Hi fellas,
I have his weird issue With Macbook pro 15" 2015, 2,8ghz proc. When you hear chime there is immediaetly Apple logo on the screen and non of the hotkey combinations at boot dont work.... CMD+R, D, ALT, CMD+OPT+P+R.... When its on the charger i can reset smc - Shift+opt+cmd+power, so i suppose the keyboard works... i have also tried with another keyboard connected to the board and its the same. I have tried another hdd with system installed on it ... shows apple logo for about 30s and restarts. Even if i remove the disk... it shows apple logo for 30s,... and then...
