Safety instructions
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.
NOTE: 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.
NOTE: 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
1
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.
Before working inside your computer
To avoid damaging your computer, perform the following steps before you begin working inside 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 fix the problem yourself, service and support personnel can use the diagnostics results to help you solve the
problem.
Topics:
• Enhanced Pre-Boot System Assessment — ePSA diagnostics
• Device status lights
• Battery status lights
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:
may cause invalid results or error messages.
Use the system diagnostics to test only your computer. Using this program with other computers
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.

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.
Turns on when you turn on the computer and blinks when the computer is in a power management
mode.
Turns on when the computer reads or writes data.
Turns on steadily or blinks to indicate battery charge status.
NOTE: Refer to the following table for Battery charge LED indicator codes.
Turns on when wireless networking is enabled.

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
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 off 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
