My 2011 Macbook Pro 17″ failed again. A few years back, the GPU went bad so I sent it to a guy in the UK that replaced the GPU, and then it worked for maybe two years. It failed again a couple of months back, but I don’t think it’s worth having it repaired now. I did, however, just do a reflow on it for kicks. It didn’t fix the computer, though, but that won’t stop me from describing what I did. So this is an example of what doesn’t work.
