Before working inside your
computer
NOTE: The images in this document may differ from your computer
depending on the configuration you ordered.
Before you begin
1 Save and close all open files and exit all open applications.
2 Shut down your computer.
Windows 10: Click or tap 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 cables such as telephone cables, network cables, and so on,
from your computer.
5 Disconnect all attached devices and peripherals, such as keyboard, mouse,
monitor, and so on, from your computer.
6 Remove any media card and optical disc from your computer, if applicable.
7 After the computer is unplugged, press and hold the power button for 5
seconds to ground the system board.
Safety instructions
Use the following safety guidelines to protect your computer from potential
damage and ensure your personal safety.
WARNING: Before working inside your computer, read the safety
information that shipped with your computer. For more safety best
practices, see the Regulatory Compliance home page at
www.dell.com/regulatory_compliance.
12
WARNING: 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 electrical outlet.
CAUTION: To avoid damaging the computer, ensure that the work
surface is flat and clean.
CAUTION: To avoid damaging the components and cards, handle
them by their edges, and avoid touching pins and 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 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 on its connector or on
its pull tab, not on the cable itself. Some cables have connectors with
locking tabs or thumb-screws that you must disengage before
disconnecting the cable. When disconnecting cables, keep them
evenly aligned to avoid bending any connector pins. When
connecting cables, ensure that the ports and connectors are correctly
oriented and aligned.
CAUTION: Press and eject any installed card from the media-card
reader.

Enhanced Pre-Boot System Assessment
(ePSA) diagnostics
CAUTION: Use the ePSA diagnostics to test only your computer.
Using this program with other computers may cause invalid results or
error messages.
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: 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.

System diagnostic lights
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 in amber color during the start-up.
The following table shows different light patterns and what they indicate.
