IMac fan, hardware test result

My iMac fan is always running. I ran the hardware diagnostics and it gave me the following error code: 4SNS/1/40000000-9.000. Any help?

Means you have a sensor gone bad. Get it repaired ASAP.

I cant start computer the screen comes grey with apple logo.
Does any one know how to fix this preoblem with this?

That error shows that your hard drive fan motor is damaged. If you are not an expert user, take the Mac to an Apple Store or reseller to get the hard drive replaced, as it would be dangerous for your hard drive to use your Mac (if you can use it).

Hardware test result regarding fan

I just finished the AHT (Apple Hardware Test) and It told me it had found an error in the hardware. the error is: 4MOT/4/40000002: Exhaust-2216
what does this mean?
Thanks,

The last time I had fans replaced, the fans themselves were $17USD each, plus labor, which was $34USD.

Need a copy of the iMac G5 Hardware Test

Is there someplace I can download the hardware test for a G5 iMac?

The serial number will absolutely be required, because pretty much every hardware refresh results in a different version of AHT (and ASD) being used. For whatever reason, Apple does not make these programs cumulative. Each version only supports a very specific range of systems.
Not sure they will have kept copies of restore discs that old however, so the OP may well be reduced to trying to find something on torrent sites or some such. You could also try going to a local AASP where they can download a copy of AHT from Service Source and burn it to a CD.

Hardware Test Results?

I use the istat pro widget on my 15" Macbook pro which told me my right-side fan had stopped working but every now and again it appears to kick in. So I ran a extended hardware test and it returned this code "4MOT/1/40000002:Left_Middle-Front". Can anyone tell me what this is or what to do next? I'm hoping this is not the logic board, fingers crossed.

If your MBP is under warranty I would simply contact AppleCare.

Apple hardware test results means?

My older 20" imac intel crashes 1-4 times a day, freezes up, have to press power button to shut it down; ran apple hardware test twice and got these two alerts: apple hardware test 4MHD/2/40000004: 0x7c651f10 and 4MHD/2/40000004: 0x7ba72510; before running AHT, had already run diskwarrior, disk utility, TTPro, and they all found nothing amiss.
any ideas? much thanks.

I don't know what the errors mean but the symptoms could point to the memory. You've tried everything else how about removing one memory module at a time and rebooting to see if you can eliminate that possibility.
Good luck, Rick.

2008 Imac apple hardware test

I have a 2008 24" Imac running 10.7.5, my boot rom version is IM91.008D.B08, and my SMC version is 1.37f3. I'm trying to run the Apple Hardware Test but I'm not having any success; I depress the d key but it just restarts normally, same with option d. I checked out the firmware version and Apple says it's up to date. Maybe it's not possible? Thanks, mj.

Unless disc 2, "Applications Install DVD," states to use the D key on start up to launch AHT, you can't and need to use the disc. If the disc says to use the D key, then you need to restore the .diagnostics folder that Lion apparently blew away.
To do that, mount disc 2, launch the Terminal app in /Utilities, copy & paste this command into the window that pops up, and hit the return key:
defaults write com.apple.finder AppleShowAllFiles 1
OPTION-click & hold the Finder's Dock icon and select RELAUNCH. That unhides all hidden files/folders.
Drill down to /"Applications Install Disc"/System/Library/CoreServices/ and drag the .diagnostics folder into your SL boot volume's /System/Library/CoreServices/ folder.
Run this command to hide the normally hidden files/folders and RELAUNCH the Finder again.
defaults write com.apple.finder AppleShowAllFiles 0
Restart the machine and you should be able to boot into AHT when restarting and holding down the D key.

PB 17" Hardware Test Result-Error Code 2STF/1/4

I have a 17" Powerbook G4 running OS X (10.4.7). Today I was online on a cable modem. I walked away from the computer and then heard a high pitched sound. I had the sound turned all the way off so it wasn't coming from anything normal. It seemed as though the sound was coming from my attached external speakers but apparently that wasn't the source of the sound. It appeared to be still online but then everything froze up. Then the computer turned itself off when I tried to quit the Firefox application.
I had trouble getting my Powerbook restarted and when it did restart it showed the blinking question mark. I ran the Hardware Test and came up with an error code. It showed an error detected in the mass storage. The code was 2STF/1/4. Apparently there is nothing I can do to fix this on my own? This being Saturday I guess I have no computer for the weekend and maybe for a while. Does anyone have an idea how serious this error code is?

Hi--
Does anyone have an idea how
serious this error code is?
Based on the description of the sound you heard, and a Google search for the hardware error code, it sounds like your hard drive failed. My guess is that the high pitched sound you heard was either a bearing in the hard drive going (if they have such a thing), or the head scraping the surface of the drive (and thereby removing the magnetic media that holds the data).
One other thing that it might mean is that the hard drive controller chip, which is on the logic board, has failed. But that doesn't really explain the high pitched sound you heard (unless it was from the speakers, and was caused by an electrical failure on the logic board that leaked into the sound generating chip).
At this point, I think you need to have a technician look at the computer.
good luck,
charlie

Anybody know what my hardware test result code means?

My Macbook Pro 15" has been hanging and crashing a lot lately (just after applecare expired too!), I did a clean install and upgraded to 10.6, did the usual disk first aid (even checked for viruses) and after nothing helped, I finally ran hardware test from the install dvd and received the following error: 4MOT/2/400000004: Left side -3286; I know 4MOT is the logic board, but does anybody have any ideas what the rest means?

