    Thanks! I dropped it off at the apple store and they said they were going to do a "full ASD TESTING" and called me back today that they couldn't find any issues.


    Does "full ASD TESTING" include the VST test?

  • nicksmacalret Level 1 Level 1 (0 points)

    Hi bodacious_sd,


    AST - Apple Service Toolkit is a quick set of test that run in their own environment and is intended to find quick and obvious hardware faults. Eg, faulty temp sensors, fans that don't spin, etc.

    ASD - Apple Service Diagnostic is a fairly comprehensive test that is run through a cutdown OSX. It includes many of the AST tests but also runs software to stress the hardware in an attempt to elicit faults. It has a harder time finding faults because the hardware is abstracted from the software by the OS but it can do things that AST can't because it has a full OS.

    VST - Video Service Toolkit is available as a test that can be launched from the home screen in AST but only on machines that meet the requirement (15" Mid 2010 MBP) and only after the normal set of AST tests have been run and the machine rebooted. I expect that what is happening is that when AST runs on the machine for the first time, after performing the test, it uploads the results to Apple. Apple know know that this machine is eligible to have the fault so when AST is loaded for the second time on the same machine, it is told to present the VST option.


    It's a convoluted process but it works and only takes about 10min.


    AST is loaded via netboot and is updated regularly so it can include new code to find new faults easily. ASD is released at the same time as a new lineup of hardware and is never updated. So if a new fault is found for a given system then ASD can never be updated to know about it.


    So in answer to your question, no they did not run the correct test so they would not have found the fault.


    Remind them to read OP555 which they have access to via GSX and then they can follow the official Apple service guidelines to find the fault.


    Good luck, let us know how you get on.

    Is there a technical reason why this is limited to the 15" models? I had the same problem with my 17" 2.66 GHz i7 mid-2010 MBP with GT 330M. I started getting the same NVRM: Read Error kernel panics and gray 'computer needs to restart' screens after about six months of use, running Snow Leopard. Finally one morning it turned off abruptly without warning and wouldn't turn back on or show any signs of life. I had to pay out of pocket for the logic board replacement six months out of warranty. That was in May, and now since September it's been hanging on the graphics card switch intermittently again - going from discrete to integrated graphics smashes the screen into one half of the display horizontally and distorts everything to a green color. This is the first I've seen of T

  • Sunnycide Level 1 Level 1 (0 points)

    ^ sorry about the truncation! Anyway I'm newly aware of TS4088 and wonder if it would be appropriate to ask for my 17" (with the same 2.66 i7 and 330M GPU) to be inspected under this pronouncement. The 90 day repair warranty was up in August so I'd otherwise be looking at a second out-of-pocket logic board replacement.


    I've actually already bought another 17" just out of concern for general stability, but having already reduced the former to a $3,000 doorstop after less than two years of use has not been a fulfilling conclusion.


    What do you think? Are these GPU issues categorically distinct for 15 & 17" MBPs with the same CPUs, GPUs & chipsets? I'm not otherwise sure why they would make explicit that only 15" models qualify for this service; hopefully it's not simply a result of underrepresentation of 17" owners.

  • bodacious_sd Level 1 Level 1 (0 points)

    I got it back from the store after explaining them what I wanted them to do. The short answer was (via telephone when they called me that it's ready) - yes we did everything, though it didn't sound like a technical person, so not sure if they did run the test procedure or not.


    I got it back and the kernel panics are still happening, so I started the disabling various pieces of software.


    My current suspect is the Twitter client. After not running it for a while the panics almost went away (at least they substantially lessened - maybe once every 3-5 days now), but they're not completely gone yet.

  • spritrig Level 1 Level 1 (0 points)

    I am getting the black screen when I plug in the external monitor on my 15" Early 2011 MBP with AMD 6075M GPU.     Reboot starts with red striped screen followed by black screen with backlight on. 


    This has been an absolute nightmare, stopping my work for a month so far.  Restoring my data from backup is a waste of time because the computer crashes and frequently corrupts the hard drive (even with new hard drive).  See photos on my thread.  (Black screen wasn't interesting to photograph.)  I rarely get a panic notice.

