Apple hardware test - how long?

I have tried to run the Apple hardware test with my iBook G4. The reason for this test is that my ethernet port has stopped working.
I have tried all online tips I can find with no result. The only things I haven´t tried is the hardware test and a complete reinstall of the OS X
(in case the ethernet problem is software related)
The hardware test works great until the test of the logic board. 33 seconds after pushing the start button, the fan speeds up for a second or two
and then slows down and stops. The progress bar stops and there are no sounds from the ibook.
It looks like the test have frozen, although it could be working veeeery slowly.
After 37 hours I was feed up so I pushed the stop button. No reaction.
Other two - button combinations doesn´t work. The only thing that stops the test is holding down the power button.
The iBook boots nicely from the hard disc and from the installation CD.
So my question is:
How long should the hardware test normally take?
Any other ideas?
Timmy

The Apple Hardware Test does not actually check the Ethernet port directly. It will, however, check the logic board that the Ethernet port is build-in to. Usually the longest part of the test is RAM. If you're not even getting as far as the RAM tests, then there could be something wrong with your hardware that the AHT can't overcome. But, in any case, it should never take more than an about an hour to run.
Perhaps it's time to consider getting an AirPort card for the iBook and using wireless Internet at home?

  • HT201257 Apple hardware test how to start it?

    I haven't optical drive. So how can I start the Apple hardware test without optical drive? I have a 15 inch mid 2010 macbook pro.
    I have the problem sometimes my display under osx or under windows 7 professional stay black I can't do anything and can only restart the laptop via powerbutton.

  • HT201257 Holding down "D" no longer starts Apple Hardware Test!  Any idea what's happened and how I fix it?  Or do I need to go to the Genius Bar?  MacBook Pro with Lion Preinstalled.

    I have a MacBook Pro with Lion Preinstalled, so AHT was present on the hard disc and worked when the product was new.  One of the first things I did from new was run AHT and it worked fine.  But now it doesn't start - instead the machine (eventually) boots into normal OS X.
    Holding down "D" no longer starts Apple Hardware Test!  Any idea what's happened and how I fix it?  Or do I need to go to the Genius Bar? 
    Software  Mac OS X Lion 10.7.3 (11D50b), if it makes any difference.
    Any ideas?

    Thanks.  However, even with an internet connection that doesn't work for me - the machine just (after an extended delay) boots normally.  It doesn't download.
    Option-D works for an Internet-based AHT.  However that only works with an internet connection.  It doesn't seem to download it and install it - it needs internet every time.
    Any idea how my local copy of AHT disappeared?  I haven't repartitioned the drive or knowingly deleted anything.  And how do I reinstate it (because if you need AHT your hardware problems may preclude internet access!)?

  • How to launch Apple Hardware Test from a USB optical drive?

    Hi all!
    First off, and before you guys starting proposing solutions I can't implement, I don't, repeat DON'T have a Firewire optical drive, nor am I going to buy one: I recently had to buy a USB LG optical drive to compensate for my SuperDrive going AWOL on me. I used said drive to reinstall OSX about a month ago, so this LG drive works just fine, thank you.
    The thing is, I'd like to conduct an Apple Hardware Test, and I know you have to boot from OSX CD n°1 (in my case) to do that. Alas, since I can't boot from the CD in my SuperDrive by keeping the D key down, all I have is this LG thingy, and I wonder how I can conduct my hardware test with a USB optical drive.
    I'll sum it up for you:
    1) My SuperDrive isn't working, stopped working about the same time I installed this EFIng (guffaw, guffaw) Security Update 2009-001;
    2) I don't have a Firewire optical drive;
    3) All I have is a USB optical drive and MacOS X CDs.
    4) Booting with the OSX CD in my USB optical drive and keeping D, C or alt keys didn't help.
    I read in another forum that you could somehow copy the content of the OSX CD on a flash drive, then boot from the flash drive and conduct an AHT, but I'm not sure how it can be done.

    Hi!
    Looks like we posted at exactly the same time, Glynn! LOL
    Anyway, I did just what you said, drag'n'drop and all. The problem is, when I boot from the USB hard drive, it's exactly as if I were booting from the CD: first I'm asked to choose a language, then the install screen appears, and I can either reinstall on my startup disk from the USB hard drive (that's kinda cool, but I don't think I leave in on my USB hard drive, which can only content 40Gb, because I've almost 25Gb worth of data to retransfer soon...
    So, in a nutshell, I couldn't find Apple Hardware Test anywhere. I even explored the CD content, but there are so many files...
    What's my best option now? Could AppleJack help me here? Can I install AHT on my startup disk and boot on it using a special set of keys?
    Almost time to go to work. A 5 minute walk, though...

