Hi. I have a problem that I first noticed yesterday. Whenever I would press the half moon standby button on my keyboard, my computer would go to sleep. I also have a shortcut on my desktop configured to put my computer into hibernate. But now whenever I try to put my pc in sleep or hibernate mode, my monitor goes black for a few seconds but then comes back on at the login screen.

I haven't installed or changed anything other than create a couple logical partitions in the hfs+ filesystem. (still in the process of trying to triple-boot)

Any help would be great, but for now I'm going to bed. Will check back in the morning.
