I have a one-month old Macbook Pro. It was accidentally left unplugged last night (the plug was loose in the socket and fell out), and it was open with a program running so it didn't go to sleep and the battery completely died. I plugged it back in, and now it looks like this: The problem is that the progress bar stopped moving about 2 hours ago, and is stuck in the same place. Is this bad? Did I kill it?
