Imac automatically switched off???

I installed airport extreme in my old imac g5 and it worked perfectly.
Since I also use my macbook pro, i seldom use my imac G5 until recently. I discovered that after about 3 minutes working, the computer automatically switched off. When restarted, the same problem re-occurs. Has it got anything to do with the installed airport extreme...i dont think so.
Can someone help?

Hi, and a Warm Welcome to Apple Discussions and the Power Mac G5 Forum!
You could try browsing, searching or posting in one of the iMac G5 Forums
http://discussions.apple.com/category.jspa?categoryID=134
where there is some discussion of similar issues.
You could check Applications > Utilities > Console - system.log for entries at around the time of the shutdown.
You could try an SMU reset

There is a repair extension programme which may apply

  • When I connect to wi fi does my 3G automatically switch off. As I seem to be using a lot of my data when using wi fi at home

    When I connect to wi to, does 3G automatically switch off my iphone4s as I seem to be using a lot of data even when using wi fi at home ?? Thank you

    Hi,
    As far as I know, when you have a WiFi-connection all data will go through WiFi and therefor will NOT use your 3G data.
    Kind regards,

  • My iphone does not automatically switch off the display light when locked. How do I fix this?

    I have an iPhone 5 with iOS 8.2 software.
    My iPhone does not automatically switch off the display light when it is locked. Therefore, if I get an e-mail/text message/pop-up from other application, the light just stays on, which obviously drains my battery.
    The problem just started yesterday, and it has been a couple of days since I updated the software, so I wouldn't think the software update is the problem.
    I have tried restarting the phone (using home and lock button), but that did not work.
    Something else that seems weird is that once in a while, a blue beam rolls over the screen from one side to the other. I don't know why it does this, and have no idea whether this is related to the display light issue.
    I hope someone is able to help by telling me what to do in order to get my phone to act normal again.
    Thank you x

    Restart your device by holding the home and power button until the Apple logo appears. You will not lose any data.

  • Nokia lumia 620 automatic switch off

    My lumia is automatically switch off and then i have to open the battery than again place the battery then its only switch on

    Take a look of the battery contacts insde the battery. Due to wrong inserting of the battery the + contact spring may bend (the to metalsprings are too apart from each other). Try to press them together (not to much) or replace your battery.
    Do not insert your battery in an oblique angle. Locate you battery parrallel to the battery compartment while inserting it.

  • N8 Automatic switch-off. Help please

    whenever i start some of my phone applications, like web, make a call, receive a call, start maps, my phone automatically switches off even if the battery is full. And when i restart my phone, it switches off again after displaying the nokia logo or just after the main screen is displayed. The same process continues repeatedly. Is my N8's battery not working correctly???? Do i need a new battery?? plz help!! 

    Forgot to say, if you can, try a new SIM card as there have been reports of similar problems with old SIM cards.
    Also if Nokia care have wiped their hands of you it may be worth going through the hard reset, reinstall / change firmware process.
    Google the process it can't be discussed here.

    Thank you

    ... because of the annoying Cursor-jumping when you write a text and accidently touch the pad. But thanks for your answers. I'll stay with "Fn & F9".

  • Device get Automatically switched off and unable to turn on ...

    Hi experts,
    I wish u happy new year to everyone..
    I am facing a critical issue in my bb torch 9860,device get automatically switched off and unable to turn on the device by switching the power button .after doing hard reset it turns on ....iam missing calls .please help me how to trouble shoot it

    It's obviously a software issue so I suggest jumping right to an OS reload.  Battery pulls are always a good place to start but after that you should reload the OS.
    To do this, plug your phone in to your PC and open BlackBerry Desktop Software.  Click Device at the top of the software then Restore.  Choose the most recent restore point and load it.
    Let us know if that helps you. 
    - If my response has helped you, please click "Options" beside my post and mark it as solved. Clicking the "thumbs up" icon near the bottom of my response would also be appreciated.

