HT1883 using the apple hardware test

Lion was downloaded from app store so I have not install disk and option D does not bring hardware test app as the support document suggests.

The AHT must be run from the original installer DVD that came with your computer:
How to run hardware diagnostics for an Intel Mac
Boot from your original OS X Installer Disc One that came with your computer.  After the chime press and hold down the "D" key until the diagnostic screen appears.  Run the extended tests for a minimum of two or three hours.  If any error messages appear note them down as you will need to report them to the service tech when you take the computer in for repair.
Some "common" error indicators:
SNS - sensor error
MEM - memory error
HDD - hard disk drive error
MOT - fan error

  • HT202731 What should I do next when using the apple hardware test and it will not complete. It always gets frozen when 56 seconds of testing has passed?

    MY MacBook pro will not boot up correctly. When switched on a grey screen appears and a flashing question mark box.after researching I have been able to try to complete an apple hardware test by holding the D key when switched on. Unfotunately this text will not complete. Every time I try and perform this text it sticks after 56 seconds of testing and does nothing rlse. Resulting in my having to force shut down.
    I know do not know what else I can do to try and solve my problem.
    Any help would be grately appreciated.
    Thanks.

    I would install a new HDD, format it and install the OSX.  Then I would connect the old HDD via USB and see if I can access the files that are on it.
    If no success and if the data is important, look for recovery software on the Internet.  Most have a trial that will tell you the possibilities for retrieving data but then you will have to pay for the software.
    The last option is employing a professional data retrieval service.  That will be expensive with no guarantee of results.
    Ciao.

    Have the Mini's Serial# handy & call Apple Care, they usually have original replacement Discs available.

  • Cannot start-up to the Apple Hardware Test — MacBook Pro & Lion

    Whenever I try holding the D key before and throughout all of the start-up process, it simply makes the grey screen appear for longer, and slow the whole process... but never beings the Apple Hardware Test.
    I'm following Apple's official instructions:
    To start up your computer in Apple Hardware Test:
    Press the power button to turn on your computer.
    Press and hold the D key before the gray startup screen appears. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature.
    Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT.
    Why doesn't it work?
    My MBP was shipped as follows:
    For Apple computers that shipped with Mac OS X v10.5.5 to 10.6.7, Apple Hardware Test is located on the Applications Install Disc 2 and should be included with your computer.
    But I have upgraded to Lion! Do I need the disk still? If so, why am I to lumber around a disk from a previous OS... good that I didn't throw it out!

    I'm trying to find the answer to a similiar question.  Here's my thread.

  • G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD

    We have a DP 1ghz Quicksilver PowerMac G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD that came with the machine.
    We were in the process of installing 10.4 Tiger before placing it for sale.
    The Mac was originally OSX Server 10.1 that we later converted to a worksation running 10.3 Panther.
    It has 1 GB of memory, 80GB hardrive, 250MB Zip Drive and a Radeon 7500 video card.
    Since this machine only has a CD-R drive and not a DVD-R, we installed Tiger using another Mac via Target Disk Mode. The installation process went well, but when I tried to reboot I got a Kernel Panic right after startup screen with the grey Apple logo.
    On some reboots we get to the blue startup screen, others it stops at the grey Apple logo, others a black box like the a Kernel Panic - but with no text. Twice it went directly into Open Firmware.
    We have done the following during our troubleshooting:
    - Reseat RAM, Video Card, Hard Drive, Zip & CD-R connections
    - Remove RAM 1 stick at a time and reboot
    - Replace RAM with RAM from another working Quicksilver
    - Replace Video Card with one from another working Quicksilver
    - Zap PRAM
    - Reset CUDA switch
    - Unplug the MAC and remove everything (RAM, Battery, etc) for 30 minutes and try to reboot
    - Tried booting from the Macintosh Server G4 Software Restore CD
    - Tried booting from Mac OS X Server CD
    - Tried booting from AppleCare Protection Plan CD with TechTool
    - Tried booting from Diskwarrior CD
    - Tried booting from an external FireWire drive with a disk image of Tiger OS Install
    - Tried booting with the hard drive disconnected
    The Mac WILL boot from the Apple Hardware Test CD and will pass ALL of the extended tests.

