Hi.

My MacBook Pro just randomly restarted on its own. The screen went black as if it was about to go asleep. But, after a few seconds, it just restarted. The mains power was plugged in (and the battery was fully charged), so it definitely wasn't going to sleep.

This has never happened before. Any ideas?

Are there any logs that I can check that would indicate anything?

Thanks,

What model MBP is this?

/private/var/log/system.log
/Library/Logs/Console/UID/console.log

where UID is your user ID. If you're using the first admin account ion your iMac that'll likely be 501.

Thanks, Simon!

The console log didn't seem to show anything. I checked the system log, and between 13:07:14 and 13:38:07 nothing was printed to the log, of which 13:38:07 being the point of the restart, since the log then starts to list the boot process. Nothing prior to 13:07:14 lists anything that I can see is of any concern.

I've just checked the S.M.A.R.T status of the drive using Onyx, and it seems the volume needs repairing. I guess it was the drive volume.

It seems a bit odd, though! What would cause the drive volume to need repairing?

Thanks,

I had this problem with my MBP, and I traced it down to a bad RAM stick. Received new RAM under warranty, and I've never had the problem again. It would happen to me once per week or so.

Hope that helps.
