I just recently migrated to the new 12" 1ghz powerbook and I'm trying find out how to shut off the lcd without putting the entire computer to sleep. From the keyboard, it would seem like command-f7 should turn off the display but it doesn't. Actually, command-f1 doesn't lower the brightness either so my recent reinstall of OS X might have done something to it. I hope somebody can help me because I might just migrate straight back to windows if this crucial feature isn't available. Right now, I'm making due with just changing the energy saver settings to turn off the display after a minute of inactivity.
