I just picked up a refurb 750JZ and immediately after the raid screen, there's a black screen with some red symbols over what appears to be a blue bar, on the very top portion of the screen. I've read one other person in the forums that had this same issue. Doesn't seem to hurt anything, but you'd think on a high end laptop, it wouldn't be released like this. I contacted Asus and sent it back under warranty once, they said they fixed the problem, they told me in s chat that it was a LCD cable issue, the paper in the box said it was a software issue, so clearly they are blowing smoke somewhere. Just curious if anyone else has this issue, or if I should send it back in again. Thanks!
