  • I have a Macbook Pro early 2011 running 10.7.5, does anyone know why it sounds like the fans are spinning really fast and loud. It's not like I'm using many applications at one time. Thank you.

    Trying to see why the fans are spinning real loud and fast. I dont have a nearby Apple store to take it to and Bestbuy wants to overcharge you for a bunch of uncertified geek squad employees working on them. Any help? Thanks in advance.

  • Fan on fast and loud

    I've seen this issue posted a few times with no firm answers, so...
    My fan often runs very fast and loud....at those times I have noticed through the Activity Monitor (All Processes) something called "Quick Look Server" that has a listing of 98 to 99 in the CPU column; all of the other processes are in single digits.
    When the fan is quiet, the Activity Monitor doesn't have the Quick Look Server anywhere near the 98-99 listing.
    Any idea what the Quick Look Server does and whether it's the cause of the fan running loud and fast?

    in the Activity Monitor, there's a drop-down menu, and if you select "All Process" it will list everything that's up and running, in order starting with whatever is using the most of the CPU. Most of it is internal to the system but it also includes whatever applications are open.
    Whenever the fan is running high on my Macbook, the "Quick Look Server" is always at the top of the list, so I'd like to know what that is.

  • XServe fans running fast and loud

    Good morning
    I have searched the information base and tried a few suggestions without success.  Hoping for another solution here.
    I have an Intel based XServe (2008) (OS 10.6.8) whose fans are running faster (and therefore louder) than they have previously.  This follows on the heels of a power outage (two of them actually) here at school, though the server is behind a UPS.  The system identifier light is also blinking in a particular pattern - 4 flashes and a pause repeating.
    The server is up and running, teachers are connecting to it just fine, the RAID is intact and online, the drives all look good according to Disk Utility.  So, functionally, everything looks OK - the fans are just running faster and louder than before - noticibly louder than the other Intel XServe in the rack.  The server is at the top of the enclosed rack with a space below it as it has been for the last 4 years.
    This summer I took all the XServes out of the rack, opened them up, and blew the dust out of them (including a moth - truly a bug in the system), so the all the airways are clean and clear.
    I have tried the suggestions I could find on this forum:
         restarted a bunch of times
         shut down and disconnect everything (including power) for a period of time
         reset the PMU/SMC or whatever it is called doing the front panel buttons with the blue lights on the lower row
         reset the PMU/SMC or whatever it is called by holding down the power button while disconnected from power
    I have installed iStat Pro and the temperatures are averaging around mid- to upper- 30°C and the fans are running around 3000 RPM .  The temperatures aren't signifcantly different that the other XServe, but the fans are running about twice the speed.
    I had to reformat the RAID earlier this weekend and copy over the data files from backup and reassign permissions, but the server was running quietly after that was all finished.  It seems to be post-powerbump that the fans became noisy.
    Sorry for the long post, but I tried to include all the pertinent information.  I would have tossed in photos and videos if I could have!
    Any suggestions would be appreciated.
    TIA
    Greg

    Did a little more searching about setting up LOM on the XServe and I think I have it figured out now.
    I assigned a unique (different) IP address to Network 1 in the LOM dialogue box in Configure Server menu of Server Monitor since I only have Ethernet 1 enabled and linked to a switch using a unique (different) IP address for network traffic between the XServe and my clients.
    I can now see (via Server Monitor remotely) that I have a dead blower in my fan array which, upon closer inspection, is also evident in the iStatPro display (one fan running at 18 RPM).  Hence the blinking system identifier light and the other fans running faster and harder (and noisier).
    Oddly enough, I have a replacement fan array in a box of XServe spare parts.  I now have a weekend task.
    Thanks for all the information to be found and the people participating in this forum.  Love it.

    I suspect you didn't reset it right.
    Turn off the machine, let it charge up and then try the SMC reset again.

  • I am having troubles, when I open LR I get a message that there is an error and it will try to fix the error next time it opens, but I get the error next time it opens, and this is going on and on where I can not use LR, any suggestions?

    I am having troubles, when I open LR I get a message that there is an error and it will try to fix the error next time it opens. LR closes on it's own, I reopen it and get that same message next time it opens, and this is going on and on where I can not use LR, any suggestions? If I click on a different set of photos in the libary before I get that message I might or might not get the message next time it oipens, but I still can not get to those photos, and it is not just one or two but most of my photos. HELP!!!!
    Thanks

    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.

  • Is there an issue with Safari in Iphones and Ipads where it does not recognize option disabled="disabled" tag properly?

