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 muc
Please attach your acpi dump for inspection:
$ sudo apt install acpica-tools
$ sudo acpidump -o acpi-dump.bin
