My macbook air wont boot up. Just beeps every 5 seconds and a white light flashes on front of keyboard

That normally indicates an issue with system memory. The startup sequence can't complete the boot due to a memory issue. Take it in for service.

  • So i dropped my iphone 4 in class and the screen is cracked. it wont turn on so i went home and connected it into my itunes and the phone just keeps beeping like every ten seconds and the phone lights up just a little. What does this all mean?

    It means you should take it to the Genius Bar. You will no doubt need to buy an out of warranty replacement.

  • P35 NEO-2 FR won't boot. One beep every few seconds.

    Hello, I hope someone can help me
    Out of the nothing my computer crashed. There was a blue screen, but only for a split second, so I couldn’t get any information from that. After I tried to turn it back on I only got a black screen.
    Messages from my PC:
    One beep every few seconds. -- Means: DRAM refresh failure.
    The LEDs on the board have the combination red-red-green-green. -- Means: Decompressing BIOS Image to RAM for fast booting.
    Obviously I tried another RAM module. But it didn’t help. I don’t know what I should do, because I can’t even get to the BIOS. The screen just stays black.
    PS: I didn’t OC or try to flash a new Bios version.
    My system:
    P35 NEO-2 FR, BIOS v. 1.8, S/N: 601-7345-100B0805092463
    Intel Q9300
    G.Skill 2 GB DDR2 PC2-6400 CL5-5-5-15 (also tried brand new Corsair XMS2 DDR2 800 MHz CL5-5-5-18)

    Okay, please have a look at this document:
    http://www.ami.com/support/doc/AMIBIOS8_Checkpoint_and_Beep_Code_List_PUB.pdf
    As you can see, there are two main routines going on after you hit the power-on button:
    1. Bootblock Initialization
    __ and __
    2. POST Code
    Your problem description ...
    Quote
    The LEDs on the board have the combination red-red-green-green. -- Means: Decompressing BIOS Image to RAM for fast booting.
    ... indicates that your system halts in the first of the two main routines I just mentioned. To be more precise, it hangs at Bootblock Initialization Checkpoint D5, which is defined as follows:
    Quote
    Bootblock code is copied from ROM to lower system memory and control is given to it. BIOS now executes out of RAM. Copies compressed boot block code to memory in right segments. Copies BIOS from ROM to RAM for faster access. Performs main BIOS checksum and updates recovery status accordingly.
    In the last two phases of this checkpoint:
    Quote
    Copies BIOS from ROM to RAM for faster access. Performs main BIOS checksum and updates recovery status accordingly.
    The actual BIOS Code is copied into RAM and checked for integrity. When BIOS corruption is detected (=wrong BIOS checksum), the system will automatically jump into BIOS Recovery Mode (which is a sub-routine of the Bootblock Initialization routine).
    Now, this brings us to the actual meaning of the beep(s) you hear:
    Quote
    One beep every few seconds. -- Means: DRAM refresh failure.
    The BIOS Recovery mode (which is not part of the actual P.O.S.T. Routine, but a sub-routine of the Bootblick Intialization Routine) has its own set of Beep Code definitions which are described on page 15 of the document I linked you to:
    Quote
    Boot Block Beep Codes
    Number of Beeps -- Description
    1 -- No media present. (Insert diskette in floppy drive A:)
    2 -- ‘AMIBOOT.ROM’ file not found in root directory of diskette in A:
    3 -- Insert next diskette if multiple diskettes are used for recovery
    4 -- Flash Programming successful
    5 -- File read error
    7 -- No Flash EPROM detected
    10 -- Flash Erase error
    11 -- Flash Program error
    12 --‘AMIBOOT.ROM’ file size error
    13 -- BIOS ROM image mismatch (file layout does not match image present in flash device)
    Consequently, the meaning of that single beep, that repeats every few settings is not "DRAM refresh failure" (this would be its meaning in the P.O.S.T. Routine, but we are looking at the Recovery Routine), but it actually means:
    Quote
    1 -- No media present. (Insert diskette in floppy drive A:)
    What you have to do is this:
    1. Hook up an internal (!!) floppy drive to your mainboard
    2. Prepare an AMI BIOS Recovery disk:
    --> Download the latest BIOS Archive for your board from the product site
    --> Extract the actual BIOS File and rename it to AMIBOOT.ROM
    --> Copy the renamed BIOS File to an empty & formated floppy disk
    3. Put the disk that contains the AMIBOOT.ROM file into the internal floppy drive that you connected to the mainboard.
    4. Pray that the system finds the disk, reads the file on it and performs a recovery flash

  • My macbook air wont boot up past the loading screen. UPDATE

    My 2008 macbook air will turn on, and then go to the apple screen with the loading wheel, but after a few minutes of loading it just shuts down...
    Here is an update of the problem after i messed around with it for a bit.
    I start up the macbook while holding Command+s
    Then it brings up the prompt.
    I then type: /sbin/fsck -fy
    It then outputs a message saying:
    disk0s2: I/0 error.
    Invalid sibling link
    (4, 42746)
    **The volume macintosh HD could not be repaired.
    /dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8
    After that, i type in: /sbin/mount -uw /
    Then I type: exit
    It runs the logout scripts and then immedietly boots up fine, like the computer has no problem.
    It works fine like this, but i dont want to have to do those steps every time I want to use my macbook...
    Any help on how to fix this?

