I was just on my MacBook Pro just web browsing and with around 50% battery life left it just shut off without warning or anything. I tried to turn it back on and it was unresponsive. I plugged it into the outlet and the green light on the plug didn't turn on and the computer is still un responsive. It is not even 2 years old and I don't mistreat it. It barely leaves my desk. What happened! I'm freaking out over here and need to know it will be ok. Thanks.[
