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.

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.

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

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.

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.

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.

Troubleshooting Your Computer

You can troubleshoot your computer using indicators like Diagnostic Lights, Beep Codes, and Error

Messages during the operation of the computer.

Power LED Diagnostics

The power button LED located on the front of the chassis also functions as a bicolored diagnostic LED.

The diagnostic LED is only active and visible during the POST process. Once the operating system starts

to load, it is no longer visible.

Amber LED blinking scheme – The pattern is 2 or 3 blinks followed by a short pause then x number of

blinks up to 7. The repeated pattern has a long pause inserted in the middle. For example 2,3 = 2 amber

blinks, short pause, 3 amber blinks followed by long pause then repeats.

Amber LED State Description

3,5 memory modules are detected, but a memory configuration or compatibility error

3,6 possible system board resource and/or hardware failure

3,7 some other failure with messages on screen

Beep Code

The computer can emit a series of beeps during start-up if the display does not show errors or problems.

These series of beeps, called beep codes, identify various problems. The delay between each beep is 300

ms, the delay between each set of beeps is 3 sec, and the beep sound lasts 300 ms. After each beep and

each set of beeps, the BIOS should detect if the user presses the power button. If so, BIOS will jump out

from looping and execute the normal shutdown process and power system.