    Greetings everybody,
    I have run into a peculiar problem with the Safari browser on mobile platforms (IPad, IPod, IPhone) which I hope I can find a solution for in this community.
    I just launched a new website where I sell products with certain variations, for example please view this link: http://www.finerribbon.com/aegean-single-face-satin-ribbon.html
    On this particular product, the product variants are supposed to work in such a way where:
    If you select the value "1/8" from the "Choose Ribbon Width" field
    THEN
    The only options active and available to choose from in the "Choose Roll Size" field should be: 500 Yds, 20 Yds & Sample Swatch
    Now, if we browse to the above link in Safari using a desktop or a laptop, there are no problems at all, but if we browse to the above link using an IPhone or an Ipad, then we have a problem where all the options are available regardless of the values chosen, basically the above functonality does not work.
    I was told that there an issue with Safari in Iphones and Ipads where it does not recognize option disabled="disabled" tag properly, is this true? Can anyone advise me if there is a solution to this problem? I would sincerely apperciate it.
    Thank you very much for your time and help!

  • Mdnsresponder will not quit.  Consumes above 100% CPU and kills my battery.  Also causes my fan to run constantly and my computer to get extremely hot.  Force quitting doesn't work.  It just comes back.

    The mdnsresponder will not quit.  Consumes above 100% CPU and kills my battery.  Also causes my fan to run constantly and my computer to get extremely hot.  Force quitting doesn't work.  It just comes back.   I posted about this earlier and never got an answer.  Somebody, please help. 
    Thanks.

    mDNSResponder is a background process that runs all the time. If you kill it, it's relaunched automatically.
    Please launch the Console application and select "system.log" from the file list. Enter "mDNSResponder" (without the quotes) in the search field. Post a sample of the log messages in the Console window -- only one example of each repeated message, please.

  • Sattelite A200-1N9 fan starts running faster and become loud

    Hi,
    So i have strange problem. When my fan starts running faster he bocome so loud i can't work.
    What is more strange when he bocome loud i can't start any new programs and programs already running freezes.
    What kind of sorcery is this?
    Sincerely
    Per Aspera
    null

    Hi
    This happens because an process running in the background stresses the CPU up to 100% and this creates more heat dissipation and the fan kick on and runs faster to cool down the CPU. Additionally the CPU is locked and therefore the system freezes for some time.
    You have to check what process or tool stresses the CPU.
    You can start task manager (CTRL + ALT + DEL) and check the tab Processes.
    Here you can see in the CPU column what process use most of CPU performance.

  • Possible solution iMac cooling fan stuck on high and loud

    Had iMac go to sleep and just died, no lights or anything, power switch ignored me. Unplugging from wall, holding button in various ways on and after power up did not help in any way. Read articles on knowledge base and googled the web. Finally decided to pull out the round power plug on the rear of the iMac which to a regular user does not even look like it comes loose but it does. I checked the end with a volt meter and saw 120 volts ac and knew the cord was good. Plugged it into the Imac then momentarily touched the power switch and wham the iMac came on with a fury and the fan on super high speed. I'd never heard any of the iMacs in the house ever sound this loud, even on hot summer days. Pulled my hair out for a while but then repeated the steps removing the power cord from the back of the iMac, not the floor, and this time I pressed and held the power switch after plugging the AC back in and held it until I heard a beep, maybe 10+ sec. Of course I knew this worked because I could hear the iMac coming on quietly but making normal noises the moment I touched and held the power button. Now the system is working great again and I,m not looking at bringing it into a service center for no reason and injected more possible problems. I started another topic on the power on issue but I just wanted to document what I found and make it easier for someone else to get a search hit on a solution.
    Here's the other thread and hope it helps someone else.

    Do a SMC reset and if that doesn't fix it back to the store you go!
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • MacBook Pro fans stay on strong and loud

    I have had my MacBook pro for a year or two and never had this happen. Fans are staying on strong and loud for no aparen reason (just sitting on a wood table in a 68º F room as usual). A full shut down and restart did not fix the issue. A permissions repair and disk repair did not fix the issue. Any ideas?

    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    If this isn't the issue, then perhaps there has been a hardware failure or sensor failure. You can see if this helps: Intel-based Macs: Resetting the System Management Controller (SMC). If it does not then take it in for service.

  • Fan suddenly starts up and laptop starts lagging

    I recently purchased a refurbished 13' Macbook Air. It has been working perfectly until now. I stream shows on my laptop and suddenly the fan starts up really loudly and my laptop freezes and lags. It isnt overheating. I've checked the CPU. I also occasionally get volume issues where I have to restart the laptop to get it working again. Any suggestions?
