I recently got a new laptop from circuit city. the box was half opened when we got it. we exchanged it in for our old laptop because it was no good. now, a week after the new one was bought, the new one's screen looks like it has dead pixels or something. I looked at cracked pictures of laptops on google images and it looks just like ours. Could this have cracked before we got it and then showed up later? We are going to try to return it tomorrow and my question was if it could have been cracked before we brought it home and showed up later. THANKS!
