•Safety instructions
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.

of the computer.
8. Remove any installed ExpressCards or Smart Cards from their slots.
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.
Safety Precautions
Follow the safety precautions described in the following sections when you perform an installation or a disassembly/reassembly
procedure:
●Turn off the system and all attached peripherals.
●Disconnect the system and all attached peripherals from AC power, and then remove the battery.
●Disconnect all network cables, telephone or telecommunications lines from the system.
●Use a wrist grounding strap and mat when working inside any computer system to avoid electrostatic discharge (ESD)
damage.
●After removing a system component, carefully place the removed component on an anti-static mat.
●Wear shoes with non-conductive rubber soles to help reduce the risk of being shocked or seriously injured in an electrical
accident.
Working on your computer 7
Standby Power
Dell products with standby power must be completely unplugged before the case is opened. 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),
suspended into a sleep mode, and have other advanced power management features.
After you unplug a system and before you remove components, wait approximately 30 to 45 seconds to allow the charge to
drain from the circuits.
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 ESD kit. When connecting a bonding wire, always 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 be sure to always remove
all jewelry such as watches, bracelets, or rings prior to bonding yourself and the equipment.
Figure 1. Bonding Properly
Electrostatic Discharge 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 earlier Dell products. For this reason some previously approved methods of handling parts are no longer applicable.
There are two recognized types of ESD damage: catastrophic and intermittent failures.
●Catastrophic —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.
NOTE: Catastrophic failures represent approximately 20 percent of ESD-related failures.
●Intermittent —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.
NOTE: 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 more difficult type of damage to recognize and troubleshoot is the intermittent (also called latent or “walking wounded”)
failure. The following image shows an example of intermittent damage to a memory DIMM trace. Although the damage is done,
the symptoms may not become an issue or cause permanent failure symptoms for some time after the damage occurs.
8Working on your computer
Figure 2. Intermittent (Latent) Damage to a Wiring Trace
Do the following 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.
Figure 3. Chassis "Bare Metal" Grounding (Unacceptable)
●Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads.
●When handling static-sensitive components, grasp them by the sides, not the top. Avoid touching pins and circuit boards.
●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, be sure to
discharge static electricity from your body.
●Before transporting a static-sensitive component, place it in an anti-static container or packaging.
The ESD Field Service Kit
The unmonitored Field Service kit is the most commonly used. Each Field Service kit includes three main components: anti-static
mat, wrist strap, and bonding wire.
Working on your computer 9
Figure 4. ESD Field Service Kit
The anti-static mat is dissipative and should be used to safely place parts on 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 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. Remember, the only safe place for ESD-sensitive items are in your hand, on the ESD mat, in the system, or inside a bag.
Figure 5. Anti-Static Mat
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 a minimum of once per week.
10 Working on your computer
Table 1. Wrist Straps
Wrist Strap and Bonding Wire Wireless ESD Strap (Unacceptable)
ESD Wrist Strap Tester
The wires inside of an ESD strap are prone to damage over time. When using an unmonitored kit, it is 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.
Figure 6. Wrist Strap Tester
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 on your computer 11
Table 2. Placement of Insulator Elements
Unacceptable — DIMM lying on an insulator part (plastic
heat sink shroud)
Acceptable — DIMM separated from the insulator part
Consider the 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.
12 Working on your computer
Figure 7. ESD Packaging
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 strongly suggested that all field service engineers 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 engineers keep sensitive parts separate
from all insulator parts while performing service and that they use anti-static bags for transporting sensitive components.
Lifting Equipment
NOTE: Do not lift greater than 50 pounds. Always obtain assistance from another person or persons, or use a mechanical
lifting device.
Adhere to the following guidelines when lifting equipment:
1. Get a firm balanced footing. Keep your feet apart for a stable base, and point your toes out.
2. Bend your knees. Do not bend at the waist.
3. Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting the force of the load.
4. Lift with your legs, not your back.
5. Keep the load close. The closer it is to your spine, the less force it exerts on your back.
6. 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.
7. Follow the same techniques in reverse to set the load down.

UEFI BIOS
UEFI is an acronym for Unified Extensible Firmware Interface. The UEFI specification defines a new model for the interface
between personal computer operating systems and platform firmware. The interface consists of data tables that contain
platform related information, plus boot and runtime service calls that are available to the operating system and its loader.
Together, these provide a standard environment for booting an operating system and running pre-boot applications. One of the
main differences between BIOS and UEFI is the way applications are coded. Assembler was used if functions or applications had
to be coded for the BIOS while a higher level language code will be used to program the UEFI.
Dell UEFI BIOS implementation will supersede the existing two different sets of BIOS in the portables and desktop products into
one single UEFI BIOS moving forward.
Important Information
There is no difference in between the conventional BIOS and the UEFI BIOS unless the UEFI option is checked in the 'Boot
List Option' setting in the BIOS page. This will allow the user to create a UEFI boot option list manually without affecting the
existing boot priority list. With the implementation of UEFI BIOS, the changes are more related to the manufacturing tools and
functionalities with very minimal impact to the customer's usages.
A few things to remember are:
●If customers have a UEFI boot media, and ONLY if they have UEFI boot media (either in the optical media or via USB
storage), the one-time boot menu will show an additional section listing the UEFI boot options. Customers can view this
option If they have UEFI boot media attached, and the UEFI boot option is specified manually through the 'Boot Sequence'
settings.
How to change Service Tag/Owner Tag?
When the service technician replaces a system board, it's required to set the service tag when the system restarts. Failure
to set a service tag may result in system battery not being able to charge. Therefore, it is very important that the service
technician set the correct system service tag. If a wrong service tag is set, then the technician will have to place the order for
another system board replacement.
How to change Asset tag information?
To change the Asset tag information, we can use one of the following software utilities:
●Portables Technology Dell Command Configure toolkit-
2
Technology and components 15
Customers may also report that after a motherboard replacement, the asset field is already populated in the system BIOS,
and needs to be cleared or set. For older systems and all newer systems with the UEFI BIOS platform, customers can
download the Dell Command Configure Toolkit (DCC) to customize the BIOS options or even change the ownership or asset
tag from within Windows.
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 8. Notch difference
Increased thickness
DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.
Figure 9. Thickness difference
Curved edge
DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation.
16 Technology and components
Figure 10. Curved edge
Memory Errors
Memory errors on the system display the new 2 - Amber, 3 - White 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.

