Q: Previous Shutdown Cause -86

I have a Macbook with random shutdown problems. The System logs do not give any indication of any event occuring prior to the shutdown.

It is a 1.83 GHz Intel Core Duo MacBook, and a Feb 2007 model. Its worth noting that I have configured this machine to shutdown at 4.30am and restart at 4.45am which it always does, unless the random shut down occurs first, then it will never start up.

I cant get access to this macbook easily, it is housed within a console, and is 8 hours travel to get to it, so the logistics of any troubleshooting are complicated.

Where is the list of these Shutdown causes? knowing what 86 means is going to be extremely helpful.

1.83 GHz Intel Core Duo MacBook, Mac OS X (10.4.11)

    Its hard to understand why a code like this -86 is not documented anywhere.

    I transported this macbook back to the office, it was overheating, cpu getting to 80+ degrees But still i would expect that a computer shutdown due to overheating would be logging much clearer events.
