Mac Pro shutting down itself after 2-3 days of inactivity

[yomibro]

For the past 2-3 weeks I noticed that if my MacPro is in sleep mode and it's not used for two to three days the system shuts-off by itself. I just came back from work today and noticed that the system is off, the last time I used it was this past Sunday.

Is there any logs that I can check to see why it shutdown or recommendations on what to check for?

Why would you leave it in sleep mode for 2 or 3 days? It's probably just fed up and decided to take a break. lol

I'd open up the Console to check all messages.

You might be able to use the "last" command in Terminal to see the shutdown time of your last login.

Check "schedule" under power options to see if the MP is set to shut down after a period of time. Other than that maybe a power issue? Do you have it on a battery backup system?

I show a crash on 3/4, other then that nothing until today's date when I turned it on after I came back from work.

Since you know the time(s) of the crash(es) try to see what shows up under All Messages in Console.app.
