Unexplained power-off/shutdown

Hi, I have a year-old white MacBook, all has been great with it but this has happened a few times now which concerns me!
I went to use my Mac last night and mid-way through using Firefox the Mac powered down with no warning. No shutdown sequence, no low battery warning, it just went CLUNK and switched itself off, as if someone had pulled the battery from it. Upon switching back on all was fine and Firefox restored my tabs, TextEdit restored all my notes, etc. so it was definitely some form of unexplained crash!
Any ideas on what could be causing this? Is there a crash log somewhere that I could look at?
I can't see this being an overheating issue as I'd literally just come back to my Mac after leaving it in sleep mode for several hours.
Any help would be appreciated!

Hello,
Thanks for your reply - didn't realise the Console application even existed, should hopefully give some clues as to what this problem is.
I came home tonight to find my Mac had shutdown again after having disconnected it from the power supply before I left. The last few entries in the log before power off were these:
19/02/2009 18:36:26 com.apple.launchd[153] ([0x0-0x1ef1ef].com.apple.AddressBook.abd[3574]) Check-in of Mach service failed. PID 3574 is not privileged: com.apple.AddressBook.abd

If it was Adium it would be a fairly easy problem to fix, I'd just delete it along with all the preference files etc. but surely the address book wouldn't cause this?
Any help would be really, really appreciated as I have no idea what I'm looking for.
Cheers.

Updating system - do not power off. During shutdown.

Help.....when I shutdown my t420 and am conneced to external power, I consistently get a message during the shutdown process, something like "applying update 1 of 1. Do not power off or unplug your computer'. This is very consistent, happens every time, whether I have <knowingly> installed any updates or not. This causes the Thinkpad t420 to take a long time to power off.
I can't tell what is being updated or if this a real message or just some residual stuff from a past update.
any help/pointers on how to clear this would be appreciated.

do you have automatic windows update switched on in the control panel under Windows Update.

T430s on AC -- Shutdown restarts, not shut down/power off

I have a T430s running Win7 Home Pro.
On battery power, when I click Start, Shutdown the system shuts down completely.
On AC power, with or without the battery installed, when I click Start, Shutdown the system goes through the usual shut down stuff but then the backlit keyboard, ThinkLight and speaker/mic mute buttons momentarily light up and the system restarts itself. This is different from a standard Restart in that the lights come on during the start sequence.
I've checked the obvious (at least to me) stuff, e.g.
1. Power Button Action in Taskbar Properties, Start Menu is set to Shutdown.
2. Control Panel, Power options, Change plan settings, Change Advanced settings, Power buttons and lid,...
3. Control Panel, Power options, Choose what the power buttons do...
4. I even found a registry key, HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Start_PowerButtonAction
All of these are set to shut the system down. And yet the T430s restarts itself when shut down on AC power.
Any ideas on how to make Shutdown mean Shutdown and power off?

Solved!
Go to Solution.

I'm afraid this is probably no help for hausman, but I did manage to fix the problem on linux... The system would reboot instead of shutdown only when on battery (and only on Linux). I use Debian with the laptop-mode-tools package, which seems to be the trigger for the problem (the actual cause being some ACPI bug in the kernel, apparently). Until that gets fixed, this was my workaround (based on https://bbs.archlinux.org/viewtopic.php?id=133108). The solution is Debian-specific. It includes a solution for another problem (error messages about the intel gigabit module e1000e slowing down shutdown)
Create a file called shutdownfixes.sh in /etc/init.d, as root:
#!/bin/sh -e
### BEGIN INIT INFO
# Provides:          MIHAI
# Required-Start:

echo on > $i
done
echo "done."
echo -n "Removing e1000e module..."
lsmod | grep -q e1000e && rmmod e1000e
echo "done."
And make it executable:
chmod ugo+x /etc/init.d/shutdownfixes.sh
Then install it:
su
cd /etc/init.d
update-rc.d shutdownfixes.sh start 8 0 0 .
And the next shutdown on battery should be clean. Hope this helps someone.

ILOM feature "Graceful Shutdown and Power Off"

Hi,
We are using Sunblade 6250/6270s, with a stripped down SLES linux installed. We would want to be able use the ILOM feature "Graceful Shutdown and Power Off", but have failed doing this so far. What is required from the configuration and/or operating system to support this power off alternative? I have searched but not found any information on this topic.
Thanks,
Harri

The ILOM "Graceful Shutdown and Power Off" equal you press power button.
The SLES GUI (init 5) it will popup a window to let you confirm your action when you press the power button.
In the command line interface (init 3) when you press the power button your system Graceful Shutdown and Power Offed.

