    Its not a software update problem. Mine is doing the same thing and I have not touched the software. As well, I have done all the RAM removal, tests etc that have been suggested here.

    Additionally, there are no messages in the system log.

    There is clearly SERIOUS issues with the early runs of the MacBook.

    I hope Apple steps up to the plate and offers a recall/replacement order for these.

    Tonight I finally have an appt at the genius bar to look into this.

    I am not looking forward to the experience, to be honest.

    That's exactly what has been happening to me. It sometimes takes pressing the power button 4 or 5 times to start it up. But I'm still on OS 10.4.6. . . so I doubt that's it. . .

    I wonder when Apple will officially recognize the MacLemon problem on their hands?

    When there actually is a MacLemon, that's when.

    My does it too - seems to only do it when on battery power, but is VERY difficult about starting up - this has got to be a recognized issue!!! To many people with brand new computers that simply don't work!!! (mine is week 26)

    Mine is doing it when Plugged in. I dont use my macbook really at all unless I'm plugged in. I honestly don't think it's a battery issue, but who knows, I could be wrong.

    Just called the apple store. I think I'm going to call on wednesday and setup an appointment. It's been doing the power off thing just about all day. I got so angry I called the apple store, and he said that my macbook could be a lemon and he's seen two others that had the same or similar symtoms.

    This is frustrating. I popped open the back and check how the RAM was seated, and I made sure to give it an extra firm (but loving) push in to make sure it was seated. I also tried the taking the battery out, unplugging it and pressing the power button for 5 seconds. However, I'm still having random power offs. It really ***** when I'm typing email and it does this, heh heh.

    you're all quite lucky...mine won't stay on for more than about twenty seconds, and it's not even three weeks old! I'm so incredibly peeved about this...I too have tried all of the recommended fixes, and nothing works. Right now I have a dvd in there, that I can't get the computer on long enough to even eject...

    I have exactly the same porblem starting from this morning. It typically happens when the computer wakes up after several hours of sleep. I doubt if its the internal heat, as my computer is not hot at all when this happens. Also, there is no random power off so far if I use the battery. On my macbook, I only see the problem when I use the adapter.

    It's so frustrating. Mine is only one month old. I hope Apple will initiate a recall.

    This happens to me too. I've noticed that the longer my computer is shutdown the longer it will run before it shuts down again. Once it shuts down i generally have to leave it off for a couple of hours before i can use it again or esle it will shut down imediatly after i access the OS.
    Does doing a hard ram reset harm the computer in any way. Since this problem started happening i started having another issue where upon booting my screen starts displaying colourful vertical lines that keep increasing in number. i have to do a hard ram reset to get it to boot into osx. I'm currently out of the country but apple told me they would replace my MB once i got back in August. Should i trust them?

    I too had this problem about a month ago. I went through applecare, sent it off for repair, waited 2 weeks in frustration while they diagnosed the problem, and finally convinced them to send me a new one. The culprit: bad logic board. They sent me a new black macbook (original was white) and it has been working well for about 4 days now. Fingers are crossed. Just out of curiosity, what widgets are you guys
    using? I noticed that my problems occured around the time I installed the iStat widget, although I didn't realize at the time. But I think some widgets may be the cause of some of these issues, just a hunch but you may want to try switch off certain widgets that run in the background as they may interfere with the computers normal operation. Who knows?

    I also think it's more of a physical defect of some sort... It crashed on me when I had booted from the OS X install disc (I didn't actually try to re-install because that seems risky - what if it crashes during install, then I won't be able to boot up at all. I was just repairing permissions.)

    The problem seems to be getting worse. It turns off more often when it's not running on battery - which could mean that some component is having heat problems. I guess it could point to a motherboard defect. The RAM passed the extended hardware test twice.

    I really don't want to send it in for repair, it's gonna take like a month (vacation period) and I need it!

    sorry for my bad english speaking.
    Mine shut down randomly too. And i can see in system.log an error : "Previous Shutdown Cause : -82"
    It s not a system problem cause i tried a clean install, and the memory are new too.
    I already try to reset PMU without success, and i am trying without the Battery now... i ll inform you if it resolves the problem.
  • cbnaut Level 1 Level 1 (0 points)
    Is it iStat to blame? I have this wiget too. I'll see what happens if I uninstall it. Mine is a 2.0 Ghz black macbook.
  • gram Level 1 Level 1 (0 points)
    I doubt iStat is to blame - I don't have it installed at least.. What I have noticed, after reading some other post here on the forum, that my fan does not seem to really go on when the computer is working intensely. I have been lucky (or what the term is) enough to get a loud fan, so I can tell if they are on full-speed... The fan seems to still be running to some degree, at least it starts mooing a little, so it's not completely off.

    When watching coreduotemp and running for example yes > /dev/null, I can see that just before it will shut down, the core speed drops to 1.0 GHz (as it should if it's overheating). If I quit the program immediately, temperature will slowly drop again, and at some point speed will again be 1.5 GHz (which is normal when it's not doing hard work). If I don't quit, then 4-5 seconds later - forced shutdown. It really does seem to be the CPU overheating in my case... It also makes sense that it takes a while to be able to power on the macbook in this case.
