Hardware test using Disc 1

Hi,
I am just wondering if running the hardware test using disc 1 will detect failure of one or both fans. Thank you for all response.
Bob

Hi Michael,
Thank's for your reply. So if say one fan is dead and the other one is working fine, there will be an error message?

hardware test using an external optical device (iMac) on macbook pro 9 years old via firewire. What to do? and how to do it?
I thiunk the graphic card is defective and need to run hwt

You don't.
Need a internal optical drive and the Hardware Test on disks is old and outdated anyway.
Your machine has lasted a long time, congratulations, they usually only last about 4-5 years.
They get clogged up with dust and overheat, kills the video card, there is nothing you can do as it's hardware damage over time.

Apple Hardware Test : Use original Tiger Instal disc, or new Leopard disc?

Hi,
I'm STILL trouble shooting my slow iMac. I figure this may point me in the general right direction.
My question is if my computer came with Tiger, and Leopard is now installed, which startup disc should I use?
thanks

Hi:
Try the OS X 10.5 DVD (boot while holding down the "D" key). I have, frankly, never tried to run an "old" hardware test on a "new" computer, but nothing should be harmed by trying.
Incidentally, slow is usually software-related not hardware-related.

Imac 24 aluminum - apple hardware test using wireless keyboard

The manual that came with my imac describes the steps to run the apple hardware test as follows:
1. disconnect all external devices, except keyboard and mouse
2. restart mac holding the 'd' key
The apple hardware chooser should appear next.
When I do these steps it goes right to my desktop every time. I am running a mac wireless keyboard and mac mighty mouse.
Anyone have an idea how I can get the Apple Hardware Test up?
Thanks.

Hi,
It can take a few minutes for the AHT to appear after booting, D key, etc:
http://support.apple.com/kb/HT1509
Try shutting down your iMac, reboot and THEN do the AHT.
Are you able to boot from the restore disk?
To check the hard disk:
Open Disk Utility, in the Utilities folder in the Applications folder.
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the Menu Bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click the Verify button. If DU reports errors, click Repair. When it's finished, from the Menu Bar, select Utilities/Startup Disk. In the Startup Disk window select MacintoshHD 10.x.x and click Restart.

Apple Hardware Test - no disc available

Hello!
In the last time, i have some problems (USB Hardware fails, doesn´t get recognised; Vent is going up to 5000 Upm when temp of cpu is at 56°C,...), with my mac mini 2.1, so i wanted to run the Apple Hardware Test. But unfortunately, i can´t find my 10.5 discs, which came with the mini and on my Snow Leopard Disc, there is no AHT available. I can´t find a Download (except for much older hardware) and do not want to go to a dealer and pay money for a diagnosis, which can made by myself with the right software.
Can anyone help me with this issue?
Thanks for any help!

Apple Hardware Test OR Disc Utility

Hello -
My HD is running VERY slowly and continually crashing programmes.
I ran the Apple Hardware Test and my HD passed with flying colours!
But... is this different from Disc Utility?
Are they on the same iBook Software DVD?
Please help - many thanks.

Look in the utilities folder under applications, it should be there by default since its installed with every copy of OSX. Then repair permissions, that can help speed things up. Also how much space is left on your hard disk. As it gets full it may slow down a bit as it searches the drive for your data. Also disk utility will be under the utilities menu or the Apple menu (not sure which at this moment) when you are running from the OSX install disc. Also how much RAM do you have, if you have limited RAM and try to run a lot of programs at the same time you might experience slow downs.

Apple Hardware Test using Leopard

One of my MacBok Pro USB ports has failed 24 hours after installing Leopard. It may be a coincidence because it was working fine for a while after the install. I would like to run the AHT but how? With Tiger, you inserted the install disk, rebooted, held down the 'D' key and there it was but this does not work with the Leopard disk. Can anyone help?
Thanks.

I believe somewhere I read that it is on the Leopard installation disk. You hold down a specific key (I don't remember which one unfortunately) when you insert the disk.
Good luck!

