Computer wakes and lights come/stay on...

Since the Windows 10 upgrade, my computer seems to be waking up (from sleep mode) after I close and store my laptop over night. Anyone else having the same issue?

Example: My laptop is set to "Sleep" when shutting the lid. Before going to bed, I close the laptop and sit it on the side of my nightstand. When I wake in the morning, the Alienware lights on the outside of the laptop are illuminated, and it appears the keys are lit as well (but not the screen). I can tell the keys are lit by peeking inside the closed laptop without actually opening it.

Any ideas would be appreciated.
