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.
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: 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 specic devices require user interaction. Always ensure that you are present at the computer terminal
when the diagnostic tests are performed.
You can launch the ePSA diagnostics in two ways:
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 displays, 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 specic 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.
OR
1 Shutdown the computer.
2 Press and hold the fn key, while pressing the power button, and then release both.

Table 8. Device status lights
Icon Name Description
Power

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

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)
Diagnostics 95
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.
Alternately blinking
amber light with
steady white light
Temporary battery failure with AC adapter present.
Constantly blinking
amber light
Fatal battery failure with AC adapter present.
Light o Battery in full charge mode with AC adapter present.
White light on Battery in charge mode with AC adapter present.

Troubleshooting
Dell Enhanced Pre-Boot System Assessment — ePSA
diagnostic 3.0
You can invoke the ePSA diagnostics by performing either of the following steps:
• Press the F12 key when the system boots and choosing Diagnostics option.
• Press Fn+PWR when the system boots.
For more details, see Dell EPSA Diagnostic 3.0.
Running the ePSA diagnostics
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.
4 Click the arrow key at the bottom left corner.
Diagnostics front page is displayed.
5 Press the arrow in the lower-right corner to go to the page listing.
The items detected are listed.
6 To run a diagnostic test on a specic device, press Esc and click Yes to stop the diagnostic test.
7 Select the device from the left pane and click Run Tests.
8 If there are any issues, error codes are displayed.
Note the error code and validation number and contact Dell.
LAN status LED
The RJ-45 connector includes two LEDs in the top corners. When the connection is oriented as shown below, the LED in the top-left
corner is the link integrity LED and the one in the top-right corner is the network activity LED.
The link integrity LED can display three colors: green, orange, and yellow. These colors indicate the three possible network connection
speeds: 10 Mbps, 100 Mbps, and 1000 Mbps, respectively. These LED states are shown in the image below. The network activity LED is
always yellow and blinks to indicate passing network trac.
The LAN controller supports two status LEDS. A link LED displays the current transfer rate supported (10, 100, or 1000Mbps), while the
activity LED indicates when the card is receiving or transmitting data. The following table illustrates the LEDs' operation.

Real Time Clock reset
The Real Time Clock (RTC) reset function allows you or the service technician to recover the recently launched model Dell Latitude and
Precision systems from select No POST/No Boot/No Power situations. You can initiate the RTC reset on the system from a power o
state only if it is connected to AC power. Press and hold the power button for 25 seconds. The system RTC reset occurs after you release
the power button.
NOTE: If AC power is disconnected from the system during the process or the power button is held longer than 40 seconds, the
RTC reset process is aborted.
The RTC reset will reset the BIOS to Defaults, un-provision Intel vPro and reset the system date and time. The following items are
unaected by the RTC reset:
• Service Tag
• Asset Tag
• Ownership Tag
• Admin Password
• System Password
• HDD Password
• Key Databases
• System Logs
The following items may or may not reset based on your custom BIOS setting selections:
• The Boot List
• Enable Legacy OROMs
• Secure Boot Enable
• Allow BIOS Downgrade
