Blinking wireless LED in Elitebook 8440p

[Bruno Martins]

Hey list,

I have recently acquired an HP Elitebook 8440p machine and I am facing a 
very strange problem that is: sometimes (randomly) my wireless LED 
starts blinking.
Red and blue (as an on/off switch) but network connectivity is not 
affected, it's just the LED blinking...

My system:

Is there anything I can do to troubleshoot this issue?
