Hardware Test

I have a late 2008 Macbook Pro (silver keys..if that matters)..and I had my itunes on, then I closed the computer lid to make my computer go to sleep, and put my computer back in my case..I was gone for about less than an hour. When I returned I opened my computer and I realized it was off. I turned it back on and it took a little longer to start up than normal and as it started a Hardware Test started.
Does anyone know why this started?..and it was on for only 17 mins and 45 seconds but it didn't move and was frozen, I tried to stop the testing but that didn't work so I had to press the power button and then it started normal and I went to look on my help for the hardware. I went into another test in my hard drive and it was verifying it and then it completely froze and i could not force a quit nothing was working.. my friend didn't know how to help me so he flipped my computer over and took the battery out! it's working pretty fine now but i was just curious what had happened so if anyone can please explain what happened.
thank you

I believe that the AHT is actually installed on some models of the MBP, and you can access it by holding down "D" as you boot up. Now why it booted to the hardware test after being off I can't say.
Were you in Disk Utility trying to verify the drive when it froze? If so, you might want to boot from your install disc and navigate to Disk Utility on it and then see if you can repair your startup disk. Repair it until there is nothing left to repair. I'm wondering if you might have some directory issues that are contributing to this problem.
It sounds like your friend may have reset the SMC:

I don't know if this is the entire story, but it's my 2¢ worth. Maybe someone else would have some further insights.
Good luck!

I want to run hardware test on my Power Mac G5 but it isn't working.

What I tried:
I have the original install disc 1 which came with the machine in the optical drive (which is the usual one). I printed the hardware test guide which is on the disc, disconnected everything but mouse, keyboard and monitor. I tried to boot, pressing the Alt/Option key, but the "system picker" or boot menu won't show up. What happens is what somebody described as for "old world" macs: my system boots with no finder window open and without the white screen and apple logo (which usually shows up during startup).
I also tried something I found in a user manual pdf for Power Mac G5 on the apple archives: Booting and press-holding C (btw it's strange that this manual says something different than the manual on the original disc). What happens here is that my machine is booting from the original disc but it boots in Installation mode. I looked at every drop-down-menu I could find there for several times but there is definitely no hardware test, since this is thought to install Mac OS 10.4.
I also tried the Intel-way and holding D during boot, but no surprise, it only booted the first drive (like it should on a pre-Intel).
But something about this all is very strange. Yesterday night I tried all these steps above and when I was close to fall asleep in front of my monitor it suddenly worked and I made it finally into the hardware test. If I remember correctly, I was holding down the C key, but as I said a was pretty dizzy and can be mistaken. I ran hardware test once enhanced and it stopped during ram, giving me an error code I wrote down. But since I made it into the test and was so tired, I thought "lets continue tomorrow" which was my epic fail for this year, I guess. Today I repeated every step, every way I tried but it just doesn't work; and I read sooo many forums and Q&A's.
By the way here is my error code which appeared after 49 minutes (to proof I didn't dream this):
"2MEM/1/4: DIMM3/J14"
Why do I want to do this?
Around the 1st of September this year my Power Mac G5 didn't boot anymore (the fan speeding issue). After reading a little online I came to the point that its either my Ram memory or its my graphics card or its Pram or NVram. I resetted Pram and NVram, I also replaced battery and then it booted again for one day but on the following day it didn't. I repeated every step but the battery replacement since it was a brand new one. It can only be Ram memory or my Graphics card (which is the standard one for this machine).
Since then my Power Mac was rarely in use, only two or three times in Firewire Target Mode to access some of the data. Yesterday I wanted to do this again; booting it in FT mode but I must have connected my keyboard too late during booting and my machine surprisingly booted just fine! I was so stoked about this! Then I wanted to find out why it didn't work for a while and started several steps. Ran maintanance scripts, repaired the system volume, checked for enough free space, checked my Ram and then I stumbled on the interwebs over the hardware test which is delivered on the original install disc 1 and I never heard about this before (strange enough). What followed is written above.
What do I have?
I have this:

