Do they notice this when repairs in the media market?

I've damaged my laptop display ever since it flaked

(I accidentally threw something at that)

Can I have the laptop repaired under warranty?

I think that would work because there are no signs that I was to blame

Would that work?

No, that doesn't work! The experts know and notice such things!

Well, if you've thrown a stone against it, you can certainly see it inside, but certainly not with a paper ball.
