I've been to busy to post this up before now, but I figure it's time I did.

My beloved MacBook decided that at the Apple Tech Talks, would start turning off randomly. I had see this before, but it wasn't until then that I took notice. (Before then, I had just sworn that I'd left it running.) Rather embarrassing and annoying to say the least. Fortunately it was repeatable, make it work hard and off it went. Even better, when I took it to the shop, it wouldn't even turn on. Chimed and then turned off. Then it wouldn't even chime!

So, back to Apple it goes to get repaired. Hopefully it is a motherboard replacement, they can replace those damn early RAM latches that are broken as well. I actually got told that the very first Macbooks had a different design that didn't work and were quickly and quiety replaced. Was told to send it back for repairs under warranty.

This is my first problem with an early model Mac. Pitty, my iMac is a year old and hasn't skipped a beat since I bought it in January last year.

Poor little MacBook. Anyone else had this problem?

Ditto with the iMac. Wish i had a MacBook

Not personally, but I've read enough in industry rags about the MBs and MBPs not being up to par with Apple's usual quality that even if I could get one right now, I'd hold off. Glad to hear it's being sorted under warranty, though!

Yep.  "Never buy rev A" still holds true...

Hope it's returned to you better than ever!

Well my iMac has been going strong, but I guess there isn't much to go wrong and the case was pretty well tested.

I want my MacBook back!

That's because you've had your main logic board replaced.

I still find that kinda odd. When OS X installs, does it hardwire the serial numbers or something?

I had to send my macbook in to get the battery replaced (way to go compusa ). So look forward to that.

Man, I would love that. Still, I have no explanation as to why it will now just power off. Been happening since the MB replacement. First I thought I was going crazy, now I caught it doing it today.

Basically it appears to be letting the battery drain till there is nothing left and just turns off, not even being able to sustain sleep mode. Any suggestions of what I should do when I take it in this time? (Other than go in wearing jeans and a black turtleneck.)

Mine did the same thing but Apple determined that it was a defective battery, hopefully the logic board is still good.

Great so I had a motherboard and a battery fail in the same few weeks. Sweet, new battery!



So basically, replacement MBs don't have a serial number. The case owns the computer's serial number and the motherboard initially gets the same serial.

You don't need to send your whole computer in. If you call Applecare they will send you a new battery and then you will just have to send the old one back after the new one is received. I am on my 3rd battery in my MBP because of the same problem you are experiencing. Both times I had my new battery in 2 days. When you call they will ask if you have calibrated the battery, which is impossible when it randomly shuts down so just explain that you can't, and they will ask if you have reset the PRAM, so be sure to do that before you call.

There are lots of posts on Apple's MBP discussion board about this problem.

Have you tried resetting the SMU?

That is such a bunch of BS. Almost every Mac I've ever owned has been a revision A. People who say this act like later revisions never go in for repair. No one has ever shown any statistics that revision A models are more prone to problems.

Same here. then again, the only Mac I got was a Rev A (iMac Core Duo).
Has there been any issues with that one?
Oh, yeah. The iMac CD was a iMac G5 (iSight) with a CD chip in it (and minor HW changes).

My rev A Albook was great. Still works to this day (the power brick had to be replaced 3 times though).
