Today I discover that my MB and the attached strips are turned off. I don't remember if the problems are due to update of the bios, aura sw or AI Suite, but now I don't have no more light on. Only Video card and memory works.
I already check the configuration in the bios and the options are already enable. I notice that if I remove the power cord and then reconnect, turning on the pc, the light on the motherboard turn on for a fraction of second.
