Sometimes after I logoff, I'll close the lid on my MBP. I always wait until I'm fully logged off before I do this. Later when I want to use my computer I open the lid, the keyboard backlight comes on, but I get no picture on the screen. If I take the machine into my office and connect it to my external monitor, I get no picture there either. The only way to get my computer back is to hold down the power button until it turns off and then turn it back on. Has anyone seen this issue? If so, do you know of a solution? I don't think it's been doing this since I bought it. It seems like it's been worse since the latest OS X patch, but I could be mistaken.
