This is has been occurring most every night since I've had this MBP for a few weeks. I put the MBP to sleep at night. Then some point in the morning, I can actually hear it wake, but then quickly, within 5 seconds, it right back to sleep. I have no programs telling it to awake or perform scans, my Bluetooth mouse is off, etc. Has anyone experienced this or know how to resolve it? Thank you.
