Cannot reboot or shut down completely

Hello everyone, I installed the x86 version on a 10.-inch tablet. It works except for the following 2 problems:

  1. The built-in sound card cannot be recognized and can only use USB DAC
  2. It cannot be restarted or completely shut down and shut down. In the end, there was light in the screen, but no image, and it remained like this.
    The appearance of the platform computer is more convenient and more beautiful than the PI+ external screen. Can anyone help solve the problem?Thanks!
