Working on your computer

Safety instructions

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 you have read the safety information that shipped

with your computer.

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

computer. For more safety best practices, see the Regulatory Compliance home page at www.dell.com/

regulatory_compliance.

WARNING: Disconnect your computer from 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 your

computer to an electrical outlet.

CAUTION: To avoid damaging the computer, ensure that the work surface is flat, dry, and clean.

CAUTION: To avoid damaging the components and cards, handle them by their edges, and avoid touching the

pins and the contacts.

CAUTION: You should only perform troubleshooting and repairs as authorized or directed by the Dell technical

assistance team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. See the

safety instructions that is shipped with the product or at www.dell.com/regulatory_compliance.

CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal

surface, such as the metal at the back of the computer. While you work, periodically touch an unpainted metal

surface to dissipate static electricity which could harm internal components.

CAUTION: When you disconnect a cable, pull it by its connector or its pull tab, not the cable itself. Some cables

have connectors with locking tabs or thumbscrews that you must disengage before disconnecting the cable.

When disconnecting cables, keep them evenly aligned to avoid bending the connector pins. When connecting

cables, ensure that the ports and the connectors are correctly oriented and aligned.

CAUTION: Press and eject any installed card from the media-card reader.

CAUTION: Exercise caution when handling Lithium-ion batteries in laptops. Swollen batteries should not be used

and should be replaced and disposed properly.

NOTE: The color of your computer and certain components may appear differently than shown in this document.

Before working inside your computer

Steps

1. Save and close all open files and exit all open applications.

2. Shut down your computer. Click Start > Power > Shut down.

NOTE: If you are using a different operating system, see the documentation of your operating system for shut-down

instructions.

3. Disconnect your computer and all attached devices from their electrical outlets.

6 Working on your computer

4. Disconnect all attached network devices and peripherals, such as keyboard, mouse, and monitor from your computer.

5. Remove any media card and optical disc from your computer, if applicable.

6. After the computer is unplugged, press and hold the power button for 5 seconds to ground the system board.

CAUTION: Place the computer on a flat, soft, and clean surface to avoid scratches on the display.

7. Place the computer face down.

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 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 20 seconds should discharge residual power in the system board.

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:

Working on your computer 7

●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 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.

Technology and components

This chapter details the technology and components available in the system.

USB features

Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplified the connection between host computers and

peripheral devices like mouses, keyboards, external drivers, and printers.

Table 1. USB evolution

Type Data Transfer Rate Category Introduction Year

USB 2.0 480 Mbps High Speed 2000

USB 3.2 Gen 1 5 Gbps Super-Speed 2010

USB 3.2 Gen 2 10 Gbps Super-Speed 2013

USB 3.2 Gen 1 (Super-Speed 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 3.2 Gen 1 finally has the answer to the consumer's demands with a theoretically 10 times faster than its predecessor. In

a nutshell, USB 3.2 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 3.2 Gen 1.

Speed

Currently, there are 3 speed modes that are defined by the latest USB 3.2 Gen 1 specification. They are Super-Speed, Hi-Speed,

and Full-Speed. The new Super-Speed mode has a transfer rate of 4.8 Gbps. 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 480 Mbps and 12

Mbps respectively and are kept to maintain backward compatibility.

USB 3.2 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 (see the figure below).

●USB 2.0 previously had four wires (power, ground, and a pair for differential data); USB 3.2 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 3.2 Gen 1 utilizes the bi-directional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-fold

increase in theoretical bandwidth.

10 Technology and components

With today's ever increasing demands that are 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 320 Mbps (40 MB/s) —

the actual real-world maximum. Similarly, USB 3.2 Gen 1 connections will never achieve 4.8Gbps. We will likely see a real-world

maximum rate of 400 MB/s with overheads. At this speed, USB 3.2 Gen 1 is a 10x improvement over USB 2.0.

Applications

USB 3.2 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 2 Gbps throughput. Where 480 Mbps was limiting, 5 Gbps is more than promising. With its promised 4.8

Gbps 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 Super-Speed USB 3.2 Gen 1 products:

●External Desktop USB 3.2 Gen 1 Hard Drives

●Portable USB 3.2 Gen 1 Hard Drives

●USB 3.2 Gen 1 Drive Docks & Adapters

●USB 3.2 Gen 1 Flash Drives & Readers

●USB 3.2 Gen 1 Solid-state Drives

●USB 3.2 Gen 1 RAIDs

●Optical Media Drives

●Multimedia Devices

●Networking

●USB 3.2 Gen 1 Adapter Cards & Hubs

Compatibility

The good news is that USB 3.2 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all,

while USB 3.2 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 3.2 Gen 1

cables and only come into contact when connected to a proper Super-Speed USB connection.

