So a few hours ago I won this on eBay. It has a bung mobo, but $325 is still pretty good value for the rest of the parts, and with my MacBook now being out of warranty, it won't hurt to have a parts machine around.

I am not sure I believe that issue is logic board related. I've worked on thousands of Macbooks over the years and I can't really think of any time a spontaneous power off issue ended up being the logic board. I'd look into the logs and try it with a different top case. The power button could be having an issue and sending the signal to power off. If you don't have another top case, remove the current one and turn it on by jumping the connector the top case connects to with a T8 size screw drive, furthest to the left of the connector on the board. There are pads on most boards too but this is the easiest. Honestly, I've worked with enough Apple techs (while working for Apple for almost 3 years) to know the most of them are awful and would never trust any diagnosis given to by one. Maybe it's not as bad in other regions, but where I used to work there was a reason why people would have machines come in for repair and they'd get them back with 6 parts replaced for a simple issue. It's because the techs are terrible and just throw parts at machines because its easier to do that than troubleshoot.

Thats another thing...hell, it could be as simple as a faulty power adapter...but either way, the main reason I bought it is for parts, now that its out of AppleCare. I tend to keep my machines for a long time, so after they go out of warranty I typically like to pick up another one cheap for parts...I like to think of it as being a bit like having an "extended extended warranty" 🙂

Last one of these I worked on with that issue, it turned out to be a stuffed fan. First thing to check is for any thermal related problems that would be shutting down the system as a form of protection. May wish to also look into a replacement top case for it and see if that makes any difference failing a thermal issue. I'm aware that this machine is for parts, but I somehow can't help but think the logic board isn't the problem here. It wouldn't be my first guess anyway.
