only Field Service kits with a wrist strap, mat, and bonding wire. Never use wireless wrist straps. Always be
aware that the internal wires of a wrist strap are prone to damage from normal wear and tear, and must be checked regularly with a
wrist strap tester in order to avoid accidental ESD hardware damage. It is recommended to test the wrist strap and bonding wire a
minimum of 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 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 office to find 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 different 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 office desks or cubicles. lways look for a large open flat 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.

20

Field Service Information

• 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 strongly suggested that all field service technicians use the traditional wired ESD grounding 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.

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 equipment:

CAUTION: :

Do not lift greater than 50 pounds. Always obtain assistance from another person or persons, or use a mechanical lifting device.

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

b Bend your knees. Do not bend at the waist.
c Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting the force of the load.
d Lift with your legs, not your back.
e Keep the load close. The closer it is to your spine, the less force it exerts on your back.
f 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.

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

Before working inside your computer

USB features

The Universal Serial Bus, or well known as USB was introduced to the PC world in 1996 which dramatically simplified the connection
between host computer and peripheral devices such as mice and keyboards, external hard drive or optical devices, Bluetooth and many
more peripheral devices in the market.

Let's take a quick look on the USB evolution referencing to the table below.

Table 6. USB evolution

Type Data Transfer Rate Category Introduction Year

USB 3.0 4.8 Gbps Super Speed 2010

USB 2.0 480 Mbps High Speed 2000

USB 1.1 12 Mbps Full Speed 1998

USB 1.0 1.5 Mbps Low Speed 1996

46 Technology and components

USB 3.0 (SuperSpeed USB)

For years, the USB 2.0 has been firmly entrenched as the de facto interface standard in the PC world with about 6 billion devices sold, and
yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands. The USB 3.0 finally has the
answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.0 features are as follows:

• Higher transfer rates (up to 4.8 Gbps)

• Increased maximum bus power and increased device current draw to better accommodate power-hungry devices

• New power management features

• Full-duplex data transfers and support for new transfer types

• Backward USB 2.0 compatibility

• New connectors and cable

The topics below cover some of the most commonly asked questions regarding USB 3.0.

Speed

Currently, there are 3 speed modes defined by the latest USB 3.0 specification. They are Super-Speed, Hi-Speed and Full-Speed. The new
SuperSpeed mode has a transfer rate of 4.8Gbps. While the specification retains Hi-Speed, and Full-Speed USB mode, commonly known
as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to maintain backward
compatibility.

USB 3.0 achieves the much higher performance by the technical changes below:

• An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below).

• USB 2.0 previously had four wires (power, ground, and a pair for differential data); USB 3.0 adds four more for two pairs of differential
signals (receive and transmit) for a combined total of eight connections in the connectors and cabling.

• USB 3.0 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-fold increase in
theoretical bandwidth.

With today's ever increasing demands placed on data transfers with high-definition video content, terabyte storage devices, high
megapixel count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the

Technology and components

47

480Mbps theoretical maximum throughput, making data transfer at around 320Mbps (40MB/s) — the actual real-world maximum.
Similarly, USB 3.0 connections will never achieve 4.8Gbps. We will likely see a real-world maximum rate of 400MB/s with overheads. At
this speed, USB 3.0 is a 10x improvement over USB 2.0.

Applications

USB 3.0 opens up the laneways and provides more headroom for devices to deliver a better overall experience. Where USB video was
barely tolerable previously (both from a maximum resolution, latency, and video compression perspective), it's easy to imagine that with
5-10 times the bandwidth available, USB video solutions should work that much better. Single-link DVI requires almost 2Gbps throughput.
Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will find its way into some
products that previously weren't USB territory, like external RAID storage systems.

Listed below are some of the available SuperSpeed USB 3.0 products:

• External Desktop USB 3.0 Hard Drives

• Portable USB 3.0 Hard Drives

• USB 3.0 Drive Docks & Adapters

• USB 3.0 Flash Drives & Readers

• USB 3.0 Solid-state Drives

• USB 3.0 RAIDs

• Optical Media Drives

• Multimedia Devices

• Networking

• USB 3.0 Adapter Cards & Hubs

Compatibility

The good news is that USB 3.0 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all, while USB 3.0
specifies new physical connections and thus new cables to take advantage of the higher speed capability of the new protocol, the
connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as before. Five new
connections to carry receive and transmitted data independently are present on USB 3.0 cables and only come into contact when
connected to a proper SuperSpeed USB connection.

