comment How to permanently disable (defective) graphics card in MacBook Pro?
Yes I bought the t5, t6 and mini phillips screwdrivers, after 6 months I had to reflow again(6th time) and this time it took 1 hour and 15 minutes from shutdown to restart. The actual reflow process took 5 minutes. cleaning off the old heat compound took the longest :-P My heatgun (which I bought so I wouldn't spend $1000 on a logic board) goes from 100 to 380ºC I do : 1 minute 100C, 1 minute 200C, 30s 300C, 30s 380C, then cool @ 30s 300C, 30s 200C and 1minute back at 100ºC I made it up but I read somewhere that that kinda how its done at the factory, progressive heating and cooling, GOODLUCK!

What if you have autologin(no password)? Should you skip steps 2&3.

Based on Darth's answer it seems the trick here is to shutdown in an unpowered state so the intel card becomes default.

I am on the fifth month of my last solder reflow, I used Artic Silver heat compound this time and it did wonders, it even stood up to mining crypto currencies :-) I have to completely remove my logic board and wrap it in aluminum foil (except for the graphics chip). I then apply heat from a hot air gun (bought on amazon) for about 5 mins or more. Use the arctic silver to reconnect the heat sinks then you are good to go

@Samoth try Ivan's Solution below, but the real fix is to either replace the logic board or to do a solder reflow (which may void your warranty and they may even refuse to fix it even after the warranty has ended). If you do, ensure you use arctic silver heat compound.

So after over heating, it starts back up? Does it skip the white screen?
