Computer just beeps when power button pressed

I put my mac to sleep after working on the iphoto arranging vacation pictures.  This morning when trying to reawaken the IMAC it just returned a series of beeps from inside the computer.  Unplugged and tried again but the same beeps occurred.  What is my next course of action?

Those tones usually mean a memory issue, where the memory is not passing the power on self test (POST). This Apple note details them for newer iMacs:  http://support.apple.com/kb/HT2538?viewlocale=en_US . Of interest:
1 tone, a 5-second pause, repeat No RAM installed
3 successive tones, a 5-second pause, 3 successive tones RAM does not pass data integrity check
You can try reseating the memory to see if that fixes it. This Apple note tells you how to do that: http://support.apple.com/kb/HT1423

  • Is there a way to automatically shut down laptop when power button pressed?

    Of all the things I am having to struggle through a learning curve on MacOS (converted from Windows), this might seem like a rather benign concern, but I'm going to ask anyway. . .
    I would like for my laptop to automatically go through a shutdown process when the power button is pressed - that is, bypass the dialog box that appears when hitting the power button that gives you the option to restart/shutdown, etc.
    I've looked in all of my system preferences without anything that controls the behavior of this button so I imagine there might be a terminal command or an app that might accomplish this?
    Thanks in advance for any help or advice.

    I'm trying to set up my MacOS to have the power button automatically go through the shutdown process as IF I had actually clicked on a confirmation box to shut down the computer.
    I don't know of any way of doing that... perhaps there's a 'haxie' out there that would generate a shutdown command when pressing the power button, but I don't know of one.
    Sorry,
    Clinton

  • Computer just beeps when it's turned on

    My computer screen went black: My screen goes black every time I turn it on I tried a bunch of things but it didn't work. I think the screen was just broken. It seemed to be coming on like normal, just without a screen.
    Then I really messed it up. I pulled out the battery and followed the instructions under there to pull out... motherboards? Bad idea. Then when I put it all back together, every time I turned it on it would just beep... a lot.
    I don't know if there's anything on the screen because the screen doesn't work.
    At this point, I think the computer is broken. But I'd like to be able to at least get the files off. Any ideas? Is there some way I can fix this and hook up a backup to it? Is it worth it to try to bring it in to a computer fixing store?
    Thanks!

    I suppose it's a memory trouble. Reseat memory sticks or get new memory and install them could solve the problem.

  • HT2173 iMac late2006 17". When power button pressed, white light comes on and stays on but nothing else happens?

    As stated: our Mac won't turn on other than the white light on the bottom right.
    Read through the support page which suggests taking the back off ( and use internal power switch) as in owners manual section 4, however it's not in there.  At the bottom there is a couple of screws and a couple of star head screws, I'm guessing I need to undo these and possibly pull from the bottom.  Don't want to break it,
    Thanks
    Mike

    A steady LED light generally indicates that the computer is on and the display is asleep.
    Before you get inpatient and start taking out screws or trying to open it up, which is not an easy task on that model.
    Reset the SMC, as per > Resetting the System Management Controller (SMC)
    1. Shut down the computer.
    2. Unplug the computer's power cord.
    3. Wait fifteen seconds.
    4. Attach the computer's power cord.
    5. Wait five seconds, then press the power button to turn on the computer.
    Then run the AHT, as per > Using Apple Hardware Test

  • Logoff/shut down/restart window does not appear when power button pressed

    For a couple months now my G4 Powerbook running 10.4.6 has not responded to pressing the power button. This also applies to the restart/logoff/shut down options from the Apple menu -- no response.
    I reloaded Tiger using the save personal preferences and settings and the malfunction is still there.
    Ideas? (I haven't called AppleCare yet.)
    TIA

    Assuming that you mean you did everything that Sherry
    and I offered up in our responses, then create
    another admin account, log into it, and see if the
    problem persists. Cryptic one-line responses aren't
    very helpful. If this suggestion doesn't make the
    problem disappear, then install the latest COMBO
    update (10.4.7 was released today), restart, launch
    Disk Utility, repair permissions, restart, and
    hopefully that'll fix things.
    I have another - "clean" - admin account and the problem persists there. And I downloaded the 10.4.7 update and the problem persists. If there isn't much to add, why go beyond, as you call it, a "cryptic one-line" response.
    Ended up calling AppleCare and will do a clean archive and re-install. Thanks for the suggestions.

