  • Apple Hardware Test detected an error code... now what?

    I ran AHT and I got this message:
    Alert! Apple Hardware Test has detected an error
    4M0T/1/40000003:HDD-1424
    Can anyone shed some light on this?
    My early 2008 iMac has been having issues with the spinning wheel when opening and using applications. I can't seem to pinpoint when it happens, but many times I will have to shut down or power the machine off to stop the wheel of death from spinning.
    Any help would be greatly appreciated.

    bump... any one else?
    I was able to boot the machine up today and I am noticing the top of the machine is getting very hot. Could this be the overheating issue I have read about here in discussions?
    I was also able to transfer files to an old eMac, so I am backed up, but that transfer slowed after the machine warmed up. I would shut the iMac down and let it cool... it then transfered great while cool but slowed when it heated up....
    I am taking it in to a local authorized repair shop Monday morning..... just hoping for some more thoughts before then.
    Thanks!

  • Apple hardware test detected an error.

    Well, I'm back (see older post) . Just ran  Apple hardware test and it says it detected an error. What should I do from here??
    I using the original Tiger discs which came with the computer. The Leopard disk was just a drop-in CPU disc they gave me to upgrade from (when I purchased the iMac in 07). Can I just use the Tiger disc again to run Disk Utility and try to fix the HD?

  • Where do I find a list of error meanings for Apple Hardware Test?

    I think My 27" mid 2011 iMac has a faulty thermostat on the ODD. I ran the Apple Hardware Test and the error message was 4M0T/4/40000002:ODD-0. Where can I learn what this error code actually means?

    That error message means that there is a problem with the optical drive fan motor. I recommend you to make a backup of your files and take the Mac to an Apple Store or reseller in order to prevent any problem.

  • What does Apple Hardware Test error code 4MEM/1/40000000:OX3bb6b190 mean?

    Mozilla kept crashing so I did the Apple Hardware Test and got error code 4MEM/1/40000000:OX3bb6b190. I reinstalled MacOs 10.4.4 (after saving the important stuff to disk of course) and it took about 10 tries to get the 2 disks installed. After the installation, I tried to update to 10.4.5, and when I restarted, the screen was blank. The only disk the computer will start with now is the No. 1 installation disk. What can I do?

    Hi
    A MEM error code generally indicates a faulty RAM Module. In my experience most RAM manufacturers offer at least a 5 year warranty of their RAM products. Some warranties are for 10 years. Sometimes reseating (taking it out and putting it back in again - properly) the Module will 'cure' the problem. Run AHT afterwards if you try this option first.
    If you can remove the offending module and still have enough RAM to be able to do what you need to do then do so.
    If not take it to your nearest Apple Repair Specialist who should fix it for you or replace the faulty module yourself and deal with the RAM manufacturer directly.
    Judging by the footer to your post you don't seem to have had much luck with this model have you?

  • G5 Full Speed Fans/ The Apple Hardware Tests Error Code

    Since yesterday My DP1.8 G5's fans are max speed like jet engine. I tried PMU resets , Disk warrior. But nothing helps. The Apple Hardware Test gave me error code of "post/192/0" . Do you guys know what does this error code mean?
    Thank you.

    Hi-
    Welcome to Discussions!
    I think thast the error is related to the "Power On Self Test", or POST. When you start the machine, are there any beeps, or power button LED flashes? If there is a POST error at startup, the power LED would flash in cadence with the beeps..
    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
    5 beeps = processor is not usable
    Do you have any new RAM installed?

  • 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.

  • Hello. Apple hardware test has detected an error. 4SNS/1/40000001:TN1D--1.000

    Hello. Apple hardware test has detected an error. 4SNS/1/40000001:TN1D--1.000  Anyone knows what that means ? OS doesn't boot. Maybe it's hard disk error ?

