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.
•
Disconnect all network cables, telephone, and telecommunications lines from the system.
•
Use an ESD field service kit when working inside any notebook 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 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.
Unplugging, pressing and holding the power button for 15 seconds should discharge residual power in the system board, notebooks
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, 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 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 For this reason, some previously approved methods of handling parts are no longer applicable.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 difficult 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 ESD wrist strap that is properly grounded. The use of wireless anti-static straps is 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.
•
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 field 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, wrist strap, and bonding wire.
Components of an ESD field service kit
The components of an ESD field 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 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.
•
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 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 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. Always 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
4
Working on your computer
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 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.

Thunderbolt over USB Type-C
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 1. Notch difference
Increased thickness
DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.
Technology and components

Figure 2. Thickness difference
Curved edge
DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation.
Figure 3. Curved edge
Memory Errors
Memory errors on the system display the new ON-FLASH-FLASH or ON-FLASH-ON failure code. If all memory fails, the LCD does not
turn on. Troubleshoot for possible memory failure by trying known good memory modules in the memory connectors on the bottom of the
system or under the keyboard, as in some portable systems.
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 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 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.
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
44
Technology and components
•
4K 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
USB features
Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplified the connection between host computers and peripheral
devices like mice, keyboards, external drivers, and printers.
Let's take a quick look on the USB evolution referencing to the table below.

USB 3.0/USB 3.1 Gen 1 (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/USB 3.1 Gen 1
finally has the answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.1 Gen 1
features are as follows:
•
Higher transfer rates (up to 5 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/USB 3.1 Gen 1.
Technology and components
45
Speed
Currently, there are 3 speed modes defined by the latest USB 3.0/USB 3.1 Gen 1 specification. They are Super-Speed, Hi-Speed and FullSpeed. 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/USB 3.1 Gen 1 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/USB 3.1 Gen 1 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/USB 3.1 Gen 1 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 480Mbps
theoretical maximum throughput, making data transfer at around 320Mbps (40MB/s) — the actual real-world maximum. Similarly, USB
3.0/USB 3.1 Gen 1 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/USB 3.1 Gen 1 is a 10x improvement over USB 2.0.
Applications
USB 3.0/USB 3.1 Gen 1 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/USB 3.1 Gen 1 products:
•
External Desktop USB 3.0/USB 3.1 Gen 1 Hard Drives
•
Portable USB 3.0/USB 3.1 Gen 1 Hard Drives

Compatibility
The good news is that USB 3.0/USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all,
while USB 3.0/USB 3.1 Gen 1 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/USB 3.1 Gen 1 cables and only
come into contact when connected to a proper SuperSpeed USB connection.
Windows 8/10 will be bringing native support for USB 3.1 Gen 1 controllers. This is in contrast to previous versions of Windows, which
continue to require separate drivers for USB 3.0/USB 3.1 Gen 1 controllers.
Microsoft announced that Windows 7 would have USB 3.1 Gen 1 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/USB 3.1 Gen 1 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/USB 3.1 Gen 1.
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.
USB Type-C
USB Type-C is a new, tiny physical connector. The connector itself can support various exciting new USB standard like USB 3.1 and USB
power delivery (USB PD).
Alternate Mode
USB Type-C is a new connector standard that's very small. It's about a third the size of an old USB Type-A plug. This is a single connector
standard that every device should be able to use. USB Type-C ports can support a variety of different protocols using “alternate modes,”
which allows you to have adapters that can output HDMI, VGA, DisplayPort, or other types of connections from that single USB port
USB Power Delivery
The USB PD specification is also closely intertwined with USB Type-C. Currently, smartphones, tablets, and other mobile devices often use
a USB connection to charge. A USB 2.0 connection provides up to 2.5 watts of power — that'll charge your phone, but that's about it. A
laptop might require up to 60 watts, for example. The USB Power Delivery specification ups this power delivery to 100 watts. It's bidirectional, so a device can either send or receive power. And this power can be transferred at the same time the device is transmitting
data across the connection.
This could spell the end of all those proprietary laptop charging cables, with everything charging via a standard USB connection. You could
charge your laptop from one of those portable battery packs you charge your smartphones and other portable devices from today. You
could plug your laptop into an external display connected to a power cable, and that external display would charge your laptop as you used
it as an external display — all via the one little USB Type-C connection. To use this, the device and the cable have to support USB Power
Delivery. Just having a USB Type-C connection doesn't necessarily mean they do.
Technology and components
47
USB Type-C and USB 3.1
USB 3.1 is a new USB standard. USB 3's theoretical bandwidth is 5 Gbps, while USB 3.1 Gen2 is10Gbps . That's double the bandwidth, as
fast as a first-generation Thunderbolt connector. USB Type-C isn't the same thing as USB 3.1. USB Type-C is just a connector shape, and
the underlying technology could just be USB 2 or USB 3.0. In fact, Nokia's N1 Android tablet uses a USB Type-C connector, but underneath
it's all USB 2.0 — not even USB 3.0. However, these technologies are closely related.
Thunderbolt over USB Type-C
Thunderbolt is a hardware interface that combines data, video, audio, and power in a single connection. Thunderbolt combines PCI Express
(PCIe) and DisplayPort (DP) into one serial signal, and additionally provides DC power, all in one cable. Thunderbolt 1 and Thunderbolt 2 use
the same connector [1] as miniDP (DisplayPort) to connect to peripherals, while Thunderbolt 3 uses a USB Type-C connector [2].
Figure 4. Thunderbolt 1 and Thunderbolt 3
