When it gets warm, I hold the power button for 10 seconds then press it again once before it successfully boots up. But it gradually warms up after pushing the power button. It makes the sound when I connect the charger. When I open the lid it "turns on", I can hear the fans if I touch my ear on the bottom (Sometimes they turn very fast), but as i said, no video, no touchbar or keyboard signals. My MacBook Pro does not start up when cold. In the other assistance the same happened. After 2 weeks the technician gave up, and said that in the voltage tests everything was ok, I couldn't identify the problem. Some capacitors were changed but did not solve the problem. After cleaning the problem still persisted. The technician said that the computer had small points of oxidation and that it would clean and give the chemical bath on the plate. After my disappointment with Apple's technical support, I took him on two other third-party assistance. I took it to Apple, unfortunately apple support in Brazil is terrible, the problem was not detected and the logic board was condemned, causing them to charge an absurd amount to exchange it.
If I put it to restart or shut down and try to turn it on after a few minutes it will turn on normally, but if a long time passes the problem will come back. I did tests with third-party applications and using apple's diagnostics (holding the D key at startup), and no problems were detected.Īs I said earlier, after I get the computer to turn on everything works normally. After several attempts and after trying several key combinations the apple logo appears and the computer turns on normally with everything working. The only way to make the computer start is to press the power button several times while I connect and disconnect the charger cable. I tried to reset the SMC and NVRAM but it didn't solve the problem.

(I know it is on because I hear the fan running, sometimes slowly and sometimes at full speed). When pressing the button to turn on the computer turns on but does not display anything on the screen or lights on the keyboard. I apologize for the mistakes in English, I don't write fluently.

Mac only turns on if you plug in the charger and press the power button at the same time
