I bought my Macbook about a month ago from a retail Apple Store. They gave me a week 22 and for about the past two weeks, I've been experiencing the whine/moo that people have been talking about with the fans starting up but then not actually starting up. I've been told people have been getting their macbooks replaced due to this, is this true? Should I just call applecare and have them replace it?

could you record it? i REALLY want to hear this moo people are talking about..

anyways, yes if theres a problem with a part that apple cannot replace readily, they will replace the computer. try calling them or taking it into an apple store

<figured it out, serial number?>>


gregor, if your really having those problems id bring it in and make them fix it. its a new computer, you shouldnt have problems

To find the week number: Click the apple in the top left > About this Mac > More info. In the windows comes up, you'll see your serial number. The first 4 numbers, 4HXX: the two XX's are going to be two numbers, that's the production week.

mines 24, is that ok?

08-09-2006, 04:46 PM

I don't think you are correct there, otherwise my MacBook would be production week 62

<edit> yea its the 4+5 digits.. http://www.macnn.com/articles/06/04/...issues.solved/

Sorry, trpnmonkey, it's the 2 digits after the "4H6" or whatever it is there.

Blimey, mine's week 11. No wonder I had issues

Still, got a new keyboard, top case, logic board and hard drive thanks to the guys at the Apple store so all should be well now.

mine has moo'd before but it goes away and dosent do it constantly just every so often

08-09-2006, 06:55 PM

Applecare wasnt any help at all, they said tough luck basically.

08-09-2006, 07:20 PM

For the 'moo'ing issue, I'm not surprised they said tough luck. Mine has done it before, and the only reason I heard it was because it was at a time when ambient noise was zero. Even having the TV on was enough to make it hardly noticeable. Compared to the constant drone of most powerful laptops, it really isn't worth the level of complaints it's been getting.

Try closing all apps, and wait a few minutes for the system to start idling. My whine does become very audible when the cpu isn't being used.

It's only annoying when I need to keep it running overnight (downloading files). Then the whine cuts in and out every 30 seconds or so... (1-room apartment with combined office/bedroom, so it's annoying when you're trying to sleep. On the bright side we haven't had as many mosquitoes this year )
