Random power failure / shutdown?

Hey all,
I recently purchased the 20" 2.4 GHz and have been experiencing random power failures. Right in the middle of typing an essay or watching a movie, my computer turns off unexpectedly. Has anyone else experienced this problem or know what might be going on? The only things I could think of are static buildup/discharge in the power supply or overheating...
Thanks!

I have a iMac G5 (purchased 5/05) and I never had an issue with it other than having to manually connect to my home network) Recently (last week) I called Apple Support about my network issue and we did a commandoption+PR during powerup. This is the first time it was ever performed. Since then My iMac turns off (completely) randomly. It doesnt matter if I am surfing the web, watching a movie, or the machine is idle doing nothing, and BAM no power. I'm glad I bought the 3 year Apple iCare package, because it seems that Apple knows in about 3 years, the machines begin failing.
I performed the SMC procedure about 30 minutes ago. I will update this post if I no longer have the loss of power issue again.
That vintage of iMac (and eMac) had a problem with bad capacitors (the problem hit other manufactureres than Apple, too.) If you open up the case and look at the logic board, see if any capacitors (the little barrel-shaped doodahs) are swollen or leaking brown fuzz. If so, Apple had an extended repair program for that, although you're lucky you have Applecare. If you're not comfortable opening the computer (that model is easy, just 3 torx screws along the bottom edge, though it's a little tricky getting the cover back on when you're done), definitely take it to a Mac tech ASAP, as this gets worse with time.

IMac i7 random power failure?

Hey there, my iMac 21,5 i7 has a random "sudden power failure", which has been diagnosed by an apple maintenance centre as a 'Logic board" problem. It was bought in Jan 2012 and it is plugged into a power surge/no break protection.
I've reset the SMC, changed power chord, power outlet and in the end took to one Apple maintenance centre in Rio, where I live, and the dignose was a deffective Logic Board, the solution being a replacement... which means it might be better to buy a new one... An apple computer that lasts ONLY ONE YEAR???
Does anyone have experienced similar problems? Any different feedbacks? Suggestions of apple techs in Rio de Janeiro???
Thanks in advance!

Hello, sad case, but Macs aren't what they used to be, & yes, without AppleCare, a Logic board replacement will be terribly expensive.
Can only say that everybody needs to get the 3 year extended Applecare when getting an iMac or Laptop.

IMac random power failure

HI all - Help!
i Have a 2012 iMac.
Once or twice in the last few days it shut off on me randomly while I used it without warning. I thought it was a quick power outage but by the 3rd time it happened I looked at everything else plugged into the same power strip and it was staying powered. I plugged the imac directly into the outlet and same result. As well as plugging it into another outlet on another circuit. The issue is the computer - not the power its feeding from. We havent had any thunderstorms in the area for a week now so it wasnt caused by a storm. There were no tell-tail signs of strange happenings before this happened either. I DO use boot camp on it and PC game regularly but I have made sure the computer never overheats. So I couldn't have fried anything to the best of my knowledge.
Now here I am a few days later and i cant even get the computer to finish booting up before it will lose power. Any clue on how to fix this? I dont have apple care (Ive never once had an issue with an apple product) and I dont have the money to just go buy a new iMac. Has anyone had this issue before?

It could be a more serious problem, but it kind of sounds like maybe a bad, loose or partially seated RAM module.
If you have upgraded or added RAM, do and test each of the following steps.
1. Check to make sure that all the modules are firmly seated in there slots.
2. Check for a bad module, install the modules one at a time in the top slot.
3. Install the original modules in the original slot that they came in.
If you did not upgraded or added RAM, you can do step 1 before making a Service Appointment.
1. Check to make sure that all the modules are firmly seated in there slots.

Random power failure.

sorry i am a noob, i have recently been having a problem with my mac just turning itself off. i happens out of the blue when i am only running menial tasks such as watching videos or browsing the internet. its not a problem with it restarting it just plain turns off as if someone has pulled the plug. if anyone has any suggestions or is experiencing the same thing please help.
thank you in advance.

