My 2008 MBP had a motherboard failure due to bad factory solder, but you could sometimes fix it by taking the motherboard out and putting it in the oven for just the right amount of time to reflow it. I still remember how scary it was putting the logic board in the oven - but it wasn't really bravery, when the alternative was a non-functional laptop anyway. I did eventually give up on it after it had relapsed two or three times.

My MBP had the same issue and was eligible for a replacement but since the computer couldn’t boot due to a GPU issue they couldn’t run the GPU test to verify it was a GPU issue. Even though you could clearly read the logs and tell it was the GPU.

So good, did this 3 times, everytime it would fail faster haha. Another trick was to run a benchmark, disable sleep and wrap it in some blankets until for an hour or so until the gpu solder was reflowed, didnt try that haha
