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.

Working inside your computer

Before working inside your computer

About this task

NOTE: The images in this document may differ from your computer depending on the configuration you ordered.

Working on your computer 7

Steps

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

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

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

instructions.

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

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

CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the

cable from the network device.

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

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.

8Working on your computer

●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.

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.

Dell SupportAssist Pre-boot System Performance

Check diagnostics

About this task

SupportAssist diagnostics (also known as system diagnostics) performs a complete check of your hardware. The Dell

SupportAssist Pre-boot System Performance Check diagnostics 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:

●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.

For more information, see Resolve Hardware Issues With Built-in and Online Diagnostics (SupportAssist ePSA, ePSA or PSA

Error Codes) .

Running the SupportAssist Pre-Boot System Performance Check

Steps

1. Turn on your computer.

2. As the computer boots, press the F12 key as the Dell logo appears.

3. On the boot menu screen, select the Diagnostics option.

4. Click the arrow at the bottom left corner.

Diagnostics front page is displayed.

5. Click the arrow in the lower-right corner to go to the page listing.

The items detected are listed.

6. To run a diagnostic test on a specific device, press Esc and click Yes to stop the diagnostic test.

7. Select the device from the left pane and click Run Tests.

8. If there are any issues, error codes are displayed.

Note the error code and validation number and contact Dell.

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

112 Troubleshooting

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 20. 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.

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.
