Alienware ACT1250 - GPU Turning on during sleep mode

I purchased the ACT1250 a few months ago and since purchase i have noticed the GPU light and fan kicking on independently of the rest of the system while the rest of the computer is in sleep mode.  This also sends a breif signal to the connected monitors and turns them on as well.  Somewhere between 10 and 20 minutes after going to sleep the GPU cycles on and continues cycling on in seemingly random intervals throughout sleep mode.

Is anyone else experiencing this issue?