Random restart instead shutdown and power off in bios

Dear all,
since some time my Thinkpad T410 randomly restarts instead doing a requested shutdown. Also there is a random power off while POST when I power on the system (I not noticed any relationship between both problems except the date since they occur - maybe a system update, but I'm not sure).
I'm running Linux 3.1.2-1-ARCH with thinkpad-acpi kernel module and laptop-mode enabled.
I also tried Windows and Ubuntu to assure that this problem is not hardware related and I never experienced the problems with both tested OS's.
Has anybody experienced similar problems or a clue where to start looking for problems?
Cheers,
Martin

By now, i think i solved the problem with a clean arch installation. I know, it's overkill, but I can't figure out the cause of the randomly appearing problem.
@albLinux: If you have this problem when rebooting each time, try google or have a look here:

POWER OFF ISSUE K8 NEO4 PLATINUM (DON´T SHUTDOWN ALWAYS RESTART)

I have a strange behavior with my main board. It has worked well for almost three years. But now, I decided to change everything to a new case, and I decided to upgrade from XP to Windows Vista (no real upgrade, I format my hard disk and perform a clean install). And I have something very strange happened.
Every time I shut down the computer, performs the process smoothly, and when it goes off, the computer is restarted automatically. Do not stay off.
It's the same if keep pressing the power button for about two seconds. (in post for example) It seem to be shut down, the fans almost stopped immediately but the computer starts up again.
The only way to turn it off is to keep pressing the power button more than seven seconds. But I cannot turn off normally from the command “shut down” Windows.
I tried several solutions, without any success:
Try several power buttons on of different cases: Also, I have to manually shutdown the computer joining the pins of the ignition of the mainboard ( Not worry, I have been careful not to make any short circuit)
Test setup minimum, only memory, processor and video card. ( We also tried another video card and other memory).
Try different power supplies.
Disable all peripherals in the bios. (usb, parallel and com port, audio, lan, ATA, SATA, raid, IRD. IE1934, floppy, etc)
Change all possible power configurations of the bios:
IOAPIC Function (enable and disable)
MPS: (1.4 and 1.1).
ACPI Standby State (S1 and S3)
Video Off Method (all options)
Power Button Function (power off and suspend)
Restore On AC Power Loss (keep off)
Wake-Up Event Activity (disable everything)
I don´t changed or updated the BIOS. I have installed version 1.9. The last according MSI Liveupdate.
Actually, I do not know what to do. I do not think that is any configuration of windows, that this behavior as I have with the minimum configuration, without any operating system. Also disable all wakeup events of the network for nforce chipset from device manager in Windows.
The computer works fine on Windows, I don´t have any “death blue screen”, no hanging, freeze or problems with devices or drivers.
I need your suggestions and assist me with some answers:
Can the new drivers for Vista to make changes directly in the firmware of the components of mainboard? (Especially MSI chipset and Nforce drivers)
Will could have damaged somewhere in the process of changing case? (remember, the computer works fine in windows without errors)
Can I make a degradation of the BIOS firmware to an earlier version?
I will receive all suggestions and ideas to solve my problem. It is a good mainboard and I think ridiculous change for the inconvenience.
Thank you all for your help.
Josh

"Same issue with all PSU"
What stats they have? (Amperes per each line)
Also read Moan Guide and provide full details about your PC.
Have you tried with different memory stick?
"Every time I shut down the computer, performs the process smoothly, and when it goes off, the computer is restarted automatically. Do not stay off."
That means auto power on? Have you tried with mainboard out of PC case?(It could be shorting issue, or power switch issue)

I am loosing configuration when I power off my Cisco 857 router

I bought new Cisco 857 router from the shop. Router must have been used before as I couln't go in with default username/password cisco/cisco.
Well I followed instruciton and reset password to username and password. Now I finally connected to the Cisco CP express over my IE browser.
I found out that somebody was using a router from the shop so this is why I coun't log to it in the first place. Anyway problem is that when I changed configuration and applied settings it remembers it until I power it off. When I power it on again it remembers all settings from that shop.
It reverts everything back: IP address, previous level 15 account and password - everything like after password reset.
I tried it again and it again lost settings. So I found following instruction:
http://www.cisco.com/en/US/products/hw/routers/ps233/products_tech_note09186a00800a65a5.shtml
I followed it and changed again all settings on the router. My settings are again lost after power off/on. I noticed that when I do first bit it does show
0x2102 not 0x2142 like they think that is password reset mode.
Here is my output from Hyper Terminal:

Please help me as I am stuck and can't go any further....

