Mar 23, 2015 12:16 AMby tobbenos,I have discovered that I have the problem described here: http://www.macworld.com/article/2062783/cures-for-a-panicking-mid-2010-macbook-p ro.html
Acknowledged by Apple here: MacBook Pro (15-inch, Mid 2010) intermittent black screen or loss of video Quality Program has ended - Apple Support
I experience frequent crashes with "GPUPanic.cpp:127" in the crash log. There is a problem related to switching between the internal Intel graphics and the Nvidia graphics. I have spoken to the local Apple retailer, which will repair the computer free of charge soon.
I do not know, however, whether this issue is related to the -340D error.

Using Apple Hardware Test - Apple Support
Your Macbook Pro probably was upgraded to use OS X Internet Recovery as some of the Mac which came with 10.6.x did have that option. It seems like, some of the models might have problem to access Internet AHT:

Not sure what error -340D means but if you haven't tried yet, i would suggest to turn OFF your router and after 2-3 mins turn ON again. Try with different network as very often issues with starting Mac in Internet Recovery are caused by network settings. This could be the same issue...
