This also happened to me after doing the OS X update.. Drives me crazy as it just shuts off unless my laptop is plugged into AC! ... the battery always shows a full charge! ... This never happened while running 10.4.6. I have a very early MacBook Pro CoreDuo 2 GHz system.

This sounds like a different problem. I believe most of the people with random shut offs do not see a difference whether on battery or AC. I think you have a bad battery.

Me too. Idle and working, until now only while running on battery.
I'll call Apple later today. I'll let you know.

Got my macbook back today and so far it seems to be fine.

It says on the letter that accompanied it that it has been fitted with among other things a new top case (as in the one around the keyboard). my macbook did not suffer from any staining but could they have replaced it to ensure i don't get it in the future? because the texture feels slightly different.

Incase anyone is interested it says it was also fitted with a new bezel and a new thermal module.

It might be a bulging battery.

Take out the battery and look at it from all sides.

From any views do you see the edges bulging out from the case?

That would be it.

My MBP had a bulging battery and it would shut off at around 80% and the battery had lost 60% of its capacity according to Coconut Battery. I took it in to the Apple Store and they sent me a replacement battery (though they couldn't just give me one from the display models of course :rolleyes: )

The problems most of us are suffering from happen when the computer is on AC power or not, so it cant be the battery. I've taken mine back, and they are replacing the logic board. The battery was one of the first things that i though of, though.

EDIT: I got it back the other day, and so far i haven't had a problem (touch wood).

So many problems with this new Macbook.. I kind of regret getting one..

I had my first random shutdown last saturday morning. It did it again later that day and nothing since this morning.

This morning I had to "start" my computer 5 times. 4 times in last 1.5 hours.

I don't think its a heating issue as I would start it, close the top, open it back up 15 mins later, and it would do it again. I think it could be something to do with sleeping and waking back up.

Either case, i'm sending my Macbook for the Pro. But it seems like it happens to both regular and pro macbooks.

Is the quality of Mac laptops going down?? I had very little problems with my previous powerbooks (7 or so powerbooks in past 10+ years).

They have had some major issues with these Intel laptops. I don't think it is an downward trend, just a bad year with the new technology. The processor noise is a Yonah issue on battery, the heat is growing pains (meaning Apple needs to learn to make Intel tech work for them), and the logic board problems are probably also growing pains with Intel inside. There was a bad run of batteries and screen power converters for the MBPro, I'd still say those have more issues than the MB.

I had mentioned earlier that our 3rd logic board was still having shutoffs, but after grilling my wife again, I guess that was only once. It could very well have been a one-time glitch or even user error. So, hopefully ours is fixed.

I have had exactly zero issues with my Intel Mini. It is a fully maxed out version.

i just started experiencing this problem too. mine is also wk 19. on the phone with the apple dude today, he gave me the impression that they don't know exactly why this is happening when i asked him whether they are getting many complaints (as we all know we can all belong to some mb random shutdown society now).

he said defo call back if it does not work (resetting the pram and the other thing+ disk utility) so i am wondering if they actually have no idea why? or else they would just say, oh yeh, i know. do this, it is this problem? no?
or are there degrees of severity of the problem?

or am i being incredibly naive about it?

btw mine is time related it seems (for the last couple of days) to be allergic to 11:07/8 am. anyone else have that?

I just started getting the random shutdowns last weekend. I've had my macbook since 6/8/06.

It's happened on three occasions. When it happens, though, it happens about 4-5 times in a row before it settles back into it's groove.

The first time, I was running Diablo II.

I can't remember what I was doing the second time.

The third time I was running Handbrake and FTPing a file.

There is nothing common between my experiences. I was on A/C once - on battery another. I had external drives plugged in once - nothing plugged in on the others.

It may be a coincidence, but they've all happened after I upgraded to 10.4.7...

I am going to the Apple store this weekend to report the problem to a genius, but I don't have high hopes that I will be able to replicate the problem for them. Nevertheless, I'll report back with what they say.

If they want to replace parts on my computer, I can't give it to them right away (I need it for an upcoming trip) - but I will give it to them for parts replacement after the Labor Day weekend, if that's what they want.

I'll keep you guys updated.

ughhhhhhhhhhhhhh, I need a 100% working laptop. It's kinda sorry seeing my $1500 spent on a product that 'might' work. If a car company had a vehicle that would randomly just turn off that would be a big issue. Surely this hasn't been a large issue (I'd approximate under 100 I've seen on the net with this issue) but even if we are in the minority I think we're entitled to working computers. Not a "Oops! I'm sorry, it looks like your $1500 didn't win you a working laptop! Try again next time!"

I'm just frustrated. 1hour until I'm off of work. Then it's off to call Applecare a 2nd time and tell him the reset the PRAM didn't work and if HE looked at the Apple Discussions he'd see that others have this problem.

Didn't Apple have a policy at one point in which three major repairs warranted a new machine or refund? I would think three logic boards would grant a consumer the rights to their money back.

I think that's a California State policy. And some other odd state does it too... I think New Jersey. Though I'm sure lots of people have gotten new machines after 3 just because Apple wants to keep them as customers.

They are replacing these during other repairs since the old bezels were known to stain. I recently had our logic board replaced and they replaced the bezels too, I asked them about it and she said it was because of staining complaints - although, ours was fine...

I'm getting a box today (or monday, depending on the speed of the Post).