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 primary advantage is cable reduction and content

Technology and components 11

protection provisions. HDMI supports standard, enhanced, or high-definition video, plus multichannel digital audio on a single

cable.

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.

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

Power button LED behavior

On certain Dell Latitude systems, the power button LED is used to provide an indication of the system status, and as a result the

power button illuminates when pressed. The systems with the optional power button/fingerprint reader will have no LED under

the power button and hence will apply the available LED's in the system to provide an indication of the system status.

Power button LED behavior without Fingerprint reader

●System is ON (S0) = LED illuminates solid white.

●System in Sleep/Standby (S3, SOix) = LED is off

●System is Off/Hibernating (S4/S5) = LED is off

Power On and LED behavior with Fingerprint reader

●Pressing the power button for a duration between 50 msec to 2 sec turns on the device.

●Power button does not register additional presses until the SOL (Sign-Of-Life) has been provided to the user.

●System LED's illuminates upon pressing the power button.

●All the available LED's (Keyboard backlit/ Keyboard caps lock LED/ Battery Charge LED) illuminates and displays specified

behavior.

●The auditory tone is Off by default. It can be enabled in the BIOS setup.

●Safeguards do not time out if the device gets hung during the logon process.

●Dell logo: Turns on within 2 secs after pressing the power button.

●Full boot: Within 22 secs after pressing the power button.

12 Technology and components

●Below is the example timelines:

Power button with fingerprint reader will have no LED and will leverage the available LED's in the system to provide indication of

the system status

●Power Adapter LED:

○The LED on Power adapter connector illuminates white when power is supplied from electrical outlet.

Troubleshooting

Handling swollen Lithium-ion batteries

Like most laptops, Dell laptops use lithium-ion batteries. One type of lithium-ion battery is the lithium-ion polymer battery.

Lithium-ion polymer batteries have increased in popularity in recent years and have become standard in the electronics industry

due to customer preferences for a slim form factor (especially with newer ultra-thin laptops) and long battery life. Inherent to

lithium-ion polymer battery technology is the potential for swelling of the battery cells.

Swollen battery may impact the performance of the laptop. To prevent possible further damage to the device enclosure or

internal components leading to malfunction, discontinue the use of the laptop and discharge it by disconnecting the AC adapter

and letting the battery drain.

Swollen batteries should not be used and should be replaced and disposed of properly. We recommend contacting Dell product

support for options to replace a swollen battery under the terms of the applicable warranty or service contract, including options

for replacement by a Dell authorized service technician.

The guidelines for handling and replacing Lithium-ion batteries are as follows:

●Exercise caution when handling Lithium-ion batteries.

●Discharge the battery before removing it from the system. To discharge the battery, unplug the AC adapter from the system

and operate the system only on battery power. When the system will no longer power on when the power button is pressed,

the battery is fully discharged.

●Do not crush, drop, mutilate, or penetrate the battery with foreign objects.

●Do not expose the battery to high temperatures, or disassemble battery packs and cells.

●Do not apply pressure to the surface of the battery.

●Do not bend the battery.

●Do not use tools of any type to pry on or against the battery.

●If a battery gets stuck in a device as a result of swelling, do not try to free it as puncturing, bending, or crushing a battery

can be dangerous.

●Do not attempt to reassemble a damaged or swollen battery into a laptop.

●Swollen batteries that are covered under warranty should be returned to Dell in an approved shipping container (provided

by Dell)—this is to comply with transportation regulations. Swollen batteries that are not covered under warranty should be

disposed of at an approved recycling center. Contact Dell product support at https://www.dell.com/support for assistance

and further instructions.

●Using a non-Dell or incompatible battery may increase the risk of fire or explosion. Replace the battery only with a

compatible battery purchased from Dell that is designed to work with your Dell computer. Do not use a battery from other

computers with your computer. Always purchase genuine batteries from https://www.dell.com or otherwise directly from

Dell.

Lithium-ion batteries can swell for various reasons such as age, number of charge cycles, or exposure to high heat. For more

information on how to improve the performance and lifespan of the laptop battery and to minimize the possibility of occurrence

of the issue, see Dell Laptop Battery - Frequently Asked Questions.
