I too have this problem. However this also happens when my PC (Win 7) is turned off.
My Book Live goes in to stand-by (blue light), then randomly it turns ons (greens light), even if my PC is off.
As Markvm has said ‘I don’t want this, because like I said it’s not in use at that time.’
I have only had my MBL for about a week, so still in the process of getting use to it.
I must come clean and say that I’m a bit of noob, and new to all this networking stuff, so thought this was the way it is, but it annoys me. After reading this thread, I believe that it is not normal.
Any ideas???
Also as another thing, when it does go to stand by (blue light), there is still a slight noise, and if I put my hand on the side of it can feel slight vibration, as if the discs ars still spin( all the time)…normal???
Like I say I am a noob so may just be abit paranoid
