Before you begin
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.

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.
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.
12
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
The ePSA diagnostics (also known as system diagnostics) performs a complete check

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
CAUTION: Use the system diagnostics to test only your computer. Using
this program with other computers may cause invalid results or error
messages.
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.
