I just setup a Bootcamp Windows 7 Ultimate partion on my 13'' MBP. When I click on the orb, I see the power off and hibernate options; the 'sleep' option is greyed out. In 'Power Options', the sleep option is fully ommitted. If I close the lid of the machine it goes enters hibernation. Any way to fix this? I've seen some threads on the Apple support site about users reporting similar problems.