Sorry for the German but I think you still get it. The PPC was delivered with 10.4 and I bought it used from a friend with his original Update disc to 10.5 and I updated to the max, 10.5.8. I have 2x 1TB drive (similar ones) together as a Raid0 and three partitions on it. (I know now that it doesnt make that much of a sense).
Yeah so I really want to find out why my machine didn't work for three months but since it is so old and I'm a student, it doesn't make any sense to me to go to an Apple store or similar to have it expensively serviced since there is no guarantee that these guys really help you (heard some stories about the local stores here).
Is there a way to re-access the hardware test and run it to the end?
As you might have noticed, I'm pretty desperate. I would soooooooo appreciate it!!
Best,
Erik

"2MEM/1/4: DIMM3/J14"
Replace the memory in the DIMM 3 slot.
If you are running Mac OS X 10.5 you can use this program to test your G5's memory:

It will subject your RAM to a more thorough test than Apple Hardware Test.

MBA (mid-2012) SSD failure after 8 weeks Hardware Test

Brand new MBA mid-2012 (8GB RAM, 128GB SSD running ML 10.8.0).
Failed to startup - Apple logo on grey screen appeared, then the spinning gear wheel, then a blank screen, then the spinning gear wheel, then a blank screen, repeating ad nauseum...
I reset PRAM and SMC - no change
I opened in Single User Mode to run fsck - no change, then in Verbose mode to see what messages appeared (flashing messages of appleid verification timeouts)
Disk Utility - no problems detected
DiskWarrior - no problems detected
Tech Tool Pro - (1) SMART check picked up 7 SSD failures/errors:
[Wear Levelling Count, Program Fail Count(total), Erase Fail Count (total), Power-off Retract Count, Media Wear Out Indicator, Total LBAs Written and Total LBAs Read all 7 FAILED], remainder of SMART tests passed, and SSD PASSED SMART check.
Then (2) Surface Scan checked all 236+million blocks, NO BAD BLOCKS identified/detected.
Very strange indeed!! - booted into Recovery Drive, verified and all ok, no problems starting from this partition! Problem lies on normal boot partition (of course...!)
Was able to boot from external ML HDD and was able to pull all files off Air (interestingly Carbon Copy Cloner reported one text file sitting on bad block and was unable to copy/clone)
Time to get serious: Spoke with Apple Tech here in Australia late on a Saturday pm (thanks Olin!)
Ran Apple Hardware Test in Extended mode [took me back to System 7 days with very old icon!!] - took around 1hr and reported error "4HDD/11/40000000 SATA(0,0)" so it looks like new MBA is heading back to Apple!
I am thinking about re-installing ML from the Recovery Drive in case I can get the MBA running again to make sure I have all my file backed up, but it looks like an 8 week old MBA is no more...
anyone else seen this in mew MBAs? would hate to think I am the only one! plenty of other discussions around this error on HDD machines, but haven't found anything for this error for a SSD.

I have a 15-inch, retina, 2.7 GHz, 16 GB RAM, 768 GB flash drive MacBook Pro notebook, running 10.8.2
I have noticed that if I run the extended hardware test while connected to the power supply I do not get the error 4HDD/11/40000000:SATA(0,0) but if I run the same test while on battery power I get that error.
Does the same happen to you?
Any idea of what the problem is?

Mac Pro 2.66 Quad - Hardware Test error

Hi all !
I am trying to help out someone in another state with their Mac Pro problem so bear with me ...
The machine is a MacPro 2009 I believe, 2.66GHz Quad. and it's having startup issues - at the moment it's NOT starting so I am told !
Before it went totally down someone was able to run the Apple Hardware Test on it and got an error code -
4SNS/1/40000000: TMA4- 128.000
Ive searched and found the 4SNS refers to a possible sensor problem, but the TMA part of the code is unknown ...
It is also showing 1 of the 4 red ram led lights so there looks like a ram issue as well, but Im just wondering if anyone can shed more light on the error above so I can try to pinpoint the problems closer ?
At the moment Im being told by the locals it might be the logic board which of course is quite expensive ...
Mitch

My rule of thumb when faced with multiple problems is to address any you can get your hands around, and the symptoms may change and clarify the other problem.
A RAM LED stuck on is a memory failure, and that is easy to fix -- remove or replace the failing module.
It is also possible the sensor complaint is about that module -- they have temp sensors on them.
If you are replacing modules in a 2009 or later, don't buy smaller than 8GB replacements, they are cheap enough now at about US$75 from

My Mac is doing strange things: delaying between users, mouse flickering and bouncing, gets stuck with rainbow wheel flickering. I ran the appel hardware test and it detected an error: 4MOT/4/40000003:HDD-1233 Does anybody know what that means? HELP!

