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 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.
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.
Before working inside your computer
To avoid damaging your computer, perform the following steps before you begin working inside the computer.
1. Ensure that you follow the Safety Instruction.
2. Ensure that your work surface is flat and clean to prevent the computer cover from being scratched.
3. Turn off your computer.
4. Disconnect all network cables from the computer.
CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from
the network device.
5. Disconnect your computer and all attached devices from their electrical outlets.
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.

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 desktop 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.
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.
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.
Working on your computer 7
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
After you complete any replacement procedure, ensure that you connect any external devices, cards, and cables before turning on your
computer.
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.

Technology and components
This chapter details the technology and components available in the system.
Topics:
•DDR4
•USB features
•USB Type-C
•Advantages of DisplayPort over USB Type-C
•HDMI 2.0
•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
Curved edge

Technology and components 9
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.
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:
10 Technology and components
• 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
• 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.
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).
Technology and components 11
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 same as of USB 3.1 Gen 1, while USB 3.1 Gen 2's bandwidth 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.
Advantages of DisplayPort over USB Type-C
• Full DisplayPort audio/video (A/V) performance (up to 4K at 60Hz)
• Reversible plug orientation and cable direction
• Backwards compatibility to VGA, DVI with adaptors
• SuperSpeed USB (USB 3.1) data
• Supports HDMI 2.0a and is backwards compatible with previous versions
HDMI 2.0
This topic explains the HDMI 2.0 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.
HDMI 2.0 Features
•HDMI Ethernet Channel - Adds high-speed networking to an HDMI link, allowing users to take full advantage of their IP-enabled

Enhanced Pre-Boot System Assessment — ePSA
diagnostics
The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the
BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or device
groups allowing you to:
The ePSA diagnostics can be initiated by the FN+PWR buttons while powering on the computer.
• Run tests automatically or in an interactive mode
• Repeat tests
• Display or save test results
• Run thorough tests to introduce additional test options to provide extra information about the failed device(s)
• View status messages that inform you if tests are completed successfully
• View error messages that inform you of problems encountered during testing
NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer
terminal when the diagnostic tests are performed.
Running the ePSA Diagnostics
Invoke diagnostics boot by either of the methods that are suggested below:
1. Power on the computer.
2. As the computer boots, press the F12 key when the Dell logo is displayed.
3. In the boot menu screen, use Up/Down arrow key to select the Diagnostics option and then press Enter.
NOTE: The Enhanced Pre-boot System Assessment window displays, listing all devices detected in the computer.
The diagnostics starts running the tests on all the detected devices.
4. Press the arrow in the lower-right corner to go to the page listing.
The detected items are listed and tested.
5. To run a diagnostic test on a specific device, press Esc and click Yes to stop the diagnostic test.
6. Select the device from the left pane and click Run Tests.
7. If there are any issues, error codes are displayed.
Note the error code and contact Dell.
Diagnostics
The computer POST (Power On Self Test) ensures that it meets the basic computer requirements and the hardware is working
appropriately before the boot process begins. If the computer passes the POST, the computer continues to start in a normal mode.
However, if the computer fails the POST, the computer emits a series of LED codes during the start-up. The system LED is integrated on
the Power button.
The following table shows different light patterns and what they indicate.
