I have a week 28 macbook and started getting random shutdowns last week. I found holding the start button solved the issue, but I learned that the speed dropped by doing that. I next did that until the unit was warm then rebooted and have had no problems. I called Apple on this and their only suggestion was to re-seat my RAM. I did and the computer wouldn't work at all. I got the colored lines on the screen and nothing worked. Finally did a PRAM and now we are up and running, I hope all things are a go, we'll see. I'm running 10.4.7 on a black macbook 2.0 GHz with 1.25 GB RAM
so i got my logic board repaired, and now when i use my laptop, it doesn't always turn on.
so i went to the store a third time, and the technician resetted the pram.
so i asked him how to reset the pram. and he said i shouldn't really do it unless ihave to cos it actually ruins some parts of the computer...............
so do i have to reset the pram everytime it doesn't start up????????????? until the computer is so damaged that it doesn't even work????????????
i sooo want a refund. but i start college in four days..
my 90 day warranty expires in mid september, so i'm screwed. unless my one year support covers all repair costs. does it?
i hate my defective macbook.
You have a 1 year parts and labor warranty.
You have a 90-day Free Phone support warranty. The difference is that, after 90 days, AppleCare may ask for a credit card to charge the call IF if turns out to be a software issue you are calling about. If not, they do not charge the card.
It is a pain, I know. My BlackBook went nearly 30 hours without dying after the latest SMC firmware update, then died twice in half an hour.
Who says that Apple knows what is going on? What evidence do you speak of?<</div>
Do you have evidence Apple doesn't know what's going on?
Perusing these boards, it seems obvious high heat is a factor in causing random shutdowns. My Macbook was returned - after two days - on August 2, w/ a new logic board and dramtically lowered running tempertures. The cooling system was further enhanced - on my MacBook - with the recent firmware update. I know have a laptop computer.
Admittedly, time will tell the tale, and even two days without my computer was extremely annoying. But it's obvious Apple at least thinks it knows what's going on and so far, in my case, whatever they are doing now is working.
Got my MacBook back last Friday,
so far the Mb is working fine.. only problem was that the HD was formatted and i have to install everything again
After I got it back, I also did the Firmware update ...
Some impressions ....
the temperature is still and the fan works more
BUT I got another MB and that one is still in Apple for repairs .. seems it didnt pass the last check ...

I'm guessing Apple Technicians are in over their heads with MacBook repairs right now, so I don't think I'll get it for a while.
Yep, that's a guess. Got mine back in two days, which was about three weeks ago. I would guess, now that the problem appears to have been heat related, that repairs are going to go much more smoothly - and will go quickly.
My week 19 Macbook started the random shutdowns about a week ago... and this past Saturday night, it shutdown and continued to shutdown after 3 power ons... I made an appt with Genius for Sunday.
The genius was not "stunned" when I said random shutdowns and seemed to indicate he had seen this before. He wrote a repair order that says "logic board" on it, but I am hoping they see the random shutdown on the ticket and know it's probably not the logic board and replace the "right" parts...
What a pain...

The genius put MLB on my repair order and they didn't replace the logic board. It was shipped out, repaired, and delivered to my house in less than 48 hours, and (knock on wood) has had no random shutdowns since I got it back a week and a half ago. So apparently what the genius puts on the ticket isn't necessarily what they go by.
Very similar situation here, however I updated my SMC firmware two days ago. I just installed Call of Duty 2 this morning. The shut down happened three times during the selection menu, loading process, and actually playing the game for about one minute. I first thought it was just the problem with this certain game. Then I restart my MacBook, and open Safari, it shuts down again.
I bought my MacBook (with serial no.4H6241, and upgraded memory to 1G when placing the order with Apple Store) about two months ago, and running with no problem at all till this morning.
I was just listening to the MacCast podcast and they mentioned that 3rd party ram does not have the heat spreaders on it that ram from Apple does and that this could cause over heating problems. I'll admit - I got 3rd party ram because I couldnt afford the laptop AND the ram from Apple. Now its too late, I'll be going into my local Apple store this weekend to send it in for random shutdown repair and contacting the company I got my ram from to return it (I'm not hopfull) and then I'll be saving my pennys for Apple ram and using my macbook that cost twice as much as a windows machine to run slower.
Live and learn. I still love Apple products! I just don't think I'm rich enough to afford them
Simple CPU useage doesn't seem to be the answer here
We are dealing with a power related problem maybe we should all be thinking about things that might stress the power systems? Do the people who have more frequent shutdowns do something different with respect to sleep, shutdowns, and restarts that somehow increases the probability of a random shutdown?
For example, I normally just put my computer to sleep when I am done with it. Maybe lots of restarts strsses the PMU in someway that leads to more random shutdowns?