My imac is doing strange things:
-delaying between users: when closing session it goes to blue, then takes a while to appear users signin box, and then wont recognize mouse command to enter until a couple of minutes later... then everything seems alright until....
-it gets stuck between things, the rainbow wheel appears and its just delays there forever....
-and every now and then the mouse starts flickering and bouncing wildly onscreen.
I ran the appel hardware test and it detected an error:
4MOT/4/40000003:HDD-1233
Does anybody know what that means? HELP!

WZZZ answered about where to get iStat. And do check the SMART status. If it is an overheating problem due to a fan or logic board problem, your hard drive is possibly cooking itself to death. If so it isn't a faulty hard drive even though the hard drive might fail. So assuming it's a temperature problem, even if you are able to repair things on the disk with software, that is working on symptoms, not causes. I could be wrong however.
RE: AppleCare: Your iMac came with one year of AppleCare (Apple's warranty program), but within the first year you can buy 2 more years. You have to extend by the one year anniversary of purchase of the computer. Your 10,1 is too old to still be in the first year, and since you asked what it was, I'm sure you don't have it. Bottom line meaning is that whatever this problem turns out to be, you'll have to pay for it. Unless there is something like this. It is for 2011 iMacs with certain Seagate drives. You can put in your serial number for fun, but it looks like yours is too old. Lastly, some people have had Apple help them anyway if it is just out of warranty, but many have not. Your machine is one of these. Type in 10,1 in the search box. Is there an Apple Store near you? Just b/c it's out of warranty doesn't mean you shouldn't have it looked at by Apple. But no one here can say at all what Apple will or will not do.
Hope you get it taken care of!

I want to run apple Hardware Test but can't find it on any CD's. I bought my iMac in 2009. I think it had 10.4 installed. It's not on my installation disk. Where can I find it?

I want to run Apple Hardware Text but can't find it on any CD's. I bought my iMac in 2009. It came with 10.4. Apple Hardware Test is not on the installation disk. Should I have it? Where can I find it? I"m now running 10.7.4.

The disc plainly state:
To use the AHT, hold down the D key as the computer starts up.
Works here. However, there was an issue with installing Lion that screwed this process up.
Mount disc 2, run this command in the Terminal app, OPTION-click & hold Finder's Dock icon, and select RELAUNCH:
defaults write com.apple.finder AppleShowAllFiles 1
That unhides all hidden files/folders.
Now, drill down to /"Applications Install\ Disc"/System/Library/CoreServices/ and drag the .diagnostics folder into your Lion boot volume's /System/Library/CoreServices/ folder. That might require you to authenticate to copy the folder into the CoreServices subfolder.
Run this command to hide the normally hidden files/folders and RELAUNCH the Finder again.
defaults write com.apple.finder AppleShowAllFiles 0
This should allow the machine to boot into AHT when restarting and holding down the D key.
If that doesn't do the trick, run this command in the Terminal app:
sudo chown -R root:wheel /System/Library/CoreServices/.diagnostics
At the Password: prompt, carefully type in your admin password, since nothing shows up on the screen, and hit the return key. Then, try another restart, holding down the D key.

Need to run a hardware test on MBP4,1, 17" OS 10.5.8 w/out disc?

