i have the original logic board. is there a way for me to tell which board it is? is there a number between 820-2850 to 820-2195 that are ok?
i also got mine in dec of 2010 so it was late in the production cycle with this product. i believe it was introduced in april 2010.
also, are you just throwing up the word "deeprooted PCB issues?" this is a new wording that i haven't heard of regarding the model MBP 6,2 graphic-related kernel panics.
don't be offended though. i also made up my own wording in my earlier post calling it "anonymous defect."
no one, even apple knows exactly what's causing the gpu-related crashes in mavericks and mountain lion. they also echo the same "manufacturing defect" lingo. this was confirmed when i chatted with an apple rep online a few days ago. but, re-iterated, if i can remember... something like... "i don't remember anything changing with the 3 year from purchase coverage."
i guess they don't like to take care of their own mess, or only are willing to take care of it if its 3 years from purchase.
even an apple rep confirms that its a "manufacturing defect." so, the obligation is apple's to fixt it regardless of any coverage window.
i am sticking to this story. and i am not scared of any "deeprooted pcb issues" this mbp may or may not have.
PS-- did you even read where i said my computer works fine in snow leopard and now under os x lion? i don't think you did. tsk-tsk!
It's actually quite simple. I take no offense at all!
Apple like to manufacture quiet computers. They also like to make slim computers. They also like to make powerful computers.
When you combine all of this in along with the fact that those machines have no bottom or side ventilation besides that tiny pathetic exhaust out the back, you get a very hot running machine.
All of them have this. The boards with core i processors run particularly hotter. The 820-2915 board(early 2011) runs so hot that out of the box, I can get the machine to throttle. No dust, thermal paste, in a 65f room. This causes the GPU to overheat and die.
A cool part about the 820-2850 machines is that, regardless of how hard you run them, for the first minute or two it is on - the fans stay silent. You can kill an 820-2850 in under 3 minutes by mining litecoin on it before the system tells the fans to kick in.. it's insane how bad the thermal management is on the MC371 2010 machines.
The 820-2850 has PCB faults where they just die and there's no apparent reason for it. It's not just GPU failures, there is more to it than that. While performing a standard repair on an 820-2850, it'll have no power, or behave erratically. If you search for "as is" dead motherboards, you'll notice there are substantially more 820-2850 out there than almost every other 15" Unibody board combined.
The reason you do not hear about this is because there are only a handful of companies within the U.S. that bother doing component level rework on Apple motherboards as a volume business. Some such businesses are..
a) L2 Computer
b) Assetgenie
c) Brickfence
d) us
e) probably others I haven't heard of..
Most people are just guessing at the problem or copying and pasting what some low level customer service rep told them. I'm sure if you ask anyone else who does this work, they will tell you that they hate the 820-2850 for the same reasons I do.

Yeah man, not really tsk tsk,
I don't have much to lose here, you do.
I'm trying to save you from being stuck with a lemon, and I'm giving you insight and ways to figure out which board you have so you can make an informed decision, for free, during my free time.
If you'd prefer to go over semantics of what I did or did not read in a post that has P.S. P.P.S. P.P.P.S over and over again, feel free to do that, I'll exit stage left.
