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.
1
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.

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 15 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.
Working on your computer
7
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 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.

Working on your computer
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.
Topics:
• USB features
• HDMI 1.4
• Power button LED behavior
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
2
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 FullSpeed 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).
10 Technology and components
● 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.
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 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 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
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.
12
Technology and components
● 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.
● 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.
● Battery Indicator LED:
○ If the computer is connected to an electrical outlet, the battery light operates as follows:
1. Solid white -the battery is charging. When the charge is complete the LED turns off.
○ If the computer is running on a battery, the battery light operates as follows:
1. Off -the battery is adequately charged (or the computer is turned off).
2. Solid amber -the battery charge is critically low. A low battery state is approximately 30 minutes or less of battery life
remaining.
● Camera LED
○ White LED activates when camera is on.
● Mic Mute LED:
○ When activated (muted), the mic mute LED on the F4 Key should illuminate WHITE.
