What keeps making the cyclical noise while in sleep.  Sounds like iMac is loading a graphic or different screen.

What keeps making the cyclical noise while in sleep?  Sounds like iMac is loading a graphic or different screen.  Does it periodically while in sleep mode.  How do I correct this?  Just started doing it in the last few months.

I finally figured out how to fix this.  First I reviewed "Mac OS X: Why your Mac might not sleep of stay in sleep mode."  I noted the bullet:  "Do you have any other external USB or Firewire devices connected?"  I have an CP685AVR for a UPS for my Mac.  I replaced the battery a few months ago.  I also hooked up Apple's 'Energy Saver' power management software to the CP685AVR using the USB connection.  I disconnected it, and that solved the problem.  I still have the UPS and battery back-up; I just can't "monitor" the battery.  What's to monitor?  It always said the battery was 100% charged even right up to the time the previous battery failed.  Thanks for listening, uh... reading.

    Is it constantly beeping or is it beeping when you place it on the touchstone? If you place it on the touchstone and it beeps this is expected behavior. Also note that you could be bumping the device shifting it off the charger and then back on thus the beeping noise telling you that it has been realigned again properly and is charging properly.

    Syamak,
    You didn’t specify where the beeping noise is coming from. 
    If it’s coming through your speakers, you could try to update your audio drivers since it’s possible they’re incorrectly sending a signal to the speakers as the audio chipset enters standby. 
    If the noise is coming from the motherboard, you’ll need to take a closer look at your system’s configuration or contact the manufacturer.
    I hope this helps.

  • HT201250 WE KEEP LOOSING THE WIFI CONNECTION WHILE STREAMING TO VIDIO-HELP

    Why do i keep loosing the wifi connection while streaming to vidio- help

    Did you ever find a resolutution to your issue? I have a similar issue after installing Mavericks where the Arris modem goes to sleep when my iMac does, even though other devices on the network are actively requesting data. For the time being, as long as the iMac doesn't sleep the network is fine.

  • Pls Aadvice me  what is making the exception code 20 show up in the POs.

    Dear All,
    Need to know what is making the exception code 20 show up in the two open purchase orders.  The exception code is causing MRP to create requisition to order additional stock when we are already above MAX.
    TIA
    Kogi

    Exception code is to cancel the open Purchase orders. The req may be created due to some material master parameters- rounding value , lot size, safety stock, coverage profile etc. and maybe in excess of what is required. Check the material master.

  • How can I keep USB's ports active while in sleep mode?

    How can I keep USB's ports active while in sleep mode?

    OK, for some of you that may have the same problem or question as me. I have been testing my MAC Book Pro for ways to continue to power the usb while laptop in standby or off. I have found the following thing to work or not work.
    1. The laptop doesn't send any power to your USB's when it is powered off reguardless if it is plugged in or not.
    2. If laptop is put in standby no power is sent to USB's unless the power cord is plugged in on the laptop. So once again if you plug your laptop in and then put it in standby it does still send power to the USB's when requested.
    So the bottom line is, On my last laptop (toshiba) I was given an option to go into system preference and make a change that allowed my laptop to continue to send power to USB's when requested while in standby or powered off. I was hoping I could do the same thing with my new smokin Mac Book Pro but I haven't found that kind of option in the MAC.

  • A noise while playing, not continuosly like bad frequency

    While playing any song in itunes, it makes a noise, it sounds like the noise it makes when you connect your speakers to your computer [a little annoying sound], throughout the song... I need help. I've reinstalled it a couple times but the problem persists.

    It does not sound like a fan.  It sounds similar to a message sent on my iphone.  Call to Apple,,,, he had me force quit all applications.  The noise seems to have stopped but i still don't know which one of the apps was causing it.

    Mac Pro running OS x Lion 10.7.5 sometimes locks the network password while in sleep mode. We have tried resetting the password in AD and locally using keychain but the problem reoccurs. Any suggestions would be great.

    Also I unlocked the user account at 9:10am and by 11:10am it locked again. The user was away from his desk in a meeting.

  • The speaker on my new ipad mini keeps making a crackling noise when playing music or games and even just typing

    Has anyone else had this problem? It goes away for a while but when randomly starts happening again. Is this a common fault with the ipad mini or do I just have a faulty ipad? It is only 2-3 weeks old and never been dropped.

    Sounds like there may be an issue with the speaker, contact apple and see if they can help you out.

  • Audigy 2 ZS making bad "crackling" noises while playi

    Hi all.. I need help!!
    I RMA'd my Sound Blaster Audigy 2 ZS about 3 months ago and got it back, and it was fine for a while, but now its making severe crackling noises from all speakers whenever I play the game.. I've tried the speakers elsewhere and they are fine, and I've switched PCI slots several times, they still are crackling like crazy.. Totally ruins gameplay so I had to switch back to onboard sound.. Does this sound like I need to RMA it again, or is it possible I've overlooked something? It was fine previously.. My computer specs are:
    AMD64 3500+ Socket 939
    ABIT AV8 Motherboard
    024 OCZ Platinum Dual Channel 2-2-2-
    Twin 0K RPM SATA Raptors
    BFG 6800GT OC Video Card
    Sound Blaster Audigy 2 ZS
    Plextor PX-76A

    I need help ASAP! Thanks in advance!!!!Message Edited by duckdown on 07-20-2005 03:20 AM

    Not all of them, some suggestions just involve changing settings or changes in the BIOS. The settings may be named slightly differently on the various boards and BIOS versions/types.
    If it worked fine on that system but has suddently developed this problem then it's possible there is a hardware problem. If you made any changes at all, it might be good to undo them, or go back to a restore point to see if that helps (and see if it's a software change/setting that affected this).
    Otherwise I'd recommend contacting Customer Support so they can go over this with you in detail, one on one, to see what could be causing this.
