Working on Your Computer
Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential damage and to help 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.
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 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 at www.dell.com/
regulatory_compliance
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, such as 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.

Diagnostics
If you experience a problem with your computer, run the ePSA diagnostics before contacting Dell for technical
assistance. The purpose of running diagnostics is to test your computer's hardware without requiring additional
equipment or risking data loss. If you are unable to fix the problem yourself, service and support personnel can use the
diagnostics results to help you solve the problem.
Enhanced Pre-Boot System Assessment (ePSA) Diagnostics
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
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.
1. Power-on the computer.
2. As the computer boots, press the <F12> key as the Dell logo appears.