  • When i click on my external hard drive the screen goes dark and a msg pops up saying i have to shut down my computer by holding the power button and then restart it. when i do that i get the same result every time. it worked perfectly last night..

    when i click on my external hard drive the screen goes dark and a msg pops up saying i have to shut down my computer by holding the power button and then restart it. when i do that i get the same result every time. it worked perfectly last night..

    These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Ifou don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
    In the Console window, select
              DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
    (not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
              View ▹ Show Log List
    from the menu bar.
    There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
    If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
    In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
    Please don’t post other kinds of diagnostic report.
    I know the report is long, maybe several hundred lines. Please post all of it anyway.

  • It all of a sudden stopped working and when I try to click on something my computer just beeps at me. I cant even exit imovie

    My imovie all of a sudden stopped working when I was in the middle of making a project and then all of a sudden when I tried to click on something my computer just beeped at me. I cant even exit out of the program! Or shut down my computer unless I quit imovie. Help?!?!

    What version of OS X and iMovie are you using?

  • When I shut down computer I get a clear grey screen telling me I have to shut computer of using the power button?

    Everytime I shut down my computer it gets a grey transperent screen over the desktop and it has a box in the middle that tells me I have to shut the computer off holding the power button until the computer quits.
    I had been trying to install a print/scan driver. Also during the course my Suitcase fusion app tells me it can't open the fusion fontvault at that location.
    I've been using suitcase for quite awhile now so I'm not sure wht it's acting up now?

    If the screen looks like this
    then it's a kernel panic.  Resolution starts here:
    OS X: About kernel panics
    The new print/scan driver is a likely suspect.
    good luck

  • I have reached out  to this community as my Iphone display gone black and got the solution to keep home and power button pressed. It worked but I would like to know why it went black

    I have reached out  to this community as my Iphone display gone black and got the solution to keep home and power button pressed. It worked but I would like to know
    1. Why it went black and is there a permanent fix for this
    2.Will the IOS gets automatically updated as I feel the IOS was 5 when I got the phone in 2012 december
    3.Do you suggest 7.1 for Iphone 4

    1. There is no way of knowing. These things happen.
    2. The iOS only gets updated when you want it to be.
    3. You should always update to the latest iOS your phone will support. Apple do not write the updates to make your experience worse.

  • How is when a button pressed a report will come to the same page !!!

    Hi all,
    I wonder that is it possible to bring a report to the page as a region but only when a button pressed in apex .When ı clicked the go button for example ı want to list a report in the same page.
    but I dont know how .If is this possible can you explain me please.I need help!
    Thanks!

    Create your report in a region as normal.
    Create a second region and in this region create an item eg p171_item.
    In the same region create 2 buttons
    Get Report and Reset (branching back to same page).
    Create 2 page processes (PLSQL) on submit after computations
    1. GET REPORT
    DECLARE
    v_item number;
    Begin
    select 1 into v_item from dual;
    :P171_ITEM := v_item;
    end;
    2.RESET
    DECLARE
    v_item number;
    Begin
    select 2 into v_item from dual;
    :P171_ITEM := v_item;
    end;
    Tie the processes to the buttons.
    On your report region put a condition
    PL_SQL RETURNING BOOLEAN
    IF :P171_ITEM = 1 THEN
    RETURN TRUE;
    ELSE
    RETURN FALSE;
    END IF;
    Now by pressing the buttons the report region is opened and closed.
    Now hide P171_ITEM.

