What are the meanings of Apple Hardware Test error codes 4m0t/4/40000003:hdd-1300 and 4m0t/4/40000003:hdd-1308?

what are the meanings of Apple Hardware Test error codes 4m0t/4/40000003:hdd-1300 and 4m0t/4/40000003:hdd-1308?

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.

  • What do Apple Hardware Test Error Codes indicate?

    I recently installed new 1GB memory modules in both slots. When running the Apple Hardware Test, I got the following error code:
    post/0/2048 S0DIMM0/J20STANDARD
    Does anybody knows what this means? Up in the Test Results Box, it said Memory passed.
    Do I have a problem or not?

    I've had little luck finding a compilation of those AHT codes and their meaning. In your case, "post" is probably "power-on self test," the routine that all Macs run at startup to check for problems.
    2048 is the total RAM qty in MB.
    J20STANDARD is the logical name of one of the RAM slots.
    Run System Profiler and see what it shows for when you select "Memory" from the left-hand pane. On my 1Ghz 17" PowerBook, Profiler shows one slot as J20STANDARD and the other as J23REVERSED and it runs fine. Profiler will tell you if the modules are matched for speed and CAS latency.

  • 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?

  • Apple Hardware Test Error Code     " 2STH/1/2:CPU A AD7417AD1 "

    Hi All,
    I have a G5 2.5 GHz dual processer that seems to work fine after 14 months. But when I run the Apple Hardware Test, I get the error message listed in my subject above. I talked to Apple and took the machine in for service. Servicer said get the latest upgrade of the AHD and try it instead of one that came with my machine. After some work (a good bit), I got Apple to send me the upgrade and when I run it, I still get the same error code! Does anyone have any suggestions? I could sure use them. Thanks,
    Chuck

  • Apple Hardware Test Error Code

    Hi,
    I've recently tested my machine using the Apple Hardware Test, and received the following error code:
    4MHD/2/4000 0004: 0x3ca74c90
    Has anyone perhaps encountered this same code before perhaps & could they perhaps shed some more light on it?
    Funny thing is, apart from that, my iMac is working perfectly. ( Although I am backing up every day now - just in case )
    Intel iMac 20 inch   Mac OS X (10.4.6)   1GB RAM, 250 GB HDD, 802.11g, bluetooth,etc

    When your data backup is finished, call AppleCare and ask the question. You may need to get the machine repaired.

  • What are the best apps to monitor tests and emails on childs phone

    what are the best apps to monitor tests and emails on childs phone?

    You could simply log into your child's email with the password that the two of you agree upon, and monitor the emails manually.  As for the texts, you could purchase a separate device, and use the child's Apple ID to monitor the iMessages.  For SMS/MMS, no way to monitor it.  You'll have to use the app called 'Random Parental Inspections'.

    If you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then you can get a clue to what it is, and potentially use it, by going to https://appleid.apple.com/ and clicking 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you should see an option to send security question reset info to your rescue email address.
    If you don't have, or don't want to use, your rescue email address (you won't be able to add/change it until you can answer 2 of your questions) then you will need to contact iTunes Support or Apple to get them reset (which will be by phone as they need to verify your id - we are fellow users here on these forums).
    e.g. you can try contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management , and then 'Forgotten Apple ID security questions'
    or try ringing Apple in your country and ask to talk to the Accounts Security Team : http://support.apple.com/kb/HE57
    When they've been reset you can then use the steps half-way down this page to add/change rescue email address for potential future use : http://support.apple.com/kb/HT5312 . Or you could change to 2-step verification : http://support.apple.com/kb/HT5570

    what are the payment plans Apple has for international buyers

    There are none.  If you want to buy an iPhone, then you'll need to go and buy one from an Apple store in your country or one of the phone carriers in your country that offer iPhones.  If you live in a country that does not have an Apple store, then go to an Apple re-seller.  You may be able to purchase online if there is an Apple store online for your country.
    These are your alternatives.

    Does anybody know what hardware test error code this is 4SNS/1/40000001: TCOH -1.704
    Trying to track down fast running fan that will not reset and this error came up.

    only apple techncians have access to what those codes mean.  It is sensor related, but as it is a hardware problem, you need to bring it into an Apple store or AASP to have it correctly diagnosed and fixed.

Maybe you are looking for
