Hello guys, I am currently using the late 2011 MBP 15' and have recently bought a Crucial M4 SSD. I used carbon copy cloner to copy my whole OSX over from my HDD to my SSD. After setting my SSD as my boot drive and placing it into my MBP, it booted nicely without any problem. However, when I leave my MBP on its own through out the night, it cannot be woken up the next morning. The backlit of the keyboard is still lighten but the screen is just blank. It has happened for the past 2 days and I was forced to force restart in both occasions. Does anyone know the solution to this problem? Any help would be greatly appreciated!
