So I have a 2012 MBP which was purchased from the refurbished Apple Store quite a while back. It was running pretty well until a lightening storm fried my modem, router and hit then hit the MBP. I had the MBP plugged into a surge protector but unfortunately i didn't have the ethernet cable protected and that's where the damage came from. I had it beefed up with an SSD and 16GB of RAM so with the i7 running at 2.9 Ghz it was pretty fast even for today's standards. I honestly thought that it would never boot up again... I always back up data so that really wasn't the issue for me. I'm just kinda attached to it...I I believe that the 2012 models were the last ones where you could actually get in there and replace RAM and the HD quite easily. The Geniuses at the Apple store couldn't do anything for me....they gave me a flat fee fix of $288 to replace the motherboard and whatever else it needed. So seeing that for $300 I'd have a working computer again instead of a paperweight I went for their offer. It came back like brand new and I'm very happy with the outcome. I don't use Time Machine so it was a real pain to get everything installed again. It took me almost a week. I even decided to install a Samsung 1TB EVO 850 SSD because I felt it needed a hug....LOL. Happy ending feel good story.... PS....lesson learned. I will always be wireless from now on.