Apple Hardware Test problems

Hi All. I have a very weird problem here, as I can't get the Apple Hardware Test to start on my late 2008, 2.66 MBP15 inch model# MC026LL/A (released early 2009 as a quiet upgrade from 2.53). Here's the story:
I opened up my machine as usual one morning, and the optical drive made a very weird noise I never heard before. So I decided to run the Apple Hardware Test (AHT) to see if anything was amiss. Well, I inserted the second install disk, held down the "d" key, and restarted the machine. It began to boot into the hardware test, but just after the AHT screen appears the computer just shut down. This happens every time I try to run the AHT.
I went to an Apple Store while I was on holiday in Brisbane (they don't have one here in Adelaide), and the genius said it was likely a bad optical drive. Well, I returned to Adelaide last week and had the local Apple Authorized store replace the optical drive. Tried to run AHT once again, and the same problem persists. So the original problem wasn't with the optical drive.
I thought maybe I accidentally used the startup disks for my wife's late 2008 15inch, 2.4, MBP (the one actually released in late 2008). I've looked around for the other sets of disks and can't find them. So here's what I'm asking help for: can someone who owns a 15inch MBP 2.66 15-inch (released in early 2009, model# MC026LL/A ) please tell me what the part # is for their set of install disks? It is written on the plastic sleeves of the install disks. And, could this person please tell which version of AHT is written on the disk itself? The set I have (which I think might be my wife's) has AHT version 3A158.
Might this be the problem, or should my computer still be able to run the hardware test using my wife's disks? I know they are both technically late-2008 15inch unibody MBPs, but I think my 2.66 (again, quietly updated and released in early 2009) might require a different AHT version, which would explain my inability to run the test. If not, what might be causing my computer to not run the AHT? I tried reinstalling OS X to no avail.
Thanks for all of your help!

I think I share your skepticism--if your Mac was shipped with the later version of the OS, you should not have been able to do a clean install with discs of an earlier version. It looks like some machines originally shipped with OS X v. 10.5.5 and others with OS X v. 10.5.6. I don't remember just when 10.5.6 came out.
Your two machines are likely very similar in build, and maybe similar enough for the OS to install. It may be that the AHT is specifically designed for the hardware in each machine, and that would be a bit different.
As someone else said in another thread, there ought to be a tutorial on how to keep track of the original install discs since they are always getting lost. Maybe a secure note in the keychain or something like that.
Out of curiosity, does the AHT work on your wife's machine? If not, there could be a problem with the install disc itself, and if so, you might be able to get a free replacement under warranty.
Good luck!

Apple Logo would not display and Hardware test problem?

HI all, sorry i am new to posting here, so apologize if my answer to the below is in this forum but i could not find it. What it is:
My mac mini when I started it up today, was not displaying the apple logo, it was just showing its white screen and it just would not move from it. I tried doing an apple hardware test by re-starting holding the button D while re-starting nothing happen. I had to disconnect all external items such as my external HD and ipod and then it became back to normal.
1st question is, why did this happen and how?
2nd question is, how come my apple hardware test does not work?
I have tried apple hardware test using the install disc for a mac pro which has leopard on it, for my mini as i don't have the install for my mini any more. But even then I should still be able to use the apple hardware test without the discs though shouldn't i?
Please note though my HD has been replaced twice before by apple. Can anyone give some input?
Also my mac is an intel based back got its late 2006 model.
I have also run disk utility and it has found nothing wrong at all with my mac.
Thanks in advance for your replies.

If AppleCare gives you a Tiger Install Disc for your system, accept it, since it's the way to perform the AHT on your machine (also, it's free!).
About the Leopard disc, I don't know which OS you're running, since you changed your profile info from 10.5.6 to 10.4.10. Are you using Tiger Or Leopard?
If you're running Leopard, you'll need a Retail Leopard Install Disc (the one you can pick up from a store shelf) to do an Archive and Install. Your machine was made in 2006, before the release of Leopard, so there's no Leopard machine specific disc for your model.
Archive and Install is the way to reinstall the Operative System without loosing your files and settings.
Also, if you ever need to repair your startup volume with Disk Utility, you'll need to boot from the install DVD, and you can only do it with the install disc of the OS you're currently running. You can't use a previous version OS install disc, as it could have nasty consequences on the directory structure integrity.
If you want an "el cheapo" Leopard Retail Disc, you can search for it on the web. Also, when Snow Leopard hits the street, some retailers will probably sell out the previous version inventory.
Good Luck.

