Apple Hardware Test reports year as 4013 in diagnostics report? Why?

When I run AHT, I get "No Trouble Found". When I review the diagnostic report from About This Mac, I get "4013" as the year the test was run.
Does anyone have any insight?
For reference, I have a 15-inch, retina, 2.7 GHz, 16 GB RAM, 768 flash drive MacBook Pro notebook. I am running 10.8.2.
Thank you!
LukeD

Thanks, Sig.
The date is set properly to 2013. It only appears as 4013 in the diagnostics report for a Apple Hardware Test. Even the power-on self test appears as 2013.

Thanks - Even though I'm years out of warranty I got chat help from Apple (I said they should help me since the codes aren't published.) We covered three different questions, and although I didn't get a specific decoding of the error code, I got confirmation of what other comments here imply - it might have helped that I indicated I'd already been here - and useful links to how to do back ups, including to CD(s). (I don't have a lot of data on this computer yet)
Now I need to figure out how to decide how hot-to-the-touch is "too hot" for the metal frame at the top of the iMac to decide whether I'm getting adequate fan performance or insufficient. While chatting I initially reported it was cool at the bottom and warm at the top. Apple hadn't asked, but their response prompted me to feel it again, and I'd say the top was hot, not warm - I updated but Apple didn't comment further except to conclude after addressing the other questions that I should take it in for further assessment - don't really want to bother with that.

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.

Apple Hardware Test (AHT) Hard Drive Full Read Fail But SMART Status OK

I have a Mac mini Server from Mid 2010 running Snow Leopard Server.
Ocassionally, it'll freeze up with the spinning beachball wheel for a few minutes. This usually happens when opening an app or performing an app function from the menu bar. It's a pretty clean system—there are not many apps installed.
I suspect it's a hadrware issue. I ran Disk Utility's Permission and Disk Repair. All good. SMART Status is verified. So I ran the Apple Hardware Test. Everything passes except for the Hard Drive's "Full Read"—it fails because "Reading took longer than the average time". The Hard Drive "Short .. test" and "Check SMART Status" pass.
Does anyone have an idea of what's going on here? Is the hard drive the issue? I don't understand how there can be a read issue (or hard drive issue), when the SMART Status is verfied.

S.M.A.R.T isn't perfect. Neither is AHT for that matter, but if it is reporting that reading is taking longer than it should then an impending failure is likely. The occasional "wait cursor" appearance supports that diagnosis.
Consider yourself fortunate in that you still have the ability to back up anything important, and you can plan a convenient time for its replacement.

Apple Hardware Test (AHT) is GONE!! after Lion install

After installing Lion on my new early 2011 MBP the AHT is gone...
Pressing "D" will not load the AHT (it was installed and working fine in my MBP prior to Lion).
I called the APP hotline to inquire about it and the technician couldn't boot into the AHT on all the macs with Lion available to him.
(a report has been filed with the engineering team)
According to the newly updated KB: http://support.apple.com/kb/ht1509
QUOTE: "Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet."
After pressing and holding the "D" key the Mac just loads into the desktop... There is no online AHT or pre-installed AHT available...
>> Is anybody else having this problem?? <<
If you are having the same problem maybe you should also report it to Apple: http://www.apple.com/feedback/ or the APP hotline...

HOW TO FIX THE AHT PROBLEM IN LION:
Just to clarify what Francisco was saying in Spanish:
> The original AHT that came preinstalled in the MacBook Pro (and maybe all other Macs) is found in disk #2.
> Originally I thought the AHT had a different partition on the HD but it ends up being an extension of the OS.
> This is not installed in OS X Lion, If you used the USB key or download it from the App Store, the AHT will not be included.
> So, to install it back in, you can either run the install from the DVD (just make sure you don't install iLife again and other files which you may not need)
OR
For Road Warriors
Since installing the bundled package will also install other Snow Leopard files; You might want to try this:
> Download Pacifist ( http://www.charlessoft.com/ )
> Drill down the CPUHelpFiles install package and only install the CPU_AHT package.
By the way, there is no way of undoing this, unless you want to reinstall Lion from the recovery partition.
> Restart your mac
> Everything should be A+ ok
> To test what you just installed restart the mac and hold down the "D" key before the screen turns white/gray. After a few seconds you should see the AHT loading screen:
Done! there is no need to have that DVD with you when you travel...

Apple Hardware Test error 4SNS/1/40000001:ID0R-0.000 on Retina MBP

Getting the above error on my 3-day old retina MBP with 16gb RAM and 768GB flash storage. I had loaded Chrome, Firefox, VMWare Fusion, Office 2011, and all the Apple updates as of 7/3/12.
My issue may be related to similar issues I've seen on these boards, relating to sleep or wakeup causing the intermittent crash. Machine has also crashed (kernel panic) 2 times. Genius Bar employee downplayed the AHT altogether, saying it's a false positive since his more advanced tool reported no errors. They then kept it for a day, to run a "loop test," which also came back with no errors. Then, because apparently it is easier to re-load the OS rather than actually diagnose the issue, they re-loaded my OS clean. (Yay, now I can re-load all my apps, copy 200GB data back on, and THEN we'll see that it is a hardware problem.)
Tomorrow I'll pick it up from Apple and run the AHT again. If it errors out again, I'm not sure what to do...

