I get this same problem too. I have mac calling me tomorrow too. Did you have windows set as default operating system on start up? I had to hold down the power button to power off. When I powered up again it booted into windows. This is what makes me think i had windows set as default. I get the same problem when booting in OS X about you encountering a problem.
Question, when you put it into sleep mode....was it in OSX? Mine was....I wonder if we need to keep OSX default.