    Hi sumit1310,
    Thanks for visiting Apple Support Communities.
    I'd start with these troubleshooting steps:
    iPhone: Hardware troubleshooting
    http://support.apple.com/kb/TS2802
    Will not turn on, will not turn on unless connected to power, or unexpected power off
    Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
    Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    After at least 15 minutes, if:
    The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
    The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
    If the display turns on, go to step 4.
    If the display remains black, go to next step.
    Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
    Regards,
    Jeremy

  • My 27inch iMac automatically shuts off

    My 27 inch iMac will shut off automatically after about 30 to 45 minutes - it will not turn on when using the on/off power button.  I have to unplug from the wall, hold down the on/off power button for 10 seconds, plug it back into the wall then usually, it will turn on.  I have tried using different wall outlets and not using a power strip but unless i follow the previous steps, it will not turn on. I ran an apple diagnostic test - it showed no issues with the hardware.  It was purchased from the apple refurbished store in April of 2013.  For hardware -processor 3.2 GHZ quad core intel core i5 - memory 8GB 1600MHz DDR3,  graphics - NVIDIA GeForce GTX 675MX  -software - OS X, iLife '11

    I think you should have received a 1 year warranty on this Mac, so I would take it in and have them fix it for free. If this is happening routinely at about the same time after boot up it sounds like an overheating issue, which is most likely hardware related.

  • IMac 333Mhz switches off shortly after switching on

    I have a selection of old Macs, among them an iMac 333 Mhz tray-loading bondi blue. Whe I switch it on, it gives the chime and then switches off again. I suspect it has to do with the power supply, but I have no way of testing this. Any ideas what could be behind this?

    It may be a shorted out flyback transformer. That is a problem with the first four versions (tray loaders) of the iMac. It has been reported here a fair number of times. With my Rev B (233 mhz) I was able to unplug the internal monitor (big multi-connector plug) and it booted all the way. Of course I couldn't see anything that way but it did confirm the fly back short. Those models don't handle heat well and tend to burn out after 4 or 5 years. After that I bought a PC monitor and adapter plug and am able to get some further use out of the old iMac.

  • IMac crashes. switches off with a loud 1sec buzz every 15secs.

    iMac crashing with screen going black and a regular 1 second beep obout every 15 seconds. It can only be restarted by switching off the mains supply. The fault occurs at any stage of computer operation i.e. typing, reading files, manipulating graphics, and even when in screen saver mode. Anybody help?

    I believe it's a RAM problem.  Try taking out the RAM and then putting it back in.  Maybe they came loose.  If that doesn't work, if you have 2 RAM sticks, try taking 1 out and restarting.  If the beeping/crash goes away, the other stick of RAM is bad.  If it does crash, try the other RAM stick.  You could try new RAM (which is pretty cheap these days).  If all else fails, it's probably an issue with the logic board and it will need repairing.
    Good luck!

  • My iPhone 4s automatically switch off and cannot turn on. It happened 5 times now

    My IPhone 4S with 7.0.4 goes off automatically. It happened 5 times as of yesterday (11/02/2014). I went to repair shop, they connectc to their computer and gives me back within 5 minutes problem solved. I asked them what is the problem. They never revealed. Are they paid by Apple Inc.? What is the problem?

    thanks, hope it will help me.
    Actually when it is off, I cannot switch on. Once I was in the field and it went off. I kept it idle for whole night and next morning it is on by its own. I dont know why.

  • Since Yosemite upgrade, my iMac automatically logs off.

    After the upgrade to Yosemite from Mavericks, my iMac (2011) will log off my account after a certain amount of time.  The preference to do so is NOT checked. I have tried checking that preference, logging out and in and then deselecting that choice, logging out and in (this seemed to be advice to help other issues).  Nothing seems to keep it from doing so.  It is my Administrator account (the computer's at my house, so I'm not concerned with unauthorized access).  My laptop, also upgraded from Mavericks, does not have this issue.  I have installed at least one update since the initial release.
    Any help??