Hi David White,
Alternatively, after password recovery you can modify the configuration to be what you want, and then issue:
   write memory
to save the configuration. You can then verify that your changes have been saved to the startup config by issuing:
   show startup-config"
The only good thing is that when I switch off a router it erase configuration except my new password which I created after password reset. Everything else is getting vanished (ADSL settings, DHCP, routing ) everything. Even new admin accounts I created.
Well have a question to your above comments. I am new in Cisco so please put as much detail as you can for me to understand. When you say modify configuration do you mean to go to Cisco CP Express graphical interface and then connect router to hyper terminal and execute above commands?
Why router doesn't remember this anyway. There must be some option to change in configuration to make thing permanent when I hit apply changes in Cisco CO Express otherwise it is pointless to heve it.
Phillip
write memory
is
copy running-config startup-config"
Can't this be done via Cisco CP Express or set up router to copy this every time I change this in graphical interface rather going to command line to achnoledge it?
I understand your concern about this router and somebodie's configuration details as you want things to be un-used when you buy them - true. ADSL details belongs to the shop which sold me the router so that is why I don't make a big problem about this. We take most of hardware from this shop and have discount and many good deals with them so I think they have been just testing it and forgot to erease their config. It might be that someone has returned router to the shop and they have repaired it and tested it.
I hope this is a normal behaviour of this router as I have option to replace it in case this is a fault.
Could you please write me step by step guide how can I make changed options stay permanently on router?
thank you

I have been able to wake my macmini by hitting the space bar - but since installing 10.7.4 using the 1.4Gb combo this wake method no longer works. Now the macmini shuts down, and I have to switch mains power off and on again before powering up the macmini

Since purchase of my macmini (2011 model) I have been able to wake it from sleep by hitting the (wired) keyboard space bar.
However, I recently updated the OS to 10.7.4 using the combo (1.4Gb) update, since when I cannot wake the macmini in that way.
Now, after putting the macmini to sleep, pressing the spacebar causes it to shut down.
I then have to switch mains power off and on again at the wall socket, after which the macmini starts up from shutdown condition.
I am by no means an expert, and have not been fiddling with settings, so I am in need of advice on what could need resetting to allow me to return to the previous simple 'wake up' approach!
Thanks.

After update my imac to yosemite automatically power off ifself.pls help

hi friends , I updated my imac (24-inch,Early 2009) to yosemite and update was ok.after update i restart imac then it is booting and showing apple log and coming to password page then automatically power off ifself. if i start with safe mode it is working fine. can everyone help me.

Hi.
You are running into a problem that many users of the 24-inch, early 2009 iMac 9,1's have encountered (including me). The Sudden Shutdown Syndrome is the scourge of many iMacs and Mac Book Pros.
Unfortunately, I believe that the only solution is for Apple/nVidia to revisit their geForce Tesla drivers and figure out if the power management is correct.
In your case, I'd try this:
1) Boot up your computer in safe mode and log into your user account.
2) In the Finder menu, select Go > Go to Folder...
3) Type: " ~/Library/Caches" (without quotes) into the box and press return. You will be taken to the Caches folder.
4) Select all the files in the folder and move to the trash (do not trash the folder itself). At this point, just leave them in the trash...don't erase them.
5) Go back to the Finder menu, select Go > Go to Folder...
6) Type: "/Library/Caches" (without quotes) into the box and press return.
7) Do the same thing you did in 4) This time, though, you will be asked for an administrator's password.
8) Restart your computer in normal mode and attempt login.
9) If you can log to the desktop, you may delete your trash.
Hopefully this will get you into your account. If it doesn't, you may have to do a clean install of Yosemite, go back to Mavericks, or wait for an update.
Good luck!

Survey: how do you power off your nano?

This is basically a quick survey on how people normally power off their ipod nano.
i have a 2gb black nano and have noticed some problems with turning the nano off by "holding the pause button" as this seems to reset my clock to 12am when i turn the nano back on after awhile.
so currently i just hit pause and let it sit and the nano shuts itself off eventually. so far i have had no problems with this method.
has anyone seen problems with this method or the other one? thanks!

hi jeff,
yes i have reset the nano multiple times and have even restored it multiple times. i think maybe the problem i am seeing lies in holding the pause button to shut the unit down, perhaps I am pressing too hard. i notice when i power it on after a "hold" shutdown, sometimes the power surges (its a loud power-on sound) and thats when the 12:00am appears. All the other settings remain the same as I set it, just the RTC resets. This problem never happened with a "automatic" shutdown...
The reason for this survey is too see if anyone else has this problem and what the more "popular" way of shutting down the nano is.

