I have a macbook air. I accidentally shut it on this studded earring and it caused a little screen damage. What should I do?

Take it into Genius Bar for an estimate. What you did is considered accident/abuse (technical terms) and is not covered by warranty.

Screen replacements can be pricey.

Good luck.

As Steve said, this isn't covered under warranty. But your home owners insurance may cover it and if your deducible is in the $100-$200 range it is worth investigating. When you do, also ask your agent about a 'rider' for your computer (and other electronic devices).

When I queried my agent about insuring my notebook years ago seeing that I had a Treo cell phone she also suggested I add that. Today we cover the notebooks, iPad, and iPhones for a flat $250 a year extra. There is no deductible, full replacement for damage or theft, and the only provision is that they aren't covered if left unattended in a car. I've made two claims: a computer stolen from my locked office and a computer that was destroyed when my car was rear-ended at a stop light. In both cases my agent told me to buy a replacement of equal capability and my rates didn't go up.

I did as dwb advises ... homeowner's extension to cover personal objects. The premium to cover my $1800 MBP is $40 per year. His bill of $250 per year is due to the number of devices.
