Spontaneous Keyboard Destruction?

I had a laptop in for diagnostics the other day. The client stated that the keyboard had suddenly popped from it mounting and then refused to boot. Upon removing the keyboard I noticed that it was quite bent. The motherboard, mounting plate and switch circuit board have both been damaged. It appears as though someone had smashed both fists into it in a fit of rage. I questioned the owner and he seemed to have no idea how it occured.

Yeah right.
