Symptoms: --Keyboard and trackpad intermittently stop responding. Sleeping the machine briefly brings them back. (Unpredictable, has happened almost as long as I've had it) --Built-in iSight camera is not recognized by any program that uses it. Green light never comes on, and PhotoBooth, etc. think no camera is attached. (Since Sunday) --Magsafe power adapter is not charging the battery. No LED lights on the adapter, and the battery indicator in the toolbar says "(Not Charging)." It is, however, providing power to keep the machine going. (Since this morning) My research indicates: --The keyboard/trackpad issue should just require a new topcase. --The camera issue could be a logic board problem or a frayed wire. --The power issues could be a bad battery, or a logic board problem. Conclusions? Do you think I have a bad logic board? Do you think I'll need to send it out to be repaired? I'm a law student with exams starting in two weeks. I canNOT go even a few days without my computer right now. Any advice/etc. would be helpful. I am going to the Apple Store this afternoon to get it looked at, but would like an idea of what I'm facing before I go. Thanks!
