I read this thread on the apple forums:
http://discussions.apple.com/thread.jspa?threadID=461079&tstart=60

I followed the instructions and I have no whine..... might be worth a shot to some of you out there instead of running the QuietMBP in the background.

I didn't see the author, and I thought this would be one of those topics where somebody yells at us for trying to fix our MBP whines. Usually coming from a guy who complains about a scratch on his iBook's underside.

Thanks for the link though! If (after my MBP is sent away for repair) it still buzzes, I'll try this.
 
Only downside currently is that it takes a little longer to boot, but I always sleep my system so that is not a problem. There is another thread on there that has pointed out the cause of the whine problem. It is far more technical then what I can understand, so I don't know what really to make of it.
 
I posted this in another thread. If you open photobooth and then force quit, the noise is goes away. That's what I've found works the best.

I should note that this only works until you use the iSight camera again unless you force quit whatever program uses the iSight after you're done.
 
This fix is magic.

Seriously.

I've never owned a computer this quiet. I can't hear a thing. It's...amazing :) .
 
After updating the keyboard fix from apple, the photobooth or comic open/close trick did not work for me. After using this trick, it definately fixed it and haven't heard any whine at all. It looks like apple has not made any specific drivers for power management for the MBP, so if you can live with a little longer boot time try the fix out! I hope for Apple to make it a permanent fix eventually.

If it makes you guys feel any better my dell whines to and it's only a single core centrino.

Even nicer to know that the whine is software based.

My take is that it is probably hardware based. Other desktop systems using the same chipset and processors are not affected by the whine, only the MBP..
 
Wouldn't that mean it's software based? Since Apple is using the same components as everyone else (read: Intel), and there's no whine in Windows? (at least none that I have heard about).

I don't think so.

Apple is only using the same CPU and chipset as everyone else. The rest of the componentry on the motherboard is custom. That's where the hardware problem is.

If it was a software problem, it's likely that iMacs and minis would be displaying the same problems, but they aren't.

As it stands, I strongly believe it is a hardware problem specific to the MBP.

I've posted a file which will allow people to go back to using the Mirror widget hack, which recently broke with Apple's 'Keyboard Update'.
 
I just updated the keyboard fix as well, and now the photobooth/comic life fix does not work. Is there anyway I can uninstall the update at all?? id much rather deal with the issue than have to hear the whine no matter what.

It's software (assuming the same cause for everyone). It doesn't happen when the MBP is running Windows, or for at least some users, OS X 10.4.5.

It's hardware-specific, yes, but it's not faulty hardware that's causing the whine. It's faulty software written for that hardware...evidenced by the fact that the MacBook Pro doesn't whine in Windows XP at all.

Also, the iMac doesn't need as aggressive power management...which would make it less likely to make the "whine"...and 3.5" drives are usually louder.

The power management software in OSX is more aggressive than Windows XP (as people have reported shorter battery life in XP). The fact that the hardware cannot cope with the more aggressive power management without emitting noise, makes it a hardware problem.

See my post 2 messages above yours.

How so? Several users running 10.4.5 also report the noise going away. It's entirely possible the power management software is faulty, having nothing to do with the hardware's ability to "cope"...the difference between XP and OS X does not inherently call for any higher or lower tolerances, as both comply with standard industry designs.

The reason the problem is specific to the MBP is because it's the result of the way the OS attempts to save power when it's not needed. In many cases, the whine is only present (or is much worse) when the MPB is running on battery power.

I wouldn't get too excited about this fix, from what I've heard it cuts battery life significantly. Those of you who have tried it, how is your battery life after the hack?