Apple Hardware Test, What is the Extended Test?

Hi. Using the Apple Hardware Test under disc 2 of the iMac's (late 2009) there's a checkbox for an extended test but it takes significantly longer compared to around 3 minutes only with a normal test. What does the extended test that the normal test have? Does it test more parts in the iMac?
Is there a third-party that's better than Apple Hardware Test that can test every bit of hardware in the iMac including it's power supply, internal battery charge, transistors, capacitors (if there are capacitors that are about to burst or are not delivering the proper voltage or current), if every pixek in the LCD is good, if the speakers are not torn, etc.
Gbu.

The extended AHT does a much more extensive set of tests on your RAM.
An alternative memory tester is Memtest which is a terminal command with Rember being a GUI layer for memtest.
There's also the diglloyd tools memorytester but it is not free.
AHT does video testing but I am not sure how extensive it is. And I'm pretty sure no utility exists to do component-level validation. Does such stuff like that exist for any piece of electronic equipment (TVs, radios)? That's what volt meters are for and possible test points on the pc boards.
I should add there are utilities like iStat Menus which are capable of displaying temperatures, volts, amps, watts of all many components of the hardware. But they just display the info, they aren't testing the stuff. It's up to the person looking at that info to decide if something is too hot, drawing too much current, etc.

Ran Apple Hardware Test from USB Install Drive on new MBA, Got this error

Last week I got the fully loaded 2010 MBA 13" (2.13ghz/4gb/256gb).
It's just perfect, I have no problems with it.
On a whim, I ran the quick Apple Hardware Test using the included USB install drive (took just a few minutes) and it came up with this:
Alert! Apple Hardware Test has detected an error.

Any ideas on what that means? Hopefully it's a false positive. I'm running the extended test right now, which will take more than an hour. Will report back.
Anyone seeing anything from the hardware test?

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.

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:

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

Can I run hardware test and repair a disk with Leopard using 10.3 DVD

Hi,
I'm trying to decide whether to partition and clone Leopard to my external or partition and install Tiger on the external.
My iMac came with 10.3.6 install and hardware test DVD's and they (Comp USA) gave me a Tiger drop-in DVD. I upgraded to Leopard through a family pack DVD (when I told my friend I would by one of the install's I thought I would get a DVD, but you only get an install license, oh well). By the way, Leopard runs great in my rev A iMac G5.
I'm trying to figure out which os to use on the external as a safe-boot incase something happens. If I clone Leopard onto a partition for backup/boot, can I still use the Disc Repair (not permissions) and Hardware Test from the 10.3 or Tiger DVD's to maintain that permission should something bad happen? The way I see it, i'll be able to repair permissions on both the main and external drives using Leopard's disc utility, but I'm not sure if I can repair a Leopard disk or do Hardware Test on that disc using an earlier version of OSX install/Hardware Test DVD's.
Will earlier versions of OSX repair a Leopard disk and be able run Hardware Test?
Thanks for the help,
LowBb

Yes, that seems to be the case, but I didn't do good enough research when he asked if I wanted a license for Leopard. For some reason, I had it in my mind that a Family pack came with multi DVD's for people. Maybe that's why he sold me a license so cheap. I thought I was getting a bargin, you get what you pay for.
So, I have the hardware test DVD's that came with the iMac and the Tiger drop-in is just an upgrade with no Hardware Test, you are correct.
But: (let me make sure I have this right) I should not use the 10.3 DVD's or the Tiger drop-in to repair a disc (not permissions) on a hard drive running Leopard. Is this what you are saying? I kind of thought this would be the case. If it is, I'm going to install MY stuff that I have the DVD's for on the external as an emergency boot disc.
