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: 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.
NOTE: The color of your computer and certain components may appear differently than shown in this document.
To avoid damaging your computer, perform the following steps before you begin working inside the computer.
1. Ensure that your work surface is flat and clean to prevent the computer cover from being scratched.
2. Turn off your computer (see Turning Off Your Computer).
CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the
cable from the network device.
3. Disconnect all network cables from the computer.
4. Disconnect your computer and all attached devices from their electrical outlets.
5. Press and hold the power button while the computer is unplugged to ground the system board.
6. Remove the cover.
5
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.
Turning Off Your Computer

CAUTION: To avoid losing data, save and close all open files and exit all open programs before you turn off your
computer.
1. Shut down the operating system:
– In Windows 7:
Click Start , then click Shut Down.

– In Windows Vista:
Click Start , then click the arrow in the lower-right corner of the Start menu as shown below, and then
click Shut Down.
– In Windows XP:
Click Start → Turn Off Computer → Turn Off . The computer turns off after the operating system shutdown
process is complete.
2. Ensure that the computer and all attached devices are turned off. If your computer and attached devices did not
automatically turn off when you shut down your operating system, press and hold the power button for about 6
seconds to turn them off.
After Working Inside Your Computer

After you complete any replacement procedure, ensure you connect any external devices, cards, and cables before
turning on your computer.
1. Replace the cover.

CAUTION: To connect a network cable, first plug the cable into the network device and then plug it into the
computer.
2. Connect any telephone or network cables to your computer.
3. Connect your computer and all attached devices to their electrical outlets.
4. Turn on your computer.
5. If required, verify that the computer works correctly by running the Dell Diagnostics.

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.

2. As the computer boots, press the <F12> key as the Dell logo appears.
3. On the boot menu screen, select the Diagnostics option.
The Enhanced Pre-boot System Assessment window is displayed, listing all devices detected in the computer. The
diagnostics starts running the tests on all the detected devices.
4. If you wish to run a diagnostic test on a specific device, press <Esc> and click Yes to stop the diagnostic test.
5. Select the device from the left pane and click Run Tests.
6. If there are any issues, error codes are displayed.
Note the error code and contact Dell.