Harddrive still active at power off

Hello everyone,
I'm having an unusual problem with my HP Mini. When I go to shut down the laptop, it will proceed to run through the process with no problems until the end--the harddrive will start to spinup again right after POWER OFF is issued, and it then makes the noise that it would if I was making it force-shutdown by holding the power button. Not good.
I've spent the last two days searching the Wiki, google hits, and forums posts both here and on other forums and I can't find a working solution to the problem. What I think I want to use would be basically the same effect as running this:
hdparm -f /dev/sda
sleep 1
hdparm -y /dev/sda
Which would send the hdd to standby, and then shut it down. I've tried placing those specific lines in certain areas of rc.shutdown (middle and end of file, before and after the "/sbin/poweroff -d -f -h -i" line, which if it was working right should prevent this problem from happening anyway).
The problem is reproduced both with and without laptop mode enabled, and doesn't seem to be affected whether I shutdown from a cli or X.
One thing of note, it doesn't happen if I reboot, only shutdown. I can reboot, pop up to the grub menu and then hit the powerbutton and it shuts down "normal".
Which log files/script files would be useful in diagnosing this?

Thanks MadTux,
Scanning over the files, no errors are reported, I'm going to assume that the computer is doing exactly what I tell it to, not what I want it to.
Is hdparm the right way to control the hdd? I've heard of sdparm, I might try that, but the problem must be caused by some config file I'm overlooking...
EDIT:
The people at https://bbs.archlinux.org/viewtopic.php?pid=249653 have the exact same issue on an older kernel, and I get the same results when running the commands listed there. They mention a patch which will add a stop_on_shutdown file in the scsi harddrive's folder (for 2.6.22). Since I'm running a special kernel for my laptop (from 2.6.36), I'd rather not recompile it (Atom's suck), though I may do that in the end. I'll post back here if I find a working solution!

Notebook Taking a very long time to power off

Hi All,
My notebook (HP ENVY 17-j005tx Notebook) when shutting down only takes a couple of seconds, however it can take upto 5 minutes to power off...
At first i thought some service or program was taking a long time to shutdown, I installed Windows 8.1 SDK Performance Toolkit to try and identify a culprit; ran the command "xbootmgr -trace shutdown -traceFlags BASE+DIAG+LATENCY -noPrepReboot" and succeffully generated trace file.
I noticed the notbook had rebooted in just a few seconds..
Anyhow I proceeded to analyse the trace file using the wpa.exe program anf could not find any program or service taking much time to shutdown!!!
SO I understand now the Windows OS is shutting down nicely though the Notebook is taking a very long time to power off.
Anyone have any suggestions? I do have NVIDIA Driver 337.88 installed and did find another thread here where they suspected this driver version has not been tested by HP and after they applied it their notebook shutdown slower than usual - is this somehting maybe to look at...
I'm currently downoading sp63414.exe NVIDIA driver for my notebook - should I uninstall my current driver and apply HP's?

Thanks visruth,..
What I tried is run "msconfig" and boot into "safe mode", rebooted then shutdown, shutdown was back to normal again.
So then reran "msconfig" disabled all non-Microsoft Services, shutdown and again all powered off as normal (quickly after shutdown).
So rebooted and re-enabled all services again using "msconfig". THen disabled the following services, choosing these specifically as I'm not so sure why they should be running and some not know what they are used for...
rebooted and then shutdown and all shutdown and power off was normal...
It seems one of these services is causing the power off to take several minutes....
I suspect the bluetooth services, or the GSService, or IconMan_R, or possibly the Netgear Genie...
Funny enough I did uninstall netgear genie a few weeks ago and see for some unknown reason the Service is still there???? Hmm...

About auto power off function

Hello again guys,
long time no see ,since yesterday as far as I remember
Talking about Auto Power Off function , is there anyone that can tell us , it could be used on long terms - many days for example - as long as no one push the shutter or any button to wake the "beast" ?
This function completly shut down the camera or it's a kind of sleep function and some parts remain power supplied ?
Thanks,
Solved!
Go to Solution.

It's not completly shutdown. However, it should not cost too much power if any at all. I have it on for a week. Unless you turn on the GPS. With GPS turned on, even if you turn off the camera, it is still active.

Can my USB Drive be configured to power off when the iMac is powered off?

I am using a Lacie 500GB external USB drive. The drive remains powered on when my iMac is powered off. Is there any way to have the drive automatically power off?

Hello Jack
The s.o.p. for shutdown should be to eject the drive, turn it off then shutdown the iMac. The s.o.p for startup should be to startup the iMac then turn on the external HD. Many external HD manufactures do support a sleep function that allows the drive to sleep when the iMac is sleeping.
