Bumped Mac Pro tower with chair leg and it rebooted

[Bontchimuz]

I was at my desk last night and moved my chair and accidently hit the Mac Pro tower. It immediatly shut down and rebooted.

Is this a safety precaution that Apple has put in place?

I have hit it before with my desk chair by mistake and it did not reboot.

I found it very odd.

Thanks for any insight.

Open up the console and check the system log. It should tell you why it rebooted. And if no reason is given you probably bumped the power.

All Mac Pros are fitted with gyroscopes and motion detectors.
On being bumped, OS X solves a matrix of partial differential
equations, applies the results to a stress deformation model
and calculates the likelihood of iTunes skipping. If the
probability is greater than 1/(1 - e) the machine will reboot.

Or maybe the power cable is loose.

It's confusing.

How does one does this exactly?

Thanks,

That's pretty funny, cos the same thing happened to me a few days ago!

I bumped the outer right side (side opposite from the power button), and the screen went dark. At first I thought I might've knocked the video cable slightly loose, but then I heard the chime when it boots up.

Really weird, but unless it starts doing that regularly, I'm not gonna worry about it (and I have full Applecare just in case anyway )

Thats exactly the side and what happened to me.

Run /Applications/Utilities/Console.app

Hit "Show Log List" to see the list of available logs if it's not showing.
Look for clues as to what might have happened in system.log or under Console Messages.
