I looked on the AW 51m sales portal and looked at the description of the eyes. Here's what I found:
Whether the lights are on or off, the Area-51m’s illuminated Alien eyes are sure to catch attention. Alien eyes will light up in green, blue, and red depending on the current power status of your system.
I haven't received my laptop yet, so I can't confirm the above statement, but maybe it's related to power? Anybody notice that or can test that out?
