Apple Hardware Test & My Power Supply

I was wondering if the Apple Hardware Test does any check on the Power Supply.
I was planning on replacing mine on a Mac Pro (Early 2008). I have been having a constant freeze from wake issue, and the system refuses to power on from a cold start unless I let it rest unplugged for 24-48hrs.

Assuming it is/was getting good power and there aren't any problems with power itself, it sure sounds like SMC or logicboard or something.
Can't hurt to do an extended test.
The wake from sleep freeze type issue for 2008s early on was suppose to be fixed and resolved by an EFI firmware update last year (Apr/May time frame?).
I'd take it in.
Sometimes swapping parts is all that can be done to see if a component is at fault.

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.

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.

MacBook won't boot after trying to repair with Disk Utility. Cannot boot in Safe Mode. Just powers down after about 5 minutes. Apple Hardware Test says error 4SNS/1/40000001:IG0C-0.265 But I cannot find anything on the net about it. MacBook 4,1 Intel.

Hello Everyone,
I am in dire need of assistance I am hoping someone could provide. I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD.
I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc".
I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.
Any suggestions are welcome and appreciated.
Thank you for your time.

You've a couple of issues .... when Disk Utility tells you it can't repair a drive, if the error is a soft error, like an invalid tree or node, Disk Warrior (or TechTool Pro) can handle it. However, if Disk Warrior (or TechTool Pro) can't handle it, you can erase and write zero's to the hard drive and restore to it, or you can buy a new hard drive. Sometimes running SMART Utility can provide additional insight into the health of the hard drive.
THe 4SNS error is a sensor error. You could install iStat Pro to see if something is indeed getting too hot or remaining room temp or less. You may need to take it into an Apple shop so they can use their thermal diagnostics to test and isolate it further.

Won't Boot to Apple Hardware Test or accept Boot Commands

Hi All,
I would appreciate some help with this issue, I am trying to boot up to the Apple Hardware Test on my Install Disk 1 that shipped with my MacBook Pro 2.4GHz Model #A1226 ordered new with 4 gigs of memory (around Aug. 2007). I am currently running 10.5.6 and the install disk of course contains the Tiger OS. I have nothing plugging into my computer, other than the Power Adapter. I have the proper install disk inserted in the computer and am holding down the "d" key on my built in keyboard throughout startup, but it will not go to the AHT. It simply boots to the normal login screen for Leopard. In fact the only boot commands that I see any visible or audible confirmation that it has taken effect is the option key, taking me to selecting a Startup Manager and holding down the Power Button gives me a tone from the internal speaker after a few seconds.
Below are what I have tried with seemingly no effect:
"d"
"c"
"t"
Option-Command-"p"-"r" (no beeps)
Command-"v"
Command-"s"
Shift (not sure I should see or hear any confirmation, I don't have any login items set right now so I can't tell if it has any effect)
I have not tried an of the networked drive boot commands as I don't have any networked drives
The only way I have been able to boot from either the optical drive or another disk is either holding down the option key during boot up or selecting the drive from the startup manager in system preferences.
I can't seem to access the AHT an in any way. The reason I am trying to access it is because I have had a few weird intermittent problems that I can't put my finger on and would like to be able to rule hardware out.
I also just replaced my HD with a WD 320 gig drive after my original drive failed due to a physical error. I just restored my data, and all seems to be running well after a permissions repair and a disk repair while booted up on my install disk.
The intermittent problems I was talking about are very vague and rare so I is difficult to describe them other that just a hunch that something is still a bit off. One is the display, every once in a while, showing what looks like a massive bar code or UPC code on my screen. This is not like the bands with soft edges that seem to be a well documented issue with the early MBP but transparent lines of alternating width and brightness with hard edges. Again it looks just like a UPC code transposed on my screen. The other items are random freezing of the OS or the mouse and the fact that my keyboard does not respond to any but a few boot commands. Again all the things are either rare and intermittent or do not come up in daily use of my machine. But when taken together, seem to add up to the conclusion there is still some issue present (at least in my mind).
To recap my specific questions relate to not being able to run the Apple Hardware Test and many of the boot commands having no effect. If you can shed light on the other items mentioned, great!
Thank you!

