So I'm pretty sure my brother in law sabatoged my laptop before moving out of state. There was nothing wrong with it, then the next time I took it out the whole screen was broke. It looks like someone tried to snap it in half, even the plastic frame has a crack right in the middle of it. So when I turn it on I see all the cracks and a bunch of black marks but behind that I can still read what is in the screen on the parts of the screen that aren't broken. So my question is what part of the screen do i actually have to replace? Do I need to replace the glass and lcd or Just the glass? How can I tell?