    It means your screwed if you're out of warranty.
    That error translates to your northbridge temperature sensor is bad- BUT IN MAC "GENIUS" LAND, that means you either need a whole new logic board (a $700 part) or buy a new MacBook. On the non-unibody MacBook pros, you could have came to my store and spend $75 and had a working computer the same day- this is no longer possible on the unibody MacBooks.
    WHY, WHY, WHY?
    In a bold design move, Apple decided to SOLDER the thermal sensors to the logic board (along with many other components such as the video, graphics and IO), thus rendering these parts NON-SERVICEABLE by us independant technicians. Apple's reasoning is that they can "make their notebooks thinner", but why sacrifice performace for asthetics? Who cares, buy a new MacBook.
    WHO NEEDS TEMPERATURE SENSORS?
    It doesn't matter if your laptop is running hot or not, when a temperature sensor goes bad on a Mac, it shuts your computer down to prevent further damage. Apple was the first company to implement this "failsafe", now PC motherboard vendors are following suit after watching Apple's stock soar. What this means: Is that you could actually have a perfectly functioning MacBook except for one thing; the little guy who's sole purpose is to report whether it's not the computer is running hot or not has decided to not show up for work, so they closed up shop. If you ask me, it's the equivalent of a restaraunt closing on account of not having a dishwasher- but that's just the opinion of an ex-certified ACMT and what do I know- I'm not a "genius" or anything.

  • HT201257 mac os x 10.4.11 tiger: apple hardware test has detected an error (what does this mean): 4SNS/1/40000001:VDOR

    Can someone help?  I did an apple hardware test and it has detected an error:  4SNS/1/40000001:VDOR
    What does that mean? Can i correct it myself? how?
    my computer is  "tiger" mac os x 10.4.11, Processor: 2.16 GHz Intel Core 2 Duo,  Memory: 2.5 Go 667 MHz DDR2 SDRAM

    Thank's for answering, realy appreciate your time,
    A technician had installed last year "mac os x snow leopard 10.6" (family pack) at around $49.00 - I had originaly mac os x 10.4.11 (tiger).  He had changed my hard drive, added memory: 2.5 Go 667 MHz DDR2 SDRAM, processor is: 2.16 GHz Intel Core 2 Duo  (he told me he had to change my hard drive probably due to a power shortage. Before he did the changes, I had done a hardware test: it gave me the same error as today 4SNS/1/40000001:DVOR,  He cleaned the inside, but he did not change any sensors. What am i to do???
    Not too long ago i started having problems. (probably from a power shortage, at one point.  I don't know if my external back up got corrupt. so i don't want to use it. He had eraced tiger 10.4.11 and installed snow leopard 10.6.
    I eraced snow leopard and installed mac os x 10.4.11 (that came with my computer).  
    I wanted to install mac os x 10.6 (snow Leopard) without eracing tiger (chat sites say you can do that) but it said it couldn't use my hard disk because of my memory:  my info says: used: 18,78 Go on the disk, available: 446.66 Go, Capacity: 465,44 Go
    So that's when i did a hardware test with the CD1 of mac os x 10.4 (tiger) and that where i got the message.
    If i have a sensor problem, then i guess i'm waisting my time trying to reinstall mac os x 10.6 (snow Leopard) or am i doing it wrong.  I was told i could leave tiger there and upgrade directly to snow leopard, without installing mac os x 10.5 (leopard).  
    Thank again

  • Will Apple Hardware Test definitely detect RAM errors?

    Hello,
    Been having various problems with Leopard/MacBook. Someone suggested running Apple Hardware Test, which I did, in extended + looping mode all night (it cycled 6 times). The test turned up nothing. Can I take this to mean that whatever problems I am having are definitely software related? I am not familiar with the AHT, don't know exactly what it does, nor how I can interpret a "clean" result...
    Many thanks for any advice/tips.

