    Pertaining to the system.log's "Previous Shutdown Cause:" entries.

    In short, my MBP has a cause of "0" most of the time. In my previous careers in programming and systems work, I'm assuming that's similar to an exit code and should be "good."

    However, occasionally I get a cause of "-72." This is accompanied by random shutdowns, usually 0.5 to 3 seconds after boot (during the gray power up screen).

    I've tried searching for a listing of codes on this site, Apple's community forum, and on Google to no avail. I'm curious to know what the "-72" signifies.

    (Yes, I do have AppleCare, and in fact just got it back from Apple less than a month ago for an unrelated issue. I'd just like to have as much information as possible before calling them again).

    -72 refers to a problem with the heatsink.

    -72 refers to a problem with the heatsink.

    Try reapplying the thermal material if that doesn't fix it I'd check the cable or the heatsink itself.

    Not only cryptic, but archaic. It's a list of pre-OSX codes last revised in 1998.
