My fiancee just had an odd problem start with her MBP a couple days ago. When she closes the screen to transport her laptop and then reopens the screen it doesn't come out of sleep mode properly. I thought at first it was simply staying in sleep mode but you can hear the sounds when you press any keys so I think the computer itself is out of sleep mode but the screen stays dark. The only way we can fix it is to hold down the power button a few seconds to turn the computer off and restart it. I thought it was a one time thing but it has happened every 5 or so times she's closed her laptop the last couple times. Any idea what's causing this? She hasn't made any changes with software or hardware lately and is using the latest Leopard 10.5.2 and all patches.
