My computer keeps making a beeping sound and won't turn on??

I plugged my macbook pro into the power outlet and hit the power button in the top corner and it just keeps beeping. the light on the front of the keyboard part is blinking but nothing will come on the screen...

  • I was out of my room for an hour and when returning, my computer was making continuous beeping sound and was unresponsive.

    I am new to Apple, just bought the computer a month ago.  I extraced this from the log file.  I fear I've picked up some malware or been hacked...

    If anyone can help me I would greatly appreciate it.  Thank you in advance.  I am on an Intel iMac 10.8.1

    Since it's a new machine, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine. That also might apply to newly bought ones inside the first 90 days.
    FWIW, IMO, the AppleCare extended plan's the cheapest insurance you can get for your new desktop machine.

  • My computer keeps doing the usb sound and freezes

    My computer keeps doing the usb plug and unplgu sound, and when it does, the computer freezes.  I have tried update all drivers, and run one-key recovery but nothing helps. The system event logs only show one error:
    The embedded controller (EC) returned data when none was requested. The BIOS might be trying to access the EC without synchronizing with the operating system. This data will be ignored. No further action is necessary; however, you should check with your computer manufacturer for an upgraded BIOS.
    I tried to update BIOS driver and found it was up to date.  Does anyone eles have the same problem? It is very frustrating expecially when you are in the middle of a game.  Please Help!

    I understand what you mean about the sound now.  I was thinking of something else.  Sorry for the mis-understanding.
    Are these errors showing up in the System Event Log happening repeatedly ?  If there is just one or two of the same error showing up during the session you are on the computer that maybe normal.  As the operating system is working it will occasionally hit a glitch that produces an error in the log, but later in the log you will find where the problem was resolved.  The Event Log is never error free. If an error is repeatedly recorded then it is a problem. 
    You can also look at your Reliability History which might indicate a problem.  Go into Control Panel then System Security then Action Center then click on Maintenance and then choose View Relibility History. 
    If your remembered when the problem started, did you trying doing a System Restore to a date prior to the problem starting ? 
    You mentioned One Key Recovery.  Did the recovery process not correct the problem or did One Key Recovery not work at all ?
    Try booting the computer into Safe Mode and see if the problem is happening there. 
    Also try logging into the computer using another User account.  If no other accounts are available then create a new User account to try it.  If the other User account is problem free then suspect your original account has corruption. 
    On my Windows 7 system the sound event for connecting a device like a USB flash drive and disconnecting the flash drive sounds about the same.  Also the sound event for a device failing to connect will produce the same sound in my present sound scheme.  Try plugging in your keyboard and mouse several times to insure they have a good connection or even try plugging them into another USB port.
    Also try another mouse and keyboard if you have them available.  Since you are a gamer chances are the mouse and keyboard are well used and might be failing.

  • Dropped my ipod and now it makes a clicking sound and won't turn on at all. is it cheaper to get a new one or fix this one?

    i have tile floors and i dropped my ipod classic flat on its back while it was off. i tried turning it on after that and it now it makes a clicking sound and won't even turn on. all it shows is a dead ipod and told me to go to apple.com/support/ipod. i'm not sure how to fix it or if it's even fixable. or is it just cheaper to get a new one?

    If the phone will not power on try these three things:
    Connect it to your phone charger
    Connect it to your computer and open up iTunes
    Perform a hard reset (Hold down the sleep/wake (top) button at the same time as the home (circle) button for 45 seconds. When the apple appears on the screen let go of both buttons.

  • My ipod classic has started making a mewing sound and all it does is scroll through the songs.  It will not play except when connected to my computer.  I tried resyncing and that did not work. How do I fix this problem?

    My ipod classic has started making a mewling sound and all it does is scroll through the songs.  It does not play on my Bose sound dock or through earbuds.  It will play when connected to the computer...but that makes it hard to take it on a walk with me   I thought it might be a synching problem so tried that--still doesn't work.  How do I fix this problem with out restoring it to the factory setting?  I do not want to lose all my music content as some of it I cannot replace easily.  Please help with suggestions and advice. Thanks.  Karen in GA

    Have you recharge your iPod for at least 2 hours, preferably till the Full charge Battery symbol comes ON.?

  • My mac book pro is on, but the power light indicator is not on, the battery charging light is not on, and the computer is making a whirring sound, what is wrong

    My mac book pro is working, but my power light is off, the battery power light is not on and my battery power symbol is a black x. My computer is making a whirring sound sort of like it does when  loading a CD. I had a hard time getting the computer to turn on, used the command, option, P and R buttons to turn in on. I have tried restart, but I still get the whirring sound. What is wrong and what do I do?

