Yes, the laptop HDDs do rattle. Every manufacturer will give slightly different reasons why, but it is not the problem here. To best determine if the LCD is bad,, there is most likely a VGA output on the laptop. If you hook it up to a monitor and the laptop outputs to it, there is probably an issue with the lcd or cabling. You may have not reseated it properly or the connector is loose. If it still does not output to a monitor then you may have a prob with the video card and that would be part of the motherboard.
i am no lazier now than I was forty years ago, but that is because I reached the limit forty years ago. You can\'t go beyond possibility.