  • How to obtain apple hardware test for MacBook Pro (15-inch, Mid 2009), how to obtain apple hardware test for MacBook Pro (15-inch, Mid 2009)

    I no longer have the software disk (OS10.5) that came with my MBP in July 2009.  I only have the $10 Snow Leopard disk from Apple, which does NOT seem to contain any Apple Hardware Test (AHT).  I have tried starting while holding d or option keys to no avail.  Does neither my laptop nor OS 10.6 install disk have AHT?  If not, can the appropriate AHT be obtained?  My wife has an older MacBook & her original 10.5 install disk, but it will not launch AHT in my MBP.  Any suggestions?
    Thanx

    I like the advice to contact Apple and simplky pay for a new AHT.  I did that, giving them the serial number of my MBP and indicating it was a June 2009 model, 2.66 gHz Core 2.  However .....
    I received yet another Apple FedEx shipmet with yet another different Mac OS X Leopard install DVD; this makes three in all!! Just as with the 1st DVD, these two will NOT mount on my desktop, are NOT seen by Disk Utility (or by Drive Genius) and cannot boot my MBP laptop in either of 4 different modes: (1) start-up with "d" (2) start-up with "option d" (3) start-up with "option" (4) start-up with "c".  Apparently none of the disks I received have Apple Hardware Test on them, although that is what I paid for in early December.  It may be that the last two disks really do have Mac OS X Leopard on them, but because I am now running OS 10.7.5 (purchased from App store with no AHT), the disks cannot be seen by my laptop.
              The two most recent incorrect DVDs I received have the following part numbers:
                        SRF2Z691-6037-A [indicated on packing slip 10.5 Retail-International]
                        SRF2Z679-6341-A (indicated on packing slip 10.5.6 Retail (PCrly 09) In]
              I happen to have MacTracker app 7.2.1.  It indicates that my laptop is a MacBookPro 5,3 model A1286 EMC2325 and requires Apple Hardware Test 3A171.  Apple never sent me the correct AHT.
              I suspect that Apple's cost to ship 3 incorrect DVDs by 1- or 2-day FedEx vastly exceeds the $17.44 price I paid for a working version of AHT for my computer, but have yet to receive.  

  • 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.

  • How do I run Extended Apple Hardware Test imac 21.5 mid-2010 mavericks

    How do I run Extended Apple Hardware Test imac 21.5 mid-2010 mavericks?  I have tried to start my computer holding down the "D" key but my iMac simply just restarts as normal.
    I have checked the list of iMacs that can be upgraded to do an internet Extended Apple Hardware Test and I do not have one of those computers.
    I cannot find any solution as yet.
    I do not have the start up disks or the usb disks.

    You can't run the hardware test without the installation discs.
    Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity

  • Interpreting Apple Hardware Test Codes...How?

    Is there a chart or document that will allow me to decode the errors that are produced by the Apple Hardware Test software?
    I'll provide the two errors I've seen, but they don't happen all the time. I'd like to know what these mean, but I'd really like to know how I can decode these and future errors myself.
    4MHD/2/40000002:0x7ee50490
    I'm assuming this one is a hard drive error, but which one? Internal? External USB Drive? How do I tell?
    4YDC/2/40000002:0x7eea4890
    I'm not sure what this one is.

    First of all, thanks for all your and everyone else's help on this!
    I had some corruption on my internal hard drive which I was finally able to fix using a combination of tools (Diskwarrior and Speedtools) and a reformat and reload of the OS. I was still having problems, but they did not appear to be disk related. I started wondering if there might be some hardware issues causing the issues that may have led to the disk corruption previously and be causing some more current issues. I had installed Mac OS on an external drive and had been booting from that to run some of the various tools and I was still having problems. Anyway, as I've been unplugging one device at a time and doing testing, it seems that my system has become much more stable since I have left the one external drive with Mac OS on it unplugged.
    At this point, I'm guessing my problem is either a failing but intermittent internal hard drive (since it had corruption to begin with), or something about the external drive that my system doesn't like (that made the system unstable even after cleaning up the internal drive). Recent problems could be either or a combination of both.
    Anyway, I think this narrows it down pretty good, so I'm just leaving the suspect external unplugged and waiting to see if I have more disk related problems.
    Thanks again.

