Need to investigate.

I was reading through the documentation sent with my son's computer and noticed a couple of points that I need to investigate. I realized that the computers assigned to us by the school were obviously school property. What I didn't realize was that anything that happens to them is our responsibility. I guess I just assumed that the school would have some type of laptop insurance on the computers given that they were being handed out to very young students. I am now wondering if this is something that we need to look into obtaining on our own? I have no idea how you go about doing this or if it is even possible. I would have to think that if a power surge hit our house that we might be paying out of pocket for two high end laptops.
