Computer shuts down after a minute of inactivity

After just over one minute of inactivity (no moving mouse, typing, etc.), I get a "Logout, Cancel, Restart, Shutdown" screen. If I don't quickly click out of it, the computer totally shuts down. I have an Intel Macbook. I don't believe it's a hardware problem; I've run the hardware test and it comes up clear. Any advice or help would be greatly appreciated!

Thanks :)
 
Open "System Preferences" then open the "Security" pane.

Under "General," do you have "Log out after XXX minutes of inactivity" enabled?
 
Go to system preferences/energy saver and click the schedule button to see the computer is set to shut down at certain times.
 
The next time it happens (or hte last time it happened if you can trace it in the logs), go to Console (/Applications/Utilities) and in its logs (all or system log) back in time when it shut down. You can find that e.g. searching for shutdown and it should list some cause.
What does it list? Post the line with the shutdown cause and something before it - some lines before it there will be somehting about kernel loading etc. Before then, there should be the last lines of the system before it actually shut down. (better too much text than little if in doubt).
 
Here's the shutdown cause:

Jan 12 00:58:48 localhost kernel[0]: Previous Shutdown Cause: 5

Here's the last bit of the log in case it is of some use. Like I said, the computer will shut down, without fail, at slightly over a minute of inactivity. If in continuous use, everything runs normally.

Previous shutdown cause is reported always after the system is started and starts the services... in the example above, the logs start about the moment the system was started, so the last commands given to it before it received the shutdown signal aren't included (they'd be before - whenever there is a break of time before the last commands and the powering on). But we can see something

Jan 12 00:58:48 localhost kernel[0]: Previous Shutdown Cause: 5
Sleep called for the shutdown in this case.

Was there also before the shutdown line something like below?
kernel[0]: Previous Sleep Cause: 0

Finding a correct translation for the numbers in the shutdown cause is always a nice treasure hunt, for number 5 this is what I think covers it as much as it's ever been covered even in a semi-public view. Which will still leave a lot of open ends to find the exact cause in this case.

What does system profiler show for the battery? Voltage in full charge, cycle count, is it seen correctly?
Does the Mac get hot in use?
Do you have any usb hubs connected to the Mac?
Any peripherals? If there are, it would be worth testing with nothing attached to it (not even an external mouse).
Any remote services enabled? Remote login, or remote desktop etc?
Any difference if you are using battery or are connected to the mains?
Any difference for other users on the Mac? If there aren't other users, create one (and it can be deleted later).
Any unusual programs or services that could be running? Any torrent services, anything like Parallels or Fusion or VirtualBox? Games?
I guess we could eliminate the services as a cause if running the Mac in safe mode (boot with shift until you see it's starting in safe mode), with nothing attached to the Mac, and it would not happen there.
 
I&#8217;ve put my responses in bold:

I copied and pasted all of the log. I also noticed there wasn&#8217;t anything regarding before I booted up last. There is nothing like the &#8220;Previous Sleep Cause: 0&#8221; you mentioned.

Finding a correct translation for the numbers in the shutdown cause is always a nice treasure hunt, for number 5 this is what I think covers it as much as it's ever been covered even in a semi-public view. Which will still leave a lot of open ends to find the exact cause in this case.

What does system profiler show for the battery?
Voltage in full charge, cycle count, is it seen correctly?
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 5098
Remaining Capacity (mAh): 3672
Amperage (mA): 1680
Voltage (mV): 12155
Cycle Count: 445
Does the Mac get hot in use?
Not really&#8230; it warms up slightly after continued use, but nothing major or any more than any other computer.
Do you have any usb hubs connected to the Mac?
No
Any peripherals? If there are, it would be worth testing with nothing attached to it (not even an external mouse).
Nothing attached
Any remote services enabled? Remote login, or remote desktop etc?
No

No difference

Nope

I did this, and the shutdown still happened.

This one is a pickle!!!
 
Older logs would be under the archive (from the logs sidebar in console).
Hm... not battery, not a user specific thing, and happens in safe boot. :-/
You said you had done the hardware test and it reported nothing.
Did you run it once or multiple times? It's usually best run in looped mode with extended test at least for a few hours. Is it possible to test run it for a few hours or an evening?
When you boot to the hardware test and don't select anything (and let it get idle) will it still do that?
Or if booted from an OS install disc? Don't select to install anything but let it get idle...
 
When I ran the hardware test last it did not shut down. I actually left the computer alone to see if it would.

I'm not sure about running from the install disk; I'll have to check that.

I'll run the hardware test again this evening and give a report! :)
 
Hi jcbar!
I have the same problem with my Macbook. Did you find a solution?

These are the specs of my Macbook:
Modellname: MacBook
Modell-Identifizierung: MacBook1,1
Prozessortyp: Intel Core Duo
Prozessorgeschwindigkeit: 2 GHz
Anzahl der Prozessoren: 1
Gesamtzahl der Kerne: 2
L2-Cache (pro Prozessor): 2 MB
Speicher: 1 GB
Busgeschwindigkeit: 667 MHz
Boot-ROM-Version: MB11.0061.B03
SMC Version: 1.4f12
Seriennummer: 4H61913AVMM
Sensor für plötzliche Bewegung:
Status: Aktiviert

I am running Tiger 10.4.11, all updates installed.

It happens at about 65sec after the last activity (mouse / kbd) and you have 5sec to click on the "Cancel" button - very nasty!
It happens when running off the battery or AC adapter, battery installed or not. I can confirm it happens when started in safe mode (<SHIFT> during boot).
 
I found the problem for this behaviour: it is the keyboard. After replacing the KBD my Macbook behaves normally again.

I hope this helps other users...

Johannes