At a guess, I would think this error code has to do with the video artifacts you are experiencing. You might try reseating all the cables to the display. If the position of the screen makes a difference, there may be damage to a cable, particularly where it goes through the hinge.
Apple is the keeper of the error codes. If you have access to an Apple Store, you could probably ask about this.
Don't know about the other intermittent problems. Does an external keyboard work? If so, there's likely a problem with the internal, maybe even again, a cable or connection.
You could also try creating a new use account and see if the keyboard and mouse problems persist. If not, there could be some sort of software corruption in your usual account. Ditto with the freezing.
Good luck!

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.

Files/Folders Sticking to Mouse Pointer - Not Releasing (Reset PRAM & Apple Hardware Test Fail to Run)

I've been having two issues with my Late 2008 MacBook Pro 15-inch - Running OS X 10.8.5 (Mountain Lion). Unable to Reset the PRAM and Run Apple Hardware Test (AHT).
On a random basis - File/Folder icons are Sticking to the Mouse Pointer - Not Releasing. I've done everything from trashing finder preferences, making sure Universal Access preferences are off, Restoring Defaults in the Energy Saver System Preferences, Resetting the System SMC. Another post mentioned that this is being caused by the Graphics Driver not working correctly - and mentioned to put the MBP to sleep, then wake it up, and the files/folders are no longer sticking to the mouse pointer. This works for me and released the sticking items in the Finder.
OK, Good this is a simple fix, BUT, what is really causing this issue, and how may it be fixed or repaired?
I also tried to Reset the PRAM and Run the Apple Hardware test (AHT), and these both fail to run on my MacBook Pro with OS X 10.8.5.
1) Resetting the PRAM:
Shut down the MBP, press the power button, and hold down at the same time <option><command>-P-R. The Reset PRAM process never starts up, but rather I receive the Padlock/Password Login which logs me into the Restore System Utilities. I'm unable to Reset the PRAM.
2) Apple Hardware Test (AHT):
Shut down the MBP, press the power button, and hold down the "D" key, the system boots up as normal and does not enter the AHT.
The File/Folder Finder sticking to the mouse pointer issue is very annoying. Does anyone have a solution to resolve this issue?
- Cheers

HI Barbara,
It sounds like the hard drive is failing or has failed. Boot from your Mac install disc and if you can run Disk Utility in case the startup disk needs repairs.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
If you cannot boot from your install disc, try booting in Safe Mode
What is Safe Mode

Cannot access Apple Hardware Test

I recently learned about the Apple Hardware Test, and decided to run it, just to see if it reported anything wrong.
I have a MBP from early 2008, 2.2 GHz Core 2 Duo, 15.4".
The built-in optical drive no longer reads DVD-type media. It will read CDs, but not DVDs of any kind. This has been verified by an Apple Genius; it needs to be replaced.
I have a Snow Leopard disc in an external drive, connected via USB. When the Mac is running, I see the Snow Leopard disc; I can access normally.
However, when I restart (or turn off, then on) the computer, and press and hold 'D' right away, nothing different happens; it boots into OS X just as it normally does. I have tried this a few times, both restarting and turning off then on, holding down the 'D' key right away.
Is the problem that the OS X disc is in an external drive? If this is the problem, then how is the AHT accessed on a MacBook Air?
Is the problem the Snow Leopard disc itself; does it not have the AHT on it to begin with? I can no longer locate the original 10.5 discs that came with my computer, but I believe I may be able to get ahold of a relative's later-version 10.5 discs.
Or is there some other problem or something else I'm doing wrong?

