Without the schematics is very complicated but maybe you will be able to find the problem applying voltage on the main lines after remove the KBC and the Q47 .
Good Luck

Hi everyone, the above mentioned laptop does not respond to the power switch. I noticed that Q47 (in picture) was overheating and the KBC (KB3940Q-A1) was warming up so I changed both but they are still behaving the same way. I only have schematic for Rev:1a which does not include Q47. 3v and 5v are present. Any help will be appreciated. Вложение: r33.jpg