Windows 8 will be bringing native support for USB 3.0 controllers. This is in contrast to previous versions of Windows, which continue to
require separate drivers for USB 3.0 controllers.

Microsoft announced that Windows 7 would have USB 3.0 support, perhaps not on its immediate release, but in a subsequent Service
Pack or update. It is not out of the question to think that following a successful release of USB 3.0 support in Windows 7, SuperSpeed
support would trickle down to Vista. Microsoft has confirmed this by stating that most of their partners share the opinion that Vista should
also support USB 3.0.

Super-Speed support for Windows XP is unknown at this point. Given that XP is a seven-year-old operating system, the likelihood of this
happening is remote.

HDMI 1.4

This topic explains the HDMI 1.4 and its features along with the advantages.

HDMI (High-Definition Multimedia Interface) is an industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an
interface between any compatible digital audio/video source, such as a set-top box, DVD player, or A/V receiver and a compatible digital
audio and/or video monitor, such as a digital TV (DTV). The intended applications for HDMI are set-top boxes, TVs, and DVD players. The
primary advantage is cable reduction and content protection provisions. HDMI supports standard, enhanced, or high-definition video, plus
multichannel digital audio on a single cable.

48

Technology and components

NOTE: The HDMI 1.4 will provide 5.1 channel audio support.

HDMI 1.4 Features

• HDMI Ethernet Channel - Adds high-speed networking to an HDMI link, allowing users to take full advantage of their IP-enabled
devices without a separate Ethernet cable

• Audio Return Channel - Allows an HDMI-connected TV with a built-in tuner to send audio data "upstream" to a surround audio
system, eliminating the need for a separate audio cable

• 3D - Defines input/output protocols for major 3D video formats, paving the way for true 3D gaming and 3D home theater applications

• Content Type - Real-time signaling of content types between display and source devices, enabling a TV to optimize picture settings
based on content type

• Additional Color Spaces - Adds support for additional color models used in digital photography and computer graphics.

• 4 K Support - Enables video resolutions far beyond 1080p, supporting next-generation displays that will rival the Digital Cinema
systems used in many commercial movie theaters

• HDMI Micro Connector - A new, smaller connector for phones and other portable devices, supporting video resolutions up to 1080p

• Automotive Connection System - New cables and connectors for automotive video systems, designed to meet the unique demands
of the motoring environment while delivering true HD quality

Advantages of HDMI

• Quality HDMI transfers uncompressed digital audio and video for the highest, crispest image quality.

• Low -cost HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner

• Audio HDMI supports multiple audio formats, from standard stereo to multichannel surround sound

• HDMI combines video and multichannel audio into a single cable, eliminating the cost, complexity, and confusion of multiple cables
currently used in A/V systems

• HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality

The memory information is displayed on the right pane.

DDR4

DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows up to 512
GB in capacity, compared to the DDR3's maximum of 128 GB per DIMM. DDR4 synchronous dynamic random-access memory is keyed
differently from both SDRAM and DDR to prevent the user from installing the wrong type of memory into the system.

DDR4 needs 20 percent less or just 1.2 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate. DDR4 also
supports a new, deep power-down mode that allows the host device to go into standby without needing to refresh its memory. Deep
power-down mode is expected to reduce standby power consumption by 40 to 50 percent.

DDR4 Details

There are subtle differences between DDR3 and DDR4 memory modules, as listed below.

Key notch difference
The key notch on a DDR4 module is in a different location from the key notch on a DDR3 module. Both notches are on the insertion edge

but the notch location on the DDR4 is slightly different, to prevent the module from being installed into an incompatible board or platform.

Figure 4. Notch difference

Increased thickness
DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.

Figure 5. Thickness difference

Curved edge
DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation.

Enhanced Pre-Boot System Assessment (ePSA)
diagnostics

The 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 allowing 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 device(s)

• 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 to test only your computer. Using this program with other computers may cause invalid

results or error messages.

NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer terminal

when the diagnostic tests are performed.