    Didn't do an SMC reset. But in attempting to find out about what that was I found some things to try first. Also, when I went to system preferences - hardware, I couldn't find anything regarding power and battery info. Finally, I unplugged the computer for several seconds, then shut it down, removed the battery, put the battery back in. Then I turned on the computer, plugged in the power cord. Problem solved- no whirring sound, battery charging light is on.
    Thanks for getting me in the right direction.

  • EMac won't start and 3 beep sound and light flash

    My eMac suddenly got problem these days.
    Last night, eMac can boot and login. Suddenly, the monitor cant display property. Then, i enforced to power off. Later, trying restart it. eMac cannot start up and breeze 3 beep sound and flash power light.
    I checked support forum. It claimed that "3 beep - no good banks". Actually, i dont understand what it is. What i can i do??

    KY18,
    Welcome to the Apple Discussions!
    The three beeps mentioned in Power On Self-Test Beep Definition means that during the startup test of RAM, the Mac detected that there are DIMMs physically in one or both sockets, but that neither DIMM is functioning electrically.
    It's unlikely but possible that one RAM DIMM may have suddenly failed catastropicaly, far more unlikey if you have two DIMMs installed. A more plausible scenario, considering your mention of display problems, would be if the eMac were plugged directly into a wall outlet, or into a low-cost surge protector whose MOV hardware had degraded and failed (the status LEDs on low-end surge protectors are essentially worthless). If there was a power surge while you were using the computer, that could have blown out the RAM (and potentially damaged other hardware as well). Surch brownouts or surges are usually evident in the effect on room lights, clocks, and other elctronic devices plugged into the power outlets.
    As a longshot, you can try pulling the RAM DIMMs and then reseating them in the slots, making certain that the thumb clips holding the DIMMs have snapped fully into place after reseating them. Check the RAM installation instructions at eMac - Do-It-Yourself.

  • I am trying to log onto a Mac Mini I haven't used in awhile and I forgot the password. I am trying to reset the password with my apple ID but the computer keeps saying the Apple ID and the password are incorrect whenever I know they are.

    I am trying to log onto a Mac Mini I haven't used in awhile and I forgot the password. I am trying to reset the password with my apple ID but the computer keeps saying the Apple ID and the password are incorrect whenever I know they are, as I am using the exact same ID right now.
    I have switched my password in the past, so my theory is my mac mini thinks that my password has not changed and it will not update because The Wi-Fi password has also changed so it cannot connect to any servers...Does that sound like I am on the right track?
    Is there a way to update my Wi-Fi password  (saved into the computer) without logging on?

    If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
    Otherwise, boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
    When the OS X Utilities screen appears, select
    Utilities ▹ Terminal
    from the menu bar.
    In the Terminal window, type this:
    resetpassword
    That's one word with no spaces. Then press return. A Reset Password window opens.
    Select your boot volume if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
    Select
     ▹ Restart
    from the menu bar.
    You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.

    I tried to start my k450e, but there was no beep sound and no signal on my monitor. How can I fix this? I don't know what is the problem.... and should I visit the local warranty service providers??

    Welcome to the Lenovo Community !
    I am assuming that the computer is showing some signs of life such as the fan spinning or lights illuminated.  If there isn't then check your power source.  Try plugging the computer in a different wall socket.
    If the problem still continues and you are not comfortable working inside your computer or your warranty is still active then I would recommend you contact Lenovo Support for additional assistance in getting your computer repaired or visit a local area Authorized Lenovo Repair Center.

    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.

  • Seagate FreeAgent Go is making a clicking sound and the light is rapidly blinking. My Macbook is no longer recognizing it. Is there any way to fix it or recover my files? The SeaAgent is less than a month old!

    Seagate FreeAgent Go is making a clicking sound and the light is rapidly blinking. My Macbook is no longer recognizing it. Is there any way to pull all the songs I have saved on it? The SeaAgent is less than a month old!
    Does anyone know how to fix this issue?
    Or at least recover the lost data?
    Thanks!

    How to fix: the drive is in warranty, so contact Seagate for a replacement.
    How to recover your data: Do you have backups? (If not, you really, really, should.)
    You can try downloading Data Rescue, which will run in trial mode and let you know if the data is recoverable. (You can then choose to purchase the full version if it works for you.) A clicking drive, though, is usually (though not always) a sign that the drive cannot be recovered.
