I have an MSI Z68-GD55 G3 mainboard and my LED phase lights stopped blinking. They do not turn on anymore. Should I be concerned or is this normal? Everything on my computer seems to work perfectly.
 
My Gigabyte motherboards also have phase lights on them. They do not tell me anything useful. I ignore them.

There's a Windows based power utility that reportedly uses them. Because it doesn't do anything I need, I don't install it.
