Comment 4 for bug 224098

@nico008 - Couldn't say. Since it tends to blink even though you're in Linux, I would tend to think that it was a hardware link to the wifi card. I have never owned a laptop so I don't really know if there would be a separate connector for it in there or not. But then again it is possible that you wifi drivers control the light. If so, there may be a way to configure it's behaviour if you investigate the driver package. If it were part of the keyboard controller, I would imagine that it would just stay dark. I wonder if you can control that light in Windows. If so, the place in Windows where you gain control over it's behavior might give a clue. I really doubt it is managed by the keyboard controller, though, if it is blinking under Linux now. It might be a good idea to open a separate bug report categorized for your wifi driver package.