This is the counter-example:

Failure Code: 4HDD/11/40000004: SATA(0,0)
This is apparently a new hard drive problem? ... my mac mini has developed a "temporary getting stuck issue - with the spinning beach ball for about a minute or so 2-3 times a day - usually right after opening an application (like Mail, e.g.) - this just began happening since updating to 10.6.4 from 10.6.3... but the error code from the hardware test suggests a physical problem? Thoughts, and recommendations would be most welcome. The mini is about 1 1/2 yrs. old.
Also: from kernel log at "stuck" time: kernel[0]:disk0s2:I/O error.

Couple of things to do ... first, bring up Disk Utility (on your hard drive in applications/utilities) and see what it says for SMART status. If anything but 'verified' the hard drive should be replaced. If it says verified, it could still be failing and not tripping the SMART sensors. Download http://www.volitans-software.com/smart_utility.php and see what it says. It will show you the values of the SMART sensors and give you more information on the condition of the hard drive.
You could try booting from an OS X DVD, and doing a Disk Repair on your hard drive, to see what it can do or what it tells you. However, based on the error messages I wouldn't hold out hope that it will fix it.
If everything is backed up, you could try erasing the hard drive and writing zero's to it, using Disk Utility. That will reset the bad sector table, and might help extend the life of the drive. But disk I/O errors generally signal a failing hard drive. If you have Applecare, have Apple replace the drive.

Hardware Test results OK, but...

I added memory at a point before I began experiencing system freezes. Is it possible that something could be intermittently wrong with the memory, but the Apple Hardware Test doesn't catch it?

OK... Memtest ran all night in single-user mode and everything passed.
The reformatting a little over a week ago wiped Applejack, so I just reinstalled and ran it in full auto mode. It finished quickly and didn't reflect any abnormalities.
Apart from Applejack and Disk Warrior, which I bought because of the system freezes, there isn't any new software that would be conflicting. Nothing is in /Library/StartupItems except two folders for Pro Tools (which has been on my HD for several years without trouble) and a folder for Pace Support (iLok dongle). There is also nothing in my user (Admin) login items except iCalAlarmScheduler and System Events.
Again, the freezes (no error message is displayed) have occurred both while running various software and with nothing except the Finder running. Is there anything else I can try if another freeze occurs?

Freezing G5Quad, Ran Hardware test, result DIMM Error

Hi,
I have worked with macs for many years and I had never experienced such a problem. I have 2 Quads, one with 6 Gigs RAM and the other 3 Gigs. The one with 3 started freezing up randomly, sometimes during startup, sometimes after start up, or just after opening a program. The mouse would just freez. I could not do anything.Then I ran Hardware test and it came up with a DIMM error. it said DIMM J9600 had a problem, so I changed the possitions of my RAM and now it is working fine.
What I would like to know is how does a DIMM go bad. I had not opened my G5 for at least 4 months and it just happened from one day to the next. It also currupted my system disc, which I was only able to fix taking it out from the computer and putting it into my other quad and running Disc Warrior, which took more than two hours to fix.
Any ideas what must have happened???
Thanks, and sorry for such a long explanation.

Well - if you are now not getting the RAM error after switching slots, it seems possible that there was nothing wrong with the RAM and it was re-seating the RAM that fixed it.
Although the RAM is a tight fit in the slot, there are many small contacts and any contamination can cause problems - which re-seating can fix.
As you don't report getting the conventional RAM problem warning - bottom of the page here
http://docs.info.apple.com/article.html?artnum=302527
it could even be an intermittent fault, so it might be worth running the extended RAM tests - Memtest/Rember - linked-to here

Extended Hardware Test Results

Hi All
I have been having a lot of trouble lately (G5 1.8GhZ, 1GB RAM (2 x 512) 10.3.9) with kernel panics and freezes. I have fully reinstalled OS X but the problem remained. Eventually I ran the Extended Hardware Test (which took 45 mins) and I got the below error:
2MEM/5/4:DIMM1/J4001
I took this to mean that one of my RAM modules is the problem, but, this is only a guess.
Can anybody shed light on what this error is and maybe how to resolve it?
Many Thanks
BB

Just to load the fodder, that is exactly what was happening on my 4 month old PowerBook Pro; (including all the same software/system troubleshooting) and I got a 4MEM/1/40000000 error code. (it was also causing my Win setup on Boot Camp to wig out -- even worse)
What I was looking for here (somewhere) is a quick online reference to the code breakdown to tell me which module/slot is bad (one is from Apple the other from 3rd party -- both should be covered)

Apple hardware test result

My macbook pro keeps crashing. - black screen with an instuction to restart. I run the Apple hard ware test and it gave me this error code:
4MEM/3/40000000:1c0e 0990
Does anyone know what this means?
Does my new mac have to go to the hospital?

Hello!
I had the same problem and solved it. Please refer to the link below.
http://discussions.apple.com/thread.jspa?threadID=919711&tstart=30
This is a bad memory DIMM problem. You need to trace which one of the DIMMs is defect.
The problem can appear spontaneous (as it was on my MBP). Once you got this error code, try to make memory test.
There is very helpful program for memory test under Mac OS X. You can find it here http://www.memtestosx.org/

Blue Screening - after rebuild ran hardware test - results

Hi All
I just ended up with this error message. Have recently rebuilt again after numerous bluescreen / bootfail occurrences.
My warranty is up but I'm mostly curious to know if replacing the hard drive would likely 'solve' my problems.
All other tests were successful. Laptop is 18 months old and admittedly has had relatively heavy hard drive usage next to normal home laptops (saving, alterations, statistical analysis files, repetitive partitioning to install ubuntu in serial etc).
Thanks
Alex
