Working on your computer

Safety instructions

Prerequisites

Use the following safety guidelines to protect your computer 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 computer.

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

About this task

NOTE: Disconnect all power sources before opening the computer cover or panels. After you finish working inside the

computer, replace all covers, panels, and screws before connecting to the power source.

WARNING: Before working inside your computer, read the safety information that shipped with your computer. For

additional safety best practices information, see the Regulatory Compliance Homepage

CAUTION: Many repairs may only be done by a certified 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 came 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 computer.

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 computer and certain components may appear differently than shown in this document.

6 Working on your computer

6. Press and hold the power button while the computer is unplugged to ground the system board.

NOTE: 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 computer.

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.

Working on your computer 7

•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 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.

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 firm 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, offsetting 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 inside your computer

About this task

After you complete any replacement procedure, ensure that you connect any external devices, cards, and cables before turning on your

computer.

Steps

1. Connect any telephone or network cables to your computer.

CAUTION: To connect a network cable, first plug the cable into the network device and then plug it into the

computer.

2. Connect your computer and all attached devices to their electrical outlets.

3. Turn on your computer.

4. If required, verify that the computer works correctly by running ePSA diagnostics.

8Working on your computer

Technology and components

NOTE: Instructions provided in this section are applicable on computers shipped with Windows 10 operating system.

Windows 10 is factory-installed with this computer.

Topics:

•DDR4

•HDMI 1.4

•USB features

•Intel Optane memory

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.

Figure 2. Thickness difference

Technology and components 9

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.

NOTE: The DDR4 memory is imbedded in board and not a replaceable DIMM as shown and referred.

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

•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

10 Technology and components

• 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.

Table 1. USB evolution

Type Data Transfer Rate Category Introduction Year

USB 2.0 480 Mbps High Speed 2000

USB 3.0/USB 3.1 Gen 1 5 Gbps Super Speed 2010

USB 3.1 Gen 2 10 Gbps Super Speed 2013

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.

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 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/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.

Technology and components 11

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

• USB 3.0/USB 3.1 Gen 1 Drive Docks & Adapters

• USB 3.0/USB 3.1 Gen 1 Flash Drives & Readers

• USB 3.0/USB 3.1 Gen 1 Solid-state Drives

• USB 3.0/USB 3.1 Gen 1 RAIDs

• Optical Media Drives

• Multimedia Devices

• Networking

• USB 3.0/USB 3.1 Gen 1 Adapter Cards & Hubs

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 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.
