In each call I talked to the service technicians. I asked for a price quote on labor and the parts to fix the "infamous macbook whine". I told them I have a Macbook I bought it in November 2006. All three places were not sure about the Macbook whine and told me it can from the power cord area, fan or logic board. One of these three should be replaced. What surprises me they all were dumbfounded when I mentioned the Macbook "whine". It seemed to me like they were never heard of that before and I am the first one to talk to them about it. I do know the newer laptops don't have this issue. It just surprises me that the local Mom and Pop Mac resellers don't know much about this. The average price to fix the logic board if that was the issue was $380. Not sure if that is too much money or not. I guess I better to ifixit.com and see if fixing it myself would be a better deal.
