1st time I've had to send my new 15" MBP for service. I'm a network engineer by trade....and was even using it this morning. The place I was working was a bit staticy...and I guess I fried my ethernet port. Everything else works fine, including airpot. But my trade job...I am constantly plugging in via hard line. So just short of running Super Duper, any do or don'ts on what I should do before I send it in. Do I include my battery, or even document any damage-non damage of the unit prior to sending it in ?
