As I reported earlier, I had a severe problem with Time Machine on my MacBook Pro. As I experimented with it, I realized it was probably related to another problem I have been living with ever since I got the machine.

The previous problem occurred when I was running a build or other long, CPU-intensive operation. Sometimes, the machine would just reboot suddenly. And it was always when I was away. I had no luck with any of the usual fixes suggested by Apple or found on the web. I had figured out that it was probably related to the screen saver coming on, but it was impossible to reproduce this for anyone.

But something about Time Machine allowed me to reproduce this more repeatably: lots of CPU, generating lots of heat, coupled with intense graphics == reboot.

The folks at the FlatIrons Apple Store were really great, especially given the madhouse produced by the holidays. I described both problems and they just decided to replace the logic board. They ordered the part, and I was without my machine for only a day-and-a-half. It seems like this has done the trick. Hurray!