    Conventional wisdom says that any Mac that will not boot up from a System/Install CD OS 9 or an Install CD Mac OS X, has a Hardware problem.
    The diagnostic CD is a red herring because it uses a very primitive method of reading the CD, and so does not properly represent the machines general ability to read CDs.
    I would look at the CD drive cables, etc, and see if another drive gives different results.
    You have not mentioned using the Startup Manager (option key at Startup) to do any checking:

  • Is there a download for the Apple Hardware test 3A126?

    Is there a download for the Apple Hardware test 3A126? I get a gray screen for several minutes until start up, Tried holding down the "D" key but no test, there is a disc stuck in the superdrive so I can't use the install DVD.

    You can only run the Apple Hardware Test from the correct Disc that came with your system. see > Intel-based Macs: Using Apple Hardware Test
    Have you tried the following > The ultimate guide to ejecting a stuck disc

  • How can i get or download the apple hardware test for a macbook pro made in 2012 running Mavericks 10.9.3

    Does anyone know how can i get or download the apple hardware test for a macbook pro made in 2012 running Mavericks 10.9.3. Thanks.

    Sean and Andy -
    I have to agree with Andy here. I am having the same problem on a mid 2010 MBP (6,2). I have already read the AHT info provided by Sean's link, and they are less than helpful. I'm sure they will be helpful to those who find that they work, but they are confusing if this is not the case. For example, my MBP(6,2) came with ONE (not two) installation disks, so the instructions don't work for me. Another issue is the instructions confound the descriptions related to the MBP, the original (delivered) software (OS X version), and the current installed OS X upgrade software.
    So here's what does NOT work for me... 
         (A) I cannot install 'Disk 2', since I never received this with my original (new) purchase in mid 2010.
         (B) I have checked my firmware versions and they are all up to date, as per Apple's information.
         (C) As suggested in another thread, I looked for /Library/Core Services/.diagnostics and it was NOT present. I followed his instructions, downloaded the correct (I believe) dmg, and installed it. It is in the correct place, and I can see all the invisible files using Pathfinder.
         (D) When I re-start holding down the D key (immediately), it just goes through the normal boot routine; no evidence of AHT.
         (E.1) When I re-start holding down OPT-D, I get a spinning globe, and then it prompts me for a network (wi-fi) connection.
         (E.2) For some unknown reason, the prompt identifies between 2 and 5 of my --neighbors'--  routers, but does not show mine. (??!!)
         (E.3) The routers are listed alphabetically; however, my router SHOULD be at the top of the list by this criterion, but it is nowhere to be seen.
         (E.4) The 'internet recovery' process then allows me to enter a network name AND password. I do this, for my current wi-fi router, and the process rejects it as an incorrect login ID. It is NOT an incorrect login ID! 
    So, now asking Sean and Andy (or anyone else) for further suggestions... ???  As Andy suggested, many people ask questions here because they have -already- worked through the 'official' recommendations, and have found them to be inadequate.
    Any advice would be appreciated!  TIA.
    Ed

  • How do I run the Apple Hardware Test? Its not on my DVD and the Internet-connected version tells me my computer isn't supported!

    I have a mini - late 2010 2.4 ghz core 2 duo - that just started black-screen crashing and failing to wake from sleep. Up to a few dasy ago this was a really bulletproof machine! When trying to restart it afer a crash it sometimes emits three weak beeps (sometimes more).
    Apart from spontaneous motherboard failure (??) I can only guess that the RAM failed (an 8GB upgrade installed last fall). I pulled one 4GB RAM board and the mini booted again! But it still sometimes fails to wake from sleep, and sometimes give the three beeps. I've run REMBER (a memory test program) on one of the RAM boards and it passes the test. My next step is to test the second one -- but whether it passes or fails there seems to be something else going on.
    I'd love to try the Apple Hardware Test but:
    - pressing D on startup has no effect (even when starting up with the original install DVD)
    - pressing Option-D brings up an Internet-loading screen that brings up a Hardware Test screen then tells me my computer is not supported.
    Is the AHT simply unavailable for my model of Mac? And/or is there any way to test my hardware?

    The 2010 Mac Mini's came with a 2 DVD set, a Mac OS X Install DVD (22691-6657-A) and an Application DVD (22691-6658 -A). The Apple Hardware Test is on the Application DVD (22691-6658-A).