Hi again Justin,
Justin J. Rebbert wrote:
Well, as I mentioned in my original post, no, I do not have the original Leopard discs that came with my Mac. But as I also mentioned, I can probably get ahold of a set of Leopard discs that belong to a relative. One thing I did not mention, though, is that I'm pretty sure these Leopard OS X discs are retail (did not come with a computer). Do you know for sure whether or not regular Leopard discs have the AHT on them?
Yes, 100% certain. AHT comes only with the original discs that were supplied with your model MBP.
eww has suggested a link for you where they can be purchased for $33. However, with an internal optical drive that cannot read CDs/DVDs, your only options are:
1. Repair/replace the internal optical drive.
2. Purchase an external optical drive.
3. Create a partition in your external drive and then using either Carbon Copy Cloner or the Restore feature within Disk Utility, create a bootable image of the original OS DVD. When you start up from this bootable image it behaves in exactly the same way as if you started up from the OS DVD.
Justin J. Rebbert wrote:
I have no idea what you're talking about when you "like you did with Snow Leopard". I didn't have to make bootable images or use different partitions or anything like that at all, and I don't know what made you think that.
My apologies. In your original post you said:
I have a Snow Leopard disc in an external drive, connected via USB. When the Mac is running, I see the Snow Leopard disc; I can access normally.
The above made me conclude that the "external drive" was an external hard disk drive. Reading it again, I can see that you mean it's an external optical drive.
Now, I know that eww, in his reply to you stated the following:
I don't believe AHT can be run from an external drive. It requires all external devices to be disconnected except the AC adapter.
eww is very knowledgeable and well respected in these forums so I'm hesitant to disagree with him. I believe that one can carry out a AHT from an external optical drive but will test later today or tomorrow to make sure.
Justin J. Rebbert wrote:
Also, just FYI, from what I've read about accessing the AHT in other posts on these discussion forums, apparently all Macs (of a certain unknown vintage and later) have the AHT accessible from the hard drive, but this is only true if it's the original hard drive, which furthermore has never been reformatted. My MBP's hard drive is an upgraded (bigger and faster) replacement, so unfortunately, that's no longer an option.
No, it's not only true if it's the original hard drive.
It is, however, true if the OS on the replacement hard drive was installed using the original disks that came with that model Mac. The OS can the be upgraded to a later version but the fact that the original OS DVDs were used then, assuming the Mac model is of the vintage that allows it, a hidden small partition is created thus allowing the user to boot into AHT without needing the original discs to start from.

Using Apple Hardware Test?

Hi, I need some assistance.
I've got a MacBook Pro from 2011. That have some hardware, I'm sure. Please see this post. https://discussions.apple.com/thread/6029708
So I'm trying to use Apple Hardware Test. http://support.apple.com/kb/HT1509?viewlocale=en_US
But I can't make it work. And I've read the instruction for using the Apple Diagnostics test as well. http://support.apple.com/kb/HT5781?viewlocale=en_US
And it seems to me to be exact same approach.
Using Apple Hardware Test on computers with OS X 10.7 or later
1. Press the power button to turn on your computer.
2. Press and hold the D key before the gray startup screen appears.
3. 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...
To start Apple Diagnostics:
Turn off your computer if it is on by choosing Shut Down from the Apple () menu.
Press the power button to turn on your computer.
Immediately press and hold the D key until Apple Diagnostics begins.
If you previously selected a language for” the computer, a "Checking your Mac" screen will appear in that language.
Can anyone instruct help me? I've tried using 25 times enabling the AHT. But the little icon never shows. I just get the regular login screen after some time.

Sweet, OGELTHORPE
That worked! Apple own instructions are really not impressive. Haha. ****.

Can Apple Hardware Test disk work when a hard drive has no OS installed yet

I removed a bad original hard drive from a PowerBook G4 12" aluminum notebook. It made clicking sounds as it ran, and would not boot. I replaced it with a 320GB Western Digital HD. I also upgraded the original 512KB memory with 1GB.
Before removing the bad hard drive, I was able to boot just beyond the language selection dialog from a full installation CD (Mac OS X v10.2) while holding the "C" key during power on, but could not install it, of course, on the bad hard drive.
Now with new hard drive replacement in the PowerBook (formatted via fire wire from a MacBook Pro running Snow Leopard) and the upgraded memory, I ran a Disk Utility check via fire wire and found the new hard drive in the PowerBook to be in good working order and ready for an OS installation. However I can no longer boot the PowerBook G4 with the full installation CD in the customary manner, getting instead the flashing question mark over the finder folder icon.
I decided to see if there might be some other problem by using a PowerBook G4 Apple Hardware Test disk. Upon booting from the test disk, I get a message that declares the disk will not work with the PowerBook G4 machine.
What's up?
Message was edited by: techtoots

