macbook turning itself off
my macbook keeps turning itself off. first of all it only did it once a day, now its more than 5.
i have noticed that it has only happed since i started running 10.4.7. i dont know if it coincidence, or if it is linked to the update. i have tried running it without the battery, and it still happens, so it cant be that.
do you guys have any ideas on what it could be. if it continues after the next firmwire update, then i will be taking it back and demanding a new one.
thanks

Looks to me like you've got a hardware fault. I don't think anything system related would cause an immediate shutdown unless there was a firmware update maybe or something affecting the tenperature control. One way to check is to reinstall OS X from your system disc. I would do that before taking it for repair.
To reset the PMU on a MacBook:
MacBook, MacBook Pro
If the computer is on, turn it off.
Disconnect the AC Adapter and remove the computer's battery.
Press and hold down the power button for 5 seconds and then release the button.
Reconnect the battery and AC Adapter.
Press the Power button to restart the computer.
thanks for all the pointers
ill let you know how it all goes
cheers
The only culprit I could imagine was bad memory (I upgraded to 2gig two days after I got it), but that was weeks ago and there is no pattern to the shut downs that one could attribute to memory use. Long ago I had a memory chip that went bad on my desktop (after years of use) but the problem only occurred when I launched one too many applications and effectively called on the available memory (chip).
There is no such discernable pattern with the Macbook. It shuts off on its own with or without applications open and sometimes even shuts down when it is in the middle of restarting from a prior shutdown. Basically, I never know when or if it will stay on or for how long.
Also, I can no longer open activity monitor; the application refuses to launch.
How widespread is this problem? Can this be fixed with a firmware update? I'll try the suggestions above.
Long story short, don't throw laptops. Period. Also, check the temperature of the processor and make sure it isn't getting too hot. Those chips are set to bail before they get too hot (and in reality, it is usually after they get too hot, as I found out).
after i re-installed 10.4.7 and reset the pmu it has only turned itself off 3 times,
this is better, but it still shudnt happen

In the discussions on the Apple support site there are several people including myself with this problem. They are being told it's the logic board. I have always had Pro series notebooks until now but remember my wife's logic board problems with her G3 iBook and I am very upset. This sucks. I have lost a ton of work this week. Oh, and I went back to 10.4.6 because from what I have seen 10.4.7 bites.
I hope it's not a logic board thing again. I had a logic board failure on an ibook G3 too and shortly afterwards I got rid of it. I got it replaced under Apple's extended repair program because it was in a bad batch but I'd heard that some people's logic boards had to be replaced multiple times and I wasn't having it.
Either way as you said, it shouldn't be happening. TAKE IT BACK
to tell the truth i dont realy get the heat issue, as it normally operates at about 60-70 degrees C, like it always has
I tried twice to restart and it shut itself off again within two seconds. I waited a minute and the third time it started up. This is really annoying. I?m traveling right now and can?t do without my computer, but when I get back home I?m going to call it in and probably take it back to an apple store. This is probably the 7th or 8th time this Macbook as shut itself off.
This is my 6th Apple computer and my 5th Mac. Obviously, I am a loyal customer, but this is wholly unacceptable!
You should if you haven't.
Good luck!
as i have found a few ways to over come it slightly
such as:
hold the power button longer after it shuts itself off
reset the pmu every so often

Logic boards behave oddly when they are broken or in the process of breaking. There's not really a cure. When my logic board was going, I had the notion that by plugging my laptop into an external display it fixed the issue because it seemed to work for a few hours. Then it broke again and I'd find another cure. Eventually, it just stopped working such that nothing made any difference.
The solution is to get it replaced under warranty and for Apple to stop using such crappy boards. I don't really hear of other laptop manufacturers having logic board failures much, even Dell, and I presume they are using cheaper components.
Dude, why are you still talking about this and trying little solutions for "making it happen less often". This should not be happening, period! Take it back. They will give you a new one/replace whatever is screwy. You have to still be in warranty.
alrite calm down!!
but seriously, it does happen less often now
