New MacBook Pro Logic Board Fixes Whine

It looks like some MacBook Pros that Apple is servicing are receiving a new logic board that eliminates the whining sound owners have been complaining about. A report at Macintouch says that this new main logic board does not include any new features, although it does require a minimum of Mac OS X 10.4.6 instead of 10.4.5. MacBook Pro owners that receive the new logic board also get new Mac OS X installer DVDs.