There's more to my original question than whats on the face of it. Please read more about this below. However, I will still wish to know if an AHT, say an original one if that's important, will do it's thing when no OS is installed.
Pretty sure that I'm NOT using either disk or sets of disks that came with this G4 PB. Included among what I do have are 6 grey disks:
__PB G4 Software Restore 1
__PB G4 Software Restore 2
__PB G4 Software Restore 3
__PB G4 Mac OS 9 Install v9.2.2
__PB G4 Mac OS X Install v10.1.4
__PB G4 Applications
And 2 Jaguar full install DVDs:
__Mac OS X v10.2 Install Disc 1
__Mac OS X v10.2 Install Disc 2
I was hoping to be able to find something useful among these disks - if not in a strait forward manner, them by some manner of hacking.
I know how to use my MacBook Pro create a disk image that will house any number of these DVDs. My thought is to create something that can be cloned to the PB G4 via fire wire. I just need to be sure how to daisy chain multiple DVDs in terminal mode, if more than one DVD is required in the cloning process.
I have placed an order for Leopard 10.5 - full installation DVD direct from Apple.
Once received, I will have 14 days to return it unopened. So, I want to be sure this PB G4 is operable before I break the seal on the Leopard package.
Therefore it's not so important that I clone everything from the original installation - just enough to see that the PB G4 boots and runs in Finder. If I can achieve that much, I will advance with Leopard 10.5 when it arrives.

Error 4PRC in Apple Hardware Test

Hello,
I have a 24" iMac (2.16GHz Core Duo, 1.5GB RAM) from late 2006. A few days ago, the display went black although the power stayed on. I turned it off, and it hasn't been able to boot since then. Whether I try to boot normally, in safe mode, or from the install DVD, the same thing happens: (1) happy startup sound with gray Apple logo; (2) that screen darkens and *sort of* a kernel panic message appears in the center. I say "sort of" because the kernel panic message's rectangle is in the right place and some of its text is readable, but partway down the rectangle it looks as though the drawing is offset somehow. Anyway, that's how this problem manifests itself: a kernel panic very early in the boot process.
Miraculously, the Apple Hardware Test starts up successfully from the install DVD. Both the normal test and the extended test give the same result: the RAM passes its tests, but when it reaches the CPU, the following error message appears, and the tests stop:
4PRC/1/40000003: Processor
That looks bad. I searched the web and various forums (including this one) and found very little information. An Apple document marked "Error Codes, Apple Hardware Test version 3A117" suggests that the appropriate action is to replace the processor.
I suspect that if I take the iMac to my local Mac repair specialists, they will offer to expensively replace the motherboard. I'm an old UNIX nerd and have tinkered with lots of machines other than Macs; can I simply replace my iMac's CPU myself?
Or is CPU replacement in fact unnecessary, when some other fix might work? Does anyone have specific advice about this error message?

In case it's helpful, here's a textual description of the panic from single user mode startup (which fails just as badly):

Apple Hardware Test Log?

I'm trying to sell my PowerMac G5, and the buyer wanted me to run Apple Hardware Test and email the log so they know it doesn't have any problems, but I'm not able to find a log anywhere. Is there any way that I'm able to meet this request?
Thanks in advance.

Hi, and a Warm Welcome to Apple Discussions and the Power Mac G5 Forum!
Well - can't say I've heard tell of an AHT log - perhaps the buyer can suggest where exactly this log might be located?
You could try taking a photo of the test output on the display, and emailing that.
The AHT runs in a basic OS from CD/DVD in order to minimise hardware resource usage and maximise test coverage - so the usual handy utilities are not available. The advice is invariably to write down any error messages. Some general AHT info here
http://www.thexlab.com/faqs/aht.html
Good Luck.

Problem apple hardware test

my macbook pro early 2011 i5 is too slow so i use onyx with no result so i make an Apple Hardware Test for check and i have a alert! a problem hardware with code:
4SNS/1/C0000008:TPCD--124

That sensor is reacting to the temperature at the CPU power bus. Make an appointment at an Apple store genius bar for a free evaluation. This is a hardware problem with no software solution.
Ciao.

Apple Hardware Test

I just upgraded the ram in my new 2011 iMac and I want to run Apple Hardware Test. Since Apple no longer supplied a DVD with this bootable app I was wondering how I can launch the App. I tried apple's online doc and held the "d" key down to try to boot it from the internet but eventually the OS just launches instead. I then read that you are suppose to pess Command + D, same thing its a gray screen for a while but then eventually launches OSX. I even tried a bootable DVD of Snow Lepard and its not compatable. Please help. Id like to be able to run the hardware test.