I have a macbook pro with the following specs:
- 17inch macbook pro 4,1, 2. 5 GHz
- non-unibody (released sometime in 2008)
- OS 10.5.8
My battery recently expanded and 'exploded', so i bought a new one (from macsales.com) and replaced it. battery works fine.
I also upgraded my RAM: from 2GB to 6GB (1 x 2GB, 1 x 4GB).
I have two issues now:
1) I have a birdlike chirping sound that occurs randomly and not often. I had similar sounds prior to my battery expanding and going bust. However, now that I've bought a new battery, I have a concern that it might be something else in the hardware.
2) I would like to upgrade my OS to mavericks; but first, I understand that i have to upgrade to Snow Leopard (10.6) before upgrading to anything.
I would like to know the following:
a) I would like to run a hardware test to diagnose it and find out what the sounds are from and also a general check up before i actually upgrade OS.
However, I don't have my installation discs because I moved country and it was a long time ago.
How can i run a hardware test and check my laptop without a disc?
b) since i'm not in the US, how can i buy the Snow Leopard? is there an option for buying when outside of the US? I can't seem to find it.
thanx for your help

Can I run the hardware test when I have four different accounts on my mac 10.8.4, can I run the hardware test when I have four different accounts on my mac 10.8.4

Hi Noticed that the top of my mac is nearly too hot to touch. Did a search online and found out about the hardware test. Looked up online user manual for my mac (Processor 3.06 GHz Intel Core 2 Duo 10.8.4) and noted how to perform the test. However, when I keep my finger on the D button through start up it just brings me right to the screen where I have to sign in to my desktop account (there are four accounts on the desktop as it is a family mac). Am I doing something wrong.

Welcome to Apple Support Communities
First, you should know that it's normal that your iMac is hot at the top. Here are the fans, so it's normal that it's hotter than other parts. Before going further, download Temperature Monitor and tell us which temperatures it indicates > http://www.bresink.com/osx/TemperatureMonitor.html
If it gives dangerous temperatures, then you should run Apple Hardware Test. Looking at the processor the Mac has got, your Mac came with DVDs. Apple Hardware Test is in Mac OS X Install Disc, so insert it and hold the D key while your Mac is starting to start in Apple Hardware Test

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.

Separate Apple Hardware Test DVD for MacBook Pro original??

Hey Folks, I'm trying to verify whether or not the MacBook Pro came with the Apple Hardware Test as a separate DVD disk. The "MacBook Pro" Install disk references it but I can't seem to find the software on that DVD. Any guesses out there would be appreciated. I'm about to perform an upgrade for Tiger to Leopard and wnat to give my laptop the "hairy eyeball" before I begin.
Many Thanks,
Peter

Insert the DVD and start up the computer with the D key held down. The Hardware Test is on a separate area of the DVD and isn't normally accessible.

I have a latest 2.7 EFI update but i still don't have the ATH(Apple Hardware Test) software! why is that so? do we have it on mountain lion?

So as u know the question
ill tell u the steps to try them out(no harm will be caused to u or ur com)
During restart-up press the D button before the gray screen appears and hold it for about a minute until u see a 4 or 6 bit image of old mac icon appear and then it loads u go select any language and click hardware test full and then tell me if it DOES HAPPEN ON OS X 10.8(mountain lion).
Thnx apple and u guys!

To use Internet Apple Hardware Test, start up your Mac and hold down both the option and D keys on your keyboard.

Can't boot off Apple Hardware Test disk

Can anyone suggest why my laptop won't boot off of its Apple Hardware Test disk anymore? I have not tried it in years, but want to try now. I have the original, and a copy I made years ago, and neither will boot. I can select them at startup disks in that preference pane in OSX, but then it fails to find it, and boots into OSX. I can boot into OS9 on the hard drive. I was able to partially boot off of a different AHT disk from my 12" Albook G4, but it gave the message that I can't use that disk since it is not meant for the Tibook. One idea is that TechTool tells me that "macintosh startup file was absent", and the Help file states:
"The Startup file is intended for use by systems that do not have built-in ROM support for booting from HFS Extended volumes. The first eight extents of the Startup File are stored in the Volume Header. This makes them easy to locate and read into memory. This file contains information used by the computer’s ROM to determine what program will boot the computer. In almost every case, this will be configured to point to the preferred System."
But it does not tell me how to restore this Startup file.
-how can i get my startup file back?
-my computer boots fine off the hard drive, so is this file used only to boot off a CD?
-any ideas why i can't boot off my AHT CD?

