I replaced the thermal paste, the MacBook died 2hrs later
I changed the thermal paste of my Macbook Pro 15” MID 2014 because I was experiencing high temperatures during rendering and I thought it might help after 5 years of use.
The replacement was completed. I turned on the MacBook again and everything was fine. I’ve been working for a few hours, then the system frozen and it restarted into a boot chime loop. I turned off the MacBook by pressing the power button. Since then, it’s almost dead.
I say “almost” because the only thing working are the fans. Tried connecting the magsafe and I can reset the SMC (I get the blinking LED on the magsafe connector) so I’m sure that the keyboard is working. Also the display is working, because sometimes, if I disconnect and reconnect the battery, I get the ‘out of battery’ notice.
Also, if I connect the magsafe, the MacBook turns on by itself and you can hear the fan starting spinning. Apart from this, nothing happens. The heatsink starts getting hot as well.What happened?!
UPDATE (02/03/2021)
The thermal paste I’ve used is Thermal Grizzly Kryonaut.I think the first time I applied it, there was a little bit too much.
So I decided to remove the black sticker because I assumed that some of the original thermal paste was still underneath, and I was right. You clearly see the two layers here.
The Grizzly was a 1g pack, so I had to buy another one, and I’ve got the Arctic MX-4 now. I cleaned everything and I reapplied. This is how it looks now
UPDATE (02/04/2021)
I have some news. I did a deep cleaning on the CPU.
The one thing you were mentioning was not “wet”, but some glue residue from the black adhesive I removed. I cleaned everything and I tried also to remove all the TIM deposits between the small chips. Then I reapplied a very small portion of TIM.
I tried to turn on the MacBook. It’s still not working, but this time (it happened a very few times in these days) it showed me the “out of battery” alert. I tried connecting the Magsafe (Once again, it turns on by itself as soon as I connect the power supply) but nothing happens. Fans running at minimum speed and nothing happening.
Es esta una buena pregunta?

Time to assess your TIM who's did you use and you'll need to pop off the heatsink to inspect how it laid. Take some pictures before you clean it off so we can see what got covered Agregar imágenes a una pregunta existente

Added the images now. Thanks for your time. There's still some glue on the borders, but I don't think this is causing the boot problem since the glue was there since day 1 to hold the black sticker.
