CALL APPLE!!!
Unless you are taking to an Apple store (one of the ones that recently opened up) do NOT take it to anyone. CALL Apple FIRST. They will have you check a few things and then, if necessary, send you a shipping box. IF you take it to someone else, you are looking to extend the time you are without the laptop by at least another day or more. Apple sends you an Airborne Express box, you pack up the laptop, call Airborne who then comes and picks it up (same day). Apple gets it the next day (business day), repairs it and sends it back to you for the following day. That is, unless they are out of parts. There is a good chance they will send you a part, if it is on the list or customer/user replaceable/installable items.