  • My macbook air has a black sreen, I can hear the apple chime when power is pressed but is stuck on black screen

    My Macbook Air has black screen, I can hear the apple chime when power is pressed but is stuck on this black screen.
    Also had beeps, 3 beeps was able to stop doing command/alt...
    What is going on???

    3 Beeps on POST usually indicates a memory problem.
    You will need to take it in for service, as you can't even so much as re-seat the memory on an Air.

  • IMovie files (v6) corrupted after computer switched off at power button

    I had two iMovie files open when my computer froze. I had previously successfully dropped both of these files into the auto-play box in iDVD's Map View (so that I could avoid using "themes" in iDVD — a tip I read at this site). When the computer froze (with the screen appearing completely fragmented with multiple colours during a play back in DVD Player of a DVD I'd burned of this same project), I had to switch the computer off at the power button, and since this happened iDVD will not allow these same two iMovie files to be dropped into the auto-play box in iDVD map view. I then tried dropping older movies into the auto-play box, and I've also created a new smaller 'test' movie to drop into the auto-play box and  all worked OK. So it appears that the iMovie files that were 'open' at the time the computer had to be switched off are now corrupted. I can play them and edit them, but can't get them into iDVD the way I could before.
    Does anyone know if these files can be repaired (easily)?
    Would appreciate any help, thanks.
    Cheers,
    Lehla

  • Computer does not turn on, power LED goes off when power button is pressed

    My Pavilion 17-e078nr has stopped working, it will not power on. When you push the power button, the power LED next to where the plug is goes off and takes several minutes before it comes back on. I've tried removing the battery and get the same results and with the batter in and AC disconnected the power button does nothing. I've also tried the hard reset with no luck. As far as I know, nothing has happened to the computer since last time it worked. My two theories are either the AC power is bad, or there is a problem internal to the laptop. The AC power is providing the 19.5V, I measured it using a multi meter, I'm just not sure if it's providing the required wattage, or if the connection to the laptop is secure, it feels a little loose, but at the same time the LED comes on, so I know it's getting a connection. Only thing I can think to try is go to a store that sells this type of computer and see if I can use one of their power supplies to power my computer, and/or plug my supply into one of their computers. Don't know how willing any store would be to allow me to do that though. Any one have any additional thoughts or advise?

    Hi! I have the exact same problem... the LED on adapter, is very, very dim when connected.
    At first I tried connecting my macbook to my roommate's adapter and had the same problem. then tried taking out the battery, and still had the same problem. I did the same thing with my roommate's macbook, but hers did actually turn on! it operated without the battery. Figured out it was problem with mine.
    I kept on trying combinations battery, computer and adapter. turns our that my battery (which I thought at first was the problem) charges perfectly on my roommates mac, but wont charge on mine. her adapter won't work either on my computer. What I've been doing is charging my battery on her computer, then placing it on my mac, and it works. only thing that won't work is the adapter.
    Went to a mac store, and they told me that the problem was a small cable o wire that went from the Magsafe point into the mac and that the LED was very dim because no energy was being drawn from that spot because of this little wire being broken. they gave me the name of this wire... very technical stuff so, completely forgot cause I didn't have anything near to write on.
    I'd like to know if anyone has gone through this same ordeal, and had this wire replaced without any problems. When it comes to opening up my mac, I'm a bit skeptical, since warranty is expired and wouldn't want for a solution to become a bigger problem.

  • Macbook wont powerup, beeps repeatedly when power button is pressed and you need to hold the power button down to shut the beeping off. any thoughts?

    Have a 13" macbook. wont power up. upon hitting power button, the computer sounds 3 long beeps constantly until you hold the power button down for 5-10 seconds. any thoughts out there?

    Thanks guys, i just read a few articles regarding this. i pulled all the ram and tried swapping and reseating ram. it appears both chipsets are fine but one ram slot is bad. computer will boot with either chipset installed in the one good slot but neither chipset will boot in the other slot. bummer....