    So I have an Early 2011 MBP manufactured in Feb 2011.  This is in the last month of the April 2010 to February 2011 manufacture period.  However mine is an Early 2011 rather than Mid 2010 MBP.  By manufacture date I should be covered.  What about the Mid 2010 vs. Early 2011 designation?  Seems kind of ambiguous.

  • CWasko Level 1 Level 1 (0 points)

    My computer has been having this issue for quite some time now.  It is a Mid 2010 MBP 15".  I took the computer in a few months back and Apple said it was the hard drive causing it.  They replaced the drive, and I re-installed everything from scratch.  The HD replacement did solve some other minor issues (either that or the rebuild did); however, it was crashing just as much with the noted panic's in this thread.  So, I started to do some research and found this article.  I took the laptop back to the Apple Store on 12/26 and got it back 12/29.  I referecend this thread and asked them to do the VST.  They actually could not get the VST to run while I was there.  But, I gave them a very detailed description of the problem and obviously referenced the fact that the HD replacement didn't resolve the issue.  The Apple genius said they would replace the mobo.  Upon reciept of the computer on the 29th, Apple verified that they did find that the mobo was messed up.  I also have not had a single panic since getting it back.  So, we'll see how it goes, but it is lookign good so far.


    My advice to anyone is to just stay persistent and bring as much data as you can.  Make sure to leave the crash logs on your computer and ensure that they look at them while you are there.  I was even able to get the computer to belly-up while there, so that helped greatly.  Good luck!

    finally 15 days after I left my macbook in the service (in Mexico), they replaced the logic board, since that, I'm not longer experincing the kernel panics again! but was really deficult to get it repair, because no Apple test detected the problem, neither the VST, all seems to be "ok", so they keep the mac in order to reproduce the error, and they did it more than once.


    The problem now is my hard drive, since this kernel panics started (like 1 month ago) I had to repaired frecuently throw the disk utility partition, and now I think got worst, I'm suspecting all this seriously damage my HD.


    Does anyone is having troubles with the HD since this issue???


    And one more thing...

    now my microphone is not working since I take it back from the service...


    hope everyone can fix their macbooks!

  • apple242 Level 1 Level 1 (0 points)

    Had problems with the hard drive after the logic board replaced as well.


    Regarding the mic - if the audio settings are ok, they may have forgotten to connect it.

  • spritrig Level 1 Level 1 (0 points)

    Vitamineme, I got mine to stop crashing reverting to Snow Leopard and by setting:


       System Preferences --> Energy Saver & uncheck "Automatic graphics switching".


    My computer reliably crashed by using iPhoto in either Snow Leopard or Mountain Lion (ML, or by plugging in the external monitor on Montain Lion.  I belive turning off the graphics switching will work on ML as well.  It hasn't crashed for 5 days, and I was having crashes multiple times a day before.


    This will get my work going again.  After I go to the USA, I will follow Apple's remedy instrtuctions.

  • spritrig Level 1 Level 1 (0 points)

    alekb I frequently had to repair volume and repair permissions after crashes to get it to boot again.  I have replaced my 750GB hard drive.  I was able to get the drive in Mexico by buying a 750GB Seagate external USB drive for 900 pesos at Office Max and removing the drive from the case. 


    What did it cost to replace the logic board in Mexico?

  • alekb Level 1 Level 1 (5 points)

    Hi spritring, the replacement is part of the plan TS44088 and is free of charge, it's a expensive repairment about $17,000 pesos if you pay for it.

  • vitaminme Level 1 Level 1 (0 points)

    Hi Spritrig,


    i took it to apple, they replacing my logic board.

    yes previously i was using intel graphic card to save myself from reboots. Really happy that they fixing it for free, else i would have too sell my house to get it fixed

  • vitaminme Level 1 Level 1 (0 points)

    No more reboots after replacing logic board. Tested it for a week. Thank u Apple!
