macbook turning itself off - Page 2

Mine has been in since the 24th of July. Apple called yesterday and told me to go to my local Apple store and pick up a replacement.

I'm sure the same thing will happen to me. I bet this is a logic board problem they are trying to keep quiet.

They've had mine since Aug. 1st.

..........

woa, about 2 weeks ago i was determined on getting a new macbook for university. Getting second thoughts now but i was gunna wait until september to see if any updates were announced anyway. The only apple products i've had so far are ipods, my first 40GB 4th gen ipod, that stopped working 1st in warranty and then 2nd out of warrenty. My girlfriend then got me a nano, which has stopped working. I thought that their laptops would surely be of better quality? Not really sure what to do now, don't want another PC, but dont want a big white piece of plastic that just DOESNT work.

I’m unhappy with my macbook experience but I think your hesitation is unwarranted.

Every car maker you can name has had million unit recalls at some point in the past (ford, Toyota, GM, Honda, Mercedes) for one problem or another. Would you never buy a car from any such carmaker again? Of course, not.. that would be stupid.

Hundreds of thousands of macbooks have shipped; perhaps a few hundred are experiencing the problem we have identified here. Nothing in life is 100% all the time. This is my 6th Apple computer and I wouldn’t hesitate to buy another.

I think a one year warranty on consumer electronics is reasonable... especially if you buy them with a credit card that extends that warranty by one additional year.

My three-week old MacBook began randomly shutting down yesterday. I had no problems previous to installing the new firmware update that was released not too long ago.

As mentioned in this thread, the computer shuts down with absolutely no warning. This is my second Mac (my Powerbook has not crashed once in almost two years). OS X is rock solid, but this is obviously a problem that negates this (haven't lost any data yet). What to do?

Here is the console system log:

BTW, someone mentioned that there is a $150 fee to back up your data. I believe the fee is $50, not $150.

Aug 29 15:18:29 localhost kernel[0]: Previous Shutdown Cause: -72

Well here's my .02 cents

Apple is obviously not fixing the problem because I've gone through 2 random shutdown macbooks already. I am typing on the 3rd one and the random shutdowns started on me again. I've only had this macbook for 3 weeks.

I didnt have any problems before I installed 10.4.7

When I send this one in and receive my fourth machine, I'm not installing the 10.4.7 update. I'll just wait for 10.4.8.

Apple is already releasing prelimanary builds to developers, so i'm sure it will be out in a couple months.

Good luck to everyone.

Call apple. Get a brand new machine. Dont settle for a repair.

I'm thinking of asking for a new one, but I'll see what they tell me. This is bar none the best laptop I've ever owned (much better than my previous Powerbook), it is a shame that this has to ruin what would be otherwise a great experience.

What the hell is Reason for Shutdown -72? Where can I find out what this means?

People with the sudden shutdown problem may be interested in this.

My MacBook has officially joined the random shut down club.

When did you buy it? I thought they had fixed / were fixing the problem and I was about to get the wife one (well, I would be the main user but she would be happy to have received it).

The RSS problems have been narrowed to a serial number range. I don't think the ones being produced now have this problem. I rembember reading the serial range somewhere, but I can't find it now (mine was within it).

I just took mine in. They said that they know what the problem is and that I should get it back in 7 days.

Cool. Guess I can go and buy myself...er, the wife... one.

I can't find the article. My MacBook's serial number began with 4H. I doubt they're still making MacBooks in this serial range, but ask to look at the box just in case.

I sent mine in for repair. It took almost three weeks and reversing the charge on my credit card (that got their attention!). They fixed it and I’ve had no problems since (before the firmware update).

I didn't feel like I needed it, but I did update the firmware once it became available. Again, no more problems.

That's not acceptable. Keep on phoning until you get someone who agrees to get it repaired. The first MacBook I was sent had its display bezel coming away from the display (problem appeared straight out of the box) and they replaced the whole machine no questions asked.

http://www.apple.com/support/downloa...eupdate11.html i know there is a forum thread thing on this BUT when i was googling to see why my macbook kept turning off this came up really high up so if anyone else comes here they can just follow that link...

Sorry for bumping up an old thread, but I'm now in this club.


I just tried this. In addition I've tried resetting the PMU, as someone stated earlier in this thread.

I have also installed the SMCFanControl, but no luck... though its nice. Yes, I have the SMC Firmware update from apple.

The thing is, is that my Macbook does not randomly shut down when I'm using the AC adapter. Only when I'm using just the battery is when I run into these random shut downs.

I'll see if resetting the PMU or whatever works for me. If not, then I'll be back.

FYI: my link above no longer links to what it did when originally posted.

My Macbook also randomly shuts down sometimes, when the battery is very low - instead of going to sleep the machine shuts off completely. Is it the same for you? I think that's a slightly different problem from the original one - in that case the machines were shutting off without warning at any moment.

The site that you linked helped, though. So thanks for that and your reply. My Macbook has the issue where it shuts down without warning. I tested it today, fully charged battery and my Mac shut off when it hit 85% charge mark. Then it didn't happen again and I was able to go all the way down to the 12% mark on only the battery.

But here's a question for you or anyone that went through these random shutdowns: Did any of these random shutdowns happen when you were only using the AC adapter? Or did they only happen when you were only using the battery?

Again, for me, these random shutdowns are only happening when I'm just relying on the battery - which makes me think it could be a battery issue.

i had my MacBook Pro behave similarly although not persistently. apple getting as bad as Microsoft with all the firmware upgrades, at least overall performance doesn't decline as it usually does with Windows systems requiring a reinstall every now and again.
