Latitude 7480, 2 amber lights 4 white lights

Hello guys,

I read over some posts about another series laptop also being affected with this,found a method that consists to connect it to a external display (docking's monitors are valid) and worked good,video shows.

This morning i had the same issue and external displays aren't resolving the situation.

The motherboard was replaced some months back..

is someone with this issue on Latitude 7480?

The 2 amber lights followed by 4 white lights on a Dell Latitude 7480 indicates a RAM/Memory Failure.

Here are some steps to try:

1. Reseat the Original Memory: If applicable to your model, reseat the original memory module in the system. Sometimes, reseating the RAM can resolve the issue.

2. Check for Damaged RAM: If reseating the RAM doesn’t work, consider checking for any visible damage to the RAM sticks. If they appear damaged, you may need to replace them.

3. Firmware Updates: Ensure that your system’s firmware (BIOS) is up to date. Sometimes, updating the firmware can resolve hardware-related issues.

Thanks for this! I had the same 4 White/2 Amber blink code on a 7480 as original poster and re-seating the ram and doing firmware updates cleared up all my issues.

@JessWong666 those codes are uniform across the last few generations of Latitudes.

To get an accurate diagnostics sequence it's recommended that you try a diagnostic boot by holding down the Fn key and powering on the system. The system will then flash the power button in sequence to advise what fault its encountering.

Blinking Pattern

Possible Problem Problem Description

Same, when I was able to get the computer back on I went ahead and did the diagnostic F5 choice when it started the memory test the screen produced black and white lines and once again locked up. 

I will buy two new RAM sticks to see if this solves this problem and let you know

Sorry, I actually have 2 amber lights and 5 white lights. Does it mean the memory (RAM) is broken and I need to change the memory (RAM)?

Hi, I have the same problem. However, after trying to reseat the memory (RAM), i.e. taking out the RAMs and putting them back in the slots, the problem persist. Any advice how to solve the issue?
