MBP 2007 shuts down after 15 minutes??

[GavinBKK]

running 10.7.3, 3gb RAM, 2.33.

So, I came back from a biz trip and fire her up. About 15 minutes of use and bang. Straight off. Reboot and get to the Apple logo and spinning whatsit, then off again, but it tries to reboot itself. Then loops doing this. I halt this with a hard shutdown during reboot, using the power button. Left it a day, tried again and booted fine...... 15 mins and bang, everything is off in a split second.

Waited a few hours, tried again and fine, so checked the disk, how sever unlikely it is that that is the cause. SMART s fine. Do I need to dig a log out? Which one? If this was a car, I would say it was either the coil, or capacitor failing under heat/load. Clearly it is when the machine has warmed up that this is happening.

Can anyone point me in the right direction please? Prior to going away, all was well.

There are several apps and a few widgets available for revealing internal temperatures. Try one and see if one of your fans has frozen.

Couple of things. Is the machine running on battery? Is the power cord showing amber or green where it connects to the MacBook Pro? What do Console logs say at the time of shutdown?

[GavinBKK]

Installed IStat widget. Temps appear ok, but Memory slot A1 is 57 degs??

On mains at all times.

This run lasted 35 mins. the bang. Off. Log attached.

Thanks chaps.

After your latest two restarts, this entry eventually appears...

08/02/2012 11:54:01.000 kernel Previous Shutdown Cause: 5

12/02/2012 11:03:51.000 kernel Previous Shutdown Cause: 5

A casual google seems to indicate that may be normal (done from the  menu).


This is weird though...

^ it looks like logging stopped 4 days prior... and didn't resume until restarted. Was your Mac off during Feb. 9, 10 and 11?


Other than that, there are 93 occurrences of the string 'fail', but i don't see anything specifically "bad" prior to either shutdown. [probably hardware related, my guess]



Oh wait... here it is perhaps:

12/02/2012 11:08:08.000 kernel HFS: Very Low Disk: freeblks: 0, dangerlimit: 47

Your disk is full.
Show us...

df -h

... in Terminal.

This will sound odd, but see if the problem persists if you remove the battery entirely and run it on the power cord alone. It's not healthy for a laptop battery to run on the cord all the time (at minimum you should run on battery 4-6 hours a month), and if you have a damaged battery it could conceivably cause a power loss. If the problem goes away, buy a new battery.

[GavinBKK]

Tried to run memtest, but the machine shut off before completion.

Ideas anyone?

Amongst by computers I have a 2007 Macbook that exhibited similar behavior, though it also froze more and more often. The drive never showed a smart failure. One day before junking (and having bought a new Pro late 2010). I decided to use the new drive from the new computer in the old (since it was a little small for my needs).

*** The end result the drive swap turned the computer new again, all the problems went away. And note it I used a clone of my system so it was not as if it was "software/System issue" *****

We could go on about the importance of multiple back ups, but I have to run to work. PS. While it is good to run on batteries here and there, modern Lion batteries have pretty good management software. I suspect though its time for a new battery too, though not part of your issue unless your running on batteries when it happen.

Good Luck

[GavinBKK]

Well that was a new battery a few months ago. The System says it's 90% good and Coconut Battery says it's 78% good???

I'll go the df -h and revert. The system is showing me using 85Gb of 120Gb at this time.

More soon.

Well, that kernel message is unambiguous enough: zero free blocks.

12/02/2012 11:08:08.000 kernel HFS: Very Low Disk: freeblks: 0, dangerlimit: 47

And the word "danger" is not a common term in logs (as opposed to error and fail, which pop up all over the place).


Perhaps some program or runaway process is rapidly overfilling a temp folder somewhere (/tmp/ or /var/folders/*/*/-Tmp-/ or /.TemporaryItems/ or etc., etc.), and that forces the shutdown. Then on restart, all those temp items get cleared away... leaving no clues (save for that singular console message).

You need to monitor the situation in realtime.

[derekhed]

The Very Low Disk message from the kernel might be a red herring. I have the same message in my kernel.log four times in the past four weeks, every time after waking my rig, but not every time I wake my rig.

My boot volume is 58% full with 190 GB free.

It's an odd message though...

[tw]

well, just as a note, if you decide it's a drive problem, check the cable and reseat the connector before you buy a new drive. bad drives are usually obvious (making odd clicks and buzzes from internal mechanical failures, or showing bizarre results in the Finder or disk utility); a loose connector or bad cable can make the disk randomly disappear from the system's view, which might explain the 'zero free blocks' message.

[GavinBKK]

Ok, up and running with a TTP eDrive from external on the MBP. Volume rebuild, file optimization and permissions, followed by a (yeah, yeah) defrag. Let's see if this helps...

[GavinBKK]

Well, I have had TTP running defrag all night and it hs done some sixty thousand out of twenty nine million blocks.

35Gb free space. Seems to be adding up to a dodgy drive, yes?

I actually went ahead and ordered one from OWC Anyway last night, but that will be a while in the post. Age-wise, I can't complain really at five years old.

[anthlover]

I'm rather fond of the Segate Hybrid drives.... **Either way hopefully you will get a good working drive, I have occasionally gotten new drives that are flaky too (it happens to all brands).

I have to say I disagree partially about Smart (much less experience then the some here).

*But I have seen drives that pass smart and are whisper quiet and do not work properly anymore when old or even some that are new.

*I have also seen the opposite drives that fail smart, but seem to work fine.

I always replace in either case rather then tempt fate. Backed up or not I rather shell out around $100 bucks then risk data loss or be aggravated... Though at the moment with drive shortages prices are higher then they used to be.

I love OWC/Mac Sales too. Though for bare drives I often go with Amazon or Newegg.

[GavinBKK]

Well quite. That was my thinking last night. How much time do I spend buggering about with this drive when it is at/past expected lifespan, when $100 gets me a new drive and a decent night's sleep.

TBH, maybe overkill, but I bought new RAM and Super(!)Drive as well on a just in case basis. Bearing in mind my relative isolation, it is worth me getting the parts in and maybe squeezing a couple more years out of the old girl. Total $260 spend vs new machine? Easy choice.
