MBP Won't wake from Sleep on 10.8

[Habusho]

Hi, I have a 2011 quad core mac book pro. I'm having a problem where, when I close the lid of my computer to put it to sleep, the computer won't wake when I lift it up again. The only thing that fixes it is a hard reset. The light on the front stays constant when the lid is closed and when I lift the screen the light goes off but nothing else happens. Is there a way to fix this?

Same here

I'm also having the exact same problem.

I've tried a clean install, reseting smc and pram and turning off bluetooth so far to no avail.

Have booked an appointment with a Genius for Sunday.
