Hello everyone. This is my first post. I've been reading this board for a while. I need your help. I'm having some issues with my macbook (white 1.83ghz). Listed are the issues that I'm experiencing. *When I plug the power cord into the computer, the computer turns on by itself. I do no push the power button. *The screen flickers when the computer is being used. Not all the time, but this happens often. *The computer battery is bulging (battery has a bump). The computer bottom should be flat. Mine isn't. *The battery is dead. Will not charge. Is this normal? This happened two years ago. Haven't gotten a new battery. Now, I've had this system for around three years. I fear that my computer might be a lemon. Wondering what apple can do to help me out? What do ya'll suggest? Thanks for your help.
