Ok soo the past like couple months i have left my macbook pro on overnight because i was downloading stuff so when i woke up in the morning it would be all finished or have a good chunk downloading. So in the morning when i go to it the screen is blank and all i have to do is run my finger over the trackpad and it comes to life or occasionaly i think i had to press the spacebar on a couple of times. Anyways to my question, the last two mornings when i put my finger along the trackpad or hit the spacebar nothing happened it was stil a dark screen. In fact i pressed every button on the keyboard and nothing happened. And i believe it hadn't shut down because i can still hear it inside working. I have no clue what happened as i havent changed anything to my knowledge.So any help as to why it is doing this would be much appreciated.And i can rovide further info if needed