  • MacMini 2010 4,1 how to run Apple Hardware Test from  /System/Library/CoreServices/.diagnostics folder

    I have a 2010 Mac Mini4,1 with SnowLeapard and plan to upgrade to Mavericks, but can't run Apple Hardware Test from my applications disk 2 that came with the machine.  For some reason the Mac can read it and kicks it our after about a minute.  Seems to be able to reado other disks, so this one may be corrupted. I found info on this community that says that the AHT is on the hard disk and I found it here /System/Library/CoreServices/.diagnostics using terminal.  When open that folder using terminal it open a window with that folders contents.  My problem is I can execute the only unix executable in that  folder.  It responds with "No application knows how to open /System/Library/CoreServices/.diagnostics/diags.efi"
    Can someone help me out here or if there is downloadable somewhere on line that I can get?

    My 2010 4,1 Mac Mini still has the HW Test on the Internal HD after updating it to Lion, Mountain Lion and Mavericks.
    see > Using Apple Hardware Test
    Additionally if your using a wireless keyboard and it is not invoking the Hardware Test using the D key immediately after the chine, then you may need to use a USB keyboard. Adding that any Apple, PC or generic Logitech USB keyboard should work for invoking the startup commands. 

  • How to run Apple Hardware Test on Mac Pro with ML preinstalled?

    I have Mac Pro 5.1 (2012) which came with Mountain Lion preinstalled. It didn't have install DVDs. How do I run AHD? Restarting with D, or command+D, or option+D didn't work. It would just restart the OS. And Mac Pro didn't support Internet AHD eather.

    Thank you for your reply, Carolyn.
    I read this article. None of those applied to my case:
    my Mac Pro came before 2013 and it doesn't have Apple Diagnostics  built into it,
    it doesn't have Apple Hardware Test built into it,
    and my Mac Pro came with Mountain Lion preinstalled and it did not have system software disc or USB flash drive.
    Restarting while holding down the D key simply doesn't work it just reboot back to the desktop.

  • How do I use Apple Hardware Test on a Mid 2010 macbook pro?

    This MacBook is now running Mavericks 10.9.1
    This makes it so I can't update the firmware to use Apple Hardware Test within OS X internet recovery as discussed in this article:
    http://support.apple.com/kb/ht4904
    Holding down "D" at boot does nothing
    Holding down Option + D gives me Apple Hardware Test that can't be run because the firmware isn't updated and can't be updated because the update can only be applied to systems running Mac OS X 10.7.2

    You need the origional grey disk 2 that came with the mac when new.  It contains the AHT and applications.  You can call Apple and order the disks.

  • How do I run Apple Hardware Test on a 2012 MacBook Air with 10.8.4?

    Hello everyone,
    I am trying to run Apple Hardware Test on a mid-2012 MacBook Air with 10.8.4 installed. Whenever I restart and hold the letter D my computer goes into internet recovery mode and asks me to connect to Wifi... Please help, thanks!

    Using Apple Hardware Test on computers with OS X 10.7 or later
    Mac NoteBook and Desktop computers shipping with OS X 10.7 or later have a partition on the hard drive or flash storage that contains AHT. To start AHT on these computers please follow these instructions:
    Press the power button to turn on your computer.
    Press and hold the D key before the gray startup screen appears.
    It takes a minute or so for AHT to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
    When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.
    The AHT console appears. You can choose which sort of test or tests to perform:
    To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
    To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
    Note: Your test results will appear in the window in the bottom-right of the console.To exit AHT, click Restart or Shut Down at the bottom of the window.
    Some Macintosh computers that shipped with OS X Lion and later 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.  An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature. Internet-based AHT functions the same as AHT on the hard drive or flash storage outlined above.
    The Mac NoteBook and Desktop computers listed in Computers that can be upgraded to use OS X Internet Recovery will require a firmware in order to support the Internet version of AHT. Without this update you may see the behavior discussed in this article.

  • How to start Apple Hardware Test under OS X Lion

    Since I made the upgrade to OS X Lion I cannot start Apple Hardware Test with the old method that works under Snow Leopard.
    Under OS X 10.6.8 I used to keep D key pressed until a picture appeared in the middle of the screen. With Lion it doesn't work, even under Wi-Fi internet connection.
    Any suggestions?

  • How to burn Apple Hardware Test with 10.7 bought on the App store

    Hi Community,
    My friend has a MacPro with 10.7 on it. He upgraded his OS by buying it on the App store.
    Now he has a weird screen at start up
    We would like to run Apple Hardware Test on the install DVD but as mentioned he bought it from the App store.
    The only file we get is an installer (4.2 GB) but it is not a start up disk.
    Has anyone an idea of what could be done ?
    Thanks in advance for your help.
    Denis

    Apple Hardware Test can be invoked on Lion installations by holding D while starting from the internal HD. If that does not work try Option D as that will attempt to load an Internet version of AHT.
    I do not know of a way to burn AHT alone to DVD, but the disc that originally shipped with his Mac Pro will have AHT on it. Booting from that disc while holding the D key will load the disc's version.
