Apple cancelled my warranty and will not fix computer!

You will have to resolve this through AppleCare. These discussions are user-to-user discussions, and we cannot help you with warranty issues. Call AppleCare and speak to a person in Customer Relations.

If your computer sustained damage as a result of your negligence, then repairing that damage is not covered by the warranty. It may help you further to read the warranty that came with your computer.

Scubagirl12,
How have you packed the machine? If it bumped against anything hard, or heavy books were against it for prolonged period of time, or it was against a seat inside a backpack, that might have damaged it if it wasn't properly padded. If none of those describe the problem, and you've always pulled your cables out properly* as described below:

Call 1-800-APLCARE, and tell them you believe your machine was manufactured with the screws too tight or loose, and it was only noticeable after prolonged use, and believe they should fix the case at their cost if your machine is under a year old, or you have purchased AppleCare, and it is less than 3 years from date of the computer's purchase. If you are beyond AppleCare, (either first year, or purchased 3 years from date of computer's purchase), and purchased by credit card, and believe the case was never the right tightness to begin with, sometimes your credit card prolongs warranty, and you can ask them.

If none of the above seems to help you, and there was a possible heavy bump, or improper cable disconnection, unfortunately only your homeowners insurance might cover it, if it has accident protection. Warranty does not equal insurance. Above all, be calm when talking to all of them.

Good luck. This is a user to user board, and we can't speculate on how Apple will rule in your case. But just letting you know what options may or may not help you.

Go through these discussions and you will find other examples of Mac Book cases that have deteriorated and cracked with no evidence of hard impact AND Apple has agreed to fix or replace the defective parts for machines even out of warranty.

Print out what you find and bring them to the Apple location. Be firm but cool and insist on service to an Applecare covered machine that you paid extra to insure against defects or failures.