    No indeed (just "Colin" is fine...)
    My problems have mostly been documented by other people, and I have just been monitoring the discussions on these issues.
    Specifically (at the risk of getting off-topic):
    1) inconsistent shared server behaviour: I have 3 other macs at home - an iBook and a G4 MiniMac running Tiger, and a G4 tower, also running Leopard - and most of the time, the tower doesn't show up at all, but I can connect to it via CMD-K, the MiniMac shows up in the sidebar, but won't let me connect, and the iBook, when it is running, behaves normally. Oh, screen sharing doesn't work either: it tries connect but hangs (except for the iBook, which works). I could connect to all four quite normally after upgrading to 10.5.0, using the sidebar icons. Everything worked fine until sometime after the 10.5.1 update, when suddenly everything went pear-shaped. Nothing has changed in the configs of the other machines, and the iBook and the MiniMac are identical in terms of software config (but behave differently as regards this problem?!?)
    Closing Airport and reopening it makes the icons reappear in the sidebar (all of them, G4 tower included), as does relaunching the Finder, but doesn't change the behaviour: I still can't connect. When I try to use the sidebar icon for the tower, it disappears (the icon...)
    As far as I can tell, trying to operate shares from the G4 tower works as Apple intended (although I admit I have not exhaustively tested every option, as I don't have unlimited time...)
    2) Lost my printer connections, both at work and at home. I managed to reestablish them at work, but I tried so many things that finally I'm not sure what actually worked. No dice at home (shared printer on the MiniMac... same problem as (1) I guess.)
    3) the dreaded Keynote spontaneous reboot problem (I placed a reply about that last night here:
    http://discussions.apple.com/message.jspa?messageID=6630702#6630702
    4) diverse weird things, like
    4a)iCal which had doubled all my events the last time I opened it. I had to manually delete one copy of every event I had entered, whereas I made these entries several weeks ago, and had consulted them many times... I'm thinking this is perhaps a result of the brutal reboots caused by (3)? Having deleted all the doubles, iCal seems to be behaving normally again.
    4b)screen resolutions on my slave screen suddenly failing to select properly. I move my MacBook between two different external monitors, one at work, one at home, and their resolutions are different. Initially the MacBook had no trouble detecting and correctly setting the resolutions for the two screens, then suddenly my home screen went weird on me, and required a manual reset. Again, this was a once-off, and does not seem to be repeating (yet).
    4c)sluggish performance with some apps that are normally quite snappy, like Firefox, which seems to hang a lot loading pages, Keynote (saving is often painfully slow), and indeed, trying to copy a 250Mb file from the tower to the MacBook via Airport (having connected using CMD-K) said it was going to take 33 hrs, which I thought was a bit rich...
    4d) hot-swapping a usb pin for a keyboard+optical mouse receiver from the tower to the MacBook sometimes causes something inexplicable to happen to the MacBook's keyboard: both the Caps and the NumLock LEDs come on, and the keyboard has jumped into some config other than what it is normally in (French). I have not been able to determine what the keyboard actually thinks it is when this occurs (3 times now). The command keys (ctrl, alt, cmd) do not appear to work at all. Rebooting corrects it.
    All up, pretty irritating, and a huge time waster, as you can well imagine. I stuck a bit of a rant on the discussions the other day in a moment of intense frustration, which got zapped by the moderators (probably not unreasonably!), but not before someone replied suggesting that it might be bad RAM, hence my questions here.

  • Error Codes after Apple Hardware Test...

    After someone here told me I've been experiencing kernel panics, I did some digging on the x lab site and re-ran the Apple hardware test in loop mode. after 17 runs, it returned the error:
    4MOT/2/40000005:Right Side
    I can't seem to find a list of error codes anywhere. My MBP has two 1GB RAM chips, both were pre-installed when I got the machine from Apple. I haven't tried switching them to see if the same error is returned on testing or with ONLY one or the other installed to see if this is truly a RAM issue. I thought I'd post to the forum for ideas first...

    I'm afraid I have no idea. If you have AppleCare, I would ask them about the error code. You do have a different error code (/2/ not /1/ and different number after the second slash) than the link, so perhaps it is not a fan motor that is your problem, though I'm hard-pressed to think of what other motors the MBP has (I don't think the hard drive is on the right side, for one.) Alternatively I can imagine, since you said it took you 17 tests to get the result, that this is an intermitent problem--for all I know, just a slightly loose/poorly soldered wire--and so istat hasn't detected the problem yet.
    I think AppleCare or a Mac Genius is your best bet, if you have the one or can get to the other. In particular, unfortunately, Apple does not seem to publish the hardware error codes; it only makes them available to techs.
    Good luck!

  • 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):

  • -3403D error when attempting Apple Hardware Test

    Hi everyone,
    I want to perform an Apple Hardware Test. I restarted, pressed option+D, and a globe appeared. After a minute, however, the following text appeared:
    Apple.com/support
    -3403D

    Your Macbook Pro came with OS X 10.6.x and to run Apple Hardware Test you can use bundled with your Macbook Pro Application Disc:
    Using Apple Hardware Test - Apple Support
    Your Macbook Pro probably was upgraded to use OS X Internet Recovery as some of the Mac which came with 10.6.x did have that option. It seems like, some of the models might have problem to access Internet AHT:
    Computers that can be upgraded to use OS X Internet Recovery - Apple Support
    About the "Apple Hardware Test does not support this machine" message - Apple Support
    Not sure what error -340D means but if you haven't tried yet, i would suggest to turn OFF your router and after 2-3 mins turn ON again. Try with different network as very often issues with starting Mac in Internet Recovery are caused by network settings. This could be the same issue...