HDMI 1.4a
This topic explains the HDMI 1.4a 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 1.4a 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.
18 Technology and components
●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.

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 4.8 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 3.0/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.
20 Technology and components
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 320 Mbps (40 MB/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 21
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.
Media Card Readers
NOTE: The media card reader is integrated into the system board on portable systems. If there is a hardware failure or the
reader malfunctions, replace the system board.
The media card reader expands the usefulness and functionality of portable systems, especially when used with other devices
such as digital cameras, portable MP3 players, and handheld devices. All these devices use a form of media card to store
information. Media card readers allows for easy transfer of data between these devices.
Several different types of media or memory cards are available today. Below is a list of the different types of cards that work in
the media card reader.

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.

Built-in self-test (BIST)
M-BIST
M-BIST (Built In Self-Test) is the system board's built-in self-test diagnostics tool that improves the diagnostics accuracy of
system board embedded controller (EC) failures.
NOTE: M-BIST can be manually initiated before POST (Power On Self Test).
How to run M-BIST
NOTE: M-BIST must be initiated on the system from a power-off state either connected to AC power or with battery only.
1. Press and hold both the M key on the keyboard and the power button to initiate M-BIST.
2. With both the M key and the power button held down, the battery indicator LED may exhibit two states:
a. OFF: No fault detected with the system board
b. AMBER: Indicates a problem with the system board
3. If there is a failure with the system board, the battery status LED will flash one of the following error codes for 30 seconds:
Table 9. LED error codes
Blinking Pattern Possible Problem
Amber White
2 1 CPU Failure
2 8 LCD Power Rail Failure
1 1 TPM Detection Failure
2 4 Unrecoverable SPI Failure
4. If there is no failure with the system board, the LCD will cycle through the solid color screens described in the LCD-BIST
section for 30 seconds and then power off.
LCD Power rail test (L-BIST)
L-BIST is an enhancement to the single LED error code diagnostics and is automatically initiated during POST. L-BIST will check
the LCD power rail. If there is no power being supplied to the LCD (i.e., the L-BIST circuit fails), the battery status LED will flash
either an error code [2,8] or an error code [2,7].
NOTE: If L-BIST fails, LCD-BIST cannot function as no power will be supplied to the LCD.
How to invoke L-BIST Test:
1. Press the power button to start the system.
2. If the system does not start up normally, look at the battery status LED:
●If the battery status LED flashes an error code [2,7], the display cable may not be connected properly.
●If the battery status LED flashes an error code [2,8], there is a failure on the LCD power rail of the system board, hence
there is no power supplied to the LCD.
3. For cases, when a [2,7] error code is shown, check to see if the display cable is properly connected.
4. For cases when a [2,8] error code is shown, replace the system board.
LCD Built-in Self Test (BIST)
Dell laptops have a built-in diagnostic tool that helps you determine if the screen abnormality you are experiencing is an inherent
problem with the LCD (screen) of the Dell laptop or with the video card (GPU) and PC settings.
74 Troubleshooting
When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines,
color fade etc., it is always a good practice to isolate the LCD (screen) by running the Built-In Self Test (BIST).
How to invoke LCD BIST Test
1. Power off the Dell laptop.
2. Disconnect any peripherals that are connected to the laptop. Connect only the AC adapter (charger) to the laptop.
3. Ensure that the LCD (screen) is clean (no dust particles on the surface of the screen).
4. Press and hold D key and Power on the laptop to enter LCD built-in self test (BIST) mode. Continue to hold the D key, until
the system boots up.
5. The screen will display solid colors and change colors on the entire screen to white, black, red, green, and blue twice.
6. Then it will display the colors white, black and red.
7. Carefully inspect the screen for abnormalities (any lines, fuzzy color or distortion on the screen).
8. At the end of the last solid color (red), the system will shut down.
NOTE: Dell SupportAssist Pre-boot diagnostics upon launch, initiates an LCD BIST first, expecting a user intervention
confirm functionality of the LCD.
Diagnostic LEDs
Instead of beep codes, errors are indicated via the bicolor Battery Charge/Status LED. A specific blink pattern is followed by
flashing a pattern of flashes in amber, followed by white. The pattern then repeats.
The diagnostic pattern will consist of a two-digit number being represented by a first group of LED blinks (1 through 9) in
amber, followed by a 1.5 second pause with the LED off, and then a second group of LED blinks (1 through 9) in white. This is
then followed by a three second pause, with the LED off, before repeating over again. Each LED blink takes 1.5 seconds.
The system will not shutdown when displaying the Diagnostic Error Codes.
Diagnostic Error Codes will always supersede any other use of the LED. For instance, on laptops, battery codes for Low Battery
or Battery Failure situations will not be displayed when Diagnostic Error Codes are being displayed.
Table 10. Diagnostic LEDs
