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?

sergioax,

The diagnostics led's that you are reporting is a Ram Failure. Reseat the memory in the system to see if that will resolve the issue.

The system will not shut down when displaying the diagnostic error codes.

Diagnostic error codes will always supersede any other use of the LED. For instance, on notebooks, battery codes for low-battery or battery-failure situations will not be displayed when diagnostic error codes are being displayed.
