      did you find a solution to the problem?

      The screen turns on late, the fans spin at high speed and the device turns off. The original file is attached.

        The problem is caused by the RT8816A pwm control IC located next to the video card.

            My problem is hardware related.
            Changing 7J= fixed the problem.
            Thanks again for your interest.
