Error code 4M0T/4/40000002: Left side -0

My computer screen suddenly wigged out while I was in the middle of surfing the web.  When I restarted it, everything seemed normal until it wigged out again a few seconds after rebooting.  Now When I start my computer the screen just remains gray.  I ran a system hardware test and it came back with the error code: 4M0T/4/40000002: Leftside - 0 .  Does anyone know what this means?

Apple doesn't publish a translator for the codes but, based on what had been posted elsewhere, I'd say your left side cooling fan motor is failing or has failed. The video artifacts are probably due to overheating of the graphics chipset. If the gfx chipset fails, it means an expensive logic board replacement.
To prevent any damage from excess heat, I recommend that you discontinue using the computer until you can get Apple to check it.

  • What is this error? - 4M0T/1/40000002 left side_981 error

    HI,
    When I ran the Apple Hardware Test this was the error message i got - 4M0T/1/40000002 left side_981. What is this error?
    Hoping for an answer to this query.
    Thanks!

    It's a failed or failing fan motor. Get it replaced ASAP. Don't use the machine with half its cooling capacity missing or impaired.

  • Is this major?! Hardware test error code 4M0T/4/40000002:HDD-0

    I ran a thorough hardware test on my 2010 iMac11,3 yesterday and came up with this error code. I then used disk utility to try to repair the disk and ran another thorough hardware test and the same code appeared. Does anyone know what this error code means? and whether I should get it fixed ASAP?
    I'm asking since this is my work computer and I really need to have it around and can't risk having repairs take a week or so to get this error fixed. If this is major I'll probably move all my work files onto my MBP n try to work on them there but that would be my last resort.
    Any help would be much appreciated!! Thanks!

    iStatPro says my hard drive fan is not spinning at all...that can't be good..I guess i'll have to bring this baby in for some servicing.
    Watch the temp of the HD; I don't know what the max should be, but be careful not to damage it by letting it get too hot.

  • Hardware Error 4M0T/4/40000002:Right Side - 0

    I had problems of frequetly shut down / Hang of MacBook Proof and Apple Hardware Test Detects error as 4M0T/4/40000002:Right Side - 0. any one can help for the solutions of error.

    Welcome to Apple Support Communities
    The error message indicates that a fan motor of your Mac has stopped working (it looks like the right fan).
    A fan is not working and this may cause that your Mac gets overheated, that may cause that your Mac turns off automatically after reaching a very high temperature. Make a backup of your files with Time Machine and take the Mac to an Apple Store or reseller to get your computer repaired. Copy the error message and take it with you

  • 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.

  • Error code 4Mot/1/40000002:HDD-0

    With the following error will I have to replace both the hard drive and HD fan?

    Probably either the fan motor, a temp sensor that controls it, or the logic board part that handles info from the sensor to the fan. Mot means motor and HDD is the hard drive, so it's something to do with the fan that cools the HDD. No matter what, be sure you have a backup b/c you're likely on borrowed time. Only an Apple Store or service provider can tell you what needs to be fixed.

    It means the fan motor is not working or not working correctly. Take it in for repair.

    You have to take the computer to the Apple store as soon as possible.
    Interpretation of these error codes are very difficult.
    There is no published info about these codes from Apple.
    Best.

  • What is the 4M0T/4/40000002: Exhaust-0  error?

    I know that something is wrong with my computer lately because when I try to watch a video, or using skype, or media applications and programs, my computer starts freezing and the pointer moves really slow...I did the hardware test and it said that my computer has the 4M0T/4/40000002: Exhaust-0 error....but what is the problem? does it have relation with the fan or something, because also it gets really hot when I'm trying to watch any video

    Also, stop using your mac.  If indeed the fans have died, your mac has little defense against heat and further damage could be done.  Turn it off and don't turn it on again unless told to do so by either a genius at the Apple store, an AASP rep, or a technician at another qualified repair facility.

    Trashing the preference file may help, as I've outlined in the topic I've linked to. Otherwise, follow the steps regarding removing 3rd party QuickTime components. Also, see the final post by the OP (EEye87) regarding how his problem was resolved (a combination of trashing the preference file and the 3ivx component).

  • What is 4m0t/4/40000002: exhaust -0 error?  black creen also.

    I need help lol... I have this macbook 2012 mid 13 inch and all of a sudden this morning it stopped working... like it turns on the keyboard and everything but the screen doesn't turn on and with a flashlight I can see the screen so it's like the backlights failing. Not the inverter.  What do you guys recommend I should do? Do you think that 4m0t/4/40000002 error is making the screen very low light?  I really need a flash light to see can't see the screen without flashlight. Also, as I was doing this hardware test the macbook was really hot. Like burning my hand.. it was tested while I had the flashlight on.

    Also, stop using your mac.  If indeed the fans have died, your mac has little defense against heat and further damage could be done.  Turn it off and don't turn it on again unless told to do so by either a genius at the Apple store, an AASP rep, or a technician at another qualified repair facility.
