Will the console log show a history of random shutdowns?

Question

My macbook has suddenly started the random shutdown problem. It started a couple of days ago, I'd had no problems up until then. At one point today it was shutting down immediately on waking from sleep, and then would only stay on for about two minutes with the fans racing before, bang, off it would go. I left it alone in exasperation, then returned to try again, and this time it lasted around an hour before shutting down repeatedly again. I will need to take it home to the UK to my local Apple service centre and I am worried that if it doesn't actually shut down in front of them when they have it they will tell me there is no problem and won't repair it. I know that this macbook has the RSS issue now but it really is random, so can I prove it from the console log? I looked through this just now and of course most of it means nothing to me but I did notice that there was a line saying "cause of last shutdown -72" occuring many times since this started. Does anyone know what this refers to and will it show that the problem is definitely happening?

Answer 1

What does the holding the button down trick do?
From the Apple article I referenced in your earlier thread:
"If your MacBook is in a state where it will not remain on long enough to install the update, wait for the issue to reproduce itself. Once the MacBook has turned itself off, turn the computer on the by holding the power button down. Keep the button down until you hear a single long tone. Once you hear the tone you can release the button, install the recommended updates, and restart as you would expect."
Allegedly, this throttles the CPU to 1 GHz.
And I am slightly worried that a2dox says that the
problem returned even after the repair..!
Different experiences for different people, during the period when Apple had not yet figured out the problem. Their contract repair facility was doing different repairs, some getting heat sink replacements, some logic board replacements, some both, and, later, some a differently designed heat sink. When one of those repairs didn't fix the problem, they would do another.
