    Hey -

    This post is a duplicate of my post at the apple support forum - trying to see if anyone else has had similar experiences and can give me any help whatsoever...


    Hi there -

    I got my MBP back today, after having the logic board replaced to resolve the nvidea graphics card issue (

    After working with it for about 40 minutes the screen went blank. I ran the Apple Hardware test on restarting, and got the following error code -

    I've given it back to the guys who repaired it for further testing. They said that their diagnostics arent showing anything, but the Apple Hardware Test has come back with this error each time. I've searched around for information on this error, and there are suggestions ranging from issues with the logic board to a thermal sensor issue.

    I've found 2 threads in this forum where people have experienced the same sequence of events - logic board replaced for the nvidea problem, only to get this error code when the laptop is returned.

    Can anyone shed any light on what the problem might be? Has anyone else had the same issue?

    Any feedback would be appreciated.

    I had the same issue after sending my Macbook Pro in for the logic board replacement. What I did was just send it back to apple to have them fix it, it didn't list what they did to fix it on the paperwork I got back from them. Sorry I couldn't be of any help but my suggestion is to either take it directly to apple or call applecare and they should send you a box. Also if you want to show the tech the error message without having to run the test again goto your system profiler and look under diagnostics and it should be listed there.

    Thanks for that - from what Ive been able to find out, the error is a 'bad sensor error' which might mean that the logic board wasnt properly connected. I dunno if I can send mine back to apple - the replacement logic board came under and extended warranty but the machine is 2 years old and I dont have apple care... will have to see - hopefully it can be sorted relatively quickly...

    You should still be covered since it happened after the repair. If the authorized repair center can't fix it just call up apple and tell them you situation and they should take care of it. I believe you get a 60 day warranty after the logic board replacement and it seems to be related to the logic board.