Hi, t. (That alias of yours sure is a mouthful.) I think in your shoes I would pose the question to the tech support people at Micromat (TechTool's developer). It's their error message, after all, and they should be able to explain it to you in as much detail as you need. Perhaps they'll shed some light on the original problem in the process.

Error Message from hardware test

Hi,
I just recently bought a 1 gb PC2700 SODIMM 200 PIN DDR ram (EDGE TECH) and installed it in my 12"powerbook (1.5Ghz) to replace the original 256mb chip in there.
However, I got several application crashes and decided to run a hardware test and I got an error message for the ram:
2MEM/2/4:DIMM1/J31
Does any of you know what does it mean? So is the memory bad? WHat should I do? replace the ram with edge tech or it's the compability, edgetech just won't fit on powerbook? But in the description they said it can be used on powerbook though.
Please help!
Thank you!
Tom

I'm experiencing the same problem, it's really horrible! can anybody give me a clue? Thanks in advance

Blue screen of death with HDD Hardware Test error on iMac HELP!!

My iMac is not starting up. It just get the blue screen of death during startup. It is a 2.66 mghz duo with 2gb 800 ram. I was able to get the Hardware test to run and got an error of 4M0T/2/40000004: HDD-1560. I am assuming it is an error with the internal hard drive since I have nothing else hooked up to the mac other than the keyboard and mouse right now. Does this code mean my hard drive is completely shot? Any help would be appreciated.

4M0T/2/40000004: HDD-1560.
Either failing or failed
You can have Apple replace the drive at a nearby Apple store or an Apple certified repair shop.

Macbook dies after 2008-005 security update: even hardware test not working

My Macbook no longer boots after installing security update 2008-005. Behaves as if HD is dead, AND as if boots from SuperDrive are broken too.
Sequence of events:
1. 10.5.4, Software Update notifies me of update.
2. I permit it. Immediately requires a reboot.
3. Go away for several hours.
4. Upon return, I notice the Leopard outer-space background.
5. Spinning beachball when I move the mouse.
6. Go away for several minutes.
7. Return. No change. Power down computer.
OK ... by now, you may be saying that it might still have been updating and I shouldn't have interrupted it.
But since then, the machine behaves not only like the disk is dead, but I can't even get a hardware test to run from DVD.
So, to continue.
8. Start machine again. Apple boot sound. Nothing on screen.
9. After a while, flashing "folder" icon with question mark.
Since then I've attempted to boot in safe mode, verbose mode, FireWire target disk mode (against a 10.4.x box), boot from original install disk, boot into hardware test mode from original install disk. None of these things worked. I've reset the PRAM.
The only diagnostic activity of all of these that has produced any different feedback is the PRAM reset (which sounded the Apple boot sound a second time). Everything else does not work. If the HD was dead, I could understand that none of the attempts to boot into FireWire target disk mode, or to boot from DVD and then expect to see the HD mount in some way, would work. But since it doesn't even boot the hardware test from the DVD, I'm really baffled. Any ideas? Thanks.

Well, my solution was to buy DiskWarrior and copy what I could (which was a lot, thankfully) to a FireWire external disk, then reinstall. DiskWarrior reports S.M.A.R.T. status OK, so I've gone with a fresh partition in Disk Utility and successfully installed 10.4 from the original DVDs.
Have also run Apple Hardware Test and had no problems, so I've decided to trust the drive in the short term.
Unfortunately, now, 10.5 upgrade disks won't finish and guess what ... a partial install of 10.5 breaks the 10.4! So, the machine has a recognizable startup disk but justs sits in a loop rebooting itself, presumably as it hits some inter-10.4/10.5 state and gives up.
Next up I tried to restore my 10.5 from a wired ethernet connection to my Time Capsule. Having never once been able to browse my backups in Time Machine under 10.5, I was somewhat surprised to find that the 10.5 Installer was happy to let me try a restore from the Time Capsule. It crunched away until it was happy that I had enough space on my new partition, and then did what seemed a pretty instantaneous restore. The Macbook reboots and ... can't see the startup disk.
Maybe my disk really is on the way out.