Hi again,
We all need a little more info. How long has this been going on, did it just start, has it always done this since you purchased the iMac, does it happen around the same time each day, does it happen after a certain amount of time using the Mac, have you recently moved it, does it only happen when you watch videos and surf the net, etc etc etc...
If this has been an ongoing problem, I would try a new outlet. If this just started recently, I would make sure the power cord is firmly seated. If recent and you have not changed your normal routine, I would suspect a possible power supply problem. It's hard to tell until you tell us more details...
When you're watching videos or even surfing the net and watching youtube or something like that, your Mac uses a little more CPU power which will make it run a bit warmer, when a Mac reaches continuous and unusually high operating temps, it will shut off for self protection... *but watching videos and/or surfing the net should not normally cause this.

A UPS model that works with Mac Native software to do a graceful shutdown and automatic restart during a power failure.

I've tried 3 UPS's (2 APC and one TripLite) that state they are OSX compatible, however, they do not fully respond to the native osx setting in (system Preferences/ Energy Saver/ UPS/Start up automatically after a power failure). This is what happens:
During a power outage, the OS does a graceful shutdown, but does not reboot when power is restored.
Apparently, the UPS is not notified to turn off during the shut down process. The power (on-Off-On) cycle is required by the mac to restart.
Trip lite tech support says they have software that works with Windows and linux to do this, but not mac.
I've tried two older APC UPS's, One Smart UPS1500 and a Back-UPS 1500 with the same result on two different servers and one iMac.
At this point I'm looking for a make and model of a UPS that does work. If anyone can verify a make and model that actually does this, I'd greatly appreciate it.
Its a simple test, just pull the plug on your UPS, wait for the system to shut down, and then plug the UPS back in. The system should reboot.

Many of the CyberPower UPS units are compatible. Checkout the home solutions on this page: http://www.cyberpowersystems.com/products/ups-systems.html

Does iMac shutdown nicely on power failure?

I have heard that the iMac 5K 2014 shuts down automatically on detecting mains power fluctuation. Great if this shuts down the 128GB SSD in an orderly fashion. If not I may have to get a UPS, though one I can afford could be unreliable! How paranoid should I be about this?
I do have Time Machine on. Loss of my unsaved data is an acceptable risk, and not what I am concerned about here: I am worried about maintaining iMac system integrity.
So, can someone please enlighten me about automatic shutdown of the iMac?

Tim Durbridge wrote:
That's reassuring.
But does the iMac shut down automatically on power failure?
Does that protect the system well enough for practical purposes?
Would that be why you operate a computer without a UPS?
The iMac does not have an internal battery or UPS. It will NOT shut down automatically or otherwise when power is lost. If you lose the mains the computer immediately stops working and serious corruption can and has indeed happened. Think about what you said. You lose main power to the machine. It has no power of its own, no internal reserve supply (and I know of no personal computer that does). It may or may not recover when power is restored and it depends on what was going on at the time the power failed.
If data loss or corruption is is unacceptable then a UPS is a must have. A UPS will allow the machine to shut down properly. OS X has built-in UPS power management software. You can set the computer to properly shut down when the UPS reaches say 20% reserve power.
Buy the best UPS you can possibly afford.

Application got locked when power failure(abnormal shutdown)

hi all,,,
I am developing swings application where user needs to login by giving valid Uname and password(only one user at a time,multiple users not allowed) and im storing this data(Uname and pwd) and status(looged in/not) in xml,my app is working fine when we closed the application normally,for this i had written an event when clicked on close button(by using boolean).
My problem is when there is power failure/system crashes,the application is getting locked when user tries to login.
can any help me in this..wat can i do to solve this?

I found that problem
i hope your application will be running in a network drive and only one user can login at a time.
so u need to track the abrupt shutdown.

Cascade shutdown of multiple ix devices during power failure

I hope there is an answer for this.
I have an ix4-300d and ix2 currently, both mounted in the same location. The ix4-300d is connected via USB to my APC Back Ups PNP 550va unit. During a power failure my ix4 shuts down gracefully while my ix2 keeps going until my UPS goes flat at whcih point my ix2 crashes hard.
Is there some way to get the ix4-300d to remotely signal the ix2 to shut down?
I understand these units run an abridged version of Linux of some flavour?
If that's the case then it should be trivial to add a script to remotely shutdown all Lenovo NAS devices on the same sub-net?

