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

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.
Working on your computer 7
●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.

USB Type-C
USB Type-C is a new, tiny physical connector. The connector itself can support various exciting new USB standards like USB 3.1
and USB power delivery (USB PD).
Alternate Mode
USB Type-C is a new connector standard that is very small. It is 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 bi-directional, 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.
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's is 10 Gbps. 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.
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 6. 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
Technology and components 15
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.
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.
16 Technology and components
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.

CROSH
This topic covers the information that you need to know for the Chrome Shell (CROSH). CROSH and the Google Chrome URL
commands provide some troubleshooting tools, information, and advanced settings.
The Chrome OS does not support ePSA, Dell BIOS, the F12 boot menu, or DellConnect. There are no preboot diagnostics.
All troubleshootings must be done inside the OS. Chrome Shell (CROSH) and the Chrome URL commands provide some
troubleshooting tools, information, and advanced settings. CROSH is a command line interface similar to the Linux BASH or
Windows command (cmd.exe) terminals. Chrome OS is based on Linux, but CROSH does not recognize most Linux commands.
The most useful commands for troubleshooting are memory test, storage_test_1, storage_test_2, ping, and tracepath. Ping
works differently than it does in Windows. By default, it repeats until you press <Ctrl> + <C>, and it does not show any
statistics. The tracepath command is similar to the Windows traceroute command. A detailed explanation of the commands can
be viewed below, by typing help, or help_advanced in CROSH.
1. Open the Chrome browser.
62 Troubleshooting
2. Press <Clrl> + <Alt> + <T> The interface appears as shown in the screenshot
below:
3. Type in the CROSH command for diagnostics. Type 'help' for a list of available commands. Type help_advanced to display
a complete list of commands for debugging purposes
Alternately, refer to CROSH Commands for the list of the CROSH commands available for diagnostics.

ping [-c count] [-i interval] [-n] [-s packetsize] [-W waittime] —
Sends ICMP ECHO_REQUEST packets to a network host. If
it is "gw", then the next hop gateway for the default route
is used. It works like the ping command on other operating
systems. Press <Clrt> + <C> to stop the ping process or halt
any other command in CROSH.
ssh [optional args...] — Starts the ssh subsystem if invoked
without any arguments. "ssh <user> <host>", "ssh
<user> <host> <port>", "ssh< user>@<host>". or "ssh
