Okay, something really bizarre just happened...
I had my brother's macbook cord in my computer. The cord just snapped, and my computer spontaneously shut down. I did manage to turn it back on, but now when I do there's a black X in the battery symbol and I know it can't mean that my battery's not working. It also says whenever I turn on the computer that the date is set before Jan. 1st 2008, even though when I check preferences it says I have the right date. It also seems to have forgotten my network preferences.
My brother's mad at me for breaking his cord even though I didn't do a damn thing, and he tried to put the cord BACK IN MY COMPUTER even after what happened. What a moron.
Help? WTF just happened?
