Fast blinking light! What does it mean?

The other day I shut down my computer. (Intel iMac matte screen, 10.4.11) Later, when I pushed the restart button, I failed to get a bong & the sleep light started blinking rapidly & bright. For a number of times I held down the restart button to get it to shut down, & then pressed it again to restart...same blinking light. (I've never seen this behavior before) I managed to finally get it to restart by double clicking on the restart button, but I don't even know why I tried that.
Anyone know what's up?
Bob

Hi Bob
That sounds like a ram problem!

Perhaps one of your modules has dislodged and need to be reseated, or is failing.
1. Try reinstalling-reseating both modules, firmly pushing on each one with both thumbs then close the ejector clips.
2. Then if it still acts funny, try installing one module at a time.

  • HT4528 My Iphone 4s is plugged in charging after it has fully died. Instead of the apple appearing and staying constant on the screen...the apple is blinking. What does this mean and how do I get the phone to charge/turn back on.

    - Try:
    iOS: Not responding or does not turn on
    - Next try letting the battery fully drain. After charging for a least an hour try again
    - Last, make an appointment at the Genius Bar of an Apple store, it appears you have a hardware problem.

  • My Power Mac G4 booted from an OS 9.1 install CD, and then froze up.  Now I turn the machine on, beeps 3 times, power button blinks 3 times.  What does this mean?

    I tried to install Mac OS 9.1.  I turned the computer on, heard the bong noise (although with some static), and inserted the OS 9.1 installation CD.  It started to boot, but froze up.  I rebooted the machine, and the same thing happened.  One more reboot, and i get 3 beeps and the power button is blinking.  What does this mean?

    Hi, it indicates a RAM problem, (or Logic Board around the RAM).
    The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
    If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
    1 beep  = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
    5 beeps = processor is not usable
    In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
    Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.

  • What is this code mean, ( 14 slow blinking lights and 5 fast blinking lights) mean

    need to know what this means please, 14 slow blinking lights and 5 fast blinking lights) mean

    thank you thank you for taking an interest. this is so frustrating.
    i only have apple keyboard, mighty mouse, and 20 inch cinema display connected. this morning took out memory and tried to boot up with individual pairs in the first bank. first the (2)256, the (2) 1g, and then the other (2) 1g modules. everytime I get the weird fuzzy wheel under the logo after a while, black screen flashes, then grey apple logo fuzzy screen then black forever.
    I ran tiger updates this morn. still will only boot to safe mode. then tried to run leopard disk to install it
    will not boot from leopard disk.
    tried safe boot, then doulble click install leopard, restart, then the saga repeats with the pixely red square around the wheel.
    these are fresh drives with only what came on instll disk loaded.
    thanks again for taking an interest.
    i love this system(well at least i did). I want to install leopard on my powerbook too but am terrified to do so right now since it is working and I have work to do. Can't afford to have no computer to do my work on...self employment is great?!
    This is making me crazy. I anxiously await your words of wisdom.

  • A family member set up my time capsule, promises that it is set up correctly but the light on the capsule isn't green, it is yellow, what does this mean?

    A family member set up my time capsule and sayy it's workign correcly but the light on it isn't green, it is yellow...what does this mean?

    If the Time Capsule is operating normally, the light will be green.
    If the amber light is blinking, something is not adjusted correctly, or there may be an update available for the Time Capsule.
    Do you have the device that was used to set up and configure the Time Capsule there?  Is this a Mac?  If yes, we need to know what operating sysem it is using.
    If you are not sure, click the Apple icon in the upper left corner of the screen and then click About This Mac. Post back with the OS X Version number that you see there.

  • What does it mean (and how do I fix) my light is solid amber?

    I plugged my Time Capsule in, but the light stays amber - what does this mean and how can I fix it?

    Normally on start up, the Time Capsule should flash green for a second, then display solid amber for 15-20 seconds and then...if the settings are correct....the light will turn to green. If there is a problem at this point,the amber light will normally blink slowly.
    If the light stays solid amber, this indicates that the Time Capsule has "locked up" and may have possibly experienced an internal component failure.
    Power down the Time Capsule for at least 15 minutes
    Hold in the reset button and keep holding the reset button in for another 10 seconds as you plug the power back in to the Time Capsule
    Release the reset button and see if Time Capsule will go through the normal start up sequence
    If you get a slow blinking amber light after approximately 30 seconds, you can now reconfigure the Time Capsule again using AirPort Utility
    If you try the factory default reset sequence above a few times and the light remains constant amber, I'm afraid that you'll need to take the Time Capsule to an Apple store to let them have a look.

  • What does it mean when there is a small red light next to my ear piece?

    There is a small circular red light lit up near my ear piece, I've never seen it lit up before and I haven't had my phone wet except for a few drops on the screen that were wiped away shortly after....
    What does this mean? I'm freaking out!

    It usually means that you may have upgraded the version of OS X to a version with which these apps are incompatible.

    HI, my tall time capsule is flashing orange. What does that mean? And how do i correct it to be green?

    Click the Finder icon on the dock at the lower left of your Mac's screen, then open Applications > Utilities > AirPort Utility
    Click directly on the Time Capsule picture
    If you see an Update button, click it
    Otherwise, click on the small amber icon and a message will appear to tell you why the amber light is flashing

    When I first plug in my power cord it lights up green and then after a few seconds changes to red.  What does this mean and how do I fix it?

    Apple systems in MBP have self-maintaining charging systems.  If the battery is less than 95%, the charger light turns orange when plugged it.  It will charge to 100% and stay green then will hold on charging until the battery drops to 95% again.
