Sony Vaio laptop turns on/off by itself?

Just for reference, I own a (rather old) Sony Vaio which has Windows 7. For nearly a week now, every night at around 3 or 4am my laptop will turn on by itself while it's still closed and then shut off after a few minutes. Since the sound of the fan is pretty loud it always wakes me up as my laptop sits right next to my bed. Any idea as to what could be causing this besides the possibility that my house is haunted? lol
