Hi You-Sheng, I have attached the 'acpi-dump' results here. By the way, I also found my laptop only has dummy output as sound.
The touchpad detection problem and the output sound problem also occur in Ubuntu 18.04 LTS (Bionic Beaver). However, they works smoothly in Windows 10. Thank you so much for your time and assistance!
