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.

CAUTION: Unless you are an expert computer user, do not change the settings in the BIOS Setup program. Certain
changes can make your computer work incorrectly.
NOTE: Before you change BIOS Setup program, it is recommended that you write down the BIOS Setup program screen
information for future reference.
Use the BIOS Setup program for the following purposes:
• Get information about the hardware installed in your computer, such as the amount of RAM and the size of the hard drive.
• Change the system configuration information.
• Set or change a user-selectable option, such as the user password, type of hard drive installed, and enabling or disabling base devices.
Topics:
• Boot menu
• Navigation keys
• Boot Sequence
• System setup options
• Updating the BIOS in Windows
• System and setup password
Boot menu
Press <F12> when the Dell logo appears to initiate a one-time boot menu with a list of the valid boot devices for the system. Diagnostics
and BIOS Setup options are also included in this menu. The devices listed on the boot menu depend on the bootable devices in the system.
This menu is useful when you are attempting to boot to a particular device or to bring up the diagnostics for the system. Using the boot
menu does not make any changes to the boot order stored in the BIOS.
The options are:
• UEFI Boot:
• Windows Boot Manager

Enhanced Pre-Boot System Assessment (ePSA) diagnostics
About this task
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:
• 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:
terminal when the diagnostic tests are performed.
Some tests for specific devices require user interaction. Always ensure that you are present at the computer
Running the ePSA diagnostics
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.

M-BIST L-BIST
Purpose of diagnostic tool Evaluates the health condition of the
system board to have further
resolution on "No Power", "No Post",
and "No Video" symptom and reduce
repeated dispatches.
Trigger Pressing M key and Power button Integrated into the single LED error code diagnostic.
Checks if the system board is supplying power to the
LCD display by performing an LCD Power Rail test, which
allows for isolation of "No Video" symptom to Mainboard,
LCD or Cable.
Automatically initiated during POST.

M-BIST L-BIST
Indicator of fault Battery LED light with "Solid Amber" Battery indicator LED blink error code [Amber, White] =

Repair instruction Indicates a problem with the system
board.
Indicates a problem with the system board.
M-BIST
M-BIST is the system board's built-in self-test diagnostics tool that improves the diagnostics accuracy of system board embedded
controller (EC) failures. M-BIST can be manually initiated before POST.
NOTE: M-BIST can be manually initiated before POST(Power On Self Test).
How to run M-BIST?
M-BIST must be initiated on the system from a power-off state that is 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 thepower button that is held down, the battery indicator LED may exhibit two states.
a. OFF: No fault detected with the system board.
b. SOLID AMBER: Indicates a problem with the system board.
L-BIST
L-BIST (LCD Power Rail Test) is an enhancement to the single LED error code diagnostics and is automatically initiated during POST. LBIST 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 an error code [2,8].
NOTE: If L-BIST fails, LCD-BIST cannot function as there is no power being supplied to the LCD.
Running the L-BIST
1. Press the power button to start up 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 [2,8], there is a
failure on the LCD power rail of the system board, hence there is no power supplied to the LCD.
3. Replace the system board in this case.
System diagnostic lights
Battery-status light
Indicates the power and battery-charge status.
Solid white — Power adapter is connected and the battery has more than 5 percent charge.
Amber — Computer is running on battery and the battery has less than 5 percent charge.
Off
• Power adapter is connected and the battery is fully charged.
• Computer is running on battery and the battery has more than 5 percent charge.
• Computer is in sleep state, hibernation, or turned off.
The power and battery-status light blinks amber along with beep codes indicating failures.
For example, the power and battery-status light blinks amber two times followed by a pause, and then blinks white three times followed by
a pause. This 2,3 pattern continues until the computer is turned off indicating no memory or RAM is detected.
The following table shows different power and battery-status light patterns and associated problems.
