Working on your computer

Safety instructions

Use the following safety guidelines to protect your computer from potential damage and 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 the reverse order.

WARNING: Disconnect all power sources before opening the computer cover or panels. After you nish 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 certied 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 that is grounded to ground yourself before you touch the computer to perform any

disassembly tasks.

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 dierently than shown in this document.

Before working inside your computer

To avoid damaging your computer, perform the following steps before you begin working inside the computer.

the network device.

5. Disconnect your computer and all attached devices from the electrical outlets.

6. Press and hold the power button while the computer is unplugged to ground the system board.

NOTE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching

an unpainted metal surface at the same time as touching a connector on the back of the computer.

Turning o your computer

CAUTION: To avoid losing data, save and close all open les and exit all open programs before you turn o your

computer.

NOTE: Press and hold the power button for ve second to force-shutdown the system.

CAUTION: A force-shutdown can hose up Windows or even lead to data loss.

2. Ensure that the computer and all attached devices are turned o. If your computer and attached devices did not automatically

turn o when you shut down your operating system, press and hold the power button for about 6 seconds to turn them o.

After working inside your computer

After you complete any replacement procedure, ensure that you connect any external devices, cards, and cables before turning on

your computer.

CAUTION: To avoid damage to the computer, use only the battery designed for this particular Dell computer. Do not use

batteries designed for other Dell computers.

1. Connect any external devices, such as a port replicator or media base, and replace any cards, such as an ExpressCard.

2. Connect any telephone or network cables to your computer.

CAUTION: To connect a network cable, rst plug the cable into the network device and then plug it into the

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 x 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 specic devices require user interaction. Always ensure that you are present at the computer

terminal when the diagnostic tests are performed.

Device status lights

Table 1. Device status lights

Icon Name Description

Power

status light

Turns on when you turn on the computer and blinks when the computer is in a power management

mode.

Hard drive

status light

Turns on when the computer reads or writes data.

Battery

charge

indicator

Turns on steadily or blinks to indicate battery charge status.

The device status LEDs are usually located either on the top or left side of the keyboard. They display the storage, battery and

wireless devices connectivity and activity. Apart from that they can be useful as a diagnostic tool when there's a possible failure to

the system.

NOTE: The position of the power status light may vary depending on the system.

The following table lists how to read the LED codes when possible errors occur.

Amber blinking pattern Problem description Suggested resolution

2,1 CPU CPU failure

2,2 System board: BIOS ROM System board, covers BIOS corruption or ROM error

2,3 Memory No memory/RAM detected

2,4 Memory Memory/RAM failure

2,5 Memory Invalid memory installed

2,6 System board: Chipset System board/Chipset error

2,7 LCD Replace the system board

3,1 RTC Power Failure CMOS battery failure

3,2 PCI/Video PCI or video card/chip failure

3,3 BIOS Recovery 1 Recovery image not found

3,4 BIOS Recovery 2 Recovery image found but invalid

The blinking patterns will consist of 2 set of numbers being represented by (First Group: Amber blinks, Second Group: White blinks)

NOTE:

1. First Group: The LED blinks 1 to 9 times followed by a brief pause with LED o at the interval of 1.5 seconds.(This is in

Amber color)

2. Second Group: The LED blinks 1 to 9 times, that would be then followed by a longer pause before the next cycle starts

again at the interval of 1.5 seconds.(This is in White color)

For Example: No Memory detected (2,3), Battery LED blinks two times of amber color followed by a pause, and then blinks three

times of white color. The Battery LED will pause for 3 seconds before the next cycle repeat itself again.

Battery status lights

If the computer is connected to an electrical outlet, the battery light operates as follows:

Alternately blinking

amber light and

white light

An unauthenticated or unsupported non-Dell AC adapter is attached to your laptop. Re-plug battery

connector, replace battery if the issue reoccurs.

Alternately blinking

amber light with

steady white light

Temporary battery failure with AC adapter present. Re-plug battery connector, replace battery if the issue

reoccurs.

Constantly blinking

amber light

Fatal battery failure with AC adapter present. Fetal battery, replace the battery.

Light o Battery in full charge mode with AC adapter present.

White light on Battery in charge mode with AC adapter present.
