I got my powerbook 12" about two weeks ago. Yesterday a got an Airport EX card, I removed the battery and opened the little door and grabbed the little white tab holding the AP wire and pulled it out and the connector came off the end of the wire!!! I called apple and they said it was My problem and it would take a Logicboard replacement costing $955 bucks. Now I looked up the take apart manual and that wire is not even close to the logicboard. I'm not happy. Anyway, input??
