Thermal paste replacement gone wrong?
My MacBook got very hot especially in the cpu area while just browsing safari with 1-2 tabs open and no other apps running, so I thought it would be time to replace the thermal paste after 7 years. After replacing the thermal paste on the 2019 MacBook Pro with Intel i5 (A1989) it now won’t turn on.
I used this ifixit manual and followed every step the way it’s described. Before working on the MacBook I discharged the static by touching unpainted metal. I used Arctic MX-4 as the new thermal paste. The old one was practically dust and I cleaned the cpu and cooler with 99% isopropyl.
Right after finishing the repair the MacBook wouldn’t turn on. I doesn’t give any sign of life. I also unplugged the battery and connected the power cord but it didn’t work either.
What could be the reason for not turning on? I connected everything back (photo). Did I forget something or did I kill my MacBook?
