Working on your computer
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: System will shut down if side covers are removed while the system is running. The system will not power on
if the side cover is removed.
CAUTION: System will shut down if side covers are removed while the system is running. The system will not power on
if the side cover is removed.
CAUTION: System will shut down if side covers are removed while the system is running. The system will not power on
if the side cover is removed.

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.

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
• Other Options:
• BIOS Setup
• BIOS Flash Update
• Diagnostics
• Change Boot Mode Settings

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 Dell EPSA Diagnostic 3.0.
Running the ePSA diagnostics

Diagnostic LED
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.
NOTE: The diagnostic pattern consists 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.
