Hopefully none of us thought to try this:
"The internet has happy tales of other owners reviving their dead MacBooks by gently baking them in the oven. I figured, if it’s good enough for those four people on the internet - it’s good enough for me. The idea is to heat the logic board just enough to reflow solder any broken connections.
Only the logic board should go in the oven, so the first stage is to remove all components and connections from the board. Despite the MacBook Air’s tiny form factor, this was surprisingly simple, although it does require use of a pentalobe and Torx driver bit. The I/O board was also removed from the chassis, as my suspicion was that the offending component would likely by located on that board - plus it would give the logic board a companion during the bake-off.
Recipes suggest baking at 170 °C for 7 minutes. The instructions are not specific about whether this is for fan ovens, whether preheating is required or whether an egg-wash should be applied beforehand. In my mind, thermal shock is also a greater concern when baking a motherboard compared to a Victoria sponge, so I opted to bake from cold. Weighing up the consequences of covering our main oven in molten MacBook, I also chose to use our standalone oven (purchased solely for extra Christmas dinner capacity) instead of our kitchen oven. There’s also the matter of fire safety, which I mitigated by placing the standalone oven within booting distance of the outside door.
Arranging the logic and I/O boards on the middle oven rack, I cranked up the dial to 170 °C and nervously waited for the oven to reach temperature. Unsurprisingly, gently baked MacBook doesn’t smell particularly delicious, but thankfully I’d prepared for this in advance by placing the oven in an isolated room with a door to the outside kept wide open. Six minutes into the bake, everything was still looking cushty. A few small wires had started going a bit gooey, but I was positive that the boards would survive."
