whining MacBook Pros since the release of the product. MacBook Pro user Rickard Almqvist sent in his MBP for some repairs and got it back with a new logic board and a friendly letter from Apple letting him know what was up. The new version of the logic board requires OS X 10.4.6, as opposed to the machine's original 10.4.5, so they included some new install DVDs in case he needs to reinstall. After the upgrade he hasn't had any whining problems, and he, along with other users with similar reports, is attributing it to the new board. No word yet if Apple will offer this upgrade to users who merely complain of the whine, or if you'll need a more serious problem to crop up before they'll do the swap-a-roo, but it does look like there's hope on the horizon beyond just buying a new revision of the troublesome laptop.
