for about ten minutes now, ive got a horizontal whitle line right in the middle of my laptop display. it goes across the whole thing. It's exactly one pixel wide. It's not directly white, but it seems to be always a few shades lighter then the rest of the screen (black->grey, grey->white)
I had a similar problem a few years ago, but then the line was -vertical, -darker not lighter and -about 5cm wide.
Back then I had to send it it to get repaired. Please tell me it's a software thing this time!!