  • What Do I Put On the com.apple.Boot.Plist to Make Snow Boot to the Apple Hardware Test By Default?

    Hi. My main OS is 10.7.2 Lion but I had installed Snow 10.6.8 into a USB external drive. I will use Snow for apps that run well in it and for the Apple Hardware Test which is was my main reason why I installed Snow. Whenever I boot to this iMac's Snow DVD installers (disc 1 or disc 2) or to the one installed on the external USB drive and press D before the gray screen and 'ding', it doesn't want to go to the Apple Hardware Test. I want ot use AHT because I have no budget for similar apps like TechTool Pro.
    Why is pressing the D not working by the way?
    Is there a way to edit the Snow's com.apple.boot.plist to always boot to Apple Hardware Test (AHT)? What should I write in it. I'll be using Smultron to edit the plist instead of Terminal.
    Thank you in advance.
    Gbu.

    Put the AHT disc into the machine, restart, holding down the D key. AFAIK, you can't do the way you're envisioning.

  • Does the Apple Hardware test come with Snow Leopard?

    Does the Apple Hardware test come with my iMac 27" i7?
    If so, how is this activated and is it used as a periodic test or only when a problem develops?
    Thanks

    The Hardware Test will be on the Install DVD(s) that comes with your iMac. With the correct DVD inserted, (re)start the iMac while pressing & holding the "D" key to start into the HT. Run it anytime you want to check the hardware.

  • HT201257 Can I reinstall the Apple Hardware Test?

    After an OS reinstall, with a Macintosh HD erase, I've lost the ability to run the Apple Hardware Test directly from my drive.
    Now when I try to run it, it only does so from Internet Recovery Mode, which does not sit right by me, once it used to do so without requiring an internet connection and no official Apple article, specifically, warns you that any OS reinstall process can lead to this situation (at least none that I have discovered...)
    Is there any way I can get back that feature, which I presume would be installed in a Recovery partition?

    I was actually responding to your statement "I've lost the ability to run the Apple Hardware Test directly from my drive." and provided the link (see the Use Apple Hardware Test section) so that you can make sure you were performing the test correctly.
    Sorry, that the Article was of no help to you.

  • I can"t open the apple hardware test from the applecare support website

    i received the applecare training program for my birthday and while exploring the applecare service source website i found a image file of the apple hardware test (AHT) for each model along with a pdf of the service manual and a pdf of the AHT service codes. The problem i'm having is, i cant open the image of the AHT.

    After downloading that image, open it and it will show up mounted in your desktop. Then, open Disk Utility (in /Applications/Utilities), right-click your Apple Hardware Test image in the sidebar and burn it to a DVD. Finally, start your computer from the disc, holding the C key, so Apple Hardware Test should start, always that you have the correct version for your computer.
    You have Apple Hardware Test in the Applications disc that came with the computer. In that case, hold the D key while your computer is starting

  • The error code 4MOT/4/4000003:HDD-1393 has shown up from the apple hardware test. What should I do about this?

    My iMac has been running a little hot, it was suggested to run the Apple hardware test (AHT), as heat can cause problems witht he hard drive.
    The AHT revealed the error code 4MOT/4/4000003:HDD-1393 which I assume means a hard dtrive problem. But, what do I do. Is this a critical error or a minor fault. Everything is running as normal, but the machine is getting a little hotter than usual.

    This indicates problem with HD fan.
    Exact nature of the problem is only known to Apple.
    We have no way to interpret this error code.
    Keep a backup of your data.
    When you get a chance, take the Mac to the nearest Apple store to have it tested.
    Best.

  • Where do I find the apple hardware test

    Hi, I'm trying to find the apple hardware test. The article here: http://support.apple.com/kb/HT1509 does not help me - I've tried pressing the D key, but the test won't start. My version of Snow Leopard only has one DVD (10.6.3). I rebooted from the DVD and had a look in the Utility section, but could not find the AHT there either.  Any help would be greatly appreciated!
    Thanks in advance,
    Veronika
    Edit: OK, I see that it should be located on the original installation disks. However, I never had those - my Mac was once repaired under extended warranty (new harddrive), and they kindly upgraded me from Tiger to Leopard all those years ago. Any other ideas?

    Replacement disc(s) from Apple:  You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