    I have a similar problem. Not sure you're on here (since the post is really old) but did you manage to work it out? How?
    My thread:
    https://discussions.apple.com/message/19007548#19007548
    My Imac froze earlier today as I was dragging an image from safari into indesig and when it froze the weirdest pattern overlaid the screen. It looked just like the opacity pattern from photoshop with grey and white squares. I turned the computer off using the power button and unplugged everything.
    Now when I try to start it these weird lines appear on my start up screen (see link)...
    http://meijerladdaruppgrejer.wordpress.com/2012/07/24/oops/
    as you can see the apple and the wheel appears as normal...
    ... then it moves to a normal looking white screen (perhaps a bit greener than usual) and around 30 seconds later freezes at the blue screen.
    I've tried the cmd + alt + p + r several times but it won't help.
    If i press alt during start up I can see and choose my hard drive but just end up at the blue screen again.
    Can I try starting it up in safe mode or something?

  • My macbook air wont boot up

    I get the grey screen with the spinning timmer animation. 

    See if you can boot into safe mode, if not youll need to reinstall your OS, how old is your AIR? Yours might have come with a boot OS memstick, of if running Mountain Lion you can erase and reinstall via net connection.
    Mac OS X: Starting up in Safe Mode
    Learn how to start up in Safe Mode.
    To start up into Safe Mode (to Safe Boot), do this:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    During startup in Mac OS X v10.4 through Mac OS X v10.6.8, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically. During startup in Mac OS X v10.2 through v10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
    To leave Safe Mode, restart the computer normally, without holding any keys during startup.

  • My macbook air wont boot.

    Hello everyone.
    I dont know what is going on with my mba. I just cant turn it on. No sound no fan,nothing. The light charger is green,sometimes is red. This is the third time. Its  only happen when i shut down my mba without macsafe. I dont know why. Tried smc reset but nothing different. I even shake my mac but still nothing. I dont know if it something wrong with the logic board.
    Thanks for the help.

    Do not shake your Mac under any circumstances.
    only happen when i shut down my mba without macsafe
    What exactly is, "macsafe" ??
    And which OS X is installed?

  • Why does my Macbook Air make a single buzz/beep?

    Why does my Macbook Air make a single buzz/beep every time I open it or turn it on? It doesn't happen after again after the initial buzz. If I open it after it has been sleeping, it starts up and then there is a buzz. This has only happened since I downloaded iOS Maverick.

    Beeps on startup:
    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images.
    5 beeps = processor is not usable

  • A beeping sound, along with a little white light blinking on/off on my MacBook Pro?

    My MacBook Pro is making a loud beeping sound along with a little white light blinking on and off at the bottom of the keyboard. None of the keys are working so I do not have the ability to shut it down. Any idea how to stop the beeping sound?

  • MacBook Pro won't boot - stays on black screen and beeps every few seconds

    Hi,
    My MacBook Pro has been having issues - when powered on wont boot past the white screen and more recently will just stay on black screen and beeps every 5 seconds. I had someone look at it and it seems apparently the motherboard is the problem
    and either needs fixing or replacing. As I am traveling in Nicaragua the closest apple store is in Managua (capital). Would I be able to get the motherboard looked at and replaced if need be at this apple store? Also, does anyone know the approximate price for the motherboard to be replaced? Up until a few days ago the laptop was still turning on and working every now and then but now stays on black screen and beeps.
    Any advice would be very helpful!
    Thanks

    Welcome to Apple Support Communities
    It means that your Mac's memory is damaged > http://support.apple.com/kb/HT2538?viewlocale=en_US&locale=en_US
    First, replace the memory modules. You can buy more memory at OWC or Crucial. It can also be replace by a reseller.
    If it doesn't work, the RAM slots are damaged, so your logic board has to be replaced. It costs more than a half of the price of your MacBook

  • My MacBook Air wont turn on. HELP!

    My MacBook Air wont turn on, I bought this past September (as a birthday gift for myself) and this Sunday I was using it perfectly, then at night it didn't turn on. I tried several times to turn it on and it did once, I thought "Yes finally" but two minutes later it turned off and never to turn on again. I have taken care of my mac book so much, that I really dont know whats wrong. I bought on I trip I did to the US and I live in Honduras, we don't have an Apple store here not even a Genius bar for me to go and see whats the problem, I thought this machines were for life, like I literally cried so bad because I had to work SO hard to buy this computer and now its just not working.. why? I dont know. If theres any tricks to making this turning back ON please let me know.
    Thanks APPLE...

    okay, since you are in Honduras, I'll share what my Genius told me when he reset the SMC on my 11 inch mid-2013 Mac Air yesterday.  He took it in back of the Apple store, came back in about five minutes with everything working. I asked him if there was anything I had done to cause the problem, he said no, except it might be better to actually "shutdown" the computer from the Apple pull-down menu when you aren't going to use the machine for more than a couple of hours (e.g., overnight).  If the instructions in Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support didn't work, As for self-repair, he said this is what you would have to do (but he also said, you really don't want to do this yourself): you have to remove the bottom of the Mac Air (under the keyboard), and disconnect the battery. Then, with the battery disconnected, you plug in the power cord attach it to the Air, and then turn on the computer from the keyboard on/off switch while powered only by the power supply. That should reset the SMC.  Then shut down the system from the Apple menu (not the keyboard button/switch), reinstall the battery, replace the bottom/cover, and see if it works.  Just remember that fiddling inside the back of a Mac can be dangerous to the Mac and your warranty!  Good luck

    Your boot drive is damaged in some way. If you have an original installation disc, you can boot from that and run Disk Utility. From DU you can select your internal hard drive ("Macintosh HD" is the name Apple puts on it - you may have renamed yours) and select "Verify Disk". If errors come up, try "Repair Disk". If it repairs, then you should be able to restart and boot from it. If it doesn't show up or won't repair, your drive is probably hosed.
