I'm mass converting apple lossless files to mp3 to reduce the size of the files to load onto my ipod. I'm doing batches of a couple of hundred songs and the my laptop just shuts down in the middle of the process, no error message, just shuts down. It's happened at least a dozen times, basically every time I run it. It does look like the batch processor is maxing out the CPU, but not sure why that would cause the shutdown. Any ideas on what to try?