Hi wallythacker,
The only way I know of to shutdown all the devices on the same subnet is through a system monitoring software. I am not familiar enough with any specific software to recommend any, but there are free versions or expensive versions just depending on what you need. You might need a USB hub though because some of our devices cannot be shut down via ethernet, only by USB.

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:

Problem with iMacs loading web pages slowly after a power failure

We have 3 intel Macs (2 iMacs and a MB) on our network.
Today we had a power failure, and now we are having problems with both iMacs loading some web pages slowly (in Safari and Firefox both). I have shutdown and restarted both iMacs to no avail. As you will notice, I have not experienced any problems with my MB probably because the battery never allowed it to shut down completely.
Can you give me any indication of what the problem is or how I can go about troubleshooting this further?
Thank you in advance.

It does sound like it could be a WiFi issue. You can try rebooting your router and that might help. It just might your Internet connection or the router itself. If the router is bad, you can replace it. If its the Internet connection - you can only do what you ISP allows you to do.

What is a neat way to delete a stale amavisd pid_file on first boot after panic or power failure?

Lion Mail Server component postfix/smtp 100% reproducible blocks inbound smtp mail delivery on first boot after a panic or power failure.
Error messages from mail.log are like:
postfix/smtp[45785]: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused postfix/smtp[45785]: 2F7131F9A97: to=<[email protected]>, relay=none, delay=76041, delays=76040/0.36/0.05/0, dsn=4.4.1, status=deferred (connect to 127.0.0.1[127.0.0.1]:10024: Connection refused) postfix/error[45790]: 550D61F9A99: to=<[email protected]>, relay=none, delay=76040, delays=76040/0.39/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused) postfix/postscreen[45872]: NOQUEUE: reject: RCPT from [100.200.100.159]:65392: 450 4.3.2 Service currently unavailable; from=<[email protected]>, to=<[email protected]>, proto=ESMTP, helo=<host.domain.tld> /usr/libexec/postfix/greylist.pl[45885]: Temporary message rejection to: <[email protected]> from: <[email protected]> sent from: [100.200.100.159] for: 60 seconds due to greylisting postfix/smtpd[45879]: NOQUEUE: reject: RCPT from host.domain.tld[100.200.100.159]: 450 4.7.1 <[email protected]>: Recipient address rejected: Service is unavailable; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<host.domain.tld>
The issue seems to be related to the amavis content filter due to the connection to port number 10024 and amavisd being configured on that port. Amavis.log:
/usr/bin/amavisd[236]: (!)Net::Server: 2012/07/25-13:38:49 Pid_file already exists for running process (88)... aborting\n\n at line 277 in file /System/Library/Perl/Extras/5.12/Net/Server.pm ... /usr/bin/amavisd[236]: Net::Server: 2012/07/25-13:38:49 Server closing! ...repeating roughly every 10 seconds...
The workaround is to reboot the machine, after the second boot the inbound smtp mail delivery is no longer stuck.
The issue seems to be related to http://serverfault.com/questions/138690/amavisd-net-server-pid-file-already-exis ts-after-system-crash-and-startup
How to permanently fix Apple Mail Server to accept smtp inbound messages on first boot, by removing the left over amavis pid_file from the previous unclean shutdown?

Use connection pooling. This will put the connection management in the hands of the webserver, not your code. Check out this post:

Power failure

Hello,
The server on which is installed the database has the HDD in a RAID matrice ( one HDD is mirrored by the second). In present the only backup is an export which is made every night. In the near future this will be by completed with a cold backup.
In case of a power failure all netowork is off so there is no connection to database server. If there is no personal which to stop the database is there a risk of database to be damage when the server is shuting down after a time ( the exisiting UPS have a limited capacity).
Thank you!

Oracle databases are designed to cope with such an event. A graceful shutdown is always the preferred option but if the server was to lose power Oracle will cope and do a crash recovery on startup. However, manual recovery is sometimes necessary in extreme cases.
You really need to get your backup strategy in order just in case things went horribly wrong. Export is NOT a backup strategy.
Also, you may look into using software in conjuction with your UPS. When you lose power the UPS can talk to your servers and instruct them to perform a graceful shutdown after a certain time. Talk to your UPS supplier. They will be able to recommend which software to use and the extra hardware required.

