From in above page/form you may ask, including Estimates,
& add details. According to your location, and Mac's needs.
Other possibilities may include scheduling a visit to an Apple
Retail Store Genius. They could be able to estimate hardware
costs and arrange to have the product repaired. Usually at an
authorized factory repair depot, or an Apple service center.
[The above Support page also includes small blue text links
to more information; those may be worth reading for detail.]
Some regions have a longer warranty, or consumer laws to
cover repair. Where customary those may be more than one
year. Some such as EU or UK, have different rules than USA.
