Just got a new MBP 2.4 Saturday night. After 30 minutes the power supply starting humming and then popped. Luckly I was still running on battery power. On Sunday's in Northern NJ the stores are closed so I couldn't get a new one. But this morning I called every Apple store in the NYC metro area, and not one has a new power adapter in stock. So I got to enjoy the MBP for an additional 2 hours. But waiting and searching for an adapter is painful. And yes I've tried every trick on the forums to get it running and called Applecare.
