Chosen Solution
I have used a hairdryer to preheat the computer for a while (2 years or so) whenever it accidentally switched off but one day, it just wasn’t enough. After searching for help, without result, in different fora, I thought about taking the hairdryer solution to the next level. I removed the battery, turned on the oven to 50°C, put the Mac in and waited for half an hour. Guess what: it booted up just fine. Sadly, this solution worked just 1 year and now, after the machine accidentally switched off again, I can’t power up. There’s no reaction from the computer when I push the button. With or without the battery or the charger. What can I do?
Sadly the hair dryer or oven trick doesn’t really fix the issue. You see the solder on the chips has broken down. You need to replace the solder on the chips which is a lot of work! Review this article which explains things: Inquirer claims MacBook Pros may use problematic NVIDIA chips. Sadly, Apple has EoL this system last May ‘13 so they will not repair your system. If you had gotten your system in before Oct ‘12 you would have had a free replacement of the logic board. Apple after that date charged a flat bench fee swapping the logic board until May ‘13 when they stopped repairing this model altogether. If you can find someone with good SMT soldering skills they should be able to remove the two NVIDIA chips and re-ball them with the correct high heat solder. If they check the rev of the chips they may find you have an older version of the GPU chip which runs hotter. See if they can swap it out with the newer lower temp version. After doing this you should get 5 - 10 more years of life ;-}
