Thanks, we are aware. The poster posted here too. I don't agree with his claim, though he may be right about inherent bugs in CoreDuo. All processors have design flaws. If the CoreDuo itself were the cause of these random shutoffs, we would be seeing more consistent, testable and repeatable results, not to mention more widespread and even moreso in the PC community (There are tens (hundreds?) of thousands more Dell units out there than Apple). Plus we would see this in MB Pro and other Apple Intel units.
My week 21 had problems from day 8. Its replacement, a week 24 , has performed flawlessly, though I will feel more confident after one month of ownership has gone by.
Many, including myself, have had shutoffs cold and hot and have monitored cpu temp's and do not concur with the poster's findings. Plus he speculates on the -82 and -72 shutdown cause codes. There is no documentation to back up that claim. Just more speculation.
I still stand by the faulty logic board theories posted by others. Those of us who no longer have the shutoff issue have had their logic boards replaced, either a repair or a replaced machine. We have also ruled out ram, os installation, software, plists, hard drives, PMU resets, battery vs. adapter, and PRAM.
