1.8 Power PC G5 Fan goes crazy and stays that way!

So this has been happening for about 2 weeks now. I've tried the suggested "Pull the power cord out and let the SMU restart" thing and that has no effect on it. I would rather not take it in to an Apple Store. Any suggestions? It will usually start up just fine and then give the occasional rev about 10 minutes after boot, then 15 minutes after boot its going all out loud fan noise. If I let it go, it will die down again...but then stop. My temperatures are fine.

Hi Cody,
Might be time to replace the PRAM Battery, 4 years is close to their lifespan...
See which one your G5 has...

  • HP7555 networked to Windows 2003 server goes offline and stays that way

    Printer sitting on my network via ethernet connection working OK for almost two years with same configuration.  Problem just started happening.
    Verified IP address and and was able to ping device.  Poked around with printer settings and server settings with no luck.  Restored server back 20 days and rebooted with the restored system just to see if something changed... problem still occurs.
    Have other printers on same server with no problems.
    If you send a test page to it, it will sit there with its offline status.  If you power off/on the printer the page will eventually print despite offline status but windows still says the page is in the queue.  Eventually the spool count drops back.  makes no sense to me.

  • Hello, my mac book air won't update. Every time i try it goes onto the purple starry screen and stays that way for hours, so i just have to shut it down. I have deleted a lot on my laptop so there is enough space, please help?

    I believe that system has a hall sensor on it to detect when the lid is closed so it can put the system to sleep and/or disable the monitor so it can be used with an external monitor only. If the sensor is marginal or has a bad cable, it may intermittently cut the monitor on and off, and may likewise put the system to sleep. One way to check would be to plug in an external monitor and if the laptop's screen cuts off or doesn't show up, start using the trackpad and press on a non-typing key like the shift key. If the external display suddenly pops and becomes active while the laptop display remains black, it's probably a problem with the sensor or the cable/connection. You might be able to fool the sensor into kicking on and off by moving a magnet over it. It's located on the left had side of the base with the unit opened up, and right over the audio output plug.
    I know of some people that put a small magnet right over the hall sensor's location so the laptop display turns off and they use the system with an external monitor, keyboard, and mouse. If fooling with magnets, make sure they're small and don't get them close to the hard drive because a strong magnet can wipe them out.
    I don't know if this will help you much, but it might.

  • How do I get the power manager settings to take hold? And stay that way?

    I want to have my computer awake while on the battery and while I'm driving my car.  To reduce distraction, I want to have the lid closed.
    In order to make this mode easy to get to, I created a new power plan that has the "lid-closed" event result in "do nothing".  Sometimes, this works.  Sometimes, the computer goes to sleep.  It is exceedingly annoying when the computer goes to sleep because I will get to my destination 45 minutes later and find that the computer didn't do what I wanted.
    I've also noticed that the setting for "do nothing" sometimes bleeds over to other power plans.  This is also a problem because, under ordinary situations, I would like my computer to behave normally.
    Here's a summary of the situation:
    1. I've disabled the "apply the settings to all power plans" button.
    2. I've created a new power plan called "Logging" that should stay awake when the lid is closed.  This power plan will sleep after 65 minutes and hibernate 10 minutes after that (on battery).
    3. This plan stays awake sometimes, but not other times.  At this instant, sitting in my living room, it refuses to stay awake.  Oops, just tried it and now it works (a little consistency here would be nice). 
    4. As a case example, this morning the computer behaved as expected: I arrived at my destination and it was still away and logging.  This afternoon, I woke it up and started logging, closed the lid, and drove off.  Upon reaching my destination, I discovered that the computer went to sleep as soon as the lid was closed.
    5.  The program I'm running logs data points.  When the computer sleeps, data points don't get logged.  Therefore, I know the computer is sleeping because, after a long logging session (45 minutes), there will only be a few seconds of data points (which correspond to the amount of time it takes to close the lid).  If the computer goes to sleep after 10 minutes or 30 minutes, there would be many more data points.
    6. When the computer hibernates or sleeps, it seems to remove whatever change I last put into the plan.  Even so, the plan still "says" that the change is there.
    Ultimately, the difficulty here is that I can't predict what the computer is going to do.  If I could, then I could adjust my use pattern.

    Try this:
    Go into Power Manager, choose the Logging profile.
    Go into Windows' Power Options, choose a different profile, then switch back to the Logging profile.
    See if this clears any contradiction between the two.

  • My C310 when powering up goes into "initializing" mode, per the printer screen, and stays that way

    I have a Photosmart Prem C310.  When I power it up, it goes into "initializing" mode on its screen, and stays there, with the little light beam circling the HP logo forever.  It never gets to the menu screen.  I can only power down by pulling power cord.  I reinsert power cord and it repeats the above symptom.  Any ideas, before I just junk it??
    Thanks!!

