There is a huge crack on the back of my parents Sony Vaio Fit laptop, on the bottom right. Every time I touch it or try to fix it, there is a big pop noise that makes me very nervous. When I try to close it slightly, wires and the inside of the laptop show, and I think if I close it any further, the whole hinge will pop off or the screen will crack or something. Please help! I also have another crack on the other side, but thats minor. I can link photos if you need. And there is a squeaking sound that comes from the laptop 10 seconds after its turned off. I searched it up and its called coil whine, and I need to know if its major and how to fix it. I'm just really nervous because this is my parents laptop and the only one I'm using (until I fix my other one with a SMART hard drive error) and it has all my personal info on it. Thanks!