So hopefully they can fix my problem. Interestingly enough the Problem description on my Request says:
Problem Description: Power - Power Adapter: Dead / no power
I'm going to include a note saying it loses power at random and I've been unsuccessful at reproducing this problem. Because they'll turn it on and be like "hey, it powers on!" and then send it back unfixed. Sigh...

UPDATE:

After 4-5 random shut down yesterday, So far today's been fine. I'm backing up all my files and sending this one in on monday. I'm upgrading to Macbook Pro.. but seems like some of the pro owners are having this issue also. All I could say is, if I start to have this issue with the pro, I'm going to go nuts!

I also think its the new update that I install on to this macbook. I hope Apple fixes whatever they did. Because all this started after the new update.

Well, some hopeful news. On the Apple Discussion Forums user pmuellr is suggesting that the Macbooks are having a fault with the thermistor cables. Apparently they could be sensing wrong temperatures and "thinking" the Macbook is overheating when it isn't really over heating. In the thread link there is at least one other user whose gotten his Macbook back without a new logicboard - but new thermistor cables.

Dropped my macbook off at the Genius Bar on Saturday - they said they were going to replace the Logic Board and had one in stock and should get to in that day.

But it's now Monday morning and I've not heard anything. I'll call them this afternoon and see what's up.

Hey all,

This is not exactly a random shutdown issue, but it seems at least related. I'm a relative Mac newbie, and have a PowerPC iMac G5 and a brand new Intel MacBook (2Ghz). I've noted, on BOTH computers, cases where the computer appears to go to sleep right in the middle of working on something. The screen goes dark, and then a few seconds later (since I have the password to wake up option enabled) the password screen comes up. It's odd because it's not as though the computer is sitting idle and the screen saver starts due to inactivity. I am actually actively working on the machine! The computers do not shut down, and no data is lost, but it is very annoying. Happens maybe once a week.

Anyone else see this or have any ideas?

update: did it again last night whiles i was loading jedi knights (yes i decideded that in order not to tax thhe thing so much i will stick to the oldies). now everything i type has at least a five seconds lag and i couldn'teject disk last night. even the trckpad/ restrt trick was a bit too trying for the computer. got an appontiment at the genius bar at 8:40pm. its the last slot so hopefully they won't be running so far behind as to bump me off to tomorrow.


arr this is too annoying. the sentance is still at the 'icioundlt' part now.

hences sorry for all the sps. its just too difficult to see or correhut down bus won't be able to recreate itself at the shopp.
arrrr.

may be i will get special consideration since this is a week 19 model and some of you said they have faulty logic boards?

plesase please oplase.

Well, everyone who has had logic boards replaced seem to have the problem return within a week. That right there is not indicative of a logicboard problem. Most people believe it's a problem with the heat assembly.

I'm still waiting on my shipping box from my Applecare call last Thursday...

groan...

post genius update: the guy decided that its bad ram after opening up and seeing that it has kingmax ram in it (note: i;ve also realised i've been conned by my reseller! i've ordered a bto and they gave me stock with two generic sticks... granted that will all that ram it still cost less than the 2gz white model here...). he then said...' the last 3 mb i saw that had your problem had ram problem, therefore since you are not using apple ram, this must be your problem, announced that its going to cost me 480 quid to rebuy 2gig of apple ram and said... of course you can try 3rd party again, but why won't you.

so guys, is kingmax ram that bad? the reseller i got the computer from also ran off with my apple stock (my mom got it from me in hk where everything is cheap) so i can't even bung them in to see.

then the guy told me off for playing jedi knights the whole weekend because that exhausts the system. Hello! its like a 3 year- old game...

so what next dudes?

mine did that, but i took it apart and relayed all the cables, open up the console and click on logs and then system.log, then search for "shut" copy and paste what comes out.

Just returned from the Genius Bar with my Macbook (with its new Logic Board).

Working on it feels like working on a time bomb. Will post here if it starts exhibiting problems once more.

Okay, there’s a lot of misinformation going on. There is no such thing as “Apple RAM” Apple used Samsung at one point, but I don’t know what it is currently. Kingston is cheaper, but it isn’t horrible. Some machines take RAM differently, so Kingston may be fine on one and not the other. Make sure the reseller didn’t note the RAM specs in a receipt. The Genius is definitely going to want you to get Apple's overpriced selections. Technically all the RAM is third party, Apple just chooses one and decides it as the official part.

Where’s CanadaRAM when ya need him?

I just read KingMax not Kingston, sorry. I know nothing of KingMax. Anyway, as stated may times in this thread, it is not your RAM. Apple has an unknown problem on their hands. It could be bugs in the Core Duo/logic board, battery, heat sensors, OS X, etc.

just in case anyone is interested in my "sawdust" bits of ram (yes still bitter about that) here is the website http://www.kingmax.com/semiconductor/index.htm

website design isn't very good, but they seem to think they are amazing. and by default since i am chinese i should support 'my people' right? (yes, lots of logic going on here)

no shut down yet today, so that makes it 24 hours where the computer has not skitzed at me and its been on for 10 of that! woo (fingers cross)

and btw, i've come acrossed another theory(ies) on the apple discussion website that it might be the:
a)lollipop? huh.
b)sudden motion sensor
c)hard drive
d) anything else up to and including the computer case.
e)core2temp- deleted that when this started...


right...