One note I had neglected to mention is that the bar/band immediately above the keyboard gets very, very hot. Yes, I know that is where the fans are. However, all 12 of the MBP's at the Apple store did not have this extra-hot band, and those are on all day. My little Safari & Mail apps should not cause an overheat situation, on a functioning machine. Apple blamed Google Chrome for the crashes, downplayed the overheating, and downplayed the AHT results.
Update: I went to the Apple store today and took a look at the notebook. They ran their tests, had re-loaded the OS, and performed an undisclosed hardware repair. (They were helpful but vague as to what the actually did on the machine, hardware-wise.) They said their advanced tools & extended Loop Test did not indicate any errors or problems. While still at the store, I ran another quick test with the Apple Hardware Test, which came back with the same 4SNS error as mentioned above. I asked for a refund, which they approved (except they said I have to come back Monday since I bought the machine from Apple Business.)
When I got home, I ran an extended test with the Apple Hardware Test and got a *diffferent* error this time: 4HDD/11/40000000:SATA(0,0).
It's seems strange to me that the AHT shows 2 different errors, and yet the Genius' "advanced " tools find no errors. Thankfully, I will return this one (eventually) get a new unit. Thanks to everyone for helping. --Peter

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.

Disk repair and Apple Hardware Test says HD has no problem but grey screen still persists on MBP

5 days ago while on vacation, my MBP just froze with the grey screen, apple logo and spinning gear.
I performed all that was instructed on the following discussions:
http://support.apple.com/kb/TS2570
except Archive and Install installation of MAC OS X and Erase and Install MAC OS X since I was able to save my files in my husband's MBP via Firewire Target Disk Mode. At this point, I am still apprehensive in erasing my files and installing again the MAC OS X.
When I did the Disk Repair under the Disk utilities, it says that my Mac Os X is ok. (It also said ok when I did the fsck -fy when I till did not have my CD when I was on vacation)
I also tried the Apple Hardware Test (AHT) to further l test the hardware of my MBP and performed an extended checking and after an hour, its says that my HD has no problem.
Yet, after all these, when I restart my computer, it still has the grey screen with apple logo and spinning wheel!
Can anyone tell me what else can I do??? Appreciate any help!

I like the free demo of SuperDuper to make clones. It's free, Leopard and Snow ready and is easy to use. If you buy the full version you can do incremental backups.
You should use Disk Utility to do a Disk Repair, as shown in this link, booted up on your install disk, before you make a clone of it. I use DiskWarrior for that instead.
I then partition my external disk, in Disk Utility, with a partition that is the same size , actually a tad bigger, as my system disk. I then use SuperDuper to clone my system disk over to that partition.
With a clone on an external FireWire drive (USB drives are not bootable on PPC Macs but are on some Intel Macs) you can bootup on it to do your repairs, on the main drive, or just run your Mac anytime you have trouble with your main drive.
That's why I like clones better then Time Machine. You can just bootup on them and use your Mac.
On the DiskWarrior thing, I use DW once a month to try and catch errors in my system from getting too far out of hand. It has repaired every little and big issue I have ever had with my three Macs.
And I have had times when Disk Utility's Disk Repair says everything's fine but my system was still having issues. Disk Utility, in my experience, cannot be totally relied on to find and report all issues. It just isn't robust enough.
I run DiskWarrior, it does find errors, repairs them and I'm back in business. I swear by it!

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 failed

I have a 3 1/2 year old MacBook Pro 2.6 GHz. Suddenly I started getting kernel freezes....your computer need to shut down.... Sometimes I get the same message at upstart. Sometimes the screen starts blinking and them freezes with grey/green lines down the screen. The Apple hardware test failed with failure code: 4VCD/1/40000003: VideoController. I can start from the restart in hardware test.
Any suggestions out there?? Anything a non apple technician can do?

The service shop said they couldn't do the graphic card test, so they believe it isn't covered by the repair program. But they said the card is the problem, just not that problem

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.

Built-In Apple Hardware Test

From my understanding, all new Macs have Apple Hardware Test built in directly to the EFI. Does this also apply to the Mid-2009 MacBook? I tried holding 'D' on startup but just ended up with a white screen. Is there a different keystroke?

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

What does the error from my Apple Hardware Test mean?

I was doing some maintenance on my iMac G5 (Ambient Light Sensor) this past week and found that my Video RAM might be bad.
My first clue was that when I used the 'option' key on boot, one of the resulting screens was covered with vertical lines of about 1/16 of an inch.
My second clue was that after running the Apple Hardware Tests, iMac Version 2.5.1 (the one that came with my iMac's original 10.4 Tiger installation disks), I was told there was a Video RAM error, but am not sure if I copied it right because all the little vertical lines. Here is what the AHT reported:
** ERROR ** ** ERROR ** ** ERROR **
2ATI/1/4 113-xxxxx-117
** ERROR ** ** ERROR ** ** ERROR **
Does anyone know what all this means? When I run OS X my desktop doesn't appear to have any video problems, so I was taken be surprise.
Thanks.

Well I just wanted to chime in I know this is a little late, but I just picked up a iMac G5 for $50 that had this same problem, I would recommend you take the back cover off of the iMac and inspect the capacitors, I did and found a blown capacitor I took the logic board out took it to a local PC repair shop and for $35 he replaced the blown cap. They don't have to be completely blown to mess things up just domed or really anything other than flat. I came home put it back together and everything works great. just something to consider I mean for 30-50 bucks what could it hurt otherwise if no blown caps are visible then your video chip needs to be reseated and I don't know what to tell you on that.

Apple Hardware Test reports year as 4013 in diagnostics report? Why?