When the program gets terminated unexpectedly (power failure, UPS fails), when I reopen it, it usually does NOT return the previous pages, as I have checked in the 'options' box,

# Question
When the program gets terminated unexpectedly (power failure, UPS fails), when I reopen it, it usually does NOT return the previous pages, as I have checked in the 'options' box, but goes to some random collection of pages often from months ago. Very frustrating - can anything be done to COMMAND it to save current pages and re-open there? (As I said, I have this box checked in the options, but it does not work ..

Very Important, how much Free Space is on your Hard Drive first of all? Click on the Macintosh HD on the Desktop, then do a Get Info on it.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
Do they launch OK while in Safe Mode?

Restore/Repair Jabberd / iChat server after power failure

SLS 10.6.1 on Mac Mini.
I've had this happen twice, but in different ways. We've had some storms come through and knock the power out recently. Everything seems to come back online fine, except for iChat server (jabberd of course). The first time, I was getting errors about c2s and sm not being able to connect to, well, itself. I was never able to actually fix those, I have to reinstall the whole system.
This time I'm getting similar errors where the system isn't talking to itself properly. Here is the log from clicking "Start iChat" to trying to connect from client.

This is what it does when I try to connect from a client. The client just keeps getting a username/password prompts over and over. (12.34.56.78 is of course a made up IP) It will do this repeatedly with a different port number, going higher and higher. In some cases it will add "is being rate limited" This will just loop and loop until I shut iChat and Push Notifications down.

Is all of that supposed to bind to 127.0.0.1? Another posting on here said to try and reinstall just the serveressentials.pkg from the disc. I tried that on a previous install and it didn't seem to do anything. Is there any kind of repair or restore script that can be run in situations like power failures where the thing doesn't shut down gracefully? jabberd seems pretty delicate.
Thanks in advance

It was working perfect before two things - power outage, and I had turned on the Firewall service because I wanted to see how it worked, but it's turned off and not even an active service.
Thanks in advance for the attempt!

G5 Power failure during start up and wake

I have an early G5 20" non-iSight iMac that has a power problem that is steadily getting worse.
As Apple support has expired and can't be extended, I'm at a loss how to resolve this.
Description.
The problem first started as intermittent during wake up from sleep (power light pulsing). I'd move the mouse or tap the keyboard to wake the iMac and I'd hear the disk just start to spin up followed by a sharp 'pop/click' like the power cord had been pulled, and it would be powered off needing the power button to be pressed to restart from scratch.
Now the problem has worsened in that occasionally I will find the iMac has completely powered down during sleep. When I restart it can take up to 6 or more attempts to get to the point where I can use it. There's a sequence of restarts needed, each starting from pushing the power button, and then ending during the starting sequence with a 'pop/click' as the power suddenly shuts off. Each time the start up will progress a little further than the previous attempt until eventually it finishes building the desk top after login and I can operate normally until the next time I find it powered off after a few hours of non-use. The power failure starts initially from just after the welcome chime, and progresses to maybe 5 or 6 times later to during the desk top build after log-in. However, once logged in and operating the iMac behaves as normal, switching users, log-out and login, screen save and wake from screen save etc are all as I'd expect. I've not (yet at least) had any sudden power failures during normal operation.
The serial number of the iMac falls within the Sept 05 Repair Extension Program serial number range (not EMC 2056 though), but when I spoke to Apple Support they said that the lack of random behaviour meant that the problem I'm having is not related and so would not be covered by this program.
So I'm kinda stuck with a problem that is annoying when it occurs, which is daily at the moment, although it's been this bad a few weeks back and then was fine (iMac left switched on for 2 to 3 weeks without a problem) until we had a power cut earlier this week, and it's started again.
I've searched through the forums and while I could find plenty of references to 'Sudden Power Loss' none seemed to be as predictable and similar to this one.
Suggestions and ideas welcome. Thanks.

i am having a similiar issue. I have the same exact computer (iMac G5, non-isight) and it stays on for 30 mins, hour, 3 hours and shuts off. Upon starting up, sometimes it doesn't make it to the login screen before shutting down again. I have downloaded heat temp monitor programs and it seems to get to about 70 degrees celcius sometimes. Upon restarting, I get the "report problem to apple" screen with this information. I have tried to restart the power supply too.
