Today my 2011 mbp black screened upon restarting. Its still stuck on the black screen every time i turn it on. The chime still goes off and the screen turns on (its stll black but differen than it would be if its off). All the keys other than the power button are unresponsive. The keyboard backlight doesnt turn on nor does the Caps Lock button. I was attempting to boot into windows 7 partition when this started. I think its somehow stuck between windows and osx. I also opened the bottom of my unibody abd everything appears normal. Nothing appears melted and the fan turns on. I had the battery changed a month ago. The battery was swollen but after replacement the laptop operated normally.