    Do you have it plugged directly into a wall outlet? If not, take it off of the surge protector and plug it directly into the wall outlet to ensure that it is getting enough power. Even if the prior set up is how the printer has always been connected; it can develop a problem over time by not being plugged directly into a wall outlet.
    The next step to take is to make sure that the light on the module is lit. I would then reset the external power module:
    Follow these steps to reset an external power module.
    Disconnect the power cord from the rear of the printer.
    Unplug the power cord from the electrical outlet, power strip, or surge protector.
    If the printer uses a power module with a detachable power cord, disconnect the cord from the power module.
    Wait 15 seconds.
    If the printer uses a power module with a detachable power cord, reconnect the power cord to the power module.
    Reconnect the power cord to the rear of the printer.
    Plug the power cord back into the electrical outlet. Do not use a power strip or surge protector.
    Check to see if the power module on the power cord has an indicator light.
    If the power module does not have an indicator light, continue to the next step.
    If the power module has an indicator light, make sure that the light is on.
    If the indicator light is off , contact HP to replace the power module.
    If the indicator light is on, try to power printer back on using power button. I hope that this helps.

    Boot off your Install Disk while holding down the d key, (not c key), then run the extended Apple Hardware Test.
    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc that came with your computer, 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. (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. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
    Some people get away without Repairing Permissions for years, some for only days.
    If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
    If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.
    May even need to do an Archive and Install if you have room on the HD...

  • Fan going crazy when booting

    When I boot up iMac, the fan goes crazy. After a moment it stops and is quiet again. I unplugged my power and plugged it in again but that does't work. I tried to start AHT by holding D when booting, but that didn't work. I didn't get any discs when I bought my Mac so I can't run AHT using the disc. How can this be fixed?
    I also have Windows 7 installed but I don't know if this is relevant. The fan goes mental everytime i boot up. It doesn't matter whether I do that with Windows or OSX.

  • Mac Os 10.6.6 update start the fans goes crazy

    Hi to all
    Some months ago (almost a year from now) my mac start to become hot after only a few minutes it started up and the fan goes crazy but I never realize why. I made some search on the internet but the only answer I found was using some software to reduce fan speed. It didn't work. I run the Hardware test but nothing strange. I also took my macbook to an apple certified repair center but they told me that nothing was wrong. I also ask to another repair center but same thing. So I left my macbook as it was with this super fan noise all the time. A quite disturbing thing but there was no solution and for what I'm doing my machine is ok so why change it? (It was the only solution they gave me)
    Last day my hd broke down so I had to replace it. I took my macbook pro a1211 model to an apple repair center they change the hd with a new one.
    So I reinstall everything for the beginning. I took my snow leopard dvd formatted the new hd, installed the os, iWork 2008, iLife 2008, Mamp, CSS Edit, Espresso, Pixelmator and few other application such as Firefox, Camino, Etc...
    I use the macbook with mac os 10.6, because I had to finish some work, and with my big surprise for two days the machine was super silent no fans, no hot body ..... nothing. I never reboot it and still no fans and hot body wow.
    Today I wanted to install the developer kit with ios 4.2 and so I had to update the Mac os x to version 10.6.6 as soon as I made the update after the reboot the fans start again to go like crazy and after 15 minutes of work the macbook body become very hot.
    The question is why?
    Anyone can help me?
    Thanks in advance
    Gianfranco

    HI R C-R.
    The apps i've installed are just a few. Espresso, CSS Edit, MAMP, TextWrangler,Firefox, Camino, Chrome, Opera,BetterZip, Stuffit Expander, Pixelmator, 1Password, Dropbox, Xslimmer, VLC, CyberDuck, littlesnitch, iworks, iLife, wacom tablet driver.
    Nothing more. All the software is updated.
    Here the data but as you can see nothing strange but fans are on at the maximum speed!

  • My macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated

    my macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated it should i update to lion?

    No, this problem should be solved.
    The MBP shuts down when too hot, to protect itself. First see if it is a process running astray: start Activity Monitor (in Applications/Utilities) choose <all processes> and click the %CPU column: are there processes that are using more than 50% cpu power? If yes click it and quit it, and tell us which one.

  • I am going crazy changing passwords that do not get recognized by the different services when it is time to use them, until I am asked to change the password again, until the next time I need to use it and it does not get recognized again. Is there any fi

    I am going crazy changing passwords that do not get recognized by the different services when it is time to use them, until I am asked to change the password again, starting the vicious cycle again: i need to use the password, it does not get recognized three times, then the system asks me to change it again, and again, and I am stuck!! Is there any fix for this "glitch?

    The first thing I would suggest is for you to go to the folder containing your catalog, using your system browser. There will be a folder that has the extension .lrdata. Delete that folder, and then try to start Lightroom. If that doesn't work, replace your catalog with your most recent backup.

  • Since Mavericks was installed I amd having trouble streaming and the fan kicks in and stays on when I am watching stream in features

    Since I installed Mavericks I am having trouble streaming and the fan turns on and stays on shortly into watching a film on line.
    Also the screen breaks up  into lines and colors with no image in the middle of viewing a film sometimes several tomes.

    Hi Mudra,
    Thanks for visiting Apple Support Communities.
    If your fan is running and you're noticing video issues when streaming video, I'd suggest first trying to reset your system, as described in this article:

    You can reset the Mac's parameter RAM and SMC.

    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try on another computer
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
